LTI@UniTO seminars | Christopher Polk, May 2nd and Andrea Tamoni, May 3rd @12.00
by Luca Regis 24 Jun '23

24 Jun '23

Dear Colleagues, it is my pleasure to invite you to the following two seminars in Quantitative Finance, organised by LTI@UniTO (www.carloalberto.org/lti) and Collegio Carlo Alberto (CCA), which will take place at CCA in Torino and can be followed via Zoom. At the event page link you can find the paper, the zoom link to attend online and a button to add the event to your calendars. ------------------------------------------------------------------------------------------- May 2nd @ 12.00 Speaker: Christopher Polk (LSE) Title: The Day Destroys the Night, Night Extends the Day: A Clientele Perspective on Equity Premium Variation Abstract: We decompose market returns into their overnight and intraday components, which dramatically improves equity premium forecasts. Past smoothed overnight market returns strongly negatively forecast subsequent close-to-close returns (quarterly R2 of over 14%), primarily through intraday mean reversion. In contrast, past smoothed intraday market returns strongly positively forecast subsequent overnight returns; this partially-offsetting effect explains PE’s relatively poor forecasting ability (R2 only 3%). Our decomposition also resurrects the conditional CAPM: If we allow market betas to vary with past smoothed overnight returns, the four Fama-French factors’ alphas decrease on average by 84%. We interpret these return patterns through a clientele perspective. First, individual investor expectations and consumption growth strongly positively forecast overnight market returns, while intermediary risk tolerance strongly negatively forecasts intraday market returns. Second, aggregate cash-flow news occurs primarily intraday and is positively (negatively) correlated with revisions in expected future overnight (intraday) returns. Finally, while the Tech boom, Covid crash/rebound, and patterns in meme stocks were primarily driven by overnight returns, the Global Financial Crisis was mostly an intraday phenomenon. Event webpage link: https://www.carloalberto.org/event/christopher-polk-london-school-of-econom… Zoom link: https://us02web.zoom.us/j/83709123462pwd=OWpUM0VvRVNzbTN0bUJlRVVsNzA4Zz09 ------------------------------------------------------------------------------------------------------------------------------ May 3rd @ 12.00 Speaker: Andrea Tamoni (Rutgers Business School) Title: Stock Demand and Price Impact of 401(k) Plans Abstract: We estimate a demand system linking 401(k) plans ownership of individual stocks and funds to their demand for equities, and quantify the effect of 401(k) assets on fund managers’ investment behavior. We find that 401(k) fund and stock ownership are the most important variables, after size, explaining fund demand for stocks, with a one standard deviation increase in 401(k) ownership leading to 15-30% increase in stock demand. Funds managing a larger fraction of 401(k) assets tilt their portfolios toward winners, high beta and long duration stocks, outperforming their benchmarks. This investment behavior has important implications for security pricing and generate a feedback effect if pension flows respond positively to relative fund returns. Lastly, we estimate the equilibrium price impact of a change in 401(k) ownership to be positive and increasing over time, consistent with the shift from active to passive investing.

Seminar by Katia Colaneri in Milan (25.01.23)
by Valeria Bignozzi 23 May '23

23 May '23

Dear all, you're invited to the seminar that will take place, in hybrid mode, at the Department of Statistics and Quantitative Methods, University of Milano-Bicocca. More details: • Speaker: Katia Colaneri (email: katia.colaneri(a)uniroma2.it <mailto:katia.colaneri@uniroma2.it>) Title: Some Optimisation Problems in Insurance with a Terminal Distribution Constraint Abstract: In this paper, we study two optimisation settings for an insurance company, under the constraint that the terminal surplus at a deterministic and finite time T follows a normal distribution with a given mean and a given variance. In both cases, the surplus of the insurance company is assumed to follow a Brownian motion with drift. First, we allow the insurance company to pay dividends and seek to maximise the expected discounted dividend payments or to minimise the ruin probability under the terminal distribution constraint. Here, we find explicit expressions for the optimal strategies in both cases, when the dividend strategy is updated at discrete points in time and continuously in time. Second, we let the insurance company buy a reinsurance contract for a pool of insured or a branch of business. We only allow for piecewise constant reinsurance strategies producing a normally distributed terminal surplus, whose mean and variance lead to a given Value at Risk or Expected Shortfall at some confidence level α. We investigate the question which admissible reinsurance strategy produces a smaller ruin probability, if the ruin-checks are due at discrete deterministic points in time. This presentation is based on a joint work with Julia Eisenberg (TU Vienna) and Benedetta Salterini (University of Firenze) Seminar venue: University of Milano-Bicocca Department of Statistics and Quantitative Methods Aula Seminari 4026, 4th floor, Building U7 January 25th, 4:30 pm Webex Link : https://unimib.webex.com/unimib/j.php?MTID=m40cd4bb0d7bb8035ca68f3821f453b33 <https://unimib.webex.com/unimib/j.php?MTID=m40cd4bb0d7bb8035ca68f3821f453b33> Join by meeting number Meeting number (access code): 2743 983 3965 Meeting password: c2uJfPBVe83 (22853728 from phones) Best regards, Valeria

