Seminario Mattia Martini - Politecnico di Milano - 28 Giugno 2024
by Luca Scarpa 18 Jun '24

18 Jun '24

Si segnala il seguente seminario a tutti gli interessati. Venerdì 28 Giugno 2024, ore 11. Aula Seminari III Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Mattia Martini, Laboratoire J.A. Dieudonné, Université Cotê d’Azur. Title: Fourier Galerkin approximation of mean field control problems. Abstract: Over the past twenty years, mean field control theory has been developed to study cooperative games between weakly interacting agents (particles). The limiting formulation of a (stochastic) mean field control problem, arising as the number of agents approaches infinity, is a control problem for trajectories with values in the space of probability measures. The goal of this talk is to introduce a finite dimensional approximation of the solution to a mean field optimal control problem set on the d-dimensional torus, without relying on particle-based methods. Our approximation is obtained by means of a Fourier-Galerkin method, the main principle of which is to truncate the Fourier expansion of probability measures. However, this operation has the main feature not to leave the space of probability measures invariant, which drawback is know as Gibbs’ phenomenon. We prove that the Fourier-Galerkin method induces a new finite-dimensional control problem with trajectories in the space of probability measures with a finite number of Fourier coefficients. We also present convergence results for the optimal control, trajectory, and value function, showing that our method achieves faster convergence rates than the usual particle approach, offering a more efficient alternative. This talk is based on joint work with François Delarue.

Si segnala il seguente seminario a tutti gli interessati. Giovedì 20 Giugno 2024, ore 11. Aula Seminari Mox VI Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Daniela Bertacchi, Università di Milano-Bicocca. Title: A new stochastic order applied to branching random walks. Abstract: Stochastic ordering is a powerful tool to compare random variables and processes. We introduce a new type of stochastic ordering which generalizes the germ order introduced by Hutchcroft in 2022, which uses the generating function of the process. We apply this order to compare different branching random walks on a countable space $X$. We prove that given two branching random walks with law $\mu$ and $\nu$ respectively, with $\mu\ge\nu$, then in every set where there is extinction according to $\mu$, there is extinction also according to $\nu$. Moreover, in every set where there is strong local survival according to $\nu$, there is strong local survival also according to $\mu$, provided that the supremum of the global extinction probabilities, for the $\nu$-process, taken over all starting points $x$, is strictly smaller than 1. New conditions for survival and strong survival for inhomogeneous branching random walks are provided. We also extend a result of Moyal (1962), on the properties of fixed points of the generating function of a branching random walk.

Ricevo e inoltro volentieri. G From: Andrea Ghiglietti <andrea.ghiglietti(a)unimib.it> Date: Friday, 14 June 2024 at 11:52 To: Giacomo Aletti <giacomo.aletti(a)unimi.it> Subject: Seminar Prof. William F Rosenberger @unimib Dear all, you are invited to participate to the following seminar on Tuesday 25th of June 2024 at 11:00 at University of Milano-Bicocca (Via Bicocca degli Arcimboldi 8 - Milano - Room 2062, Building U7, 2nd floor): Speaker: William F. Rosenberger (George Mason University) Title: Casual Inference for Clinical Trails*: A Spellchecker’s Guide to Randomization Tests in Complex Settings Sir Austin Bradford Hill, the developer of the first randomized clinical trial, was a proponent of simplicity in statistical analysis, and strongly emphasized careful study design as the critical component of all medical studies. While he didn’t mention randomization tests in his 1937 book, I believe he would have liked their simplicity and interpretability. Any inference procedure which assumes random sampling from a population ignores Fisherian principles regarding the analysis of designed experiments. And clinical trials are the quintessential designed experiment. While we hear quite often about preservation of type I error rates and, more recently, about causal inference, these are natural elements of a randomization test. We discuss these issues and demonstrate that randomization tests can be used for more complex settings, such as multiple (>2) treatment comparisons, analyses with missing outcome data, and subgroup analyses. It is interesting to note that the only cohort of statisticians NOT excited about randomization tests in this age of causal inference are the designers and conductors of randomized clinical trials! I will conclude with a few historical notes about Fisher and de Finetti*. *The two most often misspelled words during my term as Biometrics co-editor.

Seminar Prof. William F Rosenberger :: Friday, 14 June 2024 (Sapienza University of Rome)
by Nina Deliu 12 Jun '24

12 Jun '24

Cari colleghi, Ho il piacere di segnalare il seguente seminario organizzato dal Dipartimento MEMOTEF, Università degli Studi di Roma La Sapienza. *Data:* Venerdì 14 Giugno, ore 16.00-17.00 *Relatore: *Prof. William Fisher Rosenberger, Distinguished Professor in Mathematical Statistics @ George Mason University, USA *Titolo:* *Casual** Inference for Clinical *Trails**: A Spellchecker’s Guide to Randomization Tests in Complex Settings *Abstract:* Sir Austin Bradford Hill, the developer of the first randomized clinical trial, was a proponent of simplicity in statistical analysis, and strongly emphasized careful study design as the critical component of all medical studies. While he didn’t mention randomization tests in his 1937 book, I believe he would have liked their simplicity and interpretability. Any inference procedure which assumes random sampling from a population ignores Fisherian principles regarding the analysis of designed experiments. And clinical trials are the quintessential designed experiment. While we hear quite often about preservation of type I error rates and, more recently, about causal inference, these are natural elements of a randomization test. We discuss these issues and demonstrate that randomization tests can be used for more complex settings, such as multiple (>2) treatment comparisons, analyses with missing outcome data, and subgroup analyses. It is interesting to note that the only cohort of statisticians NOT excited about randomization tests in this age of causal inference are the designers and conductors of randomized clinical trials! I will conclude with a few historical notes about Fisher and de Finetti. *The two most often misspelled words during speaker's term as Biometrics co-editor Il seminario si terrà in *Aula 1 - GINI, Edificio di Scienze Statistiche*, piano terra, CU002, Città Universitaria, e potrà essere altresì seguito online via Zoom. https://uniroma1.zoom.us/j/82089465970 Meeting ID: 820 8946 5970 -- Passcode: 140624Bill Saluti, N *Nina Deliu* Assistant Professor (RTDA) in Statistics – *MEMOTEF, Sapienza Università di Roma* Research Visitor* – Biostatistics Unit, University of Cambridge* Personal website: *https://nina-dl.github.io/ <https://nina-dl.github.io/>* X (Twitter): @DeliuNina *Although my work pattern means that I will occasionally send emails outside normal working hours, you should not feel any pressure to respond outside of your own working pattern.* -- *Fai crescere le giovani ricercatrici e i giovani ricercatori*** *con il 5 per mille alla Sapienza* Scrivi il codice fiscale dell'Università *80209930587 **Cinque per mille <https://www.uniroma1.it/it/node/23149>*

An originality of the SUM conferences is their care for dedicating a large space of their program to tutorials covering a wide range of topics related to uncertainty management. Each tutorial provides a survey of one of the research areas in the scope of the conference. ===================== Topics of Interest ===================== We solicit papers on the management of large amounts of complex kinds of uncertain, incomplete, or inconsistent information. We are particularly interested in papers that focus on bridging gaps, for instance between different communities, between numerical and symbolic approaches, or between theory and practice. Topics of interest include (but are not limited to): Imperfect information in databases - Methods for modeling, indexing, and querying uncertain databases - Top-k queries, skyline query processing, and ranking - Approximate, fuzzy query processing - Uncertainty in data integration and exchange - Uncertainty and imprecision in geographic information systems - Probabilistic databases and possibilistic databases? - Data provenance and trust - Data summarization - Very large datasets Imperfect information in information retrieval and semantic web applications - Approximate schema and ontology matching - Uncertainty in description logics and logic programming - Learning to rank, personalization, and user preferences - Probabilistic language models - Combining vector-space models with symbolic representations - Inductive reasoning for the semantic web Imperfect information in artificial intelligence - Statistical relational learning, graphical models, probabilistic inference Argumentation, defeasible reasoning, belief revision - Weighted logics for managing uncertainty - Reasoning with imprecise probability, Dempster-Shafer theory, possibility theory - Approximate reasoning, similarity-based reasoning, analogical reasoning - Planning under uncertainty, reasoning about actions, spatial and temporal reasoning - Incomplete preference specifications - Learning from data Risk analysis - Aleatory vs. epistemic uncertainty - Uncertainty elicitation methods - Uncertainty propagation methods - Decision analysis methods - Tools for synthesizing results ======================== Submission Guidelines ======================== SUM 2024 solicits original papers in the following three categories: - Long papers (at most 14 pages, references excluded): technical papers reporting original research or survey papers - Short papers (between 4 and 7 pages, references excluded): papers reporting promising work-in-progress, system descriptions, position papers on controversial issues, or survey papers providing a synthesis of some current research trends - Extended abstracts (2 pages) of recently published work in a relevant journal or top-tier conference All SUM submissions must be formatted according to the LNCS/LNAI guidelines:https://www.springer.com/gp/computer-science/lncs/conference-pro… Papers should be submitted via EasyChair: https://easychair.org/conferences/?conf=sum2024 ============= Publication ============= Accepted long (at most 14 pages) and short papers (2-7 pages) will be published by Springer in the Lecture Notes in Artificial Intelligence (LNAI) series. Authors of an accepted long or short paper will be expected to sign copyright release forms, and one author is expected to give a presentation at the conference. Authors of accepted abstracts (2 pages) will be expected to present their work during the conference, but the extended abstracts will not be published in the LNCS/LNAI proceedings (they will be made available in a separate booklet). ========================================================================================= Organization ========================================================================================= Sébastien Destercke (Université de technologie de Compiègne), PC Co Chair Maria Vanina Martinez (IIIA-CSIC), PC Co Chair Giuseppe Sanfilippo, (University of Palermo), General/Local Chair

Seminar: Mark Steel @Ca' Foscari 13th June
by Roberto CASARIN 05 Jun '24

05 Jun '24

Dear all, We are happy to announce that our next seminar in statistics and econometrics at DEC, Ca' Foscari University, is quickly approaching: Speaker: Mark Steel (University of Warwick) Title: "Model Uncertainty in Latent Gaussian Models with Univariate Link Function (joint work with Gregor Zens)" Date and time: Thursday the 13th June, 12.15 GMT+2 Place: Meeting Room1, San Giobbe Campus, Department of Economics (DEC), Venice Abstract: We consider a class of latent Gaussian models with a univariate link function (ULLGMs). These are based on standard likelihood specifications (such as Poisson, Binomial, Bernoulli, Erlang, etc.) but incorporate a latent normal linear regression framework on a transformation of a key scalar parameter. We allow for model uncertainty regarding the covariates included in the regression. The ULLGM class typically accommodates extra dispersion in the data and has clear advantages for deriving theoretical properties and designing computational procedures. We formally characterize posterior existence under a convenient and popular improper prior and propose an efficient Markov chain Monte Carlo algorithm for Bayesian model averaging in ULLGMs. Simulation results suggest that the framework provides accurate results that are robust to some degree of misspecification. The methodology is successfully applied to measles vaccination coverage data from Ethiopia and to bilateral migration flow data between OECD countries. The talk will be streamed on Zoom at this link https://unive.zoom.us/s/89974935587 Meeting ID: 89974935587 Passcode: SteelJun24 For updates: https://www.unive.it/data/agenda/3/89253 We are looking forward to seeing you on June 13, best, rc -- Roberto Casarin, PhD Professor of Econometrics Ca' Foscari University of Venice San Giobbe 873/b - 30121 Venezia, Italy http://sites.google.com/view/robertocasarin/ https://www.unive.it/vera <https://www.unive.it/isba2024> https://www.unive.it/isba2024

Seminario Dr Alvaro Briz Redon presso Politecnico di Milano
by Laura Maria Sangalli 03 Jun '24

03 Jun '24

Si avvisa che in data 12-06-2024, alle ore 14:00 precise nell’aula Saleri, al sesto piano del Dipartimento di Matematica del Politecnico di Milano, si svolgerà il seguente seminario Dr Alvaro Briz Redon, Universitat de València Titolo: Some extensions and applications of self-exciting processes Abstract: Self-exciting processes allow modeling the occurrence of events whose rate depends on the history of the process. In particular, the triggering function is the term that determines the contribution of each event to the conditional intensity of the process. In this talk, we show some applications of self-exciting processes where the triggering function has a main role. First, a self-exciting point process model with change points in the triggering function is used for analyzing an earthquake dataset. Second, a self-exciting Poisson model whose outcomes are used for clustering NBA players and teams in terms of their scoring dynamics.

Seminari on-line del gruppo UMI - PRISMA (http://www.umi-prisma.polito.it/ <http://www.umi-prisma.polito.it/>) Ricordiamo che oggi, lunedì 3 giugno 2024, Alessandro De Gregorio (Sapienza Università di Roma) e Stefano Iacus (Harvard University) parleranno di Stimatori regolarizzati per equazioni differenziali stocastiche osservate a tempi discreti con il seguente orario: 16:00 Primo seminario 16:30 Pausa e discussione 16:45 Secondo seminario 17:15 Conclusione e discussione Trovate di seguito il riassunto. I seminari verranno trasmessi via Zoom al seguente link: https://uniroma1.zoom.us/j/82939128330 <https://uniroma1.zoom.us/j/82939128330> Meeting ID: 829 3912 8330 Vi aspettiamo numerosi, Valentina Cammarota e Francesco Caravenna %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Alessandro De Gregorio (Sapienza Università di Roma) e Stefano Iacus (Harvard University) TITOLO: Stimatori regolarizzati per equazioni differenziali stocastiche osservate a tempi discreti RIASSUNTO: Gli stimatori regolarizzati, cioè quegli stimatori che presentano dei termini di penalizzazione nella funzione di perdita, rappresentano uno strumento fondamentale nell'ambito della moderna teoria dell'apprendimento statistico. In questo seminario discuteremo problemi di stima parametrica penalizzata per equazioni differenziali stocastiche osservate a tempi discreti. Tale tema di ricerca è di recente interesse nell'ambito della statistica per processi stocastici. Nella prima parte del seminario, dopo una breve panoramica sulle tecniche di stima per equazioni differenziali stocastiche, introdurremo i modelli stocastici sparsi; ovvero si ipotizza che solo un piccolo numero di parametri determini il "vero" modello. In questo contesto è cruciale considerare degli stimatori regolarizzati che consentano di effettuare la stima e contemporaneamente la selezione del processo di diffusione. In particolare, saranno introdotti gli stimatori LASSO ed Elastic-Net e verranno discusse le loro proprietà asintotiche. La seconda parte dell'intervento sarà dedicata alle equazioni differenziali stocastiche su reti, in cui ciascun nodo della rete è un un'equazione stocastica che dipende dai nodi vicini. Questi modelli vengono introdotti poiché consentono di analizzare serie storiche ad altissima dimensione, sfruttando la struttura sparsa del grafo. Anche in questo contesto saranno introdotti e studiati stimatori penalizzati per la stima dei parametri del modello. Inoltre, la performance degli stimatori mediante sarà analizzate tramite alcune applicazioni. %%%%%%%%%%%%%%%%%%%%%%%%%%%% I seminari PRISMA hanno un formato di "colloquium" per creare un'occasione di scambio e discussione con tutta la comunità dei probabilisti e statistici italiani. Ogni giornata comprende due relatori che tengono due seminari di 30 minuti strettamente connessi, per presentare alla comunità una prospettiva sul proprio ambito di ricerca. Da quest'anno le registrazioni dei seminari vengono pubblicate sul canale YouTube dell'UMI: https://youtube.com/playlist?list=PLmySpc-jrtAMq84VH71evyqPc1hl6eEQb <https://youtube.com/playlist?list=PLmySpc-jrtAMq84VH71evyqPc1hl6eEQb> %%%%%%%%%%%%%%%%%%%%%%%%%%%%

International Conference in Venice - CALL FOR PAPERS - Deadline June 10, 2024
by Monica Billio 01 Jun '24

01 Jun '24

23nd INTERNATIONAL CONFERENCE CREDIT 2024 *The frontiers of new risks: AI, digital and sustainability transitions * Venice, Italy 3 – 4 October 2024 * * *GRETA Associati* (Venice, Italy),*CRIF* (Bologna, Italy), *European Datawarehouse *(Frankfurt am Main, Germany), *European Investment Fund* (Luxembourg), *Intesa Sanpaolo* (Milan, Italy) and *Modefinance* (Trieste, Italy) are partners in organising a Conference to be held in Venice on October 3-4, 2024. * * The CREDIT 2024 conference will bring together academics, practitioners and PhD students working in various areas of financial and socio-economic risk with the aim of creating a unique opportunity for participants to discuss research progress and policy as well as industry-relevant insights and directions for future research. CREDIT 2024 is the *twenty-third* in a series of events dedicated to various aspects of credit risk and organised under the auspices of: the *Department of Economics *and*VERA - Venice centre in Economic and Risk Analytics for public policies* - of the *Ca’ Foscari University of Venice*,*Joint Research Center European Commission*, *ABI - Italian Banking Association*, *AIAF - Associazione Italiana per l'Analisi Finanziaria*, *AIFIRM - Associazione Italiana Financial Industry Risk Managers*. Sustainability necessarily involves the adaptation of today’s business model to the dynamic nature of the current digitalised environments. Corporations need to make sure that resources, especially technology, are being used responsibly and efficiently to improve the lives of the present generations and future generations as well as strengthen their relationships with the environment as to solve sustainability-related problems such as poverty, environmental degradation, pollution and inequality. Artificial Intelligence (AI) has the potential to address these societal problems including sustainability. The climate crisis and the degradation of the physical environment are complex problems that require the most innovative and advanced solutions. The real value of AI hence lies in its ability to facilitate and foster environmental and social governance, rather just as a tool to reduce pollution, poverty and resource depletion. In the age of AI, societies depend on big data, social media, knowledge management and data science to survive and achieve these sustainability goals. AI has the potential to reshape not only finance and industry but also the whole society. There is need to understand opportunities and challenges as to properly manage all relevant risks. The organisers encourage submissions on any topic within the overall theme of the conference, with attention to *the use of AI to assess the sustainability impact of finance *(i.e. exploiting AI techniques or Big Data to bridge primary information gaps and proxy the sustainability impact) and *on how climate and digital risks may interact* (i.e. climate denial, social media and social media strategies including deepfakes). The final program will include both submitted and invited papers. Acceptances received so far from invited speakers include *Patrick Bolton *(Imperial College London), and *Roberto Rigobon* (MIT Sloan School of Management). The Conference will also include panel discussions on the major issues at stake with the views of researchers', practitioners' and policy makers. The SCIENTIFIC COMMITTEE for the Conference consists of: *Marcin Kacperczyk *(Imperial College London, Programme Chair) *Monica Billio* (Ca’ Foscari University of Venice & GRETA) *Marie Brière* (AMUNDI & Université Libre de Bruxelles) *Lucia Alessi* (Joint Research Center, European Commission) *Leonardo Gambacorta *(Bank For International Settlements) *Mila Getmansky* (Isenberg School of Management, UMass Amherst) *Christian Gollier* (Toulouse School of Economics) *Helmut Kraemer-Eis *(European Investment Fund) *Jan Pieter Krahnen *(Leibniz Institute for Financial Research SAFE & Goethe University) *Steven Ongena* (University of Zurich, Swiss Finance Institute, KU Leuven, NTNU Business School & CEPR) *Roberto Rigobon *(MIT Sloan School of Management) *Stephen Schaefer* (London Business School) *Marti Subrahmanyam *(NYU Stern Business School) CALL FOR PAPERS Those wishing to present a paper at the Conference should submit by *June 10, 2024 *to the address given below (preferably in electronic format). Please indicate to whom correspondence should be addressed. Decisions regarding acceptance will be made by July 10, 2024. The final version of accepted papers must be received by August 31, 2024.

