Dear colleagues, next Thursday, May 21 at 11:00 a.m. in Arzelà (5th floor, Department of Mathematics, Piazza di Porta San Donato, Bologna), there will be a seminar by Jodi Dianetti, University of Rome Tor Vergata, entitled: "REINFORCEMENT LEARNING FOR EXPLORATORY OPTIMAL STOPPING: A SINGULAR CONTROL FORMULATION" and abstract "In this talk we discuss continuous-time and state-space optimal stopping problems from a reinforcement learning perspective. We begin by formulating the stopping problem using randomized stopping times, where the decision maker's control is represented by the probability of stopping within a given time--specifically, a bounded, non-decreasing, càdlàg control process. To encourage exploration and facilitate learning, we introduce a regularized version of the problem by penalizing it with the cumulative residual entropy of the randomized stopping time. The regularized problem takes the form of an (n+1)-dimensional degenerate singular stochastic control with finite-fuel. We address this through the dynamic programming principle, which enables us to identify the unique optimal exploratory strategy. For the specific case of a real option problem, we derive a semi-explicit solution to the regularized problem, allowing us to assess the impact of entropy regularization and analyze the vanishing entropy limit. Finally, we propose a reinforcement learning algorithm based on policy iteration. We show policy improvement results for our proposed algorithm. This talk is based on a joint project together with Giorgio Ferrari and Renyuan Xu."

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.google.com/url?q=https://www.carloalberto.org/events/category/s…> Martedì 26/05/2026, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ 12.00-13.00 Speaker: Yuqiong WANG (UNIVERSITY OF MICHIGAN) Title: Optimal match lengths in knock-out tournaments Abstract: Later-stage matches in sports tournaments, especially semifinals and finals, are often treated as more important and therefore played longer. We ask whether this intuition can be justified from a sequential testing viewpoint. We study a knock-out tournament with $2^n$ players in which each match is modeled by a Brownian motion with an unobservable drift, representing the players' relative abilities. The tournament designer chooses how long each match should be played so that the strongest player wins the tournament with a prescribed probability. We analyze two design regimes: $(i)$ deterministic designs, where all match lengths are fixed in advance, and $(ii)$ sequential designs, where match duration can adapt to the observed paths. Our main structural result shows that in both regimes, the optimal schedule makes the late-round matches longer than early-round matches, providing a formal statistical justification for common tournament practice. We also quantify the efficiency gain from allowing sequential decisions: sequential testing saves at least $36\%$ and at most $75\%$ on average. Moreover, the relative advantage of sequential methods grows as one requires higher precision. ------------------------------------------------ Sarà possibile seguire il seminario anche in streaming: chiunque volesse collegarsi è pregato di inviare un’email a matteo.giordano(a)unito.it <mailto:matteo.giordano@unito.it> Il webinar è organizzato dalla "de Castro" Statistics Initiative (www.carloalberto.org/stats <http://www.carloalberto.org/stats>) in collaborazione con il Collegio Carlo Alberto.

Seminar Severo at Tor Vergata, May 18th
by Michele Salvi 14 May '26

14 May '26

Dear all, Next Monday RoMaDS will host at the Department of Mathematics of the University of Rome, Tor Vergata the seminar > Monday, 18th May Franco Severo (Sorbonne Université) "Level set percolation of smooth Gaussian fields: an overview" 14h00-15h00, Department of Mathematics, Aula Dal Passo. Abstract Consider the connected components of the level sets of a smooth Gaussian field on the d-dimensional Euclidean space. For which levels does an unbounded connected component appear? When it exists, is it unique? What is the typical size of large bounded components and how does it depend on the level? What happens at the critical level? How do the answers to these questions depend on the dimension and on the correlation decay? These natural questions lie at the heart of level-set percolation of smooth gaussian fields, a topic that has seen significant progress over the past decade. In this talk, I will give an overview of several recent results in the field and highlight a number of open problems that remain to be addressed. We encourage in-person partecipation. Should you be unable to come, here is the link to the Teams streaming: https://teams.microsoft.com/meet/324713312710924?p=fSpsvvN4aZ6M6ZjvFk The seminar is part of the Excellence Project MatMod@TOV.

ISBA-BNP June 2026 special interview webinar: Eugenio Regazzini
by Tommaso Rigon 13 May '26

13 May '26

Dear all, Apologies for cross-posting. The Bayesian Nonparametric Section of ISBA is excited to announce a special interview webinar in the ISBA-BNP webinar series. Details about upcoming webinars, including the Zoom Registration link for this event, can be found at https://bnp-isba.github.io/webinars.html <https://u8042292.ct.sendgrid.net/ls/click?upn=u001.VwavI53V6vcw3NkZZaT5c3BC…> DATE & TIME: 15:00 UTC on Thursday June 4th, 2026. Note that 15:00 UTC corresponds to 11:00 US Eastern (EDT) and 17:00 Central European (CEST). SPEAKER: Eugenio Regazzini (University of Pavia) DESCRIPTION: This special interview webinar features a recorded interview with Prof. Eugenio Regazzini, conducted by Antonio Lijoi and Igor Prünster. Regazzini retraces his scientific itinerary from his student years at Bocconi in the late 1960s, when his thesis on hypothesis testing was assigned in an Italian landscape still dominated by Gini's descriptive tradition. He describes the state of probability and statistics in Italy in the late '60s and '70s, recalling the small network of probability chairs of the time and the "return" of de Finetti's ideas to Italy after Savage had championed them in the United States. He then recounts his long-standing collaboration with Donato Michele Cifarelli and the spark that led them into Bayesian nonparametrics — a 1935 abstract by de Finetti on "perequazione", combined with Ferguson's work on the Dirichlet process — which gave rise to their study of the distribution of the mean of a Dirichlet random measure (the Cifarelli–Regazzini identity). The interview closes with a reflection on what it means to be a subjectivist in the spirit of de Finetti, and with reading recommendations for young Bayesians. The interview is in Italian, with carefully curated English subtitles. Following the recording, there will be a live discussion with Prof. Regazzini.