(PMS)^2 talk: J.-D. Deuschel [4 May] at UniMIB
by Maurizia Rossi 03 May '23

03 May '23

Dear colleagues, We are happy to announce the following *hybrid* - that is, in person with online streaming - talk: Speaker: *Jean-Dominique Deuschel* (TU Berlin) *Title: *An isomorphism theorem for Ginzburg-Landau interface models and scaling limits. (See Abstract below.) *Date and Time:* Thursday May 4, 16:30-17:30 (Rome time zone). Place: *Aula 3014, Dip. di Matematica e Applicazioni, Univ. di Milano-Bicocca*, Via R. Cozzi 55, Milano. *Webex link:* https://unimib.webex.com/unimib-it/j.php?MTID=mc07da73e64ea2eb0da78975bc808… *Meeting number:* 2741 491 0178*Password: *HPxNQASR579 (47967277 for phones) %%%%%%%%%% *Abstract: *We introduce a natural measure on bi-infinite random walk trajectories evolving in a time-dependent environment driven by the Langevin dynamics associated with a gradient Gibbs measure with convex potential. We derive an identity relating the occupation times of the Poissonian cloud induced by this measure to the square of the corresponding gradient field, which - generically - is not Gaussian. In the quadratic case, we recover a well-known generalization of the second Ray-Knight theorem. We further determine the scaling limits of the various objects involved in dimension 3, which are seen to exhibit homogenization. In particular, we prove that the renormalized square of the gradient field converges under appropriate rescaling to the Wick-ordered square of a Gaussian free field on R^3 with suitable diffusion matrix, thus extending a celebrated result of Naddaf and Spencer regarding the scaling limit of the field itself. (Based on joint work with Pierre-François Rodriguez.) %%%%%%%%%%% This talk is part of the *(PMS)^2: Pavia-Milano Seminar series on Probability and Mathematical Statistics* organized jointly by the universities Milano-Bicocca, Pavia, Milano-Politecnico. Participation is free and welcome!

De Finetti Risk Seminar - May 3, 2023
by Emanuela Rosazza Gianin 29 Apr '23

29 Apr '23

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: Jean-Pierre Fouque University of California Santa Barbara Title: Reinforcement Learning Algorithm for Mixed Mean Field Control Games Abstract: We present a new combined Mean Field Control Game (MFCG) problem which can be interpreted as a competitive game between collaborating groups and its solution as a Nash equilibrium between the groups. Within each group the players coordinate their strategies. An example of such a situation is a modification of the classical trader's problem. Groups of traders maximize their wealth. They are faced with transaction cost for their own trades and a cost for their own terminal position. In addition they face a cost for the average holding within their group. The asset price is impacted by the trades of all agents. We propose a reinforcement learning algorithm to approximate the solution of such mixed Mean Field Control Game problems. We test the algorithm on benchmark linear-quadratic specifications for which we have analytic solutions. Joint work with A. Angiuli, N. Detering, Mathieu Laurière, and J. Lin.

Seminar Prof. F. Patras at Università degli Studi di Milano
by Stefania Ugolini 28 Apr '23

28 Apr '23

Professor F. Patras (Univ. Côte d’Azur, CNRS) will give a seminar on Thursday, May 04th at 15:00, in Aula Dottorato, at the Department of Mathematics "Federigo Enriques", Università degli Studi di Miano. Title: "Wick polynomials, from classical to free probability." Abstract: Wick polynomials are a central object in quantum physics and classical probability (where they encode for example "chaos decompositions" - they provide an orthonormal basis of the space of square integrable functions of a Gaussian random variable). We will discuss an algebraic formulation of Wick's constructions that allows to generalize them to a wide variety of contexts, featuring free probability - a probability theory closely linked to random matrices but that appears in various recent works, in different areas.

