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

Si segnala il seguente seminario a tutti gli interessati. Giovedì 5 Giugno 2024, ore 15. Aula Seminari - III Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Martin Kolodziejczyk, Politecnico di Milano Title: McKean-Vlasov SPDEs Abstract: We consider McKean-Vlasov Stochastic Partial Differential Equations with additive noise. We will focus on their well-posedness and long-time behaviour; showing that, under some assumptions on the spatial regularity of the noise, these SPDEs are well-posed and the semigroup resulting from them is strong Feller and irreducible. This is based on joint work with L. Angeli, J. Barrè and M. Ottobre.

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. 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… Tutti gli interessati sono cordialmente invitati a partecipare.

Seminario PRISMA oggi
by Francesco Caravenna 03 Jun '24

03 Jun '24

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> %%%%%%%%%%%%%%%%%%%%%%%%%%%%
