Seminario di Gustavo Posta a Roma Tre il 03/06/2026 alle 13
by Pietro Caputo 03 Jun '26

03 Jun '26

Mercoledì *3 giugno *alle ore* 13.00*, Gustavo Posta (La Sapienza, Roma) terrà il seminario di Probabilità e Fisica Matematica dal titolo *"A perturbative criterion for ergodicity of quantum lattice systems".* Abstract: We analyze a class of quantum Feller semigroups describing the evolution of quantum interacting systems on a lattice. By regarding this evolution as a perturbation of a non-interacting dissipative dynamics, we obtain a purely dynamical quantitative criterion that implies uniqueness of the stationary state and exponential convergence of local observables. Il seminario si svolgerà in presenza presso il Dipartimento di Matematica e Fisica, Largo San Leonardo Murialdo - 1, aula* B308*. -- Pietro Caputo Dipartimento di Matematica e Fisica Universita Roma Tre www.mat.uniroma3.it/users/caputo

REMINDER: ISBA-BNP June 2026 special interview webinar: Eugenio Regazzini
by Tommaso Rigon 02 Jun '26

02 Jun '26

Dear all, Apologies for cross-posting. This is a reminder of the upcoming special interview webinar in the ISBA-BNP webinar series, organized by the Bayesian Nonparametric Section of ISBA. Details about upcoming webinars, including the Zoom Registration link for this event, can be found at https://bnp-isba.github.io/webinars.html 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. Best regards, Tommaso Rigon ------------------------ Tommaso Rigon Associate Professor of Statistical Science University of Milano-Bicocca https://tommasorigon.github.io

[SURE-AI@STAR Midsummer on Reinforcement Learning] June 23-25 - Xin Guo
by Leonardo Tarquini 02 Jun '26

02 Jun '26

Dear all, Join us for our upcoming workshop SURE-AI@STAR Midsummer on Reinforcement Learning. The event will take place on three different days in a hybrid format: participants in Oslo can attend the talk in Room 723 in Niels Henrik Abels hus, whereas the international audience will be able to follow the talk via Zoom (see link next to each talk). The lecturer is Xin Guo (UC Berkeley). Title: A control-theoretical perspective of continuous-time reinforcement learning Abstract: Reinforcement Learning (RL) is a cornerstone of modern machine learning, enabling agents to learn optimal decision-making through interaction with complex environments and other agents. While RL was traditionally developed for discrete-time settings, many real-world physical and financial systems are intrinsically continuous. This series of lectures provides a comprehensive overview of recent advancements in continuous-time RL, analyzed through the rigorous lens of stochastic control theory. It consists of three parts. Registration<https://nettskjema.no/a/630234> is free, but mandatory for both in-person and online attendees to ensure the best logistics. The seminar link will be shared with all registered participants before the event starts. Part I. Foundations: Q-Functions and Dynamic Programming (23/06/2026, 13:00-16:00) We begin by establishing a bridge between RL and classical control theory. By leveraging the Dynamic Programming Principle (DPP) and the Feyman-Kac formula, we explore the similarities between these fields, specifically through the lens of continuous-time Q-functions, and martingale characterization. References [1] Gu, Guo, Wei, Xu (2020). Dynamic programming principle for mean field controls with learning. Operations Research, 2023. Arxiv: 1911.07314. [2] Gu, X. Guo, Wei, Xu (2021) Mean-Field controls with Q-learning for cooperative MARL: convergence and complexity analysis. SIAM Journal on Mathematics of Data Science. ArXiv:2002.04131. [3] Cheng, Guo, Zhang (2025). Bridging discrete and continuous RL: stable deterministic policy gradient with martingale characterization. arXiv:2509.23711. Part II. The Theoretical Divide: Regret Analysis and BSDEs (24/06/2026, 13:00-16:00) To distinguish RL from classical control, we analyze ``the cost of learning'' through regret analysis. This section delves into the mathematical tools required to quantify performance gaps when the system model is unknown. We show how the regularity of Hamilton-Jacobi-Bellman (HJB) equations and Backward Stochastic Differential Equations (BSDEs) enables establishing regret bounds. In the particular case of Linear-Quadratic (LQ) Models: we present proofs for logarithmic regret in episodic finite-horizon RL via regularities of the Riccati equation.

SIAM J. on Control Optimization (SICON). Arxiv.org/abs/2104.09311<http://arxiv.org/abs/2104.09311>. Part III. Modern Frontiers: Transfer Learning and Rough Paths (25/06/2026, 13:00-16:00) Finally, we explore how cutting-edge developments from Large Language Models (LLMs), such as transfer learning, can be integrated into RL to significantly boost algorithmic performance. We discuss fast policy learning for LQ control using entropy techniques to balance exploration and exploitation. We will also uncover how the regularity of rough paths provides a framework for analyzing policy transfer in continuous-time RL, offering a robust mathematical foundation for cross-domain adaptation.