Abstract: In various situations, one may be interested in the concept of differentiation of random variables or processes with respect to some underlying parameters. We will discuss this possibility in the case of random variables related to stopping times. Rather than discussing general theory (which we may), we will present basic examples that give hints about the general results and exhibit the difficulties involved in the development of general results. ________________________________ Fabio Antonelli DISIM - Università di L'Aquila

The C.r.e.d.i.t. 2023 is the*twenty-second *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*, *ABI - Italian Banking Association*,***AIAF - Associazione Italiana per l'Analisi Finanziaria* and *AIFIRM - Associazione Italiana Financial Industry Risk Managers*. Recent years have seen a series of crises (from health/pandemic to climate/energy) that have not only put a strain on global mechanisms previously seen as robust, but have exacerbated existing weaknesses and so increased vulnerability in new crisis situations. The social impact of the pandemic was partially mitigated by public interventions but social conditions then worsened with the soaring costs of energy, raw materials and inflation more broadly. Social and energy costs, which inevitably weigh on invidual countries and aggravate already delicate local situations (e.g., public debts), have led to growing geopolitical tensions, with global systemic consequences. The C.r.e.d.i.t. 2023 conference will be dedicated to Social, Sovereign and Geopolitical Risks to discuss, evaluate and address the near- and medium-term macro-financial impact of persistent crises (“permacrisis”) that can affect the stability of financial as well as socio-economic systems. The organizers encourage submissions on any topic within the overall theme of the conference and in the following areas in particular: * *Socio-economic Stability: *Future development of income (and wealth) inequality and social polarization; Risk, inequality and employment impacts of crises and policies; Gender and skilling issues will increase or help the transition?; * *Sovereign Risks: * Sovereign debt with low economic growth; Long term challenges for fiscal and monetary policies: green transformation, commodity prices, de-globalization and demographic trends; Inflation and exchange rate risks; Environmental and social inter-dependencies; social and environmental preferences and how these affect the stability and macroeconomic wellbeing of a given country; Challenges in measuring the ESG ratings of countries and thus of sovereign debt; * *Geopolitical Risks:* Global supply chain and de-globalization risks for finance; Do international energy price discrepancies pose risks for the competitiveness of EU firms’ and might this have implications for the real exchange rate to?; Risks stemming from accelerating deglobalisation; Cyber-risk vulnerabilities of banks and firms; * *Energy/Commodity Security:* Energy prices and financial performance of firms; Inefficiency of energy markets under scarcity; Transition costs under high energy and resource prices; Volatility of energy-related asset prices (both brown and green) and implications for medium and long term investments in energy production technologies, energy commodity assets and energy infrastructure; Implications of net zero policies for the prices of real estate assets, especially for homeowners and households; * *Long Run Investments and Portfolios:* Stability of asset market equilibria under low returns; Regulation (-demand) driven asset prices; Equilibrium asset price levels under structural transformation and high uncertainty; Net zero pledges and the possible trade-off between sustainability and returns; Engagement versus divesting. The final program will include both submitted and invited papers. Acceptances received so far from invited speakers include *Helen Rey* (London Business School), *Elisa Giuliani *(University of Pisa) and *Moritz Schularick *(Sciences Po Paris & University of Bonn). 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: *Moritz Schularick *(Sciences Po Paris & University of Bonn, Programme Chair) *Francesca Campolongo* (Joint Research Center, European Commission) *Rajna Gibson* (University of Geneva & Geneva Finance Research Institute) *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) *Loriana Pelizzon *(Ca’ Foscari University of Venice, Leibniz Institute for Financial Research SAFE & Goethe University) *Roberto Rigobon* (MIT Sloan School of Management) *Stephen Schaefer *(London Business School) *Marti Subrahmanyam *(NYU Stern Business School) *Christoph Trebesch* (Kiel Institute) 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).