Seminario Padova - Francesca Primavera
by alekos.cecchin＠unipd.it 01 Jun '24

01 Jun '24

Buongiorno a tutti, Vorremmo segnalarvi che venerdì prossimo (7 Giugno) alle ore 14:15 in aula 2AB45 (Torre Archimede, Università di Padova) ci sarà un seminario per il ciclo di seminari in Probabilità e Finanza di: Francesca Primavera (Università di Vienna) https://quarimafi.univie.ac.at/about-us/francesca-primavera/ Title: Functional Itô formula and Taylor expansion for non-anticipative maps of rough paths Date: June 7, 2024, at 14:15, 2AB45 Abstract: We rely on the approximation properties of the signature of càdlàg rough paths to derive a functional Itô formula for non-anticipative maps of rough paths. This leads to a functional extension of the Itô formula for càdlàg rough paths (by Friz and Zhang (2018)) which coincides with the change of variable formula formulated by Dupire (2009) as well as by Cont and Fournie (2010), whenever the notions of the regularity of the functionals and the integration coincide. As a byproduct, we show that sufficiently regular non-anticipative path functionals admit a functional Taylor expansion, leading to a far reaching generalization of the recently established results by Dupire and Tissot-Daguette (2022). The talk is based on ongoing joint work with Christa Cuchiero and Xin Guo. Vi aspettiamo numerosi!

Seminario Richard Samworth - Politecnico di Milano
by Laura Maria Sangalli 29 May '24

29 May '24

Si avvisa che in data 31-05-2024, alle ore 14:30 precise al Politecnico di Milano, in aula B.51 (edificio 14), si svolgerà il seguente seminario Prof. Richard Samworth, Cambridge Titolo: Isotonic subgroup selection and its role in clinical trials Abstract: Given a sample of covariate-response pairs, we consider the subgroup selection problem of identifying a subset of the covariate domain where the regression function exceeds a pre-determined threshold. This is particularly relevant in clinical trials and other applications in the life sciences, for instance where we might want to determine a subgroup that would benefit from a vaccine or treatment. We introduce a computationally-feasible approach for subgroup selection in the context of multivariate isotonic regression based on martingale tests and multiple testing procedures for logically-structured hypotheses. Our proposed procedure satisfies a non-asymptotic, uniform Type I error rate guarantee with power that attains the minimax optimal rate up to poly-logarithmic factors. Extensions cover classification, isotonic quantile regression and heterogeneous treatment effect settings. Il link per seguire il seminario online sarà reso disponibile pochi minuti prima dell’avvio del seminario al seguente link https://mox.polimi.it/mox-colloquia-seminars-list/mox-seminars/?id_evento=2… Questa iniziativa è parte delle Ph.D. Lectures finanziate dal Dipartimento di Eccellenza, 2023-2027, Dipartimento di Milano, Politecnico di Milano.

SPASS Seminars: Sara Svaluto Ferro and Elisa Marini
by Andrea Agazzi 29 May '24

29 May '24

Dear Colleagues, We would like to invite you to the following (double) SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi (abstracts below): *Signature-based models: theory and calibration * by *Sara Svaluto Ferro* (Università di Verona) *Noise-induced oscillations for the mean-field dissipative contact process* by* Elisa Marini* (Università degli Studi di Padova) The seminars will take place on *TUE, 4.6.2024* respectively at *14:00 CET *in Aula Seminari, Dipartimento di Matematica, UNIPI *and 15:00 CET* in Aula Tricerri, Dipartimento di Matematica e Informatica "Ulisse Dini", UNIFI and both streamed online at this link <https://meet.google.com/gji-phwo-vbg>. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass <https://www.google.com/url?q=https://sites.google.com/unipi.it/spass&source…> -------------------------------------------- *Signature-based models: theory and calibration * *Abstract: Universal classes of dynamic processes based on neural networks and signature methods have recently entered the area of stochastic modeling and Mathematical Finance. This has opened the door to robust and more data-driven model selection mechanisms, while first principles like no arbitrage still apply.In the first part of the talk we focus on signature SDEs whose characteristics are linear functions of a primary underlying process, which can range from a (market-inferred) Brownian motion to a general multidimensional tractable stochastic process. The framework is universal in the sense that classical models can be approximated arbitrarily well and that the model characteristics can be learned from all sources of available data by simple methods. Indeed, we derive formulas for the expected signature in terms of the expected signature of the primary underlying process.In the second part we focus on a stochastic volatility model where the dynamics of the volatility are described by linear functions of the (time extended) signature of a primary process. Under the additional assumption that this primary process is of polynomial type, we obtain closed form expressions for the squared VIX by exploiting the fact that the truncated signature of a polynomial process is again a polynomial process. Adding to such a primary process the Brownian motion driving the stock price, allows then to express both the log-price and the squared VIX as linear functions of the signature of the corresponding augmented process. For both SPX and VIX options we obtain highly accurate calibration results.The talk is based on joint works with Christa Cuchiero, Guido Gazzani, and Janka Möller.* *Noise-induced oscillations for the mean-field dissipative contact process* *Abstract: In this talk, we will introduce a dissipative version of the contact process with mean-field interaction admitting a simple epidemiological interpretation. In particular, we will focus on the thermodynamic limit of the process, providing a law of large numbers (propagation of chaos) and a central limit theorem for the corresponding normal fluctuations.These results reveal that it is the noise, which is only present in the finite-size system and is internal to the system, that induces persistent oscillatory behaviors reminiscent of the emergence of pandemic waves in real epidemics.*

Seminar Riccardo Passeggeri @ Unimib
by Federico Camerlenghi 28 May '24

28 May '24

Dear all, we are glad to announce the next DEMS seminar: *Friday, 7th June 2024* *Time 12.00*, Seminar room 2104, Department of Economics, Management and Statistics (DEMS) Building U7, second floor, University of Milano - Bicocca The speaker is Riccardo Passeggeri from Imperial College London. *Title*: *Random signed measures* *Abstract*: In this talk I present the theory of random signed measures and its applications to Bayesian nonparametric statistics and to sparse random graphs. In particular, I provide a necessary and sufficient condition for the extension of random signed measures, which solves a 70-year-old open problem dating back to the works of Alfred Renyi. This allows us to obtain a canonical definition of a random signed measure. Further, I present a representation of completely random signed measures (CRSMs), which extends the celebrated Kingman's representation for completely random measures (CRMs) to the real-valued case. I will also discuss some examples including the Skellam point process, which we show to be equivalent to a simple signed point process with independent increments, and the Gaussian random measure. Best wishes, Federico Camerlenghi

27 May '24

Seminari on-line del gruppo UMI - PRISMA (http://www.umi-prisma.polito.it/ <http://www.umi-prisma.polito.it/>) I seminari PRISMA hanno un formato di "colloquium" per creare un'occasione di scambio e discussione con tutta la comunità dei probabilisti e statistici italiani. Ogni giornata comprende due relatori che tengono due seminari di 30 minuti strettamente connessi, per presentare alla comunità una prospettiva sul proprio ambito di ricerca. Da quest'anno le registrazioni dei seminari vengono pubblicate sul canale YouTube dell'UMI: https://youtube.com/playlist?list=PLmySpc-jrtAMq84VH71evyqPc1hl6eEQb <https://youtube.com/playlist?list=PLmySpc-jrtAMq84VH71evyqPc1hl6eEQb> Il prossimo appuntamento è per lunedì 3 giugno 2024. I relatori saranno Alessandro De Gregorio (Sapienza Università di Roma) e Stefano Iacus (Harvard University) che parleranno di Stimatori regolarizzati per equazioni differenziali stocastiche osservate a tempi discreti con il seguente orario: 16:00 Primo seminario 16:30 Pausa e discussione 16:45 Secondo seminario 17:15 Conclusione e discussione Trovate di seguito il riassunto. I seminari verranno trasmessi via Zoom al seguente link: https://uniroma1.zoom.us/j/82939128330 <https://uniroma1.zoom.us/j/82939128330> Meeting ID: 829 3912 8330 Vi aspettiamo numerosi! Valentina Cammarota e Francesco Caravenna %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Alessandro De Gregorio (Sapienza Università di Roma) e Stefano Iacus (Harvard University) TITOLO: Stimatori regolarizzati per equazioni differenziali stocastiche osservate a tempi discreti RIASSUNTO: Gli stimatori regolarizzati, cioè quegli stimatori che presentano dei termini di penalizzazione nella funzione di perdita, rappresentano uno strumento fondamentale nell'ambito della moderna teoria dell'apprendimento statistico. In questo seminario discuteremo problemi di stima parametrica penalizzata per equazioni differenziali stocastiche osservate a tempi discreti. Tale tema di ricerca è di recente interesse nell'ambito della statistica per processi stocastici. Nella prima parte del seminario, dopo una breve panoramica sulle tecniche di stima per equazioni differenziali stocastiche, introdurremo i modelli stocastici sparsi; ovvero si ipotizza che solo un piccolo numero di parametri determini il "vero" modello. In questo contesto è cruciale considerare degli stimatori regolarizzati che consentano di effettuare la stima e contemporaneamente la selezione del processo di diffusione. In particolare, saranno introdotti gli stimatori LASSO ed Elastic-Net e verranno discusse le loro proprietà asintotiche. La seconda parte dell'intervento sarà dedicata alle equazioni differenziali stocastiche su reti, in cui ciascun nodo della rete è un un'equazione stocastica che dipende dai nodi vicini. Questi modelli vengono introdotti poiché consentono di analizzare serie storiche ad altissima dimensione, sfruttando la struttura sparsa del grafo. Anche in questo contesto saranno introdotti e studiati stimatori penalizzati per la stima dei parametri del modello. Inoltre, la performance degli stimatori mediante sarà analizzate tramite alcune applicazioni. %%%%%%%%%%%%%%%%%%%%%%%%%%%%

Fwd: [owps] Reminder next OWPS
by Faggionato, Alessandra 27 May '24

27 May '24

Buongiorno ricevo e con piacere inoltro. Saluti Alessandra ---------- Forwarded message --------- From: One World Probability <ow.probability(a)gmail.com> Date: Mon, 27 May 2024 at 08:40 Subject: [owps] Reminder next OWPS To: <owps(a)lists.bath.ac.uk> This is a gentle reminder that the next OWPS will be *today* from *15:00* to *17:00* *CEST *time. There will be two talks on the topic of exploration driven analysis of random graphs. The talks will touch upon general techniques and specific applications of these techniques. Title, abstract and the zoom link are below the signature and can be found on the website https://www.owprobability.org/one-world-probability-seminar <https://protect-eu.mimecast.com/s/-zGkCWqjZFlpkVlsnEyR_?domain=eur01.safeli…> . ----------------------- Talk 1 :* Mariana Olvera-Cravioto, University of North Carolina at Chapel Hill* Local limits and preferential attachment graphs This talk is meant to provide an overview of local weak convergence techniques for a large class of directed random graphs, including static models such as the Erdos-Renyi, Chung-Lu, stochastic block model, and configuration models, as well as dynamic models such as the collapsed branching process and the directed preferential attachment graph. We explain how local limits can be used to study important structural graph properties, including centrality measures such as the PageRank distribution. We further use the insights obtained from our analysis of centrality measures to explain how static models and evolving models differ in how large degree vertices are distributed within the graph and how they shape their neighborhoods. In particular, we show that the empirically accepted “power-law hypothesis” on scale-free graphs, which states that the PageRank distribution follows a power-law with the same tail index as the in-degree distribution, holds in most static models but not in the dynamic models we study. This is joint work with: Sayan Banerjee and Prabhanka Deka. Talk 2 : Sayan Banerjee, *University of North Carolina at Chapel Hill* Exploration-driven networks We propose and investigate a class of random networks where incoming vertices locally explore the graph before attaching to an existing vertex. Specific instances of these networks correspond to uniform attachment, linear preferential attachment and attachment with probability proportional to vertex PageRanks. We obtain local weak limits for such networks and use them to derive asymptotics for the limiting empirical degree and PageRank distribution. We also quantify asymptotics for the degree and PageRank of fixed vertices, including the root, and the height of the network. Two distinct regimes are seen to emerge, based on the expected exploration distance of incoming vertices, which we call the ‘fringe’ and ‘non-fringe’ regimes. These regimes are shown to exhibit different qualitative and quantitative properties. In particular, networks in the non-fringe regime undergo ‘condensation’ where the root degree grows at the same rate as the network size. Networks in the fringe regime do not exhibit condensation. Interesting phase transition phenomena are exhibited for the height of the tree and the limiting PageRank distribution. The latter connects to the well-known power-law hypothesis and the proposed class of models `interpolate’ between the PageRank behavior of static and dynamic graphs discussed in Mariana’s talk. Based on joint works with Mariana Olvera-Cravioto, Shankar Bhamidi and Xiangying (Zoe) Huang.

talk Prof. Domenico Marinucci on May 27 - DIMA - UNIGE

24 May '24

Dear all, this is a kind reminder of the following seminar Speaker : Domenico Marinucci (https://sites.google.com/view/domenicomarinucci/home) Affiliation: Dipartimento di Matematica - Università Roma Tor Vergata Title: Spectral complexity of deep neural networks Date: Monday, May 27, 2024 at 11.30 Place: Aula 704 (7th floor) , Dipartimento di Matematica at University of Genova, Via Dodencaneso 35, Teams link: https://teams.microsoft.com/l/meetup-join/19%3ameeting_NTEyMmU4MWEtZjIwOC00… Abstract: It is well-known that randomly initialized, push-forward, fully-connected neural networks weakly converge to isotropic Gaussian processes, in the limit where the width of all layers goes to infinity. In this paper, we propose to use the angular power spectrum of the limiting fields to characterize the complexity of the network architecture. In particular, we define sequences of random variables associated with the angular power spectrum, and provide a full characterization of the network complexity in terms of the asymptotic distribution of these sequences as the depth diverges. On this basis, we classify neural networks as low-disorder, sparse, or high-disorder; we show how this classification highlights a number of distinct features for standard activation functions, and in particular, sparsity properties of ReLU networks. Our theoretical results are also validated by numerical simulations.

by Mastrogiacomo Elisa 24 May '24

24 May '24

Dear all, you are invited to participate to the following seminar on Wednesday 29th of May 2024 at 12:00: Title: STOCHASTIC ORDERINGS FOR SET-VALUED RISK MEASURES Abstract: We introduce and analyze from an axiomatic point of view an extension to the set-valued scenario of the maximal correlation risk measure as defined by Burgert and Rüschendorf (2006). Furthermore, we present the notion of stochastic ordering for random vectors, utilizing the upper expectation operator - introduced in Hamel and Heyde (2021) - in conjunction with extensive classes of multidimensional functions. We then explore the consistency of such stochastic orderings for appropriate set-valued risk measures. These measures resemble the maximal correlation risk measure, offering flexibility regarding adherence to all the axioms of a portfolio aggregator and a proper set-valued risk measure. A remarkable example within this category is represented by law-invariant set-valued risk measures, such as the set-valued distortion risk measure as defined, for example, in Chen and Hu (2019). The in-person presentation will be held in Room 3 Padiglione Morselli, Via Ottorino Rossi, 9, 21100 Varese VA<https://www.google.com/maps/place//data=!4m2!3m1!1s0x478681f7697827db:0x771…>, Insubria University.

