            "description": "<p>We investigate an anisotropic vanishing viscosity limit of the 3D stochastic Navier-Stokes equations posed between two horizontal plates, with Dirichlet no-slip boundary condition. The turbulent viscosity is split into horizontal and vertical directions, each of which approaches zero at a different rate. The underlying Cylindrical Brownian Motion driving our transport-stretching noise is decomposed into horizontal and vertical components, which are scaled by the square root of the respective directional viscosities. We prove that if the ratio of the vertical to horizontal viscosities approaches zero, then there exists a sequence of weak martingale solutions convergent to the strong solution of the deterministic Euler equation on its lifetime of existence. A particular challenge is that the anisotropic scaling ruins the divergence-free property for the spatial correlation functions of the noise.</p>",

            "description": "<p>First-order methods are widely used in optimization and machine learning, and their behavior is often analyzed through the spectrum of worst case convergence rates. Obtaining such guarantees is often difficult and both time consuming and error-prone. Starting with the work of Drori and Teboulle (2014), novel techniques have been used to gain numerical insights, leading to the release of various performance estimation (PE) software. <br>\r\n<br>\r\nIn this talk, I will show how various computer-aided techniques can be used to study first-order optimization methods in a systematic way. From performance estimation problems with automated Lyapunov discovery, to symbolic regression and computer algebra systems, novel tools completely reshape the way we approach theory of optimization. <br>\r\nAs a main example, I will focus on error feedback methods used with compressed communication in distributed optimization. While error feedback has been widely studied, existing theory often provides untight (thus unreliable)  bounds. I will present tight analyses with matching lower bounds that allow a fair comparison between error feedback schemes and standard compressed gradient descent, and help explain when error feedback is useful and when it is not.<br>\r\n<br>\r\nOverall, the talk aims to show how various computer-aided proofs can lead to clearer and more reliable insights into first-order optimization methods.<br>\r\n<br>\r\nBased on :<br>\r\n<a href=\"https://icml.cc/virtual/2026/poster/62713\" target=\"_blank\">A Tight Theory of Error Feedback Algorithms in Distributed Optimization,</a> DB Thomsen, A Taylor, A Dieuleveut<br>\r\nInternational Conference on Machine Learning (ICML 2026)<br>\r\n<a href=\"https://scholar.google.com/citations?view_op=view_citation&amp;hl=fr&amp;user=ge-OinUAAAAJ&amp;sortby=pubdate&amp;citation_for_view=ge-OinUAAAAJ:q3oQSFYPqjQC\" target=\"_blank\">Tight analyses of first-order methods with error feedback</a>, DB Thomsen, A Taylor, A Dieuleveut<br>\r\nAdvances in Neural Information Processing Systems (NeurIPS) (2025).<br>\r\n<a href=\"https://scholar.google.com/citations?view_op=view_citation&amp;hl=fr&amp;user=ge-OinUAAAAJ&amp;sortby=pubdate&amp;citation_for_view=ge-OinUAAAAJ:L8Ckcad2t8MC\" target=\"_blank\">PEPit: computer-assisted worst-case analyses of first-order optimization methods in Python</a><br>\r\nB Goujaud, C Moucer, F Glineur, JM Hendrickx, AB Taylor, A Dieuleveut<br>\r\nMathematical Programming Computation 16 (3), 337-367  (2024)<br>\r\n(eventually - as a detour) <a href=\"https://scholar.google.com/citations?view_op=view_citation&amp;hl=fr&amp;user=ge-OinUAAAAJ&amp;sortby=pubdate&amp;citation_for_view=ge-OinUAAAAJ:wbdj-CoPYUoC\" target=\"_blank\">Provable non-accelerations of the heavy-ball method</a> B Goujaud, A Taylor, A Dieuleveut, Mathematical Programming, 1-59  (2025)<br>\r\n </p>",

The up-to-date program of the summer school can be found at<br>\r\nhttps://numrad.epfl.ch/scientific-program/<br>\r\n<br>\r\nThe school is addressed to young mathematicians (PhD students, early postdoc researchers, and highly motivated master students), and it will consist in lectures delivered by world-wide renowned experts. Participants will have the chance to share their research during a poster session. <br>\r\n<br>\r\nThere are no registration fees, but the number of participants is limited. You can apply to the summer school by submitting the application form by February 13th 2026 at:<br>\r\nhttps://numrad.epfl.ch/registration/<br>\r\nApplicants will be informed of the admission decision by email within three weeks after the application deadline.<br>\r\n<br>\r\nFor more details, please visit:<br>\r\nhttps://numrad.epfl.ch<br>\r\n<br>\r\nThe event is funded by the Bernoulli Center at EPFL, the EDOC EPFL, and by the CSQI Chair.<br>\r\n<br>\r\nLooking forward to seeing you in Lausanne next June!</p>",

A Kakeya set is a compact subset of R^n that contains a unit line segment pointing in every direction.  Kakeya set conjecture asserts that every Kakeya set has Minkowski and  Hausdorff dimension n. We prove this conjecture in R^3 as a consequence of a more general statement about union of tubes. Joint work with Josh Zahl. <br>\r\n<br>\r\n<a href=\"https://candes.su.domains/\">Professor Candès</a> will deliver a talk titled “<strong>What Statistics and AI Offer Each Other?</strong>“, exploring how thinking carefully about AI inputs and outputs yields more powerful, safer AI. By examining several vignettes, we shall answer questions such as: how do we train language models under cost constraints? What happens when we’ve exhausted all available data? If I start a clinical trial using the drug AI thinks is best, will it pan out? How can we ensure high-quality products when AI is used in a larger workflow? That is, how do I know whether AI automated a task correctly? AI powered imputations are beginning to substitute for real data when collection of the latter is difficult, slow, or costly. How then should we leverage machine learning predictions both as a substitute for high-quality data and as a tool for guiding real data collection?<br>\r\n<br>\r\n<a href=\"https://bernoulli.epfl.ch/georges-de-rham/\">Bernoulli Center for Fundamental Studies </a><br>\r\n </p>",

After a fixed number of steps, the left tail has a Gaussian profile under minimal assumptions. Remarkably, a similar phenomenon occurs when we consider a positive random walk on the cone of positive-semidefinite matrices. After a fixed number of steps, the minimum eigenvalue is described by a Gaussian random matrix model.<br>\r\nThis talk introduces a new way to make this intuition rigorous. The methodology addresses an open problem in computational mathematics about sparse random embeddings. The presentation targets a general mathematical audience.<br>\r\nPreprint: <a href=\"https://arxiv.org/abs/2501.16578\" target=\"_blank\">https://arxiv.org/abs/2501.16578</a><br>\r\n<br>\r\n<strong>Please register on the following form : </strong>https://forms.gle/ppXwKo9HmTgFk3rc7",

            "description": "<p>This summer school, organized by seven PhD students from EPFL and ETH Zurich, brings together leading researchers and postgraduate students. Participants will learn modern mathematical and probabilistic methods for linear algebra through lectures by experts in randomized numerical linear algebra. The program also includes networking opportunities with fellow participants, lecturers, and industry representatives.<br>\r\n<br>\r\nThe summer school takes place in a modern hotel in the middle of the historic lakeside town of Murten/Morat. Accommodation, food, and all other costs during the summer school will be covered. All participants are charged a small registration fee.<br>\r\n<br>\r\n<a href=\"http://morat2026.epfl.ch/registration\">Registrations</a> can be made until February 15 and are primarily open to doctoral students from the ETH domain, with limited exceptions for international and master’s students. It is possible to obtain 2 ECTS credits for attending MoRAT.</p>",