Corso Paul JENKINS (University of Warwick)
by Matteo Ruggiero 24 Apr '23

24 Apr '23

Cari colleghi, nell’ambito del programma di Visiting Professors della Laurea Magistrale in Stochastics and Data Science dell’Università di Torino (programma completo alla pagina https://www.master-sds.unito.it/go/visiting), con piacere annunciamo il seguente corso: -------------------------------------- Paul JENKINS (University of Warwick) SIMULATION AND INFERENCE IN POPULATION GENETICS Population genetics provides a rich source of data. We now have the ability to sequence, cost-efficiently, the genomes of a large number of individuals from a species. Patterns of variation in DNA sequences offer a rich insight into biological and demographic processes: mutation, natural selection, past migration events, admixture, population structure, and so on. But such data are high-dimensional, noisy, and - because of shared ancestry - not independent, giving rise to some challenging statistical problems. In this course we will cover two important models for the analysis of genetic data - the coalescent, and the Wright-Fisher diffusion. We will discuss methods of simulation of data from these models, as well as how to perform inference for key biological and evolutionary parameters, using techniques such as MCMC. -------------------------------------- Il corso si svolgerà esclusivamente in presenza secondo il seguente calendario: - mar 2 Maggio, h.16-18 - mer 3 Maggio, h.16-18 - ven 5 Maggio, h.11.15-13.15 (Aula 3) - mar 9 Maggio, h.14-16 - mer 10 Maggio, h.16-18 - gio 11 Maggio, h.16-18 - mar 16 Maggio, h.14-16 - mer 17 Maggio, h.16-18 Sede dei corsi: Aula 11 (tranne il 5/5), Terzo piano - Corso Unione Sovietica 218/bis, 10134, Torino. Il corso è rivolto agli studenti della Laurea Magistrale ma la partecipazione è aperta a tutti gli interessati.

Seminario A. Stamm presso Politecnico di Milano
by Laura Maria Sangalli 24 Apr '23

24 Apr '23

Si avvisa che in data 26-04-2023, alle ore 14:30 precise presso il Politecnico di Milano, Dipartimento di Matematica (Edificio 14 - La Nave), in Aula Saleri (sesto piano), nell’ambito delle attività del MOX, si svolgerà il seguente seminario: Aymeric Stamm, Laboratoire de Mathématiques Jean Leray - UMR CNRS, Nantes, France Titolo: Clustering for rotation-valued functional data Abstract: This talk is motivated by the strong case study of monitoring gait for early detection of gait impairment in patients diagnosed with gait-affecting disorders. To this effect, we record the rotation of the hip over time. This leads to data with a great complexity that makes any kind of statistical analysis non-trivial. In effect, we collect functional data that evaluates on the Lie group of three-dimensional rotations which is a non-Euclidean space. In this work, we develop sound statistical methods to enable joint clustering and alignment of such functional data by borrowing ideas from the existing 𝑘-means alignment approach. In the process, we will describe in great length the R package fdacluster, which is an extension of the R package fdakma that provides a fast C++ based implementation of the k-mean alignment algorithm from Sangalli et al. (2010) as well as hierarchical clustering for functional data and tools that help choosing the number of clusters.

Seminario di Gérard Letac, Giovedì 27 Aprile, Sapienza Università di Roma
by Silvestri, Vittoria 23 Apr '23

23 Apr '23

Segnalo il seguente seminario, che si terrà Giovedì prossimo in Sapienza. Notare il giorno e l'aula inusuali. *Giovedì 27 Aprile, ore 14:00* Aula L, Dipartimento di Matematica, Sapienza Università di Roma *Speaker:* Gérard Letac (Paul Sabatier University - Toulouse III) *Title: *From the Matsumoto Yor observation to stationary measures for a discrete KdV model *Abstract: *Let F(x,y)=(u,v) from R2 into itself such that F∘F(x,y)=(x,y). The discrete Korteweg-de Vries model associated to F considers two dimensional vectors (x tn,ytn) indexed by (t,n)∈Z2 submitted to (xtn,ytn)=F(xt−1n,ytn−1). In the particular case F(x,y)=(y−1−(x+y)−1,(x+y)−1), by considerations on Brownian motion, Matsumoto-Yor in 1999 have found laws of independent random variables X,Y such that U,V defined by F(X,Y)=(U,V) are independent, obtaining stationary measures on the KdV model. In an extraordinary paper, Croydon and Sasada (2021) have generalized this result to the surprizing F(x ,y)=(yβxy+1αxy+1,xαxy+1βxy+1). The lecture will prove that if X,Y are independent and such that U,V=F(X,Y) are also independent, then the laws of X and Y are indeed the generalized Gaussian distributions discovered by Croydon and Sasada. This is joint work with Jacek Wesolowski (arXiv 2203.05404). *Nota*: Sul sito del dipartimento il seminario è, ad oggi, annunciato per le 17:00 (in Aula II), ma si terrà alle 14:00 (in Aula L), come annunciato in questa email. La pagina è in corso di aggiornamento. ******************************** Vittoria Silvestri Assistant Professor Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome ********************************