We find that market impact displays an intraday pattern superimposed with large fluctuations. Some of them are exogenous, and, as an example, we investigate market impact dynamics around FOMC announcements. Contrary to Hasbrouck (1991), we find that the information content of trades depends on the local liquidity level and the recent history of prices and trades. Finally, we use the model to estimate the time-varying permanent impact parameter, which allows performing a dynamic transaction cost analysis. Joint work with Francesco Campigli and Fabrizio Lillo. *Dr. Giuseppe Buccheri,*University of Verona, Italy https://sites.google.com/view/giuseppe-buccheri/home *Semiparametric Estimation of Volatility in the Presence of Intraday Drift Dynamics* In the conventional semimartingale representation of the log-price of a financial security, the volatility of daily log-returns is consistently estimated by their ex-post quadratic variation. A crucial assumption underlying this result is that the drift dynamics are negligible or pre-determined given past information. Recent empirical evidences of intraday unanticipated variations of mean returns call into doubt the validity of this assumption. We propose a semiparametric estimator of the daily return volatility incorporating the effect of stochastic intraday dynamics of the drift process. This framework allows us to test for the presence of drift dynamics in the data and to assess their impact on the daily return volatility. Our empirical analysis shows three main results: (i) there exists compelling evidence of intraday drift dynamics across various asset classes; (ii) when the drift moves significantly, our measure of volatility provides a better description of the return distribution; (iii) the component of the return variance associated with drift dynamics is non-negligible and possesses predictive power. Joint work with Giorgio Vocalelli. *Dr. Dario Palumbo,* Ca' Foscari University of Venice, Italy https://www.unive.it/data/people/22437798 *An Observation-Driven Generalized Poisson Model for Environmental Variables* Based on the Generalised Poisson (GP) conditional distribution, a new general class of observation-driven models for count data is presented and their theoretical properties are derived. The GP is a flexible distribution which allows for both under- and over-dispersion. As a special member of this class, a score-driven model version is introduced. We show that this specification is robust to the presence of outliers and can be extended to allow for time varying over-dispersion. For the estimation of the model we provide a Bayesian inference framework and an efficient posterior approximation procedure based on Markov Chain Monte Carlo. The applications on environmental variables show that the proposed model is well suited for capturing the over-dispersion feature of the data. *Dr. Enzo D'Innocenzo,* University of Bologna, Italy https://www.enzodinnocenzo.com/ *Limit results for score-driven filters* A study of the filtering approximation-theoretic properties of score-driven time series models. The new results are derived under a set of Lipschitz-type and tail conditions, from which I obtain maximal and deviation inequalities for the filtering approximation error. For the latter, I use techniques from empirical process theory. The novel proposed approach allows, for the first time, to study the asymptotic behavior of the empirical distribution function and the empirical processes of the approximated residuals. Since score-driven models encompasses the well-known generalized autoregressive conditional heteroskedasticity, it is proved that the results obtained in this paper extends those of Francq and Zakoian (2022) for this class of nonlinear models. In conclusion, I also give an application of these results to a popular score-driven time series models, namely, the Beta-t-GARCH(1,1) model. *Prof. Andrew Harvey,*University of Cambridge, UK *https://www.econ.cam.ac.uk/people/emeritus/ach34 <https://www.econ.cam.ac.uk/people/emeritus/ach34>* *Score-driven models: overview and recent developments* Score-driven <ach34(a)cam.ac.uk)Score-driven> time series models were introduced into the literature more than a decade ago. Since then progress has been made on the theory and a variety of new models have been introduced. I begin by reviewing theoretical results on stationarity and invertibility and show how these apply to moment-driven and score-driven models for dynamic location and/or scale parameters from a wide range of distributions. Issues of robustness are discussed and it is argued that quasi score-driven (QSD) models have an important role to play. The advantages of an exponential link function are stressed.

Seminario 4 giugno e visita a Milano Bandyopadhyay Antar
by Giacomo Aletti 20 May '24

20 May '24

Nell’ambito dei progetti di eccellenza, il Prof. Bandyopadhyay Antar Theoretical Statistics and Mathematics Unit Head of Indian Statistical Institute, Delhi Centre, New Delhi, India sarà a Milano nella settimana 2-9 giugno. È stato organizzato un seminario per il 4 giugno 2024 dalle ore 14.30 alle ore 15.30 in Aula Maggiore, via Celoria 2, Milano, dal titolo A classical random reinforcement model viewed differently! Abstract: In this talk, we will start by explaining a classical random reinforcement model introduced by Pólya back in 1920 which is widely known as the Pólya's urn scheme. We will then indicate several unrelated examples can be thought as following Pólya's model provided we allow ourselves a novel infinite dimensional generalization. After indicating the difficulties which arise due to absence of good mathematical (mostly algebraic) techniques to deal with infinite dimensional matrices (or appropriate linear operators), we will explain a new probabilistic technique to handle the infinite dimensional generalization. We shall define a novel stochastic process which will turn out to be Markov with respect to a new type of "time'' parameter, which instead of deterministic and unidirectional, will be random and will have a tree-type structure. We shall show that this new process and the infinite dimensional generalization of Pólya's balanced urn scheme have the same law. This will enable us to derive fairly general scaling limits for the infinite dimensional scheme and show that classical results can be easily derived without much difficulties and completely avoiding algebraic techniques. Moreover, we will show that apparently unrelated problems arising from a variety of different fields such as combinatorics, statistical physics and statistics, can be solved by using this new generalization. Il seminario è pensato per un pubblico non specialistico ed è aperto a tutti.

talk Prof. Nacira Agram on May 23, 2024 - REMINDER
by Emanuela Rosazza Gianin 20 May '24

20 May '24

Dear all, you are all invited to participate to the following seminar on *Thursday 23th of May 2024 at 15:00* in Aula Seminari Demografica 2062 at University of Milano Bicocca (via degli Arcimboldi 8, Milano - building U7, 2nd floor): Speaker: *Nacira Agram (KTH Stockholm)* Titolo: *Deep learning for conditional McKean-Vlasov Jump diffusions* Abstract: My talk focuses on using deep learning methods to optimize the control of conditional McKean-Vlasov jump diffusions. We begin by exploring the dynamics of multi-particle jump-diffusion and presenting the propagation of chaos. The optimal control problem in the context of conditional McKean-Vlasov jump-diffusion is introduced along with the verification theorem (HJB equation). A linear quadratic conditional mean-field (LQ CMF) is discussed to illustrate these theoretical concepts. Then, we introduce a deep-learning algorithm that combines neural networks for optimization with path signatures for conditional expectation estimation. The algorithm is applied to practical examples, including LQ CMF and interbank systemic risk, and we share the resulting numerical outcomes. Based on joint work with Jan Rems.

Seminario Padova - Marta Leocata
by alekos.cecchin＠unipd.it 20 May '24

20 May '24

Buongiorno a tutti, Vorremmo segnalarvi che venerdì prossimo (24 Maggio) alle ore 14:30 in aula 2AB45 (Torre Archimede, Università di Padova) ci sarà un seminario per il ciclo di seminari in Probabilità e Finanza di: Marta Leocata (Luiss University) https://sites.google.com/view/martaleocata/ Title: A MFG approach for competing firms in the Emission Trading System Date: May 24, 2024, at 14:30, 2AB45 Abstract: In this talk I will consider the problem of reducing the carbon emissions of a set of firms over a finite time horizon. Firms can trade allowances in a way that minimizes the total expected costs from abatement and trading plus a terminal quadratic penalty, and they can also choose which type of energy to use (fossil or green) to produce their goods and thus maximize profits from production. Using mean-field game theory and mean field control theory, we aim to understand how different types of market competition can influence the energy transition. This is a joint work with Giulia Livieri (LSE) and Gianmarco Del Sarto (SNS). Vi aspettiamo numerosi!

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 24 Maggio 2024, alle ore 12.00, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Speaker: Samuel Livingston (UCL UK) Title: *Robust gradient-based sampling algorithms using skew-symmetric numerical schemes* Abstract: State-of-the-art sampling algorithms for smooth continuous distributions are typically gradient-based, e.g. Langevin or Hamiltonian Monte Carlo. It is known, however, that particular features of the distribution to be sampled can cause them to be unstable/work poorly. The algorithms are typically based on a numerical simulation of some stochastic process (e.g. the overdamped Langevin diffusion), and the instability comes from the choice of numerical scheme. I will introduce a new explicit numerical scheme for diffusions, which has skew-symmetric increments, and can be used to design simple and fast sampling algorithms that are provably more robust. I will show that the resulting 'unadjusted Barker algorithm', so called because of its connection to the Barker Metropolis—Hastings algorithm of Livingstone & Zanella (JRSS B, 2022) is well-defined and converges at a geometric rate to an equilibrium which is close to the distribution of interest in many cases when the unadjusted Langevin algorithm is transient. ------------------------------------------------ Sarà possibile seguire il seminario anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/81530120491?pwd=YUV4Y2dtb1creEMvRkR5SkpmeW1sQT09> Il seminario è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats -- Pierpaolo De Blasi University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>

Carissimi colleghi, scusandomi per eventuali invii multipli, vi inoltro il seguente annuncio di seminario. Tutti gli interessati sono invitati a partecipare. Cordialmente, Enea Bongiorno -------------------------------- - data e orario: 23 maggio 2024 ore 15.00 - aula 204, campus Perrone, via Perrone, 18, Novara. Università del Piemonte Orientale. - on-line: meet.google.com/iap-gjcr-bkb Title: *Regression analysis with density functions in Bayes spaces* *Ivana Pavlů*, Palacký University Olomouc, Czech Republic *Abstract*: Regression analysis offers tools for explaining the relation between (a set of) dependent and independent variables. Recent advances extend the available response types from uni- or multivariate to functional, and more recently also distributional responses. For functional distributions, often represented through probability density functions, the Bayes space framework was developed to respect the relative information they carry. The Hilbert space structure of Bayes space enables one to utilize standard methods of functional data analysis for the use on - properly transformed - density functions. Focusing on regression analysis, it is possible to construct adequate models with densities on the side of both the dependent and independent variables. In this seminar, a brief overview of regression models for univariate densities will be presented. A closer attention will be given to the possible generalization of additive regression model for bivariate distributions. Finally, an outlook at the Bayesian inference in linear regression with probability densities will be discussed. All proposed methods will be demonstrated on real data from the fields of geochemistry and demographics. ----------------------------------- Locandina dell'evento <https://drive.google.com/file/d/1AW4P1_HNdVO7Ot70mjM-KCQLhnSSVmRi/view?usp=…> Seminari Matematici Statistici <https://seminari-ms.uniupo.it/home-page> ----------------------------------- -- Enea G.

talk Prof. Domenico Marinucci on May 29 - DIMA - UNIGE
by Ernesto De Vito 16 May '24

16 May '24

Dear all, you are all invited to participate to the following seminar. Speaker : Domenico Marinucci (https://sites.google.com/view/domenicomarinucci/home) Affiliation: Dipartimento di Matematica - Università Roma Tor Vergata Title: Spectral complexity of deep neural networks Date: Monday, May 29, 2024 at 11.30 Place: Aula 704 (7th floor) , Dipartimento di Matematica at University of Genova, Via Dodencaneso 35, Abstract: It is well-known that randomly initialized, push-forward, fully-connected neural networks weakly converge to isotropic Gaussian processes, in the limit where the width of all layers goes to infinity. In this paper, we propose to use the angular power spectrum of the limiting fields to characterize the complexity of the network architecture. In particular, we define sequences of random variables associated with the angular power spectrum, and provide a full characterization of the network complexity in terms of the asymptotic distribution of these sequences as the depth diverges. On this basis, we classify neural networks as low-disorder, sparse, or high-disorder; we show how this classification highlights a number of distinct features for standard activation functions, and in particular, sparsity properties of ReLU networks. Our theoretical results are also validated by numerical simulations.

Seminar: Bayesian network structural learning from complex survey data - P. Vicard
by Mira Antonietta 15 May '24

15 May '24

On behalf of Prof Di Serio I am sharing the following announcement ———————- The Statistical Network Science committee of the Bernoulli Society invites you to an online talk this week Thursday: Thursday May 16 2-3 pm UK time Title: Bayesian network structural learning from complex survey data Statistical Network Science Seminar Series- Bernoulli Society Speaker: Paola Vicard (Department of Economics, Università Roma Tre, Rome, Italy) Abstract: The association structure of a Bayesian network can be known in advance by subject matter knowledge or have to be learned from a database. One of the most widely used procedures is the PC algorithm consisting in carrying out several independence tests on the available data set and in building a Bayesian network according to the tests results. In case of data driven learning, the PC algorithm is based on the irremissible assumption that data are independent and identically distributed. Unfortunately, official statistics data are generally collected through complex sampling designs, then the aforementioned assumption is not met. In such a context the PC algorithm fails in learning the structure. To avoid this, the sample selection must be taken into account in the structural learning process. A modified version of the PC algorithm is proposed for inferring causal structure from complex survey data. It is based on resampling techniques for finite populations. A simulation experiment showing the robustness with respect to departures from the assumptions and the good performance of the proposed algorithm is carried out.

In particolare, si propone di utilizzare, in maniera appropriata e con la finalità di sollecitare le abilità comunicative ed argomentative, alcuni problemi e paradossi della probabilità condizionata che nel corso del tempo sono stati occasione di discussioni vivaci e intriganti. I problemi selezionati e sperimentati nel corso degli ultimi anni in classi della scuola secondaria, nei quali l'enfasi è posta soprattutto sul significato dei simboli e delle formule, forniscono anche un modo per stimolare gli obiettivi di "processo" (argomentare e dimostrare, comunicare, rappresentare, collegare) spesso trascurati a favore dei soli obiettivi di "contenuto". Una tale modalità operativa può essere d'aiuto sia agli insegnanti per mitigare le difficoltà che loro stessi soventemente riscontrano nella concettualizzazione (ovvero quella discontinuità tra i processi cognitivi degli studenti e l'astrazione) e sia agli stessi studenti per meglio orientarsi quando le circostanze della vita quotidiana sicuramente lo richiederanno. Gli interessati sono cordialmente invitati a partecipare, *Antonio Di Crescenzo* *Barbara Martinucci* *Alessandra Meoli* *Serena Spina*

OWABC Seminar: Mark Beaumont - 30th May 9am UK time
by Massimiliano Tamborrino 14 May '24

14 May '24

Dear all, the last OWABC www.warwick.ac.uk/oneworldabc<http://www.warwick.ac.uk/oneworldabc> seminar of Season 5 is quickly approaching. We are glad to announce that our next speaker is Mark Beaumont (University of Bristol), who will talk about "Model misspecification in population genomic" on Thursday the 30th May at 9am UK time. Abstract: In likelihood-free settings, problematic effects of model misspecification can manifest themselves during computation, leading to nonsensical answers, particularly causing convergence problems in sequential algorithms. This issue has been well studied in the last 10 years, leading to a number of methods for robust inference. In practical applications, likelihood-free methods tend to be applied to the output of complex simulations where there is a choice of summary statistics that can be computed. One approach to handling misspecification is to simply not use summary statistics computed from simulations of the model under the prior that cannot be matched with those observed in the data. This presentation gives a brief review of methods for observing and handling misspecification in ABC and SBI, and then discusses approaches that we have explored in a population genomic modelling framework. The talk will be streamed on MS Teams, at the link https://teams.microsoft.com/l/meetup-join/19%3ameeting_NWFkYmE2MTgtZTNiNS00… Meeting ID: 349 104 341 838 Passcode: YxPUhR We are looking forward to seeing you at the next OWABC Seminar, best, Massimiliano on the behalf of the OWABC Seminar Organisers ------ Dr. Massimiliano Tamborrino Associate Professor and Warwick International Higher Education Academy (WIHEA) Fellow Department of Statistics University of Warwick https://warwick.ac.uk/tamborrino

talk Prof. Nacira Agram on May 23, 2024
by Emanuela Rosazza Gianin 14 May '24

14 May '24

Dear all, you are all invited to participate to the following seminar on *Thursday 23th of May 2024 at 15:00* in Aula Seminari Demografica 2062 at University of Milano Bicocca (via degli Arcimboldi 8, Milano - building U7, 2nd floor): Speaker: *Nacira Agram (KTH Stockholm)* Titolo: *Deep learning for conditional McKean-Vlasov Jump diffusions* Abstract: My talk focuses on using deep learning methods to optimize the control of conditional McKean-Vlasov jump diffusions. We begin by exploring the dynamics of multi-particle jump-diffusion and presenting the propagation of chaos. The optimal control problem in the context of conditional McKean-Vlasov jump-diffusion is introduced along with the verification theorem (HJB equation). A linear quadratic conditional mean-field (LQ CMF) is discussed to illustrate these theoretical concepts. Then, we introduce a deep-learning algorithm that combines neural networks for optimization with path signatures for conditional expectation estimation. The algorithm is applied to practical examples, including LQ CMF and interbank systemic risk, and we share the resulting numerical outcomes. Based on joint work with Jan Rems.

