Seminari on-line del gruppo UMI - PRISMA (http://www.umi-prisma.polito.it/ <http://www.umi-prisma.polito.it/>) Ricordiamo che oggi, giovedì 7 marzo 2024, Luca Avena (Università di Firenze) e Matteo Quattropani (Sapienza Università di Roma) parleranno di Incontri tra passeggiate aleatorie e dinamiche di opinione su grafi random 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: Luca Avena (Università di Firenze) e Matteo Quattropani (Sapienza Università di Roma) TITOLO: Incontri tra passeggiate aleatorie e dinamiche di opinione su grafi random RIASSUNTO: Nella prima parte del seminario discuteremo risultati, classici o più recenti, della teoria che lega il comportamento di passeggiate aleatorie su grafi finiti a quello dei processi di coalescenza, e le relative implicazioni nell’analisi del tempo di consenso per dinamiche di opinione markoviane. Nella seconda parte del seminario presenteremo uno specifico risultato, ottenuto recentemente in collaborazione con Federico Capannoli e Rajat Shubra Hazra (Leiden University), in cui il grafo sottostante è aleatorio, orientato, e con un arbitraria sequenza di gradi. In particolare, in funzione della sequenza dei gradi scelta, identificheremo esplicitamente la legge dei tempi di incontro di due passeggiate aleatorie e, di conseguenza, il tempo di consenso per la dinamica di opinione associata. Discuteremo quindi delle implicazioni di questo risultato nel contesto applicativo del design delle reti, individuando le caratteristiche del grafo che tendono ad aumentare o a diminuire il tempo necessario a raggiungere il consenso. %%%%%%%%%%%%%%%%%%%%%%%%%%%% 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 %%%%%%%%%%%%%%%%%%%%%%%%%%%%

Seminario Andrea Di Primio - Politecnico di Milano - 6 Marzo 2024
by Luca Scarpa 05 Mar '24

05 Mar '24

Si segnala il seguente seminario a tutti gli interessati. Mercoledì 6 Marzo 2024, ore 11:30. Aula Seminari III Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Andrea Di Primio. Title: Stochastic diffuse interface models with conservative noise. Abstract: Cahn-Hilliard type models are widely used to model phase separation phenomena occurring in multicomponent systems subject to thermodynamical stress. In 1970, a stochastic variant taking into account thermal effects driving spinodal decomposition was proposed by H. Cook. This model generalizes its deterministic counterpart and better fits available experimental data, especially in the early stages of phase separation. In this talk, I will examine the stochastic analysis of an almost-surely mass-conserving stochastic Cahn-Hilliard model, which stems from the original Cahn-Hilliard-Cook model when endowed with a conservative noise in divergence form. The mass conservation property is indeed expected in the deterministic version of the system. Our first-step investigation concerns the existence of unique probabilistically strong solutions to the equation, appealing to stochastic variational techniques. Some insights on the corresponding Allen-Cahn relaxation, for which we show conditional results, will also be given. In all models, a thermodynamical singular potential is considered. Further open questions will also be presented.

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 8 Marzo 2024, alle ore 12.00, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Speaker: Jaromir Sant (University of Oxford UK) Title: *Inferring natural selection and allele age from allele frequency time series data via exact simulation* Abstract: A standard problem in population genetics is that of inferring evolutionary and biological parameters such as the strength of natural selection and allele age from DNA samples. Up until recently, most of the datasets available for such a task were obtained by sampling individuals from a contemporaneous population simultaneously, thereby offering a static snapshot of the population’s genetic diversity. However, recent advances in DNA extraction and sequencing technologies have allowed for ancient DNA found at archaeological sites to be analysed, leading to the creation of several time-series datasets detailing historical changes in allele frequencies. These datasets have paved the way for the development of powerful inferential techniques which explicitly exploit this new temporal dependence in the data to provide better estimators. In this talk I shall introduce a Markov Chain Monte Carlo framework which allows for inferring selection and allele age based on time-series data coming from an underlying Wright-Fisher diffusion. The chief novelty is that by augmenting the state space with the unobserved diffusion trajectory we are able to develop an efficient method in which trajectory updates and accept/reject probabilities can be calculated without error, in spite of the diffusion’s intractable transition density. We illustrate the method’s performance on simulated data, and subsequently apply it to an ancient DNA horse dataset. This is joint work with Paul Jenkins (Warwick), Jere Koskela (Newcastle), and Dario Spanò (Warwick). ------------------------------------------------ Sarà possibile seguire il seminario anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/87097731960?pwd=TjZ3YlNEbjFYeW9sUkl6OXN2SDB1QT09> 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/>

