Seminario Padova - Simone Baldassarri
by alekos.cecchin＠unipd.it 20 Oct '25

20 Oct '25

Buongiorno a tutti, Vorremmo segnalarvi che venerdì prossimo (3 Ottobre) in aula 2AB40 (Torre Archimede, Università di Padova) ci sarà un seminario per il ciclo di seminari in Probabilità e Finanza di: Simone Baldassarri (Gran Sasso Science Institute (GSSI)) <https://sites.google.com/view/simonebaldassarri> https://sites.google.com/view/simonebaldassarri Title: How opinions evolve on dense dynamic random graphs Date: October 3, 2025, at 14:30, 2AB40 Abstract: Describing the evolution of dynamic networks together with dynamic processes running on them constitutes a major challenge in network science. Despite considerable efforts in past years, and notable progress on an intuitive and approximative level, our mathematical understanding of such systems is still in its infancy. The focus of this talk will be two-opinion voter models on dense dynamic random graphs. The goal is to understand and describe the occurrence of consensus versus polarisation over long periods of time. The former means that all vertices have the same opinion, the latter means that the vertices split into two communities with different opinions and few disagreeing edges. We consider three models for the joint dynamics of opinions and graphs: one with one-way feedback and two with two-way feedback. Key results cover functional laws of large numbers for the densities of the two opinions, functional laws of large numbers for the dynamic random graphs in the space of graphons, and a characterisation of the limiting densities in terms of Beta-distributions. This talk is based on a joint work with P. Braunsteins, F. den Hollander and Michel Mandjes. Vi aspettiamo numerosi!

MOX COLLOQUIA - Mark Girolami - 9 Ottobre - Politecnico di Milano
by Laura Maria Sangalli 30 Sep '25

30 Sep '25

Cari Colleghi, vi segnalo il seguente seminario della serie dei MOX COLLOQUIA: 09.11.25 ore 14:00 - Aula Consiglio, Edificio 14, Politecnico di Milano Speaker: Mark Girolami, University of Cambridge, Department of Engineering and The Alan Turing Institute Titolo: Statistical Finite Element Methods Abstract: The finite element method (FEM) is one of the great triumphs of applied mathematics, numerical analysis and software development. Recent developments in sensor and signalling technologies enable the phenomenological study of complex natural and physical systems. The connection between sensor data and FEM has been restricted to solving inverse problems placing unwarranted faith in the fidelity of the mathematical description of the system under study. If one concedes mis-specification between generative reality and the FEM then a framework to systematically characterise this uncertainty is required. This talk will present a statistical construction of the FEM which systematically blends mathematical description with data observations by endowing the Hilbert space of FEM solutions with the additional structure of a Probability Measure. This initiative is part of the “Ph.D. Lectures” activity of the project "Departments of Excellence 2023-2027" of the Department of Mathematics of Politecnico di Milano. This activity consists of seminars open to Ph.D. students, followed by meetings with the speaker to discuss and go into detail on the topics presented during the talk. Contatto: laura.sangalli(a)polimi.it<mailto:laura.sangalli@polimi.it> Il seminario sarà accessibile online: https://mox.polimi.it/mox-colloquia-seminars-list/mox-seminars/?id_evento=2… https://cassyni.com/events/LTNPwiAikdgXq3b4oMwNvR Per seguire il seminario in streaming, è necessario iscriversi (gratuitamente) sulla piattaforma Cassyni. Seguirà rinfresco presso il Dipartimento di Matematica.

Oct 21 - Stats seminars Geneletti and Wrobleski @ Sapienza MEMOTEF
by Francesca Panero 29 Sep '25