Dear you all, the Econometrics group and the VERA centre of the Ca’ Foscari University ( https://www.unive.it/pag/35190) invite you to *Advances in Time Series Econometrics* *Half-day Workshop* *Venice May 17th, 2024Ca’ Foscari University, San Giobbe Campus, Meeting Room 1, Venezia* Program: - 9:30-10:15, *Ovielt Baltodano Lopez*, (Ca' Foscari University of Venice), Heterogeneous dynamic stochastic block models and an application to international trade - 10:15-11:00, *Alexander Simon Mayer* (Ca' Foscari University of Venice), Least squares estimation in nonstationary nonlinear cohort panels with learning from experience - 11:00-11:30, Break - 11:30-12.15, *Dario Palumbo* (Ca' Foscari University of Venice), A simple parsimonious framework for extracting and modelling the term structure of interest rates - 12:15-13:30, *Esther Ruiz* (University Carlos III of Madrid), Economic activity and climate change *Abstracts*: Ovielt Baltonado Lopez, Ca' Foscari University of Venice, Italy, https://www.unive.it/data/people/18754547 Heterogeneous dynamic stochastic block models and an application to international trade *The increasing complexity of the global economy represents a challenge for monitoring public debt risks. We propose a twofold framework by applying a Dynamic stochastic block model to a multi layer network composed of extracted debt relationships and trade ows for European countries. On the one hand, this approach allows for clusters of countries with di erent levels of debt synchronization that evolve over time and are subject to structural changes suggesting an increase in systemic risk. On the other hand, the layer dependence accounts for con icts in macroeconomic objectives. In particular, external balance and scal stability. In this sense, the network approach jointly considers interdependence between countries and the twin de cit phenomenon coherent with the composite nature of the risks in the nancial systems. We nd evidence of structural changes in the topology of the debt network during crisis, from an assortative behavior to a coreperiphery system with high interdependence among countries' debt. Moreover, the results suggest parameter heterogeneity. In stable periods unemployment (real GDP per capita) di erences lead to higher (lower) debt synchronization, while income inequality and nancial depth reduce the similarity in the debt evolution. There is no evidence of twinde cit phenomenon for the period 2003-2023.* Alexander Simon Mayer, Ca' Foscari University of Venice, Italy, https://www.unive.it/data/people/26394407 Least squares estimation in nonstationary nonlinear cohort panels with learning from experience *We discuss techniques of estimation and inference for nonstationary nonlinear cohort panels with learning from experience, showing, inter alia, the consistency and asymptotic normality of the nonlinear least squares estimator used in empirical practice. Potential pitfalls for hypothesis testing are identified and solutions proposed. Monte Carlo simulations verify the properties of the estimator and corresponding test statistics in finite samples, while an application to a panel of survey expectations demonstrates the usefulness of the theory developed.* Dario Palumbo, Ca' Foscari University of Venice, Italy, https://www.unive.it/data/people/22437798 A simple parsimonious framework for extracting and modelling the term structure of interest rates *This paper introduces a novel methodology for the extraction and modelling of the unobserved term structure of interest rates which incorporates in a single inferential framework both cross-sectional and time-series information from observed bond prices. In doing so, the paper introduces both a parametric and a semi-parametric dynamic model for the term structure which can be extended to capture also features such as heteroschedasticity in both the time and cross-section dimension, as well as the zero-lowerbound constraint. The models provide a coherent description of the term structure and outperforms current term structure extraction methods in fitting the observed bond prices surface. The models also outperform other existing dynamic term structure models in forecasting observed bond prices at one, six and twelve months horizons. Moreover, the study highlights a strong sensitivity of the forecasting errors of the existing dynamic models to the choice of the term structure extraction method used to construct the samples for the parameters’ estimation.* Prof. Esther Ruiz, University Carlos III of Madrid, Spain, https://researchportal.uc3m.es/display/inv16189 Economic activity and climate change -- Roberto Casarin, PhD Professor of Econometrics Ca' Foscari University of Venice San Giobbe 873/b - 30121 Venezia, Italy http://sites.google.com/view/robertocasarin/ https://www.unive.it/vera <https://www.unive.it/isba2024> https://www.unive.it/isba2024

Seminar Dario Trevisan at Tor Vergata 22.05
by Michele Salvi 13 May '24

13 May '24

Dear all, On Wednesday, May 22nd, at 14h30 in Aula Dal Passo of Tor Vergata Math Department, RoMaDS (https://www.mat.uniroma2.it/~rds/events.php) will host Dario Trevisan (Università di Pisa) with the seminar "Gaussian Approximation and Bayesian Posterior Distribution in Random Deep Neural Networks” Abstract: We establish novel rates for the Gaussian approximation of randomly initialized deep neural networks with Gaussian parameters and Lipschitz activation functions, in the so-called wide limit, i.e., where the sizes of all hidden layers become large. Using the Wasserstein metric and related functional analytic tools, we demonstrate the distribution of the output of a network and the corresponding Gaussian approximation are at a distance that scales inversely with the width of the network, surpassing previously established rates. Furthermore, we extend our findings to approximate the exact Bayesian posterior distribution of the network when the likelihood is a bounded Lipschitz function of the network output, on a finite training set. This includes common cases, such as the Gaussian likelihood, which is defined as the exponential of the negative mean squared error. Our inequalities thus shed light on the network's Gaussian behavior by quantitatively capturing the distributional convergence results in the wide limit. The exposition will aim to be self-contained, by introducing all the basic concepts related to artificial neural networks and Bayesian statistics to a mathematical audience. Based on arXiv:2203.07379 (joint with A. Basteri) and arXiv:2312.11737. We encourage in-person partecipation.

(PMS)^2 talk - J. Janák - may 16 at 11:15
by Carlo Orrieri 13 May '24

13 May '24

Dear colleagues, we are happy to announce the following talk Josef Janák (Università di Pavia) Parameter estimation for the stochastic heat equation with multiplicative noise from local measurements Abstract: We propose the stochastic heat equation driven by the multiplicative space-time white noise and we introduce several estimators to the diffusivity parameter that are inspired by the maximum likelihood estimator. Since our observation scheme relies on local measurements, the asymptotics of the estimators is pursued with a fixed time horizon and with the spatial resolution of the observations tending to zero. A stable central limit theorem shows that our proposed estimators are strictly consistent and asymptotically mixed normal. The performance of the estimators is demonstrated in numerical simulations. This is a joint work with Professor Markus Reiß. Date and time: Thursday May 16, 11:15-12:15 (Rome time zone) Place: Aula Beltrami, Dip. Matematica, Univ. Di Pavia.

Seminario ALOS - May 17th
by Alessandro Ramponi 13 May '24

13 May '24

Dear All, on May 17th, at 15:00, in classroom A (Building B), Department of Economics and Finance, University of Roma Tor Vergata, the following seminar will take place: Speaker: Elisa Alos (Dpt. Economia i Empresa, UPF, Barcelona) Title: On the Skew and Curvature of the Implied and Local Volatilities Abstract: In this talk, we study the relationship between the short-end of the local and the implied volatility surfaces. Our results, based on Malliavin calculus techniques, recover the recent 1/(H+3/2) rule (where H denotes the Hurst parameter of the volatility process) for rough volatilities (see F. Bourgey, S. De Marco, P. Friz, and P. Pigato, 2022), that states that the short-time skew slope of the at-the-money implied volatility is 1/(H+3/2) of the corresponding slope for local volatilities. Moreover, we see that the at-the-money short-end curvature of the implied volatility can be written in terms of the short-end skew and curvature of the local volatility and vice-versa. Additionally, this relationship depends on H.

Padova Seminars in Probability and Finance - Domenico Marinucci - 14:30, May 17th
by Alberto Chiarini 13 May '24

13 May '24

Dear all, It is our pleasure to invite you all to the Padova Seminars in Probability and Finance on May, 17th at 14:30, at the department of Mathematics in Padova for the seminar by: Domenico Marinucci (University of Rome "Tor Vergata") Title: Geometry and Topology of Spin Random Fields Date: May 17, 2024, at 14:30, 2AB45 Abstract: Spin random fields are very important in many physical applications; they can be viewed as random sections of the s-th complex tensor power of the tangent bundle of the 2-sphere. In this talk, we discuss how to characterize their expected geometry and topology. In particular, we investigate the asymptotic behaviour, under scaling assumptions, of general classes of geometric and topological functionals for (properly defined) excursion sets; we cover both the cases of fixed and diverging spin parameters s. In the special case of monochromatic fields (i.e., spin random eigenfunctions), we show how their asymptotic behaviour is non-universal; we can obtain complex versions of Berry's random waves and of Bargmann-Fock's model as subcases of a new general class, depending on the rate of divergence of the spin parameter. We shall also discuss how these random fields can be reparametrised into complex-valued random functions on the group of rotations SO(3), and we discuss the expected values of the same geometric functionals in this new framework. Based on joint works with Javier Carròn Duque, Antonio Lerario, Maurizia Rossi and Michele Stecconi. Best wishes, Alberto and Alekos

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 17 Maggio 2024, alle ore 12.00, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Speaker: Alex Munk (Georg August Universitat Gottingen) Title: *Optimal Transport Dependency* Abstract: Finding meaningful ways to determine the dependency between two random variables 𝜉 and 𝜁 is a timeless statistical endeavor with vast practical relevance. In recent years, several concepts that aim to extend classical means (such as the Pearson correlation or rank-based coefficients like Spearman’s 𝜌) to more general spaces have been introduced and popularized, a well-known example being the distance correlation. In this talk, we propose and study an alternative framework for measuring statistical dependency, the transport dependency 𝜏 ≥ 0 (TD), which relies on the notion of optimal transport and is applicable in general Polish spaces. It can be estimated via the corresponding empirical measure, is versatile and adaptable to various scenarios by proper choices of the cost function. It intrinsically respects metric and geometric properties of the ground spaces. Notably, statistical independence is characterized by 𝜏 = 0, while large values of 𝜏 indicate highly regular relations between 𝜉 and 𝜁 . Based on sharp upper bounds, we exploit three distinct dependency coefficients with values in [0, 1], each of which emphasizes different functional relations: These transport correlations attain the value 1 if and only if 𝜁 = 𝜑(𝜉), where 𝜑 is a) a Lipschitz function, b) a measurable function, c) a multiple of an isometry. Besides a conceptual discussion of transport dependency, we address numerical issues and its ability to adapt automatically to the potentially low intrinsic dimension of the ground space. Monte Carlo results suggest that TD is a robust quantity that efficiently discerns dependency structure from noise for data sets with complex internal metric geometry. The use of TD for inferential tasks is illustrated for independence testing on a data set of trees from cancer genetics. Joint work with Giacomo Nies and Thomas Staudt. ------------------------------------------------ Sarà possibile seguire il seminario anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/81354066852?pwd=a2hEZTFHMDRuZHVYQ1RGSmd0Wi82QT09> Il seminario è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats -- Pierpaolo De Blasi University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>

Seminario Karel Hron presso Politecnico di Milano
by Laura Maria Sangalli 12 May '24

12 May '24

Si avvisa che in data 15-05-2024, alle ore 11:00 precise al Politecnico di Milano, in aula Saleri (sesto piano Dipartimento di Matematica - edificio 14), si svolgerà il seguente seminario Karel Hron, University Olomouc Titolo: Analysing multivariate densities in Bayes spaces with implications for functional data analysis Abstract: Probability density functions can be embedded in the geometric framework of Bayes spaces which respect their relative nature and enable further modeling and analysis. Specifically, the Hilbert space structure of Bayes spaces (whereof compositional data are one specific instance) has several important implications for classical and Bayesian inference, as well as functional data analysis. In this contribution, an orthogonal decomposition of multivariate densities in Bayes spaces using a distributional analog of the Hoeffding-Sobol identity is constructed. The decomposition is based on a reformulation of the standard (arithmetic) margins into so-called geometric margins. These are orthogonal projections into one-dimensional space of information contained in multivariate densities and coincide with the arithmetic margins in case of independence. More generally, the decomposition contains an independent part and all possible interaction terms. The orthogonality of the decomposition results in an analog of Pythagoras' Theorem for squared norms of the decomposed densities and margin-free property of the interaction terms. Because the squared norms from the Pythagoras' decomposition are essentially compositional in nature, all tools of the log-ratio methodology can be used for their statistical processing. Theoretical results will be illustrated with empirical geochemical data. This talk is based on joint work with Christian Genest and Johanna Nešlehová from McGill University, Montréal, Canada.

International Conference in Venice - CALL FOR PAPERS
by Monica Billio 12 May '24

12 May '24

23nd INTERNATIONAL CONFERENCE CREDIT 2024 *The frontiers of new risks: AI, digital and sustainability transitions * Venice, Italy 3 – 4 October 2024 * * *GRETA Associati* (Venice, Italy),*CRIF* (Bologna, Italy), *European Datawarehouse *(Frankfurt am Main, Germany), *European Investment Fund* (Luxembourg), *Intesa Sanpaolo* (Milan, Italy) and *Modefinance* (Trieste, Italy) are partners in organising a Conference to be held in Venice on October 3-4, 2024. * * The CREDIT 2024 conference will bring together academics, practitioners and PhD students working in various areas of financial and socio-economic risk with the aim of creating a unique opportunity for participants to discuss research progress and policy as well as industry-relevant insights and directions for future research. CREDIT 2024 is the *twenty-third* in a series of events dedicated to various aspects of credit risk and organised under the auspices of: the *Department of Economics *and*VERA - Venice centre in Economic and Risk Analytics for public policies* - of the *Ca’ Foscari University of Venice*,*Joint Research Center European Commission*, *ABI - Italian Banking Association*, *AIAF - Associazione Italiana per l'Analisi Finanziaria*, *AIFIRM - Associazione Italiana Financial Industry Risk Managers*. Sustainability necessarily involves the adaptation of today’s business model to the dynamic nature of the current digitalised environments. Corporations need to make sure that resources, especially technology, are being used responsibly and efficiently to improve the lives of the present generations and future generations as well as strengthen their relationships with the environment as to solve sustainability-related problems such as poverty, environmental degradation, pollution and inequality. Artificial Intelligence (AI) has the potential to address these societal problems including sustainability. The climate crisis and the degradation of the physical environment are complex problems that require the most innovative and advanced solutions. The real value of AI hence lies in its ability to facilitate and foster environmental and social governance, rather just as a tool to reduce pollution, poverty and resource depletion. In the age of AI, societies depend on big data, social media, knowledge management and data science to survive and achieve these sustainability goals. AI has the potential to reshape not only finance and industry but also the whole society. There is need to understand opportunities and challenges as to properly manage all relevant risks. The organisers encourage submissions on any topic within the overall theme of the conference, with attention to *the use of AI to assess the sustainability impact of finance *(i.e. exploiting AI techniques or Big Data to bridge primary information gaps and proxy the sustainability impact) and *on how climate and digital risks may interact* (i.e. climate denial, social media and social media strategies including deepfakes). The final program will include both submitted and invited papers. Acceptances received so far from invited speakers include *Patrick Bolton *(Imperial College London), and *Roberto Rigobon* (MIT Sloan School of Management). The Conference will also include panel discussions on the major issues at stake with the views of researchers', practitioners' and policy makers. The SCIENTIFIC COMMITTEE for the Conference consists of: *Marcin Kacperczyk *(Imperial College London, Programme Chair) *Monica Billio* (Ca’ Foscari University of Venice & GRETA) *Marie Brière* (AMUNDI & Université Libre de Bruxelles) *Lucia Alessi* (Joint Research Center, European Commission) *Leonardo Gambacorta *(Bank For International Settlements) *Mila Getmansky* (Isenberg School of Management, UMass Amherst) *Christian Gollier* (Toulouse School of Economics) *Helmut Kraemer-Eis *(European Investment Fund) *Jan Pieter Krahnen *(Leibniz Institute for Financial Research SAFE & Goethe University) *Steven Ongena* (University of Zurich, Swiss Finance Institute, KU Leuven, NTNU Business School & CEPR) *Roberto Rigobon *(MIT Sloan School of Management) *Stephen Schaefer* (London Business School) *Marti Subrahmanyam *(NYU Stern Business School) CALL FOR PAPERS Those wishing to present a paper at the Conference should submit by *June 10, 2024 *to the address given below (preferably in electronic format). Please indicate to whom correspondence should be addressed. Decisions regarding acceptance will be made by July 10, 2024. The final version of accepted papers must be received by August 31, 2024.

The state variables of the mechanism design problem are aggregate capital and the distribution of continuation utilities across agents. This gives rise to a Bellman equation in an infinite dimensional space, which we solve with mean-field techniques. We fully characterize the optimal mechanism and show that the level of risk agents must be exposed to for incentive reasons is decreasing in their initial outside utility. We extend classical welfare theorems by showing that any incentive-constrained optimal allocation can be implemented as an equilibrium allocation, with appropriate money issuance and wealth taxation by the principal.