IEEE MetroLivEnv 2024 - Special Session PROBABILITY AND MATHEMATICAL STATISTICS FOR LIVING ENVIRONMENT AND METROLOGY
by Antonella Iuliano 03 Mar '24

03 Mar '24

Dear Colleagues, we would like to draw your attention to the upcoming 2024 IEEE INTERNATIONAL WORKSHOP ON METROLOGY FOR LIVING ENVIRONMENT that will be held at Chania, Crete, GREECE, June 12-14, 2024. The following Special Session is open to receive your submissions. PROBABILITY AND MATHEMATICAL STATISTICS FOR LIVING ENVIRONMENT AND METROLOGY Probability Theory and Statistics provide powerful tools for the development of new mathematical models to describe real life phenomena. In particular, the use of metrology refers to living environment plays an important role in many applicative fields to understand and identify sources of variability and to minimise their influence. The aim of this section is to cover the lack of probabilistic and machine learning approaches in this area. In fact, one of the most significant advantages using probabilistic models is to gain a comprehensive view of the uncertainty associated with a measurement result. A special attention will be give to results related to the quality of the living environment as a direct impact on human health and well-being. Website: https://www.metrolivenv.org/special-session-2 The deadline for Extended Abstract Submissions is March 10, 2024. https://www.metrolivenv.org/call-for-papers For further information and updates please visit the conference website: https://www.metrolivenv.org/index.php/ We are looking forward to Welcome you in Chania!

International Conference in Venice - CALL FOR PAPERS
by Monica Billio 02 Mar '24

02 Mar '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-thrid* 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 *May 31, 2023 *to the address given below (preferably in electronic format). Please indicate to whom correspondence should be addressed. Decisions regarding acceptance will be made by *June 30, 2023*. The final version of accepted papers must be received by August 31, 2023.

Seminar: Alessandra Menafoglio March 12, 2024, Ca' Foscari University of Venice
by Carlo Gaetan 29 Feb '24

29 Feb '24

Dear all, we are glad to announce the following hybrid seminar *March 12, 2024, 12:15 PM* *Where*: Aula Delta 2C- edificio Zeta (Campus Scientifico), Via Torino, 155 Mestre (Venice, Italy) Zoom: https://unive.zoom.us/j/85153268624?pwd=MzBhdlA2M1B2dThJQ2Y5T0EwUE5PZz09 *Speaker*: Alessandra Menafoglio, Politecnico di Milano (Milano, Italy) *Title*: The Bayes space approach to functional data analysis for probability density functions *Abstract:* In the presence of increasingly massive and heterogeneous data, the statistical modeling of distributional observations plays a key role. Choosing the ‘right’ embedding space for these data is of paramount importance for their statistical processing, to account for their nature and inherent constraints. The Bayes space theory is a natural embedding space for (spatial) distributional data, and was successfully applied in varied settings. In this presentation, I will discuss the state-of-the-art methods for the modelling, analysis, and prediction of distributional data, with a particular attention to cases when their spatial dependence cannot be neglected. I will embrace the viewpoint of object-oriented spatial statistics (O2S2), a system of ideas for the analysis of complex data with spatial dependence. All the theoretical developments will be illustrated through their application on real data, highlighting the intrinsic challenges of a statistical analysis which follows the Bayes spaces approach.