Seminar@UNIBO - ROSANNA GRASSI
by Fabrizio Lillo 22 Apr '23

22 Apr '23

*Tuesday May 2nd, 2023 12:00* *– 13:00* Dipartimento di Matematica, Università di Bologna Aula Seminario II, Piazza di Porta San Donato 5, Bologna Prof. Rosanna Grassi, Università degli Studi di Milano-Bicocca *Title: Higher order assortativity for directed weighted networks and Markov chains* Abstract: Assortativity is a global indicator that provides meaningful insights about the network structure. In the classical definition, the assortativity is a global measure based on the Pearson correlation between the degrees of nodes. This definition can be extended into two different directions. On the one side, one can consider other quantitative attributes of the nodes different from the degree; on the other side, one can move from the adjacency of the nodes – which is the basis of Newman’s degree-degree assortativity – and propose more general ways to connect them. We provide a generalized concept of the assortativity measure for directed and weighted networks, moving beyond the adjacency relations in both directions. The proposed concept is formulated on a node attribute that is not necessarily the degree or strength, and nodes are connected through walks or paths. In this way, we totally extend the assortativity definitions provided in the literature until now. We provide an empirical application of these measures for the paradigmatic case of the trade network. Interestingly, this interpretation of the higher-order assortativity measure allows stating a natural bridge between complex networks and stochastic processes. In so doing, we are able to move from the information content of the higher order assortativity of a network to the dynamical properties of the underlying Markov chain. Specifically, the temporal dimension of the network and the regularities captured by the autocorrelation – which are hidden in the network structure – become clear in moving to the Markov chain theory. ---------------------------------------- Fabrizio Lillo Dipartimento di Matematica, Università di Bologna Scuola Normale Superiore, Pisa ITALY Personal website: fabriziolillo.wordpress.com University website: www.unibo.it/sitoweb/fabrizio.lillo <http://fabriziolillo.wordpress.com/> phone: +39 050509159

OWABC- Emtiyaz Khan - The Bayesian Learning Rule - April 27, 9.30am UK time
by Massimiliano Tamborrino 21 Apr '23

21 Apr '23

Dear all, The One World ABC Seminar series www.warwick.ac.uk/oneworldabc<http://www.warwick.ac.uk/oneworldabc> is about to resume. Our next speaker will be Emtiyaz Khan<https://emtiyaz.github.io/> (RIKEN), who will talk about "The Bayesian Learning Rule" on Thursday, April 27, 9.30am UK time, with an abstract reported below. The talk will be hosted on MS Teams here<https://teams.microsoft.com/l/meetup-join/19%3ameeting_Yjk5MDQyYWMtZmI3Yy00…>. Title: The Bayesian Learning Rule. Abstract Humans and animals have a natural ability to autonomously learn and quickly adapt to their surroundings. How can we design machines that do the same? In this talk, I will present Bayesian principles to bridge such gaps between humans and machines. I will show that a wide-variety of machine-learning algorithms are instances of a single learning-rule derived from Bayesian principles. I will also briefly discuss the dual perspective yielding new mechanisms for knowledge transfer in learning machines. My hope is to convince the audience that Bayesian principles are indispensable for an AI that learns as efficiently as we do. References * The Bayesian Learning Rule, (Preprint) M.E. Khan, H.

He finished his PhD in machine learning from University of British Columbia in 2012. The main goal of Emti’s research is to understand the principles of learning from data and use them to develop algorithms that can learn like living beings. For more than 10 years, his work has focused on developing Bayesian methods that could lead to such fundamental principles. The approximate Bayesian inference team now continues to use these principles, as well as derive new ones, to solve real-world problems.

