Short course - Kolyan RAY (Imperial)
by Matteo Ruggiero 28 Nov '24

28 Nov '24

Dear Colleagues, as part of the Visiting Professors program of the Master's Degree in Stochastics and Data Science at the University of Torino (full program available at https://www.master-sds.unito.it/go/visiting), we are pleased to announce the following short course: ——————————————————— Kolyan RAY (Imperial College London) POSTERIOR ASYMPTOTICS IN BAYESIAN NONPARAMETRICS This mini-course will cover an introduction into the asymptotic theory for Bayesian nonparametric procedures. This provides a useful tool to understand how prior choices can affect the statistical performance of the Bayes method in high or infinite dimensional models. We will cover the notion of posterior consistency and convergence rates, using Gaussian process priors as a canonical example. At the end, we will also touch on recent extensions of such theory to variational Bayes, which provides a scalable posterior approximation algorithm. ——————————————————— The course will be held exclusively in-person, according to the following schedule: - Tue Dec 10, h. 9.15-11.15 - Wed Dec 11, h. 11.15-13.00 - Thu Dec 12, h. 9.15-11.15 - Thu Dec 12, h. 14.00-16.00 Course location: Room 30, third floor, Corso Unione Sovietica 218/bis, 10134, Torino. The participation is open to everyone interested. Best regards, Matteo Ruggiero --- Matteo Ruggiero University of Torino and Collegio Carlo Alberto www.matteoruggiero.it

Seminario Padova - Alex Delalande
by alekos.cecchin＠unipd.it 28 Nov '24

28 Nov '24

Buongiorno a tutti, Vorremmo segnalarvi che venerdì prossimo (29 Novembre) alle ore 14:30 in aula 2BC30 (Torre Archimede, Università di Padova) ci sarà un seminario per il ciclo di seminari in Probabilità e Finanza di: Alex Delalande (EPFL Losanna) https://alex-delalande.github.io Title: Sharper Exponential Convergence Rates for Sinkhorn's Algorithm in Continuous Settings Date: November 29, 2024, at 14:30, room 2BC30 Abstract: In this talk, I will present recent results I obtained in collaboration with Lénaïc Chizat and Tomas Vaškevičius regarding the convergence rate of Sinkhorn's algorithm for solving entropy-regularized optimal transport problems, in the context where at least one of the probability measures, say \mu, admits a density over \R^d. For a semi-concave cost function bounded by c∞ and a regularization parameter λ>0, we obtained exponential convergence guarantees on the dual sub-optimality gap with contraction rates that are polynomial in λ/c∞. This represents an exponential improvement over the known contraction rate 1−Θ(exp(−c∞/λ)) achievable via Hilbert's projective metric. Specifically, we proved a contraction rate value of 1−Θ(λ²/c²∞) when has a bounded log-density. In some cases, such as when is log-concave and the cost function is c(x,y)=−⟨x,y⟩, this rate improves to 1−Θ(λ/c∞). The latter rate matches the one that we derived for the transport between isotropic Gaussian measures, indicating tightness in the dependency in λ/c∞. Our results are fully non-asymptotic and explicit in all the parameters of the problem. Vi aspettiamo numerosi!

Carlo Ciliberto at Tor Vergata 03.12
by Michele Salvi 26 Nov '24

26 Nov '24

Dear all, On Tuesday, December 3rd, at 14h00 in Aula Dal Passo of Tor Vergata Math Department, RoMaDS (https://www.mat.uniroma2.it/~rds/events.php) will host Carlo Ciliberto (University College London) with the seminar “Operator World Models for Reinforcement Learning” Abstract: Policy Mirror Descent (PMD) is a powerful and theoretically sound methodology for sequential decision making. However, it is not directly applicable to Reinforcement Learning (RL) due to the inaccessibility of explicit action-value functions. We address this challenge by introducing a novel approach based on learning a world model of the environment using conditional mean embeddings. Leveraging tools from operator theory we derive a closed-form expression of the action-value function in terms of the world model via simple matrix operations. Combining these estimators with PMD leads to POWR, a new RL algorithm for which we prove convergence rates to the global optimum. Preliminary experiments in finite and infinite state settings support the effectiveness of our method. We encourage in-person partecipation. Should you be unable to come, here is the link to the Teams streaming: https://teams.microsoft.com/l/meetup-join/19%3arfsL73KX-fw86y1YnXq2nk5VnZFw…"Tid"%3a"24c5be2a-d764-40c5-9975-82d08ae47d0e"%2c"Oid"%3a"650fc4a8-4cec-4bd2-87bc-90d134074fe6"} <https://teams.microsoft.com/l/meetup-join/19%3arfsL73KX-fw86y1YnXq2nk5VnZFw…> The seminar is part of the Excellence Project MatMod@TOV.