1 Year Post-Doc position in Verona
by Alessandro Gnoatto 29 Feb '24

29 Feb '24

1 Year Post-Doc position in Verona I am looking for a post-doc to join my group. The topic of the research project is "Machine learning and stochastic control for financial risk management" The aim of this project is to study new methods, models, and numerical techniques for the treatment of financial risk management problems, in particular counterparty credit risk (xVA) or the pricing of financial and insurance claims. Many problems in finance involve the minimization of a cost functional subject to controlled stochastic state variables. Controls or related quantities in high dimension can be conveniently approximated by means of artificial neural networks. The aim of the project is to study control problems and partial (integro) differential equations under general dynamics together with the development of new models for the evolution of risk factors, with a special focus on interest rates. The candidate should have a solid background in probability, stochastic calculus and computational finance. Experience with the Java and/or Python programming languages and Machine Learning frameworks such as Tensorflow, Deep Java Library or Deeplearning4J is a plus. Candidates will be evaluated based on their scientific quality and their potential in developing research. There are no teaching obligations and knowledge of Italian is not required. The deadline for applications is the 19 March 2024 (h. 13.00). The link to the call is here https://docs.univr.it/documenti/Concorso/bando/bando371360.pdf The call is in Italian. Non-Italian speakers needing help with the form can contact me at alessandro [dot] gnoatto [at] univr [dot] it I am happy to help.

Seminario Ilya Losev - Lunedì 4 Marzo - Sapienza Università di Roma
by Silvestri, Vittoria 26 Feb '24

26 Feb '24

Si segnala il seguente seminario: Lunedì 4 Marzo 2024, ore 16:00, Sala di Consiglio, Dipartimento di Matematica "Guido Castelnuovo", Sapienza Università di Roma. *Speaker: *Ilya Losev (University of Cambridge, UK) *Title: *How long are the arms in Dielectric-Breakdown Model? *Abstract: *In this talk we will discuss the recent progress on such random growth models as Diffusion Limited Aggregation (DLA) and Dielectric-Breakdown Model (DBM) in 2 and 3 dimensions. These models are believed to exhibit non-equilibrium growth, producing irregular fractal patterns. The main questions about these processes include finding their scaling limits and fractal dimensions. However, almost nothing is known rigorously. The main result about these models is due to Kesten, who gave a non-trivial lower bound on the fractal dimension of DLA clusters. The main tool in his proof was the famous Beurling’s estimate. We generalize this result to DBM and give a new proof of Kesten’s Theorem. Our proof does not rely on Beurling’s estimate. Instead, we exploit the connection between DBM growth properties and multifractal spectrum of the harmonic measure. ******************************** Vittoria Silvestri Assistant Professor Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome ********************************

ABS24 school "Bayesian Phylogenetics and Infectious Diseases" in Como, Italy (August 26-30, 2024) - Registration are open
by Elisa Varini 26 Feb '24

26 Feb '24

Dear all, We are glad to inform you that the next Applied Bayesian Statistics school - ABS24 will be held in the city of Como, along the Lake Como shoreline, on August 26-30, 2024. The school is organised by CNR IMATI (Institute of Applied Mathematics and Information Technologies at the National Research Council of Italy in Milano), in cooperation with Fondazione Alessandro Volta. The topic will be BAYESIAN PHYLOGENETICS AND INFECTIOUS DISEASES. The lecturer will be Prof. MARC SUCHARD (Department of Biostatistics, UCLA Fielding School of Public Health, USA), with the support of Filippo Monti (PhD student in Biostatistics, UCLA, USA). If interested, you can register on the school website: https://abs24.imati.cnr.it/ If you are interested in the school but unwilling to register for the moment, please send an email to abs24(a)mi.imati.cnr.it and we will send you updates and reminders. As in the past (since 2004), there will be a combination of theoretical and practical sessions, along with presentations by participants about their work (past, current and future) related to the topic of the school. OUTLINE: The aim of this course is to explore the core challenges of Bayesian inference of stochastic processes in modern biology in terms of data-scale, model-dimensionality and compute-complexity. Challenging and emerging statistical solutions will be illustrated through the analysis of biological sequences, such as genes and genomes. Molecular phylogenetics has become an essential analytical tool for understanding the complex patterns in which rapidly evolving pathogens propagate across and between countries, owing to the complex travel and transportation patterns evinced by modern economies, along with growing political factors such as increased global population and urbanisation. As an accessible course for all, a brief introduction of the underlying biology (for statistical researchers) and of modern Bayesian inference (for practicing biologists) will be also provided. Topics will cover probabilistic modeling techniques using both discrete- and continuous-valued stochastic processes including continuous-time Markov chains and Gaussian processes; large-scale data-integration approaches incorporating factors like human mobility and climate measurements; recursive computing and other mathematical tricks to evaluate seemingly intractable likelihoods; state-of-the-art sampling methods for high-dimensional models including Hamiltonian Monte Carlo and its more recent non-reversible extensions; delivering timely inference on advancing computing hardware like graphics processing units and (maybe even) quantum devices. We hope you will be interested in the school and we would like to meet you in Como next year. We invite you also to share the information with people potentially interested. Best regards Elisa Varini and Fabrizio Ruggeri Executive Director and Director of ABS24