19 Apr '23

Dear all, On Wednesday, April 26th, at 14h00 in Aula 2001 (change of usual room! Aula 2001 is behind Aula Dal Passo) at Roma Tor Vergata, RoMaDS (https://www.mat.uniroma2.it/~rds/about.php) will host Federico Ricci Tersenghi (La Sapienza) with the seminar _ _ _"Phase transitions and algorithmic thresholds for optimization and inference problems on sparse random graphs__"_ _ _ Abstract: Focusing on some fundamental constraint satisfaction problems defined on sparse random graphs (e.g. random k-sat, random q-coloring) I will start summarizing the rich phase diagram of the solution space which has been derived using powerful techniques from statistical mechanics of disordered systems. I will then discuss the implications of some of these phase transitions for the behaviour of smart algorithms searching for solutions. In the second part, I will consider the problem of inferring a signal from noisy and/or incomplete data within the Bayesian framework called the teacher-student scenario. I will discuss the corresponding phase diagrams and how phase transitions may affect the performances of inference algorithms based on message-passing and Monte Carlo sampling. We encourage in-person partecipation. Should you be unable to come, here is the link to the event on Teams [1]. The seminar is part of the Excellence Project MatMod@TOV. Note that in the next month we will have plenty more of interesting seminars from mathematicians and computer scientists, save the dates! 03.05.2023 - Pierluigi Crescenzi (GSSI) 09.05.2023 - Arturo Kohatsu-Higa (Ritsumeikan University, Kyoto) 17*.05.2023 - Daniele Calandriello (Google Deep Mind, Paris) 24.05.2023 - Rongfeng Sun (NUS, Singapore) *exact date to be confirmed You can find a schedule with the next events at the following link: https://www.mat.uniroma2.it/~rds/events.php.

Mark Podolskij's seminar at LUISS (hybrid mode)
by Sara 17 Apr '23

17 Apr '23

Dear all, Professor Mark Podolskij ( https://wwwen.uni.lu/research/fstm/dmath/people/mark_podolskij) will give a seminar on *Thursday, April 20 at noon in room 205:* *Title * On Estimation of the Maximal Rank of Stochastic Volatility *Abstract* In this talk we address the question of how many Brownian motions are required to model a multivariate price process of diffusion type. It turns out that this question is equivalent to estimation of the maximal rank of the volatility component. We solve this mathematical problem in the high frequency regime and provide a formal estimation and testing procedure. If the time allows we touch upon high dimensional aspects of the problem. Please, find here the link to the seminar virtual room: Link room 205 B: https://luiss.webex.com/luiss-en/j.php?MTID=me3d961dc4b3575085d5d4b6a304e2d… guest username: w_guest(a)luiss.it pw : i7G3HiAKq2Q Best regards, Sara ---------------------------------------------------------------------------------------------- *Sara Biagini* Department of Economics and Finance *LUISS University* Address: Viale Romania, 32 00197 Roma *Web* (institutional): https://economiaefinanza.luiss.it/docenti/cv/352478 *Web* (personal): https://sites.google.com/site/sarabiagini/

To support my claims, I will focus on the Demographic Parity fairness constraint, describing various connections to classical statistical theory, optimal transport, and conformal prediction literature. In particular, we will study the form of an optimal prediction function under this constraint in both regression and classification. Then, I will describe a learning procedure which is supported by statistical guarantees under no or mild assumptions on the underlying data distribution. This talk is based on a sequence of joint works with Ch. Denis, S. Gaucher, M. Hebiri, L. Oneto, M. Pontil, and N. Schreuder. ------------------------------------------------ Sarà possibile seguire il seminario anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/89455985680?pwd=OXBPZSthaG5pRjZGbDNMVk9MMG1PQT09> 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 F. Mecatti (UNIMIB) presso il Politecnico di Milano
by Laura Maria Sangalli 17 Apr '23

Si avvisa che in data 21-04-2023, alle ore 14:30 precise presso il Politecnico di Milano, Dipartimento di Matematica, Aula Saleri sesto piano (Edificio 14 - La Nave), nell’ambito delle attività del MOX, si svolgerà il seguente seminario: Fulvia Mecatti, Università degli Studi Milano Bicocca Titolo: What is big in big data? A sampling statistician perspective Abstract: BigData users as well as BigData research community are fast growing bigger and bigger while statisticians at large seem to be growing divided between enthusiastic and worried, when not downright hostile. Is BigData also a big step ahead to extract information and actual knowledge from data? Is BigData underplaying statistical inference as we know it? Supplanting stats methodology as a low-cost futuristic option? As a (mainly) sampling statistician, in this webinar I shall try to decipher the multifaceted relationship connecting BigData to statistical and to sampling methodology, starting with the still blurry definition of BigData and discussing some very personal considerations and views. 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-seminars/?id_evento=2272 Tutti gli interessati sono cordialmente invitati a partecipare, Laura Sangalli —— Laura Maria Sangalli MOX - Dipartimento di Matematica Politecnico di Milano Piazza Leonardo da Vinci 32 20133 Milano - Italy (+39) 02 2399 4554 laura.sangalli(a)polimi.it https://sangalli.faculty.polimi.it <https://sangalli.faculty.polimi.it/>