STATISTICAL REFLECTIONS: Half-day Workshop on Statistical Methods - Ca’ Foscari University (Scientific Campus Venezia Mestre)

Dear all, the STREAM group (https://www.unive.it/pag/16818/) of the Ca’ Foscari university invites to *STATISTICAL REFLECTIONS* *Half-day Workshop on Statistical Methods* *Venice May 22, 2024* Ca’ Foscari University Scientific Campus Aula Delta 1B Via Torino 155 Venezia Mestre Program: -14:00 David Firth (University of Warwick): Compositional quasi-likelihood and logit models -14:45 Ioannis Kosmidis (University of Warwick): Consistent, tuning-free model selection in regression problems -15:30 Omiros Papaspiliopoulos (Bocconi University): Functional estimation of the marginal likelihood Abstracts: Professor David Firth University of Warwick, UK https://warwick.ac.uk/dfirth Compositional quasi-likelihood and logit models A composition vector describes the relative sizes of parts of a thing. Some important modern application areas are microbiome analysis, time-use analysis and archaeometry (to name just three). We develop model-based analysis of composition, through the first two moments of measurements on their original scale. In current applied work the most-used route to compositional data analysis, following an approach introduced by the late John Aitchison in the 1980s, is based on contrasts among log-transformed measurements. The quasi-likelihood model framework developed here provides a general alternative with several advantages. These include robustness to secondary aspects of model specification, stability when there are zero-valued or near-zero measurements in the data, and more direct interpretation. Linear models for log-contrast transformed data are replaced by generalized linear models with logit link, and variance-covariance estimation is straightforward via suitably standardized residuals. Joint work with Fiona Sammut, University of Malta. Professor Ioannis Kosmidis University of Warwick, UK https://www.ikosmidis.com Consistent, tuning-free model selection in regression problems We present a family of consistent model selection procedures for regression problems, which appropriately threshold readily available statistics after estimating the model with all covariate information. The model selection procedures rely only on standard assumptions about information accumulation that guarantee the typically expected asymptotic properties of the estimators (e.g., consistency) and require neither the selection of tuning parameters nor the fitting of all possible models. We apply our thresholding methodology in widely used statistical models (e.g. generalized linear models and beta regression), demonstrate that it is easily implementable as part of the standard maximum likelihood output, and compare its performance to existing techniques, illustrating its effectiveness. Joint work with Patrick Zietkiewicz, University of Warwick. Professor Omiros Papaspiliopoulos Bocconi University, Italy https://dec.unibocconi.eu/people/omiros-papaspiliopoulos Functional estimation of the marginal likelihood We consider the problem of exploring the marginal likelihood of low-dimensional hyperparameters from high-dimensional Bayesian hierarchical models. We provide a unified framework that connects seemingly unconnected approaches to estimating normalizing constants, including the Vardi estimator, the umbrella sampling and the Gibbs sampler. The framework requires Monte Carlo sampling from the posteriors of the high-dimensional parameters for different values of the hyperparameters on a lattice. We establish a surprising reproducing property that leads to a functional estimator of the marginal likelihood and establish consistency both fixed-lattice and lattice-infill consistency. The resultant method is highly practical, black-box with theoretical guarantees.

Given a set of points, clustering consists of finding a partition of a point set into k clusters such that the center to which a point is assigned is as close as possible. Most commonly, centers are points themselves, which leads to the famous k-median and k-means objectives. One may also choose centers to be j dimensional subspaces, which gives rise to subspace clustering. In this paper, we consider learning bounds for these problems. That is, given a set of n samples P drawn independently from some unknown, but fixed distribution D, how quickly does a solution computed on P converge to the optimal clustering of D? We give several near p optimal results. In particular, 1) For center-based objectives, we show a convergence rate of O(√k/n). This matches the known optimal bounds of [Fefferman, Mitter, and Narayanan, Journal of the Mathematical Society 2016] and [Bartlett, Linder, and Lugosi, IEEE Trans. Inf. Theory 1998] for k-means and extends it to other important objectives such as k-median. 2) For subspace clustering with j-dimensional subspaces, we show a convergence rate of O(√kj2/n). These are the first provable bounds for most of these problems. For the specific case of projective clustering, which generalizes k-means, we show a converge rate of Ω(√kj/n) is necessary, thereby proving that the bounds from [Fefferman, Mitter, and Narayanan, Journal of the Mathematical Society 2016] are essentially optimal. Nicolò Cesa-Bianchi: The mathematics of machine learning: between statistics and game theory. Machine learning is the main driving force behind the current AI revolution. To provide a solid mathematical foundation to learning systems, we must formally characterize what a machine can learn and what is the minimal amount of training data needed to achieve a desired performance. In this talk, I will describe the two main approaches to algorithmic learnability, one rooted in statistics and one in game theory, and explore their connections. Pietro Caputo: Nonlinear Monte Carlo dynamics for the Ising model: some convergence results. We introduce and analyze a natural class of nonlinear Monte Carlo dynamics for spin systems such as the Ising model. The evolution is based on the framework of mass action kinetics, which models systems undergoing collisions, and captures a number of nonlinear models from various fields, including chemical reaction networks, Boltzmann’s model of an ideal gas, recombination in population genetics and genetic algorithms. In the context of spin systems, it is a nonlinear analog of the familiar Monte Carlo method based on Markov chains, such as Glauber dynamics and block dynamics, which are by now well understood. The nonlinearity makes the dynamics much harder to analyze, and even the most basic convergence issues are far from being settled. We discuss several open problems. The main result is an optimal estimate on the rate of convergence to stationarity in a regime of high temperature. Our analysis combines tools from percolation, branching and fragmentation processes. Based on joint work with Alistair Sinclair. Francesco D’Amore: The Strong Lottery Ticket Hypothesis and the Random Subset Sum Problem. The Strong Lottery Ticket Hypothesis (SLTH) posits that randomly-initialized neural networks contain subnetworks (strong lottery tickets) that achieve competitive accuracy when compared to sufficiently small target networks, even those that have been trained. Empirical evidence for this phenomenon was first observed by Ramanujan et al. in 2020, spurring a line of theoretical research: Malach et al. (ICML ’20), Pensia et al. (NeurIPS ’20), da Cunha et al. (ICLR ’20), and Burkholz (ICML & ICLR ’22) have analytically proved formulations of the SLTH in various neural network classes and under different hypotheses. In this presentation, we provide an overview of the state-of-the-art theoretical research on the SLTH and its connection with the Random Subset Sum (RSS) problem in theoretical computer science. While previous works on the SLTH ensure that the strong lottery ticket can be obtained via unstructured pruning, we demonstrate how recent advances in the multidimensional generalization of the RSS problem can be leveraged to obtain forms of structured pruning. Additionally, we highlight how refining the RSS results would yield tighter formulations of the SLTH. This presentation is based on a joint work with A. Da Cunha and E. Natale appeared at NeurIPS 2023. Federico Fusco: The Role of Transparency in Repeated First-Price Auctions with Unknown Valuations. We study the problem of regret minimization for a single bidder in a sequence of first-price auctions where the bidder discovers the item’s value only if the auction is won. Our main contribution is a complete characterization, up to logarithmic factors, of the minimax regret in terms of the auction’s transparency, which controls the amount of information on competing bids disclosed by the auctioneer at the end of each auction. Our results hold under different assumptions (stochastic, adversarial, and their smoothed variants) on the environment generating the bidder’s valuations and competing bids. These minimax rates reveal how the interplay between transparency and the nature of the environment affects how fast one can learn to bid optimally in first-price auctions. The talk is based on a joint work with Nicolò Cesa-Bianchi, Tommaso Cesari, Roberto Colomboni, and Stefano Leonardi, which will appear at STOC 2024. Matteo Quattropani: Mixing of the Averaging process on graphs and hypergraphs. The Averaging process is a mass redistribution process over the vertex set of a graph or, more generally, a hypergraph. Given a (hyper)graph G, the process starts with a non-negative mass associated with each vertex. At each discrete time step, one of the (hyper)edges of G is sampled at random and the total mass associated with the vertices of the chosen (hyper)edge is equally redistributed among its vertices. Clearly, as time grows to infinity, the state of the system will converge to a flat configuration in which all the vertices have the same mass. This very simple process appeared in different literatures under various names, and it was introduced to the probabilistic community by Aldous and Lanoue in 2012. However, until a few years ago, there were no sharp quantitative results on the time needed to reach equilibrium. Indeed, the analysis of this process requires different tools compared to the classical Markov chain framework, and even in the case of seemingly straightforward geometries—such as the complete graph or the cycle—it can be handled only by means of nontrivial probabilistic and functional analytic techniques. During the talk, I’ll give an overview of the problem and its difficulties, present the classes of examples that are currently settled, and mention some possible future directions of investigation. Based on joint work with Pietro Caputo and Federico Sau. Guido Schaefer: To Trust or Not to Trust: Assignment Mechanisms with Predictions. The realm of algorithms with predictions has led to the development of several new algorithms that leverage (potentially erroneous) predictions to enhance their performance guarantees. The challenge here is to devise algorithms that achieve optimal approximation guarantees as the prediction quality varies from perfect (consistency) to imperfect (robustness). This framework is particularly appealing in mechanism design contexts, where predictions might convey private information about the agents. In this talk, we present our recent results on the design of truthful mechanisms that leverage predictions to achieve improved approximation guarantees for several variants of the generalized assignment problem (GAP). We consider the private graph model introduced by Dughmi and Ghosh (2010), where the set of resources that an agent is compatible with is private information. We investigate GAP in the private graph model augmented with a prediction of the optimal assignment. We give a deterministic group-strategyproof mechanism that is (1 + 1/γ)-consistent and (1 + γ)-robust for the special case of bipartite matching, where γ ≥ 1 is some confidence parameter. We also prove that this is best possible. Remarkably, our mechanism draws inspiration from the renowned Gale-Shapley algorithm, incorporating predictions as a crucial element. For more general GAP variants, we introduce a unified greedy scheme and use randomization to derive universally group-strategyproof mechanisms that achieve improved consistency and robustness guarantees in expectation. Robin Vacus: Minority Dynamics: the Short and Winding Road to Consensus. The ”minority” rule is a peculiar opinion dynamics, which prompts agents to adopt the opinion least represented in a sample – in contrast to its far more famous and natural counterpart, the majority rule. Yet, as long as the sample size is large enough and communications happen in parallel, it proves to be an efficient way to reach agreement. Moreover, contrary to traditional consensus protocols, it demonstrates extreme sensitivity to even a small number of ”stubborn” individuals, enabling fast information propagation within the group. In this presentation, I will describe an analysis of convergence time, showcase simulation results, and discuss several open problems, shedding light on what is currently understood and what remains to be explored about this fascinating dynamic. This talk is based on a recent work with Luca Becchetti, Andrea Clementi, Francesco Pasquale, Luca Trevisan and Isabella Ziccardi, that was published in SODA 2024. Xavier Mathieu Raymond Venel: Weighted average-convexity in Cooperative Games. It is well known that the Shapley value of a convex game always belongs to the core. Looking for a weaker condition than convexity insuring that the Shapley value of a game lies in the core, Inarra and Usategui (1993) relaxed the convexity assumption by introducing the notion of average convexity. Assuming that weights are associated with the players, we generalize the notion of convexity and average-convexity for cooperative TU games to the notion of weighted average-convexity. We prove that if a game is weighted average-convex, then the corresponding weighted Shapley value is in the core. We then study the relations between weighted average-convexity, core-inclusion, and communication TU-games. We exhibit necessary and sufficient conditions on the underlying graph to preserve weighted average-convexity from any communication game to the associated Myerson restricted game, extending some previous results established in Slikker (1998).

Seminario di Federico Sau a Roma Tre il 14 maggio
by Pietro Caputo 07 May '24

07 May '24

Martedì* 14 Maggio* 2024 alle ore *14:30*, Federico Sau (Università degli Studi di Trieste) terrà il seminario di Probabilità dal titolo "*Scaling limits of the averaging process*". Abstract: The averaging process on a graph is a continuous-space Markov chain, which is commonly interpreted as an opinion dynamics, a distributed algorithm, or an interface moving through a randomized sequence of deterministic local updates. Its dynamics goes as follows. Attach i.i.d. Poisson clocks to edges, and assign real values to vertices; at the arrival times of these clocks, update the values with their average. As time runs, the averaging process converges to a flat configuration, and one major problem in the field is that of quantifying the speed of convergence to its degenerate equilibrium in terms of characteristic features of the underlying graph. In this talk, after reviewing some basic properties and recent results on mixing times for the averaging process on general graphs, we focus on the discrete $d$-dimensional torus, and on some finer properties of the process in this setting. We discuss some quantitative features (e.g., limit profile, early concentration and local smoothness), and look at nonequilibrium fluctuations, a particularly interesting problem in this degenerate context lacking a non-trivial notion of local equilibrium. If time permits, we will touch on the main ideas of the proof of such scaling limits, which combine tools from Malliavin calculus in Poisson space, their probabilistic dynamic interpretations, and some new discrete-gradient estimates. Talk based on the preprints arXiv.2311.14176, arXiv.2403.02032. Il seminario si svolgerà in presenza presso il Dipartimento di Matematica e Fisica - Lungotevere Dante 376 (Blocco Aule) - *Aula M2*

Seminari on-line del gruppo UMI - PRISMA (http://www.umi-prisma.polito.it/ <http://www.umi-prisma.polito.it/>) Ricordiamo che oggi, lunedì 6 maggio 2024, Domenico Marinucci (Università di Roma Tor Vergata) e Anna Vidotto (Università di Napoli Federico II) ci parleranno di La geometria degli insiemi di escursione per campi aleatori Gaussiani e La geometria dei campi aleatori sfera-per-tempo con il seguente orario: 16:00 Primo seminario 16:30 Pausa e discussione 16:45 Secondo seminario 17:15 Conclusione e discussione Trovate di seguito il riassunto. I seminari verranno trasmessi via Zoom al seguente link: https://uniroma1.zoom.us/j/82939128330 <https://uniroma1.zoom.us/j/82939128330> Meeting ID: 829 3912 8330 Vi aspettiamo numerosi, Valentina Cammarota e Francesco Caravenna %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Domenico Marinucci (Università di Roma Tor Vergata) e Anna Vidotto (Università di Napoli Federico II) TITOLO: La geometria degli insiemi di escursione per campi aleatori Gaussiani. RIASSUNTO: Obiettivo del seminario sarà di presentare una panoramica relativamente informale su alcuni risultati nell'analisi della geometria dei campi aleatori che sono stati ottenuti negli ultimi 10 anni circa. In particolare, si inizierà ricordando i risultati sulle curvature di Lipschitz-Killing di insiemi di escursione per campi Gaussiani (la Gaussian Kinematic Formula di Adler e Taylor); si proseguirà quindi con risultati per la varianza e teoremi del limite centrale nel regime di asintotica ad alta frequenza, discutendo anche le connessioni con altri campi della probabilità (in particolare, le espansioni in caos di Wiener ed il metodo di Stein-Malliavin). Se il tempo lo permetterà, si discuterà altresì la struttura di interdipendenza tra curvature di Lipschitz-Killing e punti critici, con alcuni cenni agli sviluppi più recenti (la geometria dei fibrati aleatori) e alle motivazioni/applicazioni di questi risultati. TITOLO: La geometria dei campi aleatori sfera-per-tempo. RIASSUNTO: Obiettivo del mio seminario sarà introdurre un nuovo regime asintotico per lo studio di campi aleatori definiti sulla sfera unitaria e dipendenti dal tempo. Considereremo statistiche di diversi funzionali geometrici costruite a partire dagli insiemi di livello del campo aleatorio e definite su un arco temporale crescente. Vedremo che le loro proprietà asintotiche, in particolare varianza e distribuzione limite, dipenderanno da un’interazione tra memoria temporale e livello. Infine, discuteremo brevemente le possibili applicazioni di questi modelli e dei risultati enunciati ad uno studio statistico delle proprietà dei campi aleatori di partenza, e conseguenti risvolti pratici nel campo delle scienze del Clima. %%%%%%%%%%%%%%%%%%%%%%%%%%%% I seminari PRISMA hanno un formato di "colloquium" per creare un'occasione di scambio e discussione con tutta la comunità dei probabilisti e statistici italiani. Ogni giornata comprende due relatori che tengono due seminari di 30 minuti strettamente connessi, per presentare alla comunità una prospettiva sul proprio ambito di ricerca. Da quest'anno le registrazioni dei seminari vengono pubblicate sul canale YouTube dell'UMI: https://youtube.com/playlist?list=PLmySpc-jrtAMq84VH71evyqPc1hl6eEQb <https://youtube.com/playlist?list=PLmySpc-jrtAMq84VH71evyqPc1hl6eEQb> %%%%%%%%%%%%%%%%%%%%%%%%%%%%

Università del Piemonte Orientale "Amedeo Avogadro" - on-line: https://meet.google.com/qse-iafg-wim Title: Bayes spaces for functional data analysis of density functions: from univariate to multivariate setting Speakers: Jitka Machalova, Palacký University Olomouc, Czech Republic Karel Hron, Palacký University Olomouc, Czech Republic Alessandra Menafoglio, Politecnico di Milano, Italy Abstract: The analysis of distributional data (probability density functions or histogram data) has recently gained increasing attention in the applications. Distributional data are often observed by themselves, or as result of aggregation of large streams of data. The short course will provide an introduction to the analysis of these data using a Functional Data Analysis (FDA) approach, grounded on the perspective of Bayes spaces. These spaces are mathematical spaces whose points are densities (or, more generally, measures), which generalize to the FDA setting the Aitchison simplex for multivariate compositional data. The course will give an overview of the theory of Bayes spaces in their univariate and multivariate settings. All FDA methods, presented there, will be illustrated through examples from real case studies. The short course will provide an opportunity to gain new insight into FDA of univariate and multivariate density functions through the lens of the Bayes spaces methodology. The course is supported by the European regional section of the International Association for Statistical Computing (IASC - iasc-isi.org) an association of the International Statistical Institute (ISI - isi-web.org <https://www.isi-web.org/>). ----------------------------------- Locandina dell'evento <https://drive.google.com/file/d/1wQ32TWBG4HXppmonLnwU0HXhBRMGz3ek/view?usp=…> Seminari Matematici Statistici <https://seminari-ms.uniupo.it/home-page> ----------------------------------- -- Enea G.