[please distribute - apologies for multiple postings] Dear Colleagues, the SMPS 2024 conference (Soft Methods in Probability and Statistics) will take place on September 03-06, 2024, in Salzburg, Austria. We expect 80-120 participants and - apart from an interesting scientific event - also plan to integrate in the conference what Salzburg is most famous for: classical music and beautiful landscapes. Our objective is to keep the fees including lunches, conference dinner, social events and Springer book of proceedings low (300-400€ regular price, reduced amount of 150-180€ for PhD students; precise numbers to be determined in spring after knowing the exact number of participants). Confirmed plenary spearkers are: Siegfried Hörmann (Graz University of Technology, AT) Susanne Saminger-Platz (Johannes Kepler University Linz, AT) Steven Vanduffel (Vrije Universiteit Brussel, BE) Ingrid Van Keilegom (KU Leuven, BE) Christian Wagner (University of Nottingham, UK) The SMPS conference series has the tradition to collect short papers of 6-8 pages of all participants giving a talk - these papers will undergo a quick peer-review and should either contain novel results or provide a survey over recently established material. All accepted contributions will be published in a Springer conference proceedings book with the title "Combining, modelling and analyzing imprecision, randomness and dependence". Elsevier will sponsor SMPS 2024 with a best paper award of 1000€, additionally there will be a special issue related to the conference in the International Journal of Approximate Reasoning. Submission of short papers will be possible as of January 1st, 2024, and ends on March 17th, 2024. Required LaTex style etc., a link to the submission platform, and additional information can be found on the conference homepage http://www.smps2024.com <https://eur05.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.smps20…>.

Sapienza seminar in Probability and Statistics - Refik Soyer
by Luisa Beghin 23 Feb '24

23 Feb '24

Dear all, We would like to invite you to the following talk: *Thursday 29th February at 1**5:00* Room 24 (fourth floor), Dipartimento di Scienze Statistiche (Ed. CU002), Sapienza University *Speaker: Refik Soyer* (George Washington University (US)) *Title: Latent Factor Multivariate Integer-Valued AR Processes* Abstract: We introduce a new class of multivariate integer-valued autoregressive (INAR) models based on the notion of a common random environment. Dependence among the components of the multivariate time series is induced via the common environment that follows a Markovian evolution. The proposed framework provides us with a dynamic multivariate generalization of the univariate INAR processes. We develop a Markov chain Monte Carlo method as well as a particle learning algorithm for Bayesian inference. We consider an extension of the model to handle zero inflated time-series data and illustrate the proposed class of models using actual multivariate count data and discuss their predictive performance.

Fwd: SPASS Seminar: Matteo Sfragara
by Gianmarco Bet 21 Feb '24

21 Feb '24

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi: Chaos and concentration in spatial growth models by Matteo Sfragara (Stockholm University) The seminar will take place on TUE, 27.02.2024 at 14:00 CET in Aula Tricerri, Dipartimento di Matematica e Informatica "Ulisse Dini", UNIFI and streamed online at the link which you can find in the seminar website below. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass <https://sites.google.com/unipi.it/spass> -------------------------------------------- Abstract: A decade and a half ago Chatterjee established the first rigorous connection between anomalous fluctuations (superconcentration) and a chaotic behaviour of the ground state in certain Gaussian disordered systems. We study the connection between chaos and concentration in spatial growth models, like first-passage percolation (FPP) and last-passage percolation (LPP), and we prove that they exhibit a chaotic behaviour. This extends previous work on the topic, and illustrates that this is a phenomenon that can be expected more widely. The notion of ‘chaos' refers to the sensitivity of the optimal path (geodesic) when exposed to a slight perturbation. In FPP on Z^d the geodesic is the time-minimizing path from the origin to a vertex v, while in LPP on the square lattice [0,n]^2 the geodesic is the weight-maximizing up-right path from (0,0) to (n,n). This talk is based on two joint works with Daniel Ahlberg and Mia Deijfen (Stockholm University).