SPASS Seminar: Vittoria Silvestri
by Francesco Grotto 11 Apr '23

11 Apr '23

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi: *Planar aggregation with subcritical fluctuations and the Hastings-Levitov models* Vittoria Silvestri (Università di Roma 1 La Sapienza) The seminar will take place on TUE, 18.4.2023 at 14:00 CET in Sala Seminari, Dipartimento di Matematica, Pisa 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: **The ALE (Aggregate Loewner Evolution) models describe growing random clusters on the complex plane, built by iterated composition of random conformal maps. A striking feature of these models is that they can be used to define natural off-lattice analogues of several fundamental discrete models, such as Eden or Diffusion Limited Aggregation, by tuning the correlation between the defining maps appropriately. In this talk I will discuss shape theorems and fluctuations of ALE clusters, which include Hastings-Levitov clusters as particular cases, in the subcritical regime. Based on joint work with James Norris and Amanda Turner.*

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 14 Aprile 2023, alle ore 12.00, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Speaker: *Peter Grunwald* (CWI and Universitet Leiden, Netherlands) Title: *E is for Evidence* Abstract: How much evidence do the data give us about one hypothesis versus another? The standard way to measure evidence is still the p-value, despite a myriad of problems surrounding it. We present the e-value, a recently popularized notion of evidence which overcomes some of these issues. While e-values were only given a name as recently as 2019, interest in them has since exploded with papers in the Annals, JRSS B, Biometrika and the like – June 2022 saw the first international workshop on e-values, a second one is planned. In simple cases, e-values coincide with Bayes factors. But if the null is composite or nonparametric, or an alternative cannot be explicitly formulated, e-values and Bayes factors become distinct and e-processes can be seen as a generalization of nonnegative supermartingales. Thus, unlike the Bayes factor, e-values always allow for tests with strict frequentist Type-I error control under optional continuation of data collection and combination of data from different sources. E-values are also the basic building blocks of anytime-valid confidence intervals that remain valid under continuous monitoring and optional stopping. In parametric settings they tend to be strictly wider than, hence consistent with Bayesian credible intervals. This led to the development of the e-posterior, an analogue to the Bayesian posterior that gets wider rather than wrong if the prior is chosen badly. This work is based on: P. Grunwald,. R. de Heide, W. Koolen (2023). Safe Testing. To appear in J. Roy. Stat. Soc., Series B P. Grunwald (2023) . The E-Posterior. Proc. Phil. Trans. Soc.

OWPS Tomorrow: Fabio Toninelli and Giuseppe Cannizzaro
by Alberto Chiarini 11 Apr '23

11 Apr '23

Dear all, A reminder that tomorrow (Wednesday), from 15:00 to 17:00 UTC (17:00 to 19:00 Central European Time), Fabio Toninelli (Technical University of Vienna) and Giuseppe Cannizzaro (University of Warwick) will be speaking at the One World Probability Seminar. 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. We kindly ask that you share this message within your community. With best wishes, Alberto Chiarini (Padua) and Adrián González Casanova (Berkeley and México) ---------------------------------------------------------------------------------------------------------- Talk : Fabio Toninelli (Technical University of Vienna) Title : Out-of-equilibrium phenomena, stochastic PDEs and Gaussian limits Abstract : I will report on mathematical progress on certain (non-linear, singular) stochastic PDEs that model effectively the mesoscopic behaviour of some out-of-equilibrium physical systems, most notably stochastic interface growth and driven diffusive systems. Scaling and Renormalization Group arguments suggest that, above the critical dimension d=2, the large-scale behaviour of these equations should be Gaussian. Our results imply, indeed, Gaussian scaling limits in dimension d\ge 3 (for driven diffusive systems) and also, at least in the regime of weak non-linearity, in the critical dimension d=2 (both for driven diffusive systems and for the Anisotropic KPZ equation). Talk : Giuseppe Cannizzaro (University of Warwick) 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 certain stationary SPDEs at the critical dimension. Our techniques are inspired by the resolvent method developed by Landim, Olla, Yau, Ramirez, and many others, in the context of particle systems in the supercritical dimension and might be well-suited to study a much wider class of statistical mechanics models at criticality.