(PMS)^2 talks - G. CHERUBINI and R.W. MAFFUCCI - may 9 at 14:00
by Maurizia Rossi 02 May '24

02 May '24

Dear colleagues, we are happy to announce the following two talks *Giacomo Cherubini* (INdAM & Univ. Roma La Sapienza) *From arithmetic random waves to universal quadratic forms* *Abstract: *Arithmetic random waves are eigenfunctions of the Laplacian on the torus R^2/Z^2, written as sums of sines and cosines with random coefficients. In agreement with Yau's conjecture, we know that the length of the nodal set (i.e. the zero set) is of size proportional to the square root of the eigenvalue and in 2013, Krishnapur-Kurlberg-Wigman proved an asymptotic formula for its fluctuations. In this talk we will give an overview of the situation for the torus R^n/Z^n, highlighting the link between eigenspaces and quadratic forms and arriving at the statement of the "290-Theorem", which characterizes when a positive definite integral quadratic form represents all positive integers. *Riccardo W. Maffucci* (Univ. Coventry) *Nodal intersections and correlation structure for random waves* *Abstract: *This talk is based on joint works with V. Cammarota, D. Marinucci, and M. Rossi. Several recent papers studied the ensemble of Laplace Toral eigenfunctions, and their randomisation ‘arithmetic waves’, introduced in 2007 by Oravecz-Rudnick-Wigman. These waves are related to the arithmetic of writing a number as the sum of d squares, where d is the dimension. One question is the nodal (zero) volume of the wave, in the high energy limit. Restrictions of the wave to submanifolds have also attracted recent attention. We considered the length of intersection between the nodal set, and a fixed reference surface in 3 dimensions. Expectation, and variance in a general scenario were prior work. In the generic setting we prove a CLT. We will discuss (finer order) variance and (non-Gaussian) limiting distribution in the case of ‘static’ surfaces (e.g. sphere). We will also discuss recent developments on the correlation structure between different functionals of the wave. Under certain assumptions, there is asymptotic full correlation between intersection length and nodal area. Date and time: Thursday* May 9, 14:00-15:30 (Rome time zone)* Place: *Aula 3014, Dip. Matematica e Applicazioni, Univ. Milano-Bicocca, Via R. Cozzi 55, Milano* *Webex meeting link:* https://unimib.webex.com/unimib-it/j.php?MTID=m1c4d20c1f6c3199f3682809e0f4a… *Meeting number:* 2742 624 6987 *Meeting password:* mmYN7WusD46 *These talks are part of the* *(PMS)^2: Pavia-Milano Seminar series on Probability and Mathematical Statistics* *organized jointly by the universities Milano-Bicocca, Pavia and Milano-Politecnico.* Participation is free and welcome!

Seminario Federico Cornalba - Politecnico di Milano - 2 Maggio 2024
by Luca Scarpa 02 May '24

02 May '24

Si segnala il seguente seminario a tutti gli interessati. Giovedì 2 Maggio 2024, ore 11. Aula Seminari - III Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Federico Cornalba, University of Bath. Title: Numerical and analytical aspects for stochastic equations from Fluctuating Hydrodynamics. Abstract: Large-scale systems of interacting particles are ubiquitous, with applications ranging from thermal advection phenomena to gradient descent algorithms in machine learning. While the mean-field-limit (MFL) perspective allows to efficiently characterize the ‘average’ evolution of many such particles systems (usually via PDEs), it does not incorporate a macroscopic description of the particles’ intrinsic fluctuations. The theory of Fluctuating Hydrodynamics addresses this aspect by instead describing the particle systems via stochastic PDEs which enrich the underlying MFL dynamics. For a weakly interacting multi-species system, we will discuss the interplay between MFL dynamics and associated stochastic PDE, and show that numerical discretizations of the latter can approximate the particles’ fluctuations in an accurate and efficient way. Based on joint works with Julian Fischer (IST Austria), Jonas Ingmanns (IST Austria), Claudia Raithel (TU Dresden).

Seminario di Camille Tardif a Roma Tre il 9 maggio
by Pietro Caputo 30 Apr '24

30 Apr '24

Giovedì* 9 Maggio* 2024 alle ore *14:30*, Camille Tardif (Sorbonne Université, LPSM Paris) terrà il seminario di Probabilità dal titolo "*Persistence problem for additive functionals of one-dimensional diffusion processes*". Abstract: I will present a joint work with Quentin Berger and Loïc Bethencourt. We study the asymptotics of the probability that a signed additive functional of a recurrent one-dimensional diffusion stays below some constant level for a long time. Under our hypothesis we prove that this persistence probability decreases polynomially and we find the persistence exponent. For that we decompose the diffusion into excursions and the problem is reduced to study the fluctuations of some Lévy process naturally associated with the additive functional. Il seminario si svolgerà in presenza presso il Dipartimento di Matematica e Fisica - Lungotevere Dante, 376 - *Aula L*

SPASS Seminar: Remco van der Hofstad
by Gianmarco Bet 30 Apr '24

30 Apr '24

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi: *Local and 'almost' local structure of random graphs* by *Remco van der Hofstad* (*Eindhoven University of Technology*) The seminar will take place on TUE, 07.05.2024 at 14:00 CET in Aula 102, Dipartimento di Matematica e Informatica "Ulisse Dini", Università degli Studi di Firenze, and streamed online at this link <https://meet.google.com/gji-phwo-vbg>. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass -------------------------------------------- *Abstract:* * Ever since its invention by Benjamini and Schramm, and independently by Aldous and Steele, local convergence has become an indispensable tool in random graph theory. Many properties, such as subgraph counts, clustering, degree distributions and degree-degree dependencies, but also the number of spanning trees on a graph, and, under mild extra conditions, the free energy of the Ising model, are asymptotically determined by the local limit. Even more properties are not local, yet their behavior in many random graph models is still dictated by the local limit. An example is the size of the maximal connected component, which was recently shown to be `almost' local, in the sense that the proportion of vertices in it equals the survival probability of the local limit subject to one natural necessary and sufficient condition. In this lecture, we give an overview of local convergence and the local and `almost local’ structure of random graphs. We discuss that most real-world networks are sparse, in that their average degrees are bounded, while they can be quite inhomogeneous in that vertices of very high degree may exist. For such settings, local convergence is the natural notion of graph convergence for graph sequences with diverging sizes. It describes how the proportion of vertices whose neighborhoods have a certain shape converges to a limiting value, which can be seen as the neighborhood of a vertex in a limiting infinite graph, which can be random even when the finite graph is deterministic. We then discuss consequences of local convergence for random graph sequences.*

Cari tutti, segnalo il seguente seminario di Markus Reiß. Cari saluti Enrico Priola %%%%%%%%%%%%%% -------- Přeposlaná zpráva -------- Předmět: HU Working Group Seminar Mathematical Statistics: Upcoming Talk (Online) Datum: Sun, 28 Apr 2024 21:35:28 +0200 Od: Sascha Gaudlitz <sascha.gaudlitz(a)hu-berlin.de> Komu: sascha.gaudlitz(a)hu-berlin.de Dear all, this Friday, 03.05. at 13:30, Markus Reiß will give a talk on "Statistics for SPDEs" in the "International Seminar on SDEs and Related Topics". The seminar takes place online: https://jyufi.zoom.us/j/61891007917 Meeting ID: 618 9100 7917 See here for the official announcement: http://users.jyu.fi/~chgeiss/posterofPrMarkusReiss.jpg --------------------------------------------- Speaker: Markus Reiß Title: Statistics for SPDEs Abstract: Stochastic partial differential equations (SPDEs) are used more and more often to model real-world phenomena. Currently, statistical methodology for these equations is developing rapidly. If there is not only dynamic noise, but also measurement error ('static noise'), we study estimation of coefficients in a parabolic SPDE (e.g. diffusivity, transport or source terms), either parametrically or as functions in space. The analysis exhibits a fundamentally different impact of dynamic and static noise levels. We establish minimax optimality of the convergence rates. Lower bounds are achieved by bounding the Hellinger distance between noisy SPDE observations in path space and a general framework for (linear) stochastic evolution equations in Hilbert space. This gives an information-theoretic insight which coefficients can be easier estimated than others and open problems are pointed out. Some motivation by cell motility experiments in biophysics are provided. --------------------------------------------- The full programme can be found here: https://amor.cms.hu-berlin.de/~gaudlisa/seminar.html %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% -- Enrico Priola Dipartimento di Matematica, Università di Pavia Via Adolfo Ferrata 5, 27100 Pavia tel +39 0382 985639

Seminari on-line del gruppo UMI - PRISMA (http://www.umi-prisma.polito.it/ <http://www.umi-prisma.polito.it/>) I seminari PRISMA hanno un formato di "colloquium" per creare un'occasione di scambio e discussione con tutta la comunità dei probabilisti e statistici italiani. Ogni giornata comprende due relatori che tengono due seminari di 30 minuti strettamente connessi, per presentare alla comunità una prospettiva sul proprio ambito di ricerca. Da quest'anno le registrazioni dei seminari vengono pubblicate sul canale YouTube dell'UMI: https://youtube.com/playlist?list=PLmySpc-jrtAMq84VH71evyqPc1hl6eEQb <https://youtube.com/playlist?list=PLmySpc-jrtAMq84VH71evyqPc1hl6eEQb> Il prossimo appuntamento è per lunedì 6 maggio 2024. I relatori saranno Domenico Marinucci (Università di Roma Tor Vergata) e Anna Vidotto (Università di Napoli Federico II) che parleranno di La geometria degli insiemi di escursione per campi aleatori Gaussiani e La geometria dei campi aleatori sfera-per-tempo con il seguente orario: 16:00 Primo seminario 16:30 Pausa e discussione 16:45 Secondo seminario 17:15 Conclusione e discussione Trovate di seguito il riassunto.

Valentina Cammarota e Francesco Caravenna %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Domenico Marinucci (Università di Roma Tor Vergata) e Anna Vidotto (Università di Napoli Federico II) TITOLO: La geometria degli insiemi di escursione per campi aleatori Gaussiani. RIASSUNTO: Obiettivo del seminario sarà di presentare una panoramica relativamente informale su alcuni risultati nell'analisi della geometria dei campi aleatori che sono stati ottenuti negli ultimi 10 anni circa. In particolare, si inizierà ricordando i risultati sulle curvature di Lipschitz-Killing di insiemi di escursione per campi Gaussiani (la Gaussian Kinematic Formula di Adler e Taylor); si proseguirà quindi con risultati per la varianza e teoremi del limite centrale nel regime di asintotica ad alta frequenza, discutendo anche le connessioni con altri campi della probabilità (in particolare, le espansioni in caos di Wiener ed il metodo di Stein-Malliavin). Se il tempo lo permetterà, si discuterà altresì la struttura di interdipendenza tra curvature di Lipschitz-Killing e punti critici, con alcuni cenni agli sviluppi più recenti (la geometria dei fibrati aleatori) e alle motivazioni/applicazioni di questi risultati. TITOLO: La geometria dei campi aleatori sfera-per-tempo. RIASSUNTO: Obiettivo del mio seminario sarà introdurre un nuovo regime asintotico per lo studio di campi aleatori definiti sulla sfera unitaria e dipendenti dal tempo. Considereremo statistiche di diversi funzionali geometrici costruite a partire dagli insiemi di livello del campo aleatorio e definite su un arco temporale crescente. Vedremo che le loro proprietà asintotiche, in particolare varianza e distribuzione limite, dipenderanno da un’interazione tra memoria temporale e livello. Infine, discuteremo brevemente le possibili applicazioni di questi modelli e dei risultati enunciati ad uno studio statistico delle proprietà dei campi aleatori di partenza, e conseguenti risvolti pratici nel campo delle scienze del Clima. %%%%%%%%%%%%%%%%%%%%%%%%%%%%

Dear Colleagues, please find below an invitation to the seminar that Mihail Zervos will give at Collegio Carlo Alberto (Torino) on April 29 from 12 to 13. The seminar can be attended via zoom, at the link below. Best, Luca Regis <https://4z5y5.r.sp1-brevo.net/mk/cl/f/sh/SMK1E8tHeFuBlzkcYLDa5hFz9Ao6/oGRQP…> LTI@UniTO and Fondazione Collegio Carlo Alberto are pleased to invite you to the following seminar: *April 29, 2024 | 12:00 - 13:00* *Market Equilibrium under Proportional Transaction Costs in a Stochastic Factor Model* *Mihalis Zervos (LSE)* *Abstract: *We consider an economy with two agents. Each of the two agents receives a random endowment flow. We model this cumulative flow as the stochastic integral of a deterministic function of the economy’s state, which we model by means of a general Ito diffusion. Each of the two agents has mean-variance preferences with different risk-aversion coefficients. The two agents can also trade a risky asset. We determine the agents’ optimal equilibrium trading strategies in the presence of proportional transaction costs. In particular, we derive a new free-boundary problem that provides the solution to the agents’ optimal equilibrium problem. Furthermore, we derive the explicit solution to this free-boundary problem when the problem data is such that the frictionless optimiser is a strictly increasing or a strictly increasing and then strictly decreasing function of the economy’s state.

PhD on Statistical mechanics on random graphs and algorithms
by Vanessa Jacquier 23 Apr '24

23 Apr '24

Inoltro per conoscenza. Dear colleagues, Please forward this information to any interested student. Thank you in advance! “PhD on Statistical mechanics on random graphs and algorithms” Job description Random spin systems from statistical mechanics have been successfully used to study critical behaviour at the interface of problems from mathematics, physics, biology and computer science. The measure describing the spin system gives the probability of likely configurations. Phase transitions occur when tuning a parameter of the system, in the sense that there are several Gibbs measures compatible with the microscopic interactions. In recent years, there has been enormous activity in order to study phase transitions for spin systems on random graphs by rigorously characterizing the set of Gibbs measures. Applications of such problems range from computational complexity, coding theory, to machine learning. This PhD project investigates statistical mechanics on random graphs and algorithms. The focus is on properties of the q-state Potts model, which is intimately related to random graph q-coloring and community detection problems. The project is a joint project between Prof. Remco van der Hofstad (TU/e), Dr. Noela Müller (TU/e) and Dr. Wioletta Ruszel (UU). Job requirements We are looking for a candidate that brings the following: a Master’s degree in mathematics; excellent English language and communication skills; knowledge of or affinity to physics and/or computer science is not required but considered an advantage; a demonstrable research-oriented experience, interest, or attitude. Conditions of employment A meaningful job in a dynamic and ambitious university, in an interdisciplinary setting and within an international network. You will work on a beautiful, green campus within walking distance of the central train station.