Seminar: Federico Ferraccioli February 27, 2024, Ca' Foscari University of Venice

Dear all, we are glad to announce the following hybrid seminar *February 27, 2024, 12:15 PM* *Where*: Sala Riunioni B - edificio Zeta (Campus Scientifico), Via Torino, 155 Mestre (Venice, Italy) Zoom:https://unive.zoom.us/j/85153268624?pwd=MzBhdlA2M1B2dThJQ2Y5T0EwUE5PZz09 *Speaker*: Federico Ferraccioli, Università degli Studi di Padova *Title*: Detecting stable modes using stochastic gradients *Abstract:* In the framework of density based clustering, modes represent a crucial concept as they identify high-density regions that can be associated to different groups of observations. The possibility to conduct inference on the resulting clusters remains nonetheless an intriguing yet quite intricate problem. To tackle this challenge, we propose a procedure that leverages on the connection between mean-shift clustering and stochastic gradient methods. This enables the definition of a sampling procedure, which can be used to construct confidence regions for the modes of a density. We investigate the asymptotic properties of the proposed method and evaluate its performances across different scenarios.

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/watch?v=5puCfBWCdRA> Il prossimo appuntamento è per giovedì 7 marzo 2024. I relatori saranno Luca Avena (Università di Firenze) e Matteo Quattropani (Sapienza Università di Roma) che parleranno di Incontri tra passeggiate aleatorie e dinamiche di opinione su grafi random 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: Luca Avena (Università di Firenze) e Matteo Quattropani (Sapienza Università di Roma) TITOLO: Incontri tra passeggiate aleatorie e dinamiche di opinione su grafi random RIASSUNTO: Nella prima parte del seminario discuteremo risultati, classici o più recenti, della teoria che lega il comportamento di passeggiate aleatorie su grafi finiti a quello dei processi di coalescenza, e le relative implicazioni nell’analisi del tempo di consenso per dinamiche di opinione markoviane. Nella seconda parte del seminario presenteremo uno specifico risultato, ottenuto recentemente in collaborazione con Federico Capannoli e Rajat Shubra Hazra (Leiden University), in cui il grafo sottostante è aleatorio, orientato, e con un arbitraria sequenza di gradi. In particolare, in funzione della sequenza dei gradi scelta, identificheremo esplicitamente la legge dei tempi di incontro di due passeggiate aleatorie e, di conseguenza, il tempo di consenso per la dinamica di opinione associata. Discuteremo quindi delle implicazioni di questo risultato nel contesto applicativo del design delle reti, individuando le caratteristiche del grafo che tendono ad aumentare o a diminuire il tempo necessario a raggiungere il consenso. %%%%%%%%%%%%%%%%%%%%%%%%%%%%

SPASS Seminar: Leonardo Tolomeo
by Francesco Grotto 14 Feb '24

14 Feb '24

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi: *Transport of Gaussian measures under the flow of Hamiltonian PDEs: quasi-invariance and singularity* by Leonardo Tolomeo (University of Edinburgh) The seminar will take place on TUE, 20.02.2024 at 14:00 CET in Aula Seminari, Dipartimento di Matematica, UNIPI and streamed online at the link below. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass -------------------------------------------- *Abstract: In this talk, we consider the Cauchy problem for the fractional NLS with cubic nonlinearity (FNLS), posed on the one-dimensional torus T, subject to initial data distributed according to a family of Gaussian measures. * *We first discuss how the flow of Hamiltonian equations transports these Gaussian measures. When the transported measure is absolutely continuous with respect to the initial measure, we say that the initial measure is quasi-invariant. * *In the high-dispersion regime, we exploit quasi-invariance to build a (unique) global flow for initial data with negative regularity, in a regime that cannot be replicated by the deterministic (pathwise) theory. * *In the 0-dispersion regime, we discuss the limits of this approach, and exhibit a sharp transition from quasi-invariance to singularity, depending on the regularity of the initial measure. * *This is based on joint works with J. Forlano (UCLA/University of Edinburgh) and with J. Coe (University of Edinburgh).*

