SEMINARIO presso Politecnico di Milano - 02.07.26 ore 14:30 - M. Pegoraro
by Laura Maria Sangalli 29 Jun '26

29 Jun '26

Cari Colleghi, A seguire annuncio di un seminario organizzato presso il Laboratorio MOX - Politecnico di Milano Matteo Pegoraro, Università della Svizzera italiana 02.07.26 ore 14:30 – Aula Saleri Link: https://mox.polimi.it/mox-colloquia-seminars-list/mox-seminars/?id_evento=2… Titolo: Topological Data Analysis: Invariance Properties, Statistical Problems, and Topological Machine Learning Abstract: I will present some of my contributions to Topological Data Analysis through the problem of building rigorous and usable TDA pipelines. Starting from a function, mesh, or point cloud, one builds a filtration and extracts a topological summary, such as a persistence diagram, merge tree, or Reeb graph. I will discuss how these summaries encode coordinate-free and invariant information, and why turning this idea into a robust mathematical pipeline requires carefully designed metrics, stability results, and estimation procedures, using tools from topology, geometry, statistics, and optimal transport. This perspective also exposes a second difficulty: even once stable summaries have been constructed, many of them naturally live in non-linear metric spaces, making standard statistical and machine-learning methods difficult to apply directly. I will therefore conclude with recent work on Persistence Spheres, an explicit Hilbert-space embedding of persistence diagrams with provable bi-continuity, aimed at making topological summaries compatible with modern machine-learning pipelines. Un caro saluto a tutti, Laura Sangalli —— Laura Maria Sangalli MOX - Dipartimento di Matematica Politecnico di Milano Piazza Leonardo da Vinci 32 20133 Milano - Italy (+39) 02 2399 4554 laura.sangalli(a)polimi.it https://sangalli.faculty.polimi.it

Mini-mini course Alberto Bietti at Tor Vergata, June 30
by Michele Salvi 23 Jun '26

23 Jun '26

Dear all, It is not time to go to the seaside yet! On Tuesday, June 30th, at 14h00 in Aula Dal Passo in the Math Department of the University of Rome Tor Vergata, RoMaDS will host Alberto Bietti (Flatiron Institute, NYC), with the mini-mini-course (about 3 hours long) “Learning in Transformers with Associative Memories” Abstract: Large language models based on transformers have achieved great empirical successes. However, as they are deployed more widely, there is a growing need to better understand their internal mechanisms in order to make them more reliable. These models appear to store vast amounts of knowledge from their training data, and to adapt quickly to new information provided in their context or prompt. Through toy tasks for reasoning and factual recall, we highlight the role of weight matrices as associative memories, and provide theoretical results on how gradients enable their learning during training, how over-parameterization affects their storage capacity, and sample complexity. We encourage in-person partecipation. Should you be unable to come, here is the link to the Teams streaming: https://teams.microsoft.com/meet/366597487320635?p=lk1ffPDon4Quh9ygMt The seminar is part of the Excellence Project MatMod@TOV.

Midsummer SURE-AI @ STAR seminars
by Leonardo Tarquini 19 Jun '26

19 Jun '26

Dear All, Midsummer is approaching with plenty to enjoy! The program features Xin Guo, University of Berkely with three lectures on Reinforcement Learning, Backward equations, LLM, and Rough Paths: SURE-AI@STAR Midsummer on Reinforcement Learning - Department of Mathematics <https://www.mn.uio.no/math/english/research/groups/risk-stochastics/events/…> mn.uio.no<http://mn.uio.no> You can register at the following link<https://nettskjema.no/a/619433#/page/1>. Also, we are pleased to announce the upcoming talk in the SURE-AI @ STAR seminar<https://www.mn.uio.no/math/english/research/groups/risk-stochastics/star-se…> series on Friday, June 26th, from 11:00 to 12:00 (Oslo time). As always, the talk will take place 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<https://uio.zoom.us/j/68891938436>. The speaker is Gonçalo dos Reis (University of Edinburgh) with the talk Title: Simulation of mean-field SDEs: some recent results Abstract: We review two results in the simulation for SDE of McKean-Vlasov type (MV-SDE). The first block of results addresses simulation of MV-SDEs having super-linear growth in the spatial and the interaction component in the drift, and non-constant Lipschitz diffusion coefficient. The 2nd block is far more curious. It addresses the study the weak convergence behaviour of the Leimkuhler--Matthews method, a non-Markovian Euler-type scheme with the same computational cost as the Euler scheme, for the approximation of the stationary distribution of a one-dimensional McKean--Vlasov Stochastic Differential Equation (MV-SDE). The particular class under study is known as mean-field (overdamped) Langevin equations (MFL). We provide weak and strong error results for the scheme in both finite and infinite time. We work under a strong convexity assumption. Based on a careful analysis of the variation processes and the Kolmogorov backward equation for the particle system associated with the MV-SDE, we show that the method attains a higher-order approximation accuracy in the long-time limit (of weak order convergence rate 3/2) than the standard Euler method (of weak order 1). While we use an interacting particle system (IPS) to approximate the MV-SDE, we show the convergence rate is independent of the dimension of the IPS and this includes establishing uniform-in-time decay estimates for moments of the IPS, the Kolmogorov backward equation and their derivatives. The theoretical findings are supported by numerical tests. This presentation is based on the joint work [1], [2]. [1] Chen, X., Dos Reis, G., Stockinger, W. and Wilde, Z., 2025.