School and conference in Bielefeld: "Gradient Flows, Large Deviation Theory, and Macroscopic Fluctuation Theory“
by Benjamin Gess 23 Apr '24

23 Apr '24

Dear colleagues, We would like to draw your attention to a School and conference on "Gradient Flows, Large Deviation Theory, and Macroscopic Fluctuation Theory“ which will take place *June 17-21 2024 at Bielefeld University* and is part of the 2024 activity month "Fluctuations in interacting systems: From optimal transport and Fokker–Planck equations to fluid dynamics and SPDEs“ of the collaborative research center 1283 ( https://www.sfb1283.uni-bielefeld.de/workshops/activitymonth/2024) The overarching topic of the conference is the effective description of large systems of interacting particles and their fluctuations around their typical behaviour. This mathematical challenge is of fundamental importance in a variety of applications, ranging from mathematical modelling in the sciences, to the foundations of non-equilibrium statistical mechanics and the dynamics of modern learning algorithms. Addressing these questions involves ideas from various disciplines in mathematics and physics. The workshop will bring together both leading experts and junior researchers from various fields, such as macroscopic fluctuation theory and non-equilibrium statistical mechanics, interacting particle systems, large deviation theory, gradient flows and variational methods for partial differential equations, and stochastic partial differential equations. The program will feature lecture series and talks by leading scientists as well as opportunities for junior scientists to present their work. For more details please see https://www.sfb1283.uni-bielefeld.de/2024_MFT/ With kind regards, Matthias Erbar and Benjamin Gess -- Prof. Dr. Benjamin Gess (www.bgess.de) Universität Bielefeld <https://www.math.uni-bielefeld.de/>, Fakultät für Mathematik Max Planck Institute for Mathematics in the Sciences <http://www.mis.mpg.de/index.html>, Leipzig

OWABC - Francesca Crucinio - 2nd May 2024 9am
by Massimiliano Tamborrino 23 Apr '24

23 Apr '24

Dear all, our next OWABC seminar www.warwick.ac.uk/oneworldabc<http://www.warwick.ac.uk/oneworldabc> is quickly approaching. We are happy to announce that our next speaker is Francesca Crucinio (King's College London), who will talk about "A connection between Tempering and Entropic Mirror Descent" on Thursday the 2nd May, 9am UK time. Abstract: This work explores the connections between tempering (for Sequential Monte Carlo; SMC) and entropic mirror descent to sample from a target probability distribution whose unnormalized density is known. We establish that tempering SMC corresponds to entropic mirror descent applied to the reverse Kullback-Leibler (KL) divergence and obtain convergence rates for the tempering iterates. Our result motivates the tempering iterates from an optimization point of view, showing that tempering can be seen as a descent scheme of the KL divergence with respect to the Fisher-Rao geometry, in contrast to Langevin dynamics that perform descent of the KL with respect to the Wasserstein-2 geometry. We exploit the connection between tempering and mirror descent iterates to justify common practices in SMC and derive adaptive tempering rules that improve over other alternative benchmarks in the literature. Reference: N. Chopin, F. R. Crucinio, A. Korba, A connection between Tempering and Entropic Mirror Descent, Preprint at ArXiv: 2310.11914<https://arxiv.org/pdf/2310.11914.pdf> The talk will be streamed on MS Teams at this link https://teams.microsoft.com/l/meetup-join/19%3ameeting_YTNiMmNkZTUtYTI4Mi00… Meeting ID: 378 951 648 902 Passcode: YB8fb5 We are looking forward to seeing you on May 2, best, Massimiliano on the behalf of the OWABC Seminar organisers ------ Dr. Massimiliano Tamborrino Associate Professor and Warwick International Higher Education Academy (WIHEA) Fellow Department of Statistics University of Warwick https://warwick.ac.uk/tamborrino

Seminario Andrea Agazzi - Lunedì 22 Aprile - Sapienza Università di Roma
by Silvestri, Vittoria 16 Apr '24

16 Apr '24

Si segnala il seguente seminario: Lunedì 22 Aprile 2024, ore 16:00, Sala di Consiglio, Dipartimento di Matematica "Guido Castelnuovo", Sapienza Università di Roma. *Speaker*: Andrea Agazzi (Università di Pisa) *Title*: Random Splitting of Fluid Models: Ergodicity, Convergence and Lyapunov exponents *Abstract: *We consider a family of processes obtained by decomposing the deterministic dynamics associated with some fluid models (e.g. Lorenz 96, 2d Galerkin-Navier-Stokes) into fundamental building blocks - i.e., minimal vector fields preserving some fundamental aspects of the original dynamics - and by sequentially following each vector field for a random amount of time. We characterize some ergodic properties of these stochastic dynamical systems and discuss their convergence to the original deterministic flow in the small noise regime. Finally, we show that the top Lyapunov exponent of these models is positive. This is joint work with Jonathan Mattingly and Omar Melikechi. ******************************** Vittoria Silvestri Assistant Professor Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome ********************************

Buongiorno, *giovedì 18 Aprile alle ore 15:00,* nell'*aula 24 del Dipartimento di Scienze Statistiche, Sapienza* (ed. CU002, quarto piano) e online al link https://uniroma1.zoom.us/j/83831966596?pwd=U1pEclcrZzlFMXppcmVaL1FOaFUydz09 si terrà il seguente seminario: *Speaker: Mariarosa Mazza (Università di Roma, Tor Vergata)* *Titolo: Fractional derivatives and models: some numerical aspects* *Abstract:* Fractional derivatives are a well-established mathematical tool that has received much attention in recent decades due to their non-local behavior, proven to be useful in modeling anomalous diffusion present in various real-world phenomena. Examples include the generation and spread of electrical signals across biological excitable tissues, interactions between particles and fields within a plasma, and network dynamics in human environments. The improvement in describing these phenomena, however, results in a more challenging numerical treatment, requiring specialized strategies, e.g., in terms of discretization methods or numerical solvers. The aim of this talk is to give a little taste of the topic with a focus on the numerical linear algebra difficulties that it poses. Grazie per l'attenzione, cordiali saluti.

Seminar: Francesca Romana Crucinio April 16, 2024, DAIS - Ca' Foscari University of Venice
by Carlo Gaetan 11 Apr '24

Dear all, we are glad to announce the following *online* seminar *April 16, 2024, 12:15 PM* Zoom: https://unive.zoom.us/j/85153268624?pwd=MzBhdlA2M1B2dThJQ2Y5T0EwUE5PZz09 *Speaker*: Francesca Romana Crucinio, King's College London *Title*: A connection between Tempering and Entropic Mirror Descent *Abstract:* This talk explores the connections between tempering (for Sequential Monte Carlo; SMC) and entropic mirror descent to sample from a target probability distribution whose unnormalized density is known. We establish that tempering SMC corresponds to entropic mirror descent applied to the reverse Kullback-Leibler (KL) divergence and obtain convergence rates for the tempering iterates. Our result motivates the tempering iterates from an optimization point of view, showing that tempering can be seen as a descent scheme of the KL divergence with respect to the Fisher-Rao geometry, in contrast to Langevin dynamics that perform descent of the KL with respect to the Wasserstein-2 geometry. We exploit the connection between tempering and mirror descent iterates to justify common practices in SMC and derive adaptive tempering rules that improve over other alternative benchmarks in the literature.

Seminar Tommaso Rosati at Tor Vergata 17.04
by Michele Salvi 11 Apr '24

11 Apr '24

Dear all, On Wednesday, April 17th, at 14h30 in Aula Dal Passo of Tor Vergata Math Department, RoMaDS (https://www.mat.uniroma2.it/~rds/events.php) will host Tommaso Rosati (University of Warwick) with the seminar "Lower bounds to Lyapunov exponents of stochastic PDEs” Abstract: Inspired by problems from fluid dynamics, we introduce an approach to obtain lower bounds to Lyapunov exponents of stochastic PDEs. Our proof relies on the introduction of a Lyapunov functional for the projective process associated to the equation, based on the study of dynamics of energy level sets and on a notion of non-degeneracy of the noise that leads to high-frequency stochastic instability. We address some nonlinear problems. Joint works with A. Blessing , M. Hairer, and (in progress) with M. Hairer, S. Punshon-Smith and J. Yi. We encourage in-person partecipation.

SMF: François Delarue at Milano-Bicocca (Apr 18, 2024)
by Maurizia Rossi 10 Apr '24

10 Apr '24

Dear colleagues, I am glad to announce the following talk which is part of the *"Seminario Matematico e Fisico di Milano" *activities. Speaker: *François Delarue* (Univ. Côte d'Azur) Title:* Mean field control and games. Some prospects. * *Time and place:* April 18, 2024 - 2:00pm-3:00pm - building U5/room 3014 Dept. of Mathematics and Applications, Univ. Milano-Bicocca. *Abstract:* I will first give a brief overview of the notion of mean-field control and games. In particular, I will focus on the Eulerian formulation, through the notion of master equation, which is a nonlinear PDE on the space of probability measures. This PDE is notoriously difficult to solve, at least in a classical sense, except in cases presenting a form of convexity or monotonicity in the argument of the measure. I will then present two problems outside the convex/monotonic framework: (i) non-convex mean-field control problems and their particle approximation, (ii) mean-field games subject to certain non-standard forms of common noise. Best wishes, Maurizia Rossi -- Maurizia Rossi Dipartimento di Matematica e Applicazioni Università degli Studi di Milano-Bicocca https://mauriziarossi.wordpress.com

An afternoon on the spectral theory of pseudo-differential operators
by Enrico Scalas 08 Apr '24

08 Apr '24

Dear Colleagues, On 9 april 2024 starting from 14:00 in room 34, 4th floor of the Department of Statistical Sciences, Sapienza University of Rome, (building CU002), two seminars on non-local operators will take place. Here is the program. Please feel free to inform interested people. Best regards, Enrico Scalas -- 14:00 - 15:00 Atsuhide Ishida (Tokyo University of Science, Tokyo, Japan) Mourre inequality for non-local Schrödinger operators We consider the Mourre inequality for the following self-adjoint operator $H=\Psi(-\Delta/2)+V$ acting on $L^2(\mathbb{R}^d)$, where $\Psi: [0,\infty)\rightarrow\mathbb{R}$ is an increasing function, $\Delta$ is the Laplacian and $V: \mathbb{R}^d\rightarrow\mathbb{R}$ is an interaction potential. Mourre inequality immediately yields the discreteness and finite multiplicity of the eigenvalues. Moreover, the Mourre inequality together with the limiting absorption principle can be used to show absence of the singular continuous spectrum. In addition, Mourre inequality is also used for the proof of the minimal velocity estimate that plays an important role in scattering theory. In this talk, we report that Mourre inequality holds under a general $\Psi$ and $V$ by choosing the conjugate operator $A=(p \cdot x + x \cdot p)/2$ with $p= - i \nabla$, and that the discreteness and finite multiplicity of the eigenvalues hold. This talk is a joint work with J. Lőrinczi (Alfred Rényi Institute) and I. Sasaki (Shinshu University). 15:00 - 15:30 Coffee break 15:30 - 16:30 József Lőrinczi (Alfred Rényi Institute, Budapest, Hungary) Embedded eigenvalues for a class of non-local Schrödinger operators Generally, the spectrum of a non-local Schrödinger operator may be rather intricate, even when they are self-adjoint operators. In this talk I plan to discuss some explicit cases when positive or zero eigenvalues occur, and also address the problem more generally, aiming to describe potentials which can give rise to zero eigenvalues for massive or massless (fractional) relativistic Schrodinger operators. If time permits, I intend to explain how random processes with jumps can be used to analyse such properties. 16:30 - 18:00 Discussion time

I seminari verranno trasmessi via Zoom al seguente link: https://uniroma1.zoom.us/j/82939128330 <https://uniroma1.zoom.us/j/82939128330> Meeting ID: 829 3912 8330 Vi aspettiamo numerosi, Valentina Cammarota e Francesco Caravenna %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Emanuela Sasso (Università di Genova) e Federico Girotti (Politecnico di Milano) TITOLO: Semigruppi quantistici markoviani: decoerenza, ricorrenza e accessibilità RIASSUNTO: I semigruppi markoviani quantistici sono essenzialmente semigruppi di operatori positivi su algebre di operatori con le opportune proprietà di continuità e che rafforzano la positività. Appaiono nella letteratura fisica e fisico-matematica alla fine degli anni '60 con il nome di semigruppi dinamici quantistici nella modellizzazione e nell'analisi dei sistemi aperti in meccanica quantistica. Tuttavia, dal punto di vista matematico, costituiscono la naturale generalizzazione dei semigruppi markoviani classici, infatti questi ultimi sono semigruppi di operatori definiti su un'algebra di funzioni, cioè un'algebra di operatori che commutano tra loro. Il modo più naturale per descrivere un sistema quantistico è un’algebra di Von Neumann e la sua evoluzione come una famiglia di operatori debole*-continui, che formino un semigruppo e che abbiano la proprietà di markovianità. Se il sistema è chiuso allora la sua evoluzione è reversibile, altrimenti se interagisce con l’ambiente allora ci potrebbe essere una parte diffusiva. In Fisica, si parla di “decoerenza” quando solo una parte del sistema evolve in maniera automorfica (l’algebra priva di decoerenza, appunto) e una parte “scompare” per tempi lunghi. La nostra ricerca si è focalizzata a lungo su quale definizione di decoerenza sia più adatta e se è possibile trovare condizioni necessarie e sufficienti per il suo verificarsi. Nello studio dei processi (semigruppi) di Markov classici sono fondamentali le nozioni di ricorrenza e comunicazione tra insiemi di stati; mostreremo come questi concetti siano stati generalizzati nel caso noncommutativo e discuteremo alcune delle loro proprietà e relazioni. Particolare attenzione sarà dato al caso in cui l’algebra su cui agisce il semigruppo sia l’insieme di tutti gli operatori lineari limitati che agiscono su uno spazio di Hilbert. %%%%%%%%%%%%%%%%%%%%%%%%%%%% I seminari PRISMA hanno un formato di "colloquium", per creare un'occasione di scambio e discussione con tutta la comunità dei probabilisti e statistici italiani. Ogni giornata comprende due relatori che tengono due seminari di 30 minuti strettamente connessi, per presentare alla comunità una prospettiva sul proprio ambito di ricerca. Da quest'anno le registrazioni dei seminari vengono pubblicate sul canale YouTube dell'UMI: https://www.youtube.com/playlist?list=PLmySpc-jrtAMq84VH71evyqPc1hl6eEQb %%%%%%%%%%%%%%%%%%%%%%%%%%%%

On behalf of the Scientific Committee of the "B. de Finetti Risk Seminars, Milano Lectures on the Mathematical Theory of Economics and Finance”, we are glad to invite you to participate at the following lecture: Marcel Nutz Columbia University (New York) Title: Entropic Selection in Optimal Transport Abstract: The optimal transport problem can admit many solutions, for instance when the cost function is the Euclidean distance on R^d (Monge's problem). On the other hand, entropically regularized optimal transport (EOT) always has a unique optimizer. It is a longstanding open problem whether EOT selects some particular optimal transport coupling in the vanishing regularization limit, and what that coupling would look like. We provide a surprising answer for Monge's problem in dimension d > 1. (Joint work with Chenyang Zhong.)

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 12 Aprile 2024, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terranno i seguenti *2 seminari*: ------------------------------------------------ *11.00-12.00* Speaker: Varun Jog (University of Cambridge, UK) Title: *The sample complexity of simple binary hypothesis testing* Abstract: The sample complexity of simple binary hypothesis testing is the smallest number of i.i.d. samples required to distinguish between two distributions p and q such that the Type-I and Type-II errors are smaller than some pre-specified thresholds α and β, respectively. Our main contribution is deriving, under mild technical conditions, a formula for the sample complexity in terms of parameters p, q, alpha, and beta, that is tight up to universal multiplicative constants. ------------------------------------------------ *12.00-13.00* Speaker: Po-Ling Loh (University of Cambridge, UK) Title: *Differentially private M-estimation via noisy optimization* Abstract: We present a noisy composite gradient descent algorithm for differentially private statistical estimation in high dimensions. We begin by providing general rates of convergence for the parameter error of successive iterates under assumptions of local restricted strong convexity and local restricted smoothness. Our analysis is local, in that it ensures a linear rate of convergence when the initial iterate lies within a constant-radius region of the true parameter. At each iterate, multivariate Gaussian noise is added to the gradient in order to guarantee that the output satisfies Gaussian differential privacy. We then derive consequences of our theory for linear regression and mean estimation. Motivated by M-estimators used in robust statistics, we study loss functions which downweight the contribution of individual data points in such a way that the sensitivity of function gradients is guaranteed to be bounded, even without the usual assumption that our data lie in a bounded domain. We prove that the objective functions thus obtained indeed satisfy the restricted convexity and restricted smoothness conditions required for our general theory. We then show how the private estimators obtained by noisy composite gradient descent may be used to obtain differentially private confidence intervals for regression coefficients, by leveraging work in Lasso debiasing proposed in high-dimensional statistics. We complement our theoretical results with simulations that illustrate the favorable finite-sample performance of our methods. ------------------------------------------------ Sarà possibile seguire entrambi i seminari anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/88987605028?pwd=YXN1akl1bkN3TEFlS3QrMWFDWEF5dz09> I seminari sono organizzati dalla "de Castro" Statistics Initiative www.carloalberto.org/stats -- Pierpaolo De Blasi University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>

A major reason of this surge in applications is the popularization of Sinkhorn's algorithm to efficiently solve the entropic optimal transport problem numerically. The topic of this talk is the (rate of) convergence of Sinkhorn's algorithm. In bounded settings, it is known that Sinkhorn's algorithm converges with exponential rate, which is a consequence of applying a commonly used version of Hilbert's metric corresponding to the cone of all non-negative functions. This talk shows how to define versions of Hilbert's metric so that we can show exponential convergence of Sinkhorn's algorithm even in unbounded settings. This is done through the use of cones which are a relaxations of the cone of all non-negative functions, in the sense that they include all functions having non-negative integral values when multiplied with certain test functions. Along the way, we establish that kernel integral operators are contractions with respect to suitable versions of Hilberts metric, even if the kernel functions are not bounded away from zero.