29 Sep '25

Buongiorno a tutti, On Tuesday 21st of October at the MEMOTEF Department, Sapienza University, we will have the pleasure to listen to the seminars of Prof Sara Geneletti<https://www.lse.ac.uk/statistics/people/sara-geneletti> and the PhD student Trevor Wrobleski<https://trevorwrobleski.github.io/> from the Department of Statistics of the London School of Economics and Political Science. The seminars will take place 10-11am in Laboratorio Antonio Amato - Sala Corsi (on the third floor of Palazzina Presidenza, the staircase at the entrance of the Economics building, Via del Castro Laurenziano 9). You can find titles and abstracts below. Best wishes, Francesca Sara Geneletti Bayesian interrupted time-series models and their applications on welfare and mental health This talk is an overview of the research output of the Epitome project funded by the Wellcome Trust. The project involved 4 research streams, and we showcase results from each one of them. The main aims of this project were to a) understand the impact of Conservative government and their "austerity" policy which led to widespread cuts in social spending and b) to develop novel methodologies in the context of interrupted time series designs using Bayesian methods. Our project found that changes in welfare benefits had a detrimental effect on mental health which also had a spatial dimension, and that the impact of the "hostile environment policy", an anti-immigration policy on the mental health of African and Carribean communities was negative. We further extended the Bayesian Structural Time Series approach to accommodate multiple data points and confirmed the impact of the hostile environment policy using this alternative method. Finally, we developed a Cohort Markov Model to evaluate the impact of the welfare benefits change by looking at how it impacted different segments of the population. Trevor Wrobleski Robustness and Sensitivity in Bayesian Dose-Response Risk Assessment Bayesian methods are increasingly central to toxicological risk assessment, yet their application to sparse dose-response data presents unique challenges. This presentation examines three drivers of analytical robustness: (i) the choice of likelihood for overdispersed quantal data, (ii) the inferential impact of selective dose-group deletion, and (iii) the sensitivity of results to prior specification. Using simulations and a case study of antimony trioxide carcinogenicity, we quantify the impact of these choices on benchmark dose (BMD) estimates and the posterior distribution, using metrics like Mean Squared Error and symmetrized Kullback-Leibler (KL) divergence. Our findings show that modeling overdispersion with a Beta-Binomial likelihood is important for accurate uncertainty quantification. We also demonstrate that deleting informative mid-range dose groups can degrade precision and shift inference. Finally, for the Dichotomous Hill model, the prior on the Hill coefficient is the dominant lever on the BMD, capable of inducing multi-fold changes in the risk estimate. ------------------------------------------- Dr Francesca Panero (she/her) Assistant Professor in Statistics (RTT), Department of Methods and Models for Economics, Territory and Finance Sapienza University, Rome Visiting Fellow, Department of Statistics London School of Economics and Political Science Visiting Lecturer, Faculty of Informatics Università della Svizzera Italiana Website: https://francescapanero.github.io

Seminario on-line PRISMA lunedì 6 ottobre 2025 - C. Franceschini & F. Sau
by Sonia Mazzucchi 25 Sep '25

25 Sep '25

Seminari on-line del gruppo UMI - PRISMA (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. Dallo scorso anno le registrazioni dei seminari vengono pubblicate sul canale YouTube dell'UMI: https://youtube.com/playlist?list=PLmySpc-jrtAMq84VH71evyqPc1hl6eEQb Il prossimo appuntamento è per *lunedì 6 ottobre* 2025. I relatori saranno *Chiara Franceschini* (Università di Modena e Reggio Emilia) e *Federico Sau* (Università di Milano Statale) che parleranno di: *Sistemi interagenti del non-equilibrio: dualità e gap spettrali* 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://unitn.zoom.us/j/83547578084 ID riunione: 835 4757 8084 Codice d’accesso: 873866 Vi aspettiamo numerosi! Alberto Chiarini e Sonia Mazzucchi %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Chiara Franceschini (Università di Modena e Reggio Emilia) e Federico Sau (Università di Milano Statale) TITOLO: Sistemi interagenti del non-equilibrio: dualità e gap spettrali RIASSUNTO: In questo seminario verranno presentati alcuni modelli di sistemi interagenti con spin sia discreti che continui. Tra gli esempi principali figurano il modello di Kipnis-Marchioro-Presutti (1982) e il processo armonico recentemente introdotto. Quando questi modelli sono studiati su un reticolo unidimensionale in contatto con reservoir ai bordi, costituiscono un setting classico per l’analisi di fenomeni tipici della meccanica statistica fuori dall’equilibrio. Tutti i modelli considerati sono associati alla Lie algebra su(1,1) e condividono diverse caratteristiche strutturali, tra cui la proprietà di dualità. Nella prima parte del seminario introdurremo il concetto di dualità per i processi di Markov, illustrando come esso consenta di derivare limiti di scala macroscopici (come l’equazione idrodinamica e i principi di grandi deviazioni) e ottenere informazioni sulla misura stazionaria fuori dall’equilibrio, esplicitamente nota solo per alcuni casi specifici. Nella seconda parte prenderemo in esame modelli definiti anche su grafi arbitrari, focalizzandoci sullo studio del gap spettrale e sulla convergenza all’equilibrio.