Seminario di Giuseppe Cannizzaro - Lunedì 19 Febbraio - Sapienza Università di Roma
by Silvestri, Vittoria 14 Feb '24

14 Feb '24

Si segnala il seguente seminario: Lunedì 19 Febbraio 2024, ore 16:00, Sala di Consiglio, Dipartimento di Matematica "Guido Castelnuovo", Sapienza Università di Roma *Speaker: *Giuseppe Cannizzaro (University of Warwick, UK) *Title: *Weak coupling scaling of critical SPDEs *Abstract: *The study of stochastic PDEs has known tremendous advances in recent years and, thanks to Hairer's theory of regularity structures and Gubinelli and Perkowski's paracontrolled approach, (local) existence and uniqueness of solutions of *subcritical* SPDEs is by now well-understood. The goal of this talk is to move beyond the aforementioned theories and present novel tools to derive the scaling limit (in the so-called weak coupling scaling) for some stationary SPDEs at the *critical* dimension. Our techniques are inspired by the resolvent method developed by Landim, Olla, Yau, Varadhan, and many others, in the context of particle systems in the *supercritical* dimension. Time allowing, we will explain how it is possible to use our techniques to study a much wider class of statistical mechanics models at criticality such as (self-)interacting diffusions in random environment. ******************************** Vittoria Silvestri Assistant Professor Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome ********************************

Winter mini-course on machine learning at Tor Vergata
by Michele Salvi 13 Feb '24

13 Feb '24

Dear all, Also this Winter RoMaDS ( https://www.mat.uniroma2.it/~rds/events.php ) will offer a mini-course on the mathematics of machine learning at Tor Vergata University in Rome. This year we are very happy to host Giovanni Conforti (Università di Padova & École Polytechnique, Paris) and Alain Durmus (École Polytechnique, Paris) from the 19th to the 22nd of February. They will present a 9 hours mini-course titled An introduction to Score-based Generative Models The course will be addressed also to non-experts of the field, it will be divided in 3 slots of 3 hours each and the tentative program is as follows (see the whole abstract at the end of the email): Lecture 1 & Lecture 2. (Mon 19th, 14h00-17h00) Introduction to generative models & Probabilistic/statistical tools for generative models Lecture 3 & Lecture 4. (Wed 21st, 09h30-12h30) A ”discrete” introduction to score-based diffusion models & A Itô-diffusion viewpoint on score-based diffusion models. Lecture 5 & Lecture 6. (Thu 22nd, 09h30-12h30) Convergence bounds for score-based diffusion models via stochastic control & Optimal transport and entropic optimal transport for generative modeling. You can find the whole Syllabus with more details on each lecture on RoMaDS webpage: https://www.mat.uniroma2.it/~rds/Files/SyllabusSGM.pdf All the lectures will be held in Aula Dal Passo, Department of Mathematics - Tor Vergata University. We do encourage in-person participation. Should you unable to come, here is the link to the event on Teams: https://teams.microsoft.com/l/meetup-join/19%3arfsL73KX-fw86y1YnXq2nk5VnZFw… The seminar is part of the Excellence Project MatMod@TOV. Best, Michele Salvi Abstract of the course “An introduction to Score-based Generative Models” In simple words, generative modeling consists in learning a map capable of generating new data instances that resemble a given set of observations, starting from a simple prior distribution, most often a standard Gaussian distribution. This course aims at providing a mathematical introduction to generative models and in particular to Score-based Generative Models (SGM). SGMs have gained prominence for their ability to generate realistic data across diverse domains, making them a popular tool for researchers and practitioners in machine learning. Participants will learn about the methodological and theoretical foundations, as well as some practical applications associated with these models. The first two lectures motivate the use of generative models, introduce their formalism and present two simple though relevant examples: energy-based models and Generative Adversarial Networks. In the third and fourth lecture we present score-based diffusion models and explain how they provide an algorithmical framework to the basic idea that sampling from the time-reversal of a diffusion process converts noise into new data instances. We shall do so following two different approaches: a first elementary one that only relies on discrete transition probabilities, and a second one based on stochastic calculus. After this introduction, we derive sharp theoretical guarantees of convergence for score-based diffusion models assembling together ideas coming from stochastic control, functional inequalities and regularity theory for HamiltonJacobi-Bellman equations. The course ends with an overview of some of the most recent and sophisticated algorithms such as flow matching and diffusion Schrödinger bridges (DSB), which bring an (entropic) optimal transport insight into generative modeling.