Double Seminar: Federico Camia and Alessandra Bianchi at Tor Vergata 10.04
by Michele Salvi 04 Apr '24

04 Apr '24

Dear all, On Wednesday, April 10th, at 14h30 in Aula Dal Passo of Tor Vergata Math Department, RoMaDS (https://www.mat.uniroma2.it/~rds/events.php) will host a double seminar: 14h30 - Federico Camia (NYU Abu Dhabi) “Towards a logarithmic conformal field theory of 2D critical percolation” Abstract: Conformal field theory (CFT) provides a very powerful framework to study the large-scale properties of models of statistical mechanics at their critical point. The prototypical example of this is the continuum (scaling) limit of the two-dimensional critical Ising model. The case of critical percolation is more difficult, partly because its continuum limit is believed to be described by a relatively unusual type of CFT, called a logarithmic CFT. In this talk, I will first briefly explain the statements above. I will then present some recent results and work in progress that are part of a program aimed at fitting percolation within the logarithmic CFT framework. 15h30 - Alessandra Bianchi (Università di Padova) “Mixing cutoff for simple random walks on the Chung-Lu directed graph” Abstract: In this talk, we consider a simple random walk defined on a Chung-Lu directed graph, an inhomogeneous random network that extends the Erdos Renyi random digraph by including edges independently according to given Bernoulli laws. In this non-reversible setting, we will focus on the convergence toward the equilibrium of the dynamics. In particular, under the assumption that the average degree grows logarithmically in the size n of the graph (weakly dense regime), we will establish a cutoff phenomenon at the entropic time of order log(n)/loglog(n). We will then show that on a precise window the cutoff profile converges to the Gaussian tail function. This is qualitatively similar to what was proved in a series of works by Bordenave, Caputo, Salez for the directed configuration model, where degrees are deterministically fixed. In terms of statistical ensembles, this analysis provides an extension of these cutoff results from a hard to a soft-constrained model. Joint work with G. Passuello. We encourage in-person participation.

Seminario Eliseo Luongo - Politecnico di Milano - 4 Aprile 2024
by Luca Scarpa 03 Apr '24

03 Apr '24

Si segnala il seguente seminario a tutti gli interessati. Giovedì 4 Aprile 2024, ore 11:30. Aula Seminari Mox - VI Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Eliseo Luongo, Scuola Normale Superiore, Pisa. Title: Global Well-Posedness and Interior Regularity of 2D Navier-Stokes Equations with Stochastic Wind Driven Boundary Conditions. Abstract: Partial differential equations with boundary noise have been introduced by Da Prato and Zabczyck. They showed that, also in the one dimensional case, the solutions of the heat equation with white noise Dirichlet or Neumann Boundary conditions have low regularity compared to the case of noise diffused inside the domain. In particular, in the case of Dirichlet boundary conditions the solution is only a distribution. Some improvements in the analysis of the interior regularity of the solutions of these problems and some nonlinear variants have been obtained exploiting specific properties of the heat kernel and of suitable nonlinearities. All these issues make the problem of treating non-linear partial differential equations with boundary noise coming from fluid dynamical models an, almost untouched, field of open problems. In this talk we discuss the global well-posedness and the interior regularity of a system of 2D Navier-Stokes equations with inhomogeneous stochastic boundary conditions. The noise, white in time and coloured in space, can be interpreted as the physical law describing the driving mechanism on the atmosphere-ocean interface, i.e. as a balance of the shear stress of the ocean and the horizontal wind force. The talk is based on a joint work with A. Agresti.

Seminario Padova - Stephan Eckstein

02 Apr '24

Buongiorno a tutti, Vorremmo segnalarvi che venerdì prossimo (5 Aprile) alle ore 14:30 in aula 2AB40 (Torre Archimede, Università di Padova) ci sarà un seminario per il ciclo di seminari in Probabilità e Finanza di: Stephan Eckstein (Tübingen University) <https://sites.google.com/view/stephan-eckstein/startseite> https://sites.google.com/view/stephan-eckstein/ Title: Exponential convergence of Sinkhorn's algorithm and Hilbert's projective metric for unbounded functions Date: April 5, 2024, at 14:30, 2AB40 Abstract: Entropic regularization of optimal transport has found numerous applications in various fields recently. A major reason of this surge in applications is the popularization of Sinkhorn's algorithm to efficiently solve the entropic optimal transport problem numerically. The topic of this talk is the (rate of) convergence of Sinkhorn's algorithm. In bounded settings, it is known that Sinkhorn's algorithm converges with exponential rate, which is a consequence of applying a commonly used version of Hilbert's metric corresponding to the cone of all non-negative functions. This talk shows how to define versions of Hilbert's metric so that we can show exponential convergence of Sinkhorn's algorithm even in unbounded settings. This is done through the use of cones which are a relaxations of the cone of all non-negative functions, in the sense that they include all functions having non-negative integral values when multiplied with certain test functions. Along the way, we establish that kernel integral operators are contractions with respect to suitable versions of Hilberts metric, even if the kernel functions are not bounded away from zero. Vi aspettiamo numerosi! Alberto Chiarini e Alekos Cecchin Sito web del seminario: https://www.math.unipd.it/~chiarini/seminars/

Seminar: Laura D'Angelo April 09, 2024, Ca' Foscari University of Venice
by Carlo Gaetan 28 Mar '24

28 Mar '24

Dear all, we are glad to announce the following hybrid seminar *April 09, 2024, 12:15 PM* *Where*: Aula Delta 2C- edificio Delta (Campus Scientifico), Via Torino, 155 Mestre (Venice, Italy) Zoom: https://unive.zoom.us/j/85153268624?pwd=MzBhdlA2M1B2dThJQ2Y5T0EwUE5PZz09 *Speaker*: Laura D'Angelo, Università degli Studi di Milano-Bicocca (Italy) *Title*: Analyzing the activation patterns and heterogeneity of the neuronal response via Bayesian mixture models *Abstract:* The modern technique of calcium imaging is revolutionizing the understanding of the nervous system, thanks to its ability to image the activity of individual neurons over time in freely moving animals. This technology has led to remarkable insights into how neurons process and encode information, both individually and collectively. In this talk, we examine how Bayesian mixture models can help uncover the complex functioning of neurons in different experimental studies. First, we discuss a nested mixture model to analyze how the activity of an individual cell is affected by visual stimuli that vary over time. Then, we move to a multivariate model to identify groups of co-activating neurons, where the information on the anatomical proximity is introduced to inform the clustering procedure. At the basis of both models is a simple but effective state-space formulation that describes the calcium dynamic and relates it to the latent firing events. Through these examples, we show how the Bayesian nonparametric framework is ideal for flexibly modeling the unobserved neuronal activity, identifying patterns of activity, borrowing information across experimental conditions, and including additional knowledge.

Postdoc on the mathematics of supply chain
by Marco Scarsini 27 Mar '24

27 Mar '24

We have a postdoc position at Luiss University on the mathematics of supply chain. A supply chain is modeled as a network whose vertices are firms and whose edges represent their interactions. The network evolves dynamically, and may be affected by sudden disruptions. Many of the existing supply-chain models are static and, when dealing with disruptions, compare pre- and post-shock equilibria. In real life, the effects of disruption take time to spread across the network. Understanding this temporal element is fundamental for taking mitigating actions. The main goal of this project is to study dynamic models of supply-chain disruption. The formal analysis of this phenomenon will use tools from network theory, probability theory, game theory, operations management, optimization, dynamical systems, machine learning, data science. We are looking for a candidate who has a strong expertise in at least one of the above fields. Title of the project: A dynamic analysis of supply-chain networks and their disruption Length of the position: 36 months Gross annual salary: € 36.480,57 Application deadline: 2024/05/03, 14:00 Central European Summer Time (CEST) The call for this postdoc can be found here: https://economiaefinanza.luiss.it/uploads/2024/03/Bando-Assegno-Prof.-Scars… The candidates must submit their application online here: https://cloudserverjsa.luiss.it/LGCAssegni/index.zul?CDS=AS4239 ******************************************************* Marco Scarsini Dipartimento di Economia e Finanza Luiss University Viale Romania 32 00197 Roma, ITALY

25 Mar '24

Dear colleagues, We are happy to announce the following talk: Speaker: Simone Ferrari (Università del Salento) Title: On the domain in L^2 type spaces of elliptic operators in Banach spaces Abstract: In this talk, we will present some (almost) characterization results of the domain of elliptic operators associated with the quadratic form of suitable gradient operator in infinite dimension. When the Banach space turns out to be a Hilbert space, we will show that a similar characterization remains true for more general elliptic operators associated with semilinear stochastic partial differential equations.

Seminar: Adriano Barra at Tor Vergata 02.11
by Michele Salvi 22 Mar '24

22 Mar '24

Dear all, On Thursday, November 2nd, at 15h00 in Aula Dal Passo of Tor Vergata Math Department, RoMaDS (https://www.mat.uniroma2.it/~rds/about.php) will host Adriano Barra (Università del Salento) with the seminar "A walk in the statistical mechanics of neural networks” Abstract: Purpose of this talk is twofold: in the first part, I will provide a statistical mechanical picture of shallow networks proving how learning in biological neural networks (e.g. in the Hopfield model) and standard machine learning via gradient descent (e.g. on the Boltzmann machine) ultimately convey the same information after training. This diminishes the gap in our understanding between biological and artificial information processing networks. In the second part of the talk, focusing on a toy model for the sake of simplicity, I will show how recent mathematical techniques, heavily based on Guerra's interpolation, are suitable to describe the emergent properties of this kind of networks. We encourage in-person partecipation. Should you be unable to come, here is the link to the Teams streaming: https://teams.microsoft.com/l/meetup-join/19%3arfsL73KX-fw86y1YnXq2nk5VnZFw… <https://teams.microsoft.com/l/meetup-join/19:rfsL73KX-fw86y1YnXq2nk5VnZFwPU…> The seminar is part of the Excellence Project MatMod@TOV.

Seminar: Philipp Sterzinger March 26, 2024, Ca' Foscari University of Venice
by Carlo Gaetan 19 Mar '24

19 Mar '24

Dear all, we are glad to announce the following hybrid seminar *March 26, 2024, 12:15 PM* *Where*: Aula Delta 2C- edificio Delta (Campus Scientifico), Via Torino, 155 Mestre (Venice, Italy) Zoom: https://unive.zoom.us/j/85153268624?pwd=MzBhdlA2M1B2dThJQ2Y5T0EwUE5PZz09 *Speaker*: Philipp Sterzinger, University of Warwick *Title*: Diaconis-Ylviskaer prior penalized likelihood in high-dimensional logistic regression *Abstract:* In recent years, there has been a surge of interest in estimators and inferential procedures that exhibit optimal asymptotic properties in high-dimensional logistic regression when the number of covariates grows proportionally as a fraction ($\kappa \in (0,1)$) of the number of observations. In this seminar, we focus on the behaviour of a class of maximum penalized likelihood estimators, employing the Diaconis-Ylvisaker prior as the penalty. Building on advancements in approximate message passing, we analyze the aggregate asymptotic behaviour of these estimators when covariates are normal random variables with arbitrary covariance. This analysis enables us to eliminate the persistent asymptotic bias of the estimators through straightforward rescaling for any value of the prior hypertuning parameter. Moreover, we derive asymptotic pivots for constructing inferences, including adjusted Z-statistics and penalized likelihood ratio statistics. Unlike the maximum likelihood estimate, which only asymptotically exists in a limited region on the plane of $\kappa$ versus signal strength, the maximum penalized likelihood estimate always exists and is directly computable via maximum likelihood routines. As a result, our asymptotic results remain valid even in regions where existing maximum likelihood results are not obtainable, with no overhead in implementation or computation. The dependency of the estimators on the prior hyper-parameter facilitates the derivation of estimators with zero asymptotic bias and minimal mean squared error. We will explore these estimators' shrinkage properties, substantiate our theoretical findings with simulations and applications.

Seminario Padova - Carlos Escudero Lienana

19 Mar '24

Buongiorno a tutti, Vorremmo segnalarvi che venerdì prossimo (22 Marzo) alle ore 14:30 in aula 2AB40 (Torre Archimede, Università di Padova) ci sarà un seminario per il ciclo di seminari in Probabilità e Finanza di: Carlos Escudero Lienana (Universidad Autónoma de Madrid) <https://portalcientifico.uned.es/investigadores/204034/colaboracion/organiz aciones/9> https://portalcientifico.uned.es/investigadores/204034/colaboracion/organiza ciones/9 Title: The noise interpretation problem in mathematical physics Date: March 22, 2024, at 14:30 room 2AB40 Abstract: Stochastic differential equations have been used as models in physics and finance for many decades now. Before a rigorous theory of these mathematical objects were introduced, and even after that, an informal use of these equations has been employed in these two fields, among many others. Herein we will focus on the extensive use of them employed in statistical physics. While the primordial use is explicitly informal, at some point the physics community recognize the importance of using a more precise language. This is the starting point of the noise interpretation problem, which translated, in hundreds of papers, in deciding whether a given model should be considered an Itô or a Stratonovich stochastic integral equation. Quite surprisingly, after several decades and hundreds of papers, and also after the question was considered settled by a certain establishment, the problem still seems to be open. Herein we will show certain examples that illustrate how this search for a more precise language in the physics literature has translated old ambiguities into newer ones. We will resolve some of them using the precise mathematical language introduced by Kiyoshi Itô and other classical stochastic analysts. Vi aspettiamo numerosi!

Seminari PRISMA - lun 8 aprile 2024
by Francesco Caravenna 19 Mar '24

19 Mar '24

Seminari on-line del gruppo UMI - PRISMA (http://www.umi-prisma.polito.it/ <http://www.umi-prisma.polito.it/>) I seminari PRISMA hanno un formato di "colloquium" per creare un'occasione di scambio e discussione con tutta la comunità dei probabilisti e statistici italiani. Ogni giornata comprende due relatori che tengono due seminari di 30 minuti strettamente connessi, per presentare alla comunità una prospettiva sul proprio ambito di ricerca. Da quest'anno le registrazioni dei seminari vengono pubblicate sul canale YouTube dell'UMI: https://www.youtube.com/@umi1922/videos <https://www.youtube.com/@umi1922/videos> Il prossimo appuntamento è per lunedì 8 aprile 2024. I relatori saranno Emanuela Sasso (Università di Genova) e Federico Girotti (Politecnico di Milano) che parleranno di Semigruppi quantistici markoviani: decoerenza, ricorrenza e accessibilità con il seguente orario: 16:00 Primo seminario 16:30 Pausa e discussione 16:45 Secondo seminario 17:15 Conclusione e discussione Trovate di seguito il riassunto. I seminari verranno trasmessi via Zoom al seguente link: https://uniroma1.zoom.us/j/82939128330 <https://uniroma1.zoom.us/j/82939128330> Meeting ID: 829 3912 8330 Vi aspettiamo numerosi! Valentina Cammarota e Francesco Caravenna %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Emanuela Sasso (Università di Genova) e Federico Girotti (Politecnico di Milano) TITOLO: Semigruppi quantistici markoviani: decoerenza, ricorrenza e accessibilità RIASSUNTO: I semigruppi markoviani quantistici sono essenzialmente semigruppi di operatori positivi su algebre di operatori con le opportune proprietà di continuità e che rafforzano la positività. Appaiono nella letteratura fisica e fisico-matematica alla fine degli anni '60 con il nome di semigruppi dinamici quantistici nella modellizzazione e nell'analisi dei sistemi aperti in meccanica quantistica. Tuttavia, dal punto di vista matematico, costituiscono la naturale generalizzazione dei semigruppi markoviani classici, infatti questi ultimi sono semigruppi di operatori definiti su un'algebra di funzioni, cioè un'algebra di operatori che commutano tra loro. Il modo più naturale per descrivere un sistema quantistico è un’algebra di Von Neumann e la sua evoluzione come una famiglia di operatori debole*-continui, che formino un semigruppo e che abbiano la proprietà di markovianità. Se il sistema è chiuso allora la sua evoluzione è reversibile, altrimenti se interagisce con l’ambiente allora ci potrebbe essere una parte diffusiva. In Fisica, si parla di “decoerenza” quando solo una parte del sistema evolve in maniera automorfica (l’algebra priva di decoerenza, appunto) e una parte “scompare” per tempi lunghi. La nostra ricerca si è focalizzata a lungo su quale definizione di decoerenza sia più adatta e se è possibile trovare condizioni necessarie e sufficienti per il suo verificarsi. Nello studio dei processi (semigruppi) di Markov classici sono fondamentali le nozioni di ricorrenza e comunicazione tra insiemi di stati; mostreremo come questi concetti siano stati generalizzati nel caso noncommutativo e discuteremo alcune delle loro proprietà e relazioni. Particolare attenzione sarà dato al caso in cui l’algebra su cui agisce il semigruppo sia l’insieme di tutti gli operatori lineari limitati che agiscono su uno spazio di Hilbert. %%%%%%%%%%%%%%%%%%%%%%%%%%%%

SPASS seminar: Patrick Charbonneau
by Andrea Agazzi 15 Mar '24

15 Mar '24

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi: *Toward a robust definition of random close packing* by Patrick Charbonneau (Duke University) The seminar will take place on TUE, 19.03.2024 at 14:30 CET (*please note the unusual time*) in Aula Seminari, Dipartimento di Matematica, UNIPI and streamed online at this link <https://meet.google.com/gji-phwo-vbg>. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass -------------------------------------------- *Abstract: **The apparent simplicity of amorphous sphere packings can be misleading. Although jamming hard spheres to random close packing (rcp) has been studied for decades, an unambiguous definition of rcp, let alone a first-principle prediction remain elusive. Drawing inspiration from liquid state theory, rcp can be identified with the inherent structure of a hard sphere liquid. Identifying inherent structures of hard spheres through optimization, however, is a non-trivial problem. Motivated by a recent (meta-)analysis of existing algorithms, we consider the behavior of minimal models of jamming that can be studied using various approaches, notably with tools from stochastic geometry and the mean-field description of simple glasses. The resulting insights present a path toward formalizing rcp.*
