20 Apr '23

Dear friends, this is the last announcement for the summer school "Statistical Mechanics and Stochastic PDEs" which will be held from Sep 11-15, 2023, in Cetraro, Italy. It belongs to the series of mathematics summer schools organised yearly by Fondazione CIME. The school aims to expose researchers to some of the latest developments in statistical mechanics and stochastic PDEs, as well as the connections between the two. The list of speakers and their updated course titles is: Massimiliano Gubinelli (Univ. Oxford, UK) - Constructive stochastic quantization Antti Kupiainen (Univ. Helsinki, Finland) - Constructive Conformal Field Theory: the case of the Liouville Model Ioan Manolescu (Univ. Fribourg, Switzerland) - An invitation to FK percolation Fabio Lucio Toninelli (Technical Univ. Vienna, Austria) - Large-scale behavior of (super-)critical stochastic PDEs We especially encourage the participation of PhD students and postdocs. A limited number of grants will be available to cover their local expenses (full board accommodation). Interested participants should submit their applications before Apr 30, 2023, through the school website: https://sites.google.com/unifi.it/cime/c-i-m-e-courses/c-i-m-e-courses-2023… <https://sites.google.com/unifi.it/cime/c-i-m-e-courses/c-i-m-e-courses-2023…> Some practical details on the location: https://sites.google.com/unifi.it/cime/c-i-m-e-courses/c-i-m-e-courses-2022… <https://sites.google.com/unifi.it/cime/c-i-m-e-courses/c-i-m-e-courses-2022…> Please feel free to circulate the information.

Seminar: Federico Ricci Tersenghi at Tor Vergata
by salvi 19 Apr '23

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/

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 21 Aprile 2023, alle ore 12.00, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Speaker: *Evgenii Chzhen* (Université Paris-Saclay, France) Title: *Demographic parity constraint for algorithmic fairness : a statistical perspective* Abstract: In this talk I will give a brief introduction to the recently emerged field of algorithmic fairness and advocate for a statistical study of the problem. 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

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/>
