Dear colleagues, this is a gentle reminder of today One World Probability Seminar, details below. Please note the unsual time: the seminar will be held at 17:00 (italian time). You can find the calendar for the upcoming seminars at this link<https://www.owprobability.org/one-world-probability-seminar/future-seminars>. We hope to see many of you online! Luisa and Roger ________________________________ Da: One World Probability <ow.probability(a)gmail.com> Inviato: mercoledì 2 aprile 2025 14:41 A: Luisa Andreis <luisa.andreis(a)polimi.it> Oggetto: Fwd: Next OWPS The next OWPS will be on Wednesday, April 2, from 15:00 to 17:00 UTC time. Note that the UTC time is shifted by one hour (to add to the confusion of those of you in countries that have changed the clock recently). Title, abstract and the zoom link are below the signature and can be found on the website https://www.owprobability.org/one-world-probability-seminar<https://protect-eu.mimecast.com/s/-zGkCWqjZFlpkVlsnEyR_?domain=eur01.safeli…>. ----------------------- Spherical integrals in probability and beyond Colin McSwiggen (Academia Sinica) This mostly expository talk will introduce a number of types of integrals over compact Lie groups that show up constantly in probability and mathematical physics. The analysis of these so-called spherical integrals, in particular their high-dimensional ("large-N") asymptotics, has played a central role in random matrix theory and related subjects over the last 25 years. I'll outline the history of these special functions and describe a number of applications in which they arise, including some original research results with various coauthors. Finally, as a segue to the second lecture by Jon Novak, I'll discuss approaches to large-N analysis. Hypergeometric functions of huge (random) matrices Jonathan Novak (UC San Diego) Hypergeometric functions of matrix arguments are multivariate generalizations of classical hypergeometric functions, and approximating hypergeometric functions of huge matrices is one of the most exciting open problems in high-dimensional analysis. Over the course of the past decade, it has gradually become clear that hypergeometric functions of matrices are discrete analogues of random matrix partition functions. This analogy is clearest for complex matrices, where hypergeometric functions are discrete counterparts of the partition function of the Hermitian one-matrix model with an arbitrary potential, with Schur measure taking on the role of the Gaussian background. Once this is understood, a striking conjecture explicitly describing the asymptotics of all hypergeometric functions emerges. I will explain this conjecture, and outline recent progress towards its solution. https://polimi-it.zoom.us/j/92945513591?pwd=zjtRwpHoO9kRyQuPPj4o186jXrvg1v.1 Meeting ID: 92945513591 Passcode: 131676

Seminar Alexandra Holzinger - Luiss
by Marta Leocata 01 Apr '25

01 Apr '25

Dear all, The Department of Economics and Finance at Luiss University in Rome (https://economiaefinanza.luiss.it <https://economiaefinanza.luiss.it/>) is pleased to announce the following seminar: Speaker: Alexandra Holzinger, Mathematical Institute, University of Oxford Title: Fluctuations around the mean-field limit for attractive Riesz interaction kernels in the moderate regime When: April 3, 14:30 Where: Viale Romania, 32 00197 Rome Meeting room: 405 Abstract: In this talk I will give a short introduction to moderately interacting particle systems and the general notion of fluctuations around the mean-field limit. We will see how a central limit theorem can be shown for moderately interacting particles on the whole space for certain types of interaction potentials. The interaction potential approximates singular attractive potentials of sub-Coulomb type and we can show that the fluctuations become asymptotically Gaussians. The methodology is inspired by the classical work of Oelschläger in the 1980s on fluctuations for the porous-medium equation. To allow for attractive potentials we use a new approach of quantitative mean-field convergence in probability in order to include aggregation effects. Should you be interested, please kindly send me an e-mail. Best wishes, Marta Leocata

Seminars in Statistics at Collegio Carlo Alberto - Sergios AGAPIOU (University of Cyprus)
by Matteo Giordano 28 Mar '25

28 Mar '25

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.google.com/url?q=https://www.carloalberto.org/events/category/s…> Venerdì 04/04/2025, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ 12.00-13.00 Speaker: Sergios AGAPIOU (University of Cyprus) Title: HEAVY-TAILED BAYESIAN NONPARAMETRIC ADAPTATION OVER BESOV SPACES Abstract: We will consider the Bayesian recovery of an unknown function from direct observations polluted by white Gaussian noise, and we will be interested in studying the asymptotic performance of the posterior in the infinitely informative data limit, in terms of rates of contraction. We will be especially interested in priors which are adaptive to the smoothness of the unknown function. In the past decade, certain hierarchical and empirical Bayes procedures based on Gaussian process priors, have been shown to achieve adaptation to spatially homogenous smoothness. However, we have recently shown that Gaussian priors are suboptimal for spatially inhomogeneous unknowns, that is, functions which are smooth in some areas and rough or even discontinuous in other areas of their domain. Such unknowns are abundant in applications such as imaging, and can be modeled using Besov spaces, which generalize (the more widely known) Sobolev and Hölder spaces. In contrast to Gaussian priors, we have shown that (similar) hierarchical and empirical Bayes procedures based on Laplace (series) priors, achieve adaptation to both homogeneously and inhomogeneously smooth functions. All of these procedures involve the tuning of a hyperparameter of the Gaussian or Laplace prior. We will introduce Besov spaces and will recall their minimax theory developed in the mid-late 90’s and has various interesting features. After reviewing the above Bayesian results, we will present a new strategy for adaptation to smoothness based on heavy-tailed priors. Specifically, we will show that adaptive rates of contraction in the minimax sense (up to logarithmic factors) are achieved without tuning of any hyperparameters. This adaptation is achieved for both homogeneously and inhomogeneously smooth unknowns, in particular, we will show that the studied heavy-tailed priors are adaptive over all Besov spaces and for all L^p-losses, for p from 1 up to infinity. Extensive numerical simulations corroborating the theory will be presented as well. This is joint work with Masoumeh Dashti, Tapio Helin, Aimilia Savva and Sven Wang (Laplace priors), and Ismaël Castillo and Paul Egels (heavy-tailed priors) ------------------------------------------------ Sarà possibile il seminario anche in streaming: chiunque volesse collegarsi è pregato di inviare una email entro *mercoledì 02/04/2025* a matteo.giordano(a)unito.it <mailto:matteo.giordano@unito.it> .
