SPASS Seminar: Olga Ariasova
by Francesco Grotto 10 Feb '25

10 Feb '25

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi: *Homogenization of a multivariate diffusion with semipermeable reflecting interfaces* by Olga Ariasova (Inst. Geophys. Nat. Acad. Sciences of Ukraine, F. Schiller Univ. of Jena) The seminar will take place tomorrow TUE, 11.2.2025 at 14:00 CET in Aula Seminari, Dipartimento di Matematica, UNIPI and streamed online at the link below. The organizers, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass *---------------------------------------------------------* *Abstract: * The mathematical problem of homogenization typically involves studying the effective parameters of a system that exhibits rapid variations in its spatial characteristics. However, we focus on a stochastic multivariate homogenization problem of a different kind: the diffusion in the presence of narrowly located semipermeable interfaces. In simple words, our model reminds of a foiled composite material consisting of a media interlaced with very thin plates of different permeability. In material science such models are referred to as reinforced materials like a glass wool reinforced by aluminium foil. Usually, one is interested in the effective parameters of such a system. By combining the study of stochastic differential equations with local times and homogenization, we explore how the presence of interfaces can alter the diffusion behavior of the limit process. As a byproduct of our research, we obtain theorems for the existence and uniqueness of solutions to SDEs for multidimensional diffusion processes with membranes. Uniqueness is a problem of particular interest because it implies the strong Markov property of the solution, which is essential for the proof of convergence.

08 Feb '25

Buongiorno a tutti, Vorremmo segnalarvi che venerdì prossimo (14 Febbraio) in aula 2BC30 (Torre Archimede, Università di Padova) ci sarà un seminario per il ciclo di seminari in Probabilità e Finanza di: Stefan Ankirchner (Friedrich-Schiller-Universität Jena) Title: Diffusion control ranking games Date: February 14, 2025, at 11:00, room 2BC30 Abstract: The topic of the talk are stochastic differential games where each player can control the diffusion intensity of an individual state process, and the players whose final states are among the highest receive a fixed prize. We take a closer look at the 2 player case and the mean field version of the game. The talk is based on several papers written jointly with Nabil Kazi-Tani, Julian Wendt and Chao Zhou. Vi aspettiamo numerosi! Alberto Chiarini e Alekos Cecchin

Seminars in Statistics at Collegio Carlo Alberto - Yufei ZHANG (IMPERIAL COLLEGE LONDON)

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.google.com/url?q=https://www.carloalberto.org/events/category/s…> Venerdì 14/02/2025, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ 12.00-13.00 Speaker: Yufei ZHANG (IMPERIAL COLLEGE LONDON) Title: Towards sample-efficient continuous-time reinforcement learning Abstract: Recently, reinforcement learning (RL) has garnered significant research interest. However, much of this attention and success has been focused on the discrete-time setting. RL for continuous-time systems, despite its natural applicability to a wide range of control tasks in physical systems, remains largely unexplored with limited progress. In particular, characterizing the sample efficiency of continuous-time RL algorithms continues to be a challenging and open problem. In this talk, we introduce a principled framework for systematically analyzing regret bounds for continuous-time RL algorithms in episodic model-based settings. Our framework decomposes the regret analysis into two fundamental components: the finite-sample accuracy of model estimation and the performance gap of a greedy policy derived from the estimated models. The finite-sample accuracy is analyzed using filtering theory and concentration inequalities for correlated observations, while the performance gap is quantified by leveraging the robustness of the control problem. By integrating these insights, we optimize the exploration-exploitation trade-off, achieving the best-known sample complexity in the current literature. ------------------------------------------------ Sarà possibile il seminario anche in streaming: chiunque volesse collegarsi è pregato di inviare una email entro *mercoledì 12/02/2025* a matteo.giordano(a)unito.it <mailto:matteo.giordano@unito.it>.