It finds applications in (Euclidean) quantum field theory, being related to the solutions of the equations of motion for the correlation functions of the quantum field. We approach this problem in the particular case of quantum field theory with exponential interaction on $\mathbb{R}^2$, studying a Fokker-Planck-Kolmogorov equation associated to a stochastic quantization equation for such a model. We prove that, under some conditions on the support of the measure, the solution to this Fokker-Planck-Kolmogorov equation exists and is unique, providing a complete characterization of the exponential measure by an integration by parts formula. The talk is based on a joint work with Massimiliano Gubinelli and Mattia Turra. *Referente*: Sonia Mazzucchi Per conoscere i prossimi eventi è possibile consultare la pagina *https://webmagazine.unitn.it/ciclo/dmath/118024/trento-probability-seminars-20232024 <https://webmagazine.unitn.it/ciclo/dmath/118024/trento-probability-seminars…>* Gli eventi passati si trovano alla pagina *https://webmagazine.unitn.it/ciclo/dmath/114273/trento-probability-seminars-20222023 <https://webmagazine.unitn.it/ciclo/dmath/114273/trento-probability-seminars…>* [image: Università di Trento] <http://www.unitn.it/> *Staff di Dipartimento-Matematica* Università degli Studi di Trento Via Sommarive, 14 - 38123 Povo (TN) Tel. +39 0461 283898 - Francesca Stanca Tel. +39 0461 281980 - Michela Vinotti Tel. +39 0461 281625 - Orietta Osele Tel. +39 0461 281701 - Cinzia Parolari -- Dr. Michele Coghi University of Trento, Math Department via Sommarive 14 - 38123 Povo (Trento) - I Povo 0, Room 2.91 E-Mail: michele.coghi(a)unitn.it

Seminario di Alexandre Stauffer - 12 Febbraio - Sapienza Università di Roma
by Lorenzo Taggi 06 Feb '24

06 Feb '24

Lunedì 12 Febbraio 2024, ore 16:00, Sala di Consiglio, Dipartimento di Matematica "Guido Castelnuovo", Sapienza Università di Roma *Speaker:* Alexandre Stauffer (King's College London and University of Bath) *Titolo:* Mixing time of random walk on dynamical random cluster *Abstract:* We consider a random walk jumping on a dynamic graph; that is, a graph that changes at the same time as the walker moves. Previous works considered the case where the graph changes via dynamical percolation, in which the edges of the graph switch between two states, open and closed, and the walker is only allowed to cross open edges. In dynamical percolation, edges change their state independently of one another. In this work, we consider a graph dynamics with unbounded dependences: Glauber dynamics on the random cluster model. We derive tight bounds on the mixing time when the density of open edges is small enough. For the proof, we construct a non-Markovian coupling using a multiscale analysis of the environment. This is based on joint work with Andrea Lelli.

Reminder: de Finetti seminar February 7
by Marco Maggis 05 Feb '24

05 Feb '24

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: Giorgio Ferrari Bielefeld University Title: Stationary Mean-field Games with Singular Controls Abstract: In this talk I will present recent and ongoing results on existence, uniqueness, and characterization of equilibria for mean-field games with singular controls. This class of problems finds natural applications in Economics and Finance, such as in investment problems in oligopolies. In those games, the representative agent employs a bounded-variation control in order to maximize an ergodic profit functional depending on a long-time average of the controlled state-process.
