RETTIFICA - Avviso di Seminario Prof. Nicos Georgiou
by luigia.caputo 10 Feb '26

10 Feb '26

Il giorno 11 Febbraio 2026, alle ore 11:30, in aula G, del Dipartimento di Matematica e Applicazioni R. Caccioppoli, il Prof. Nicos Georgiou, School of Mathematical and Physical Sciences, University of Sussex, terrà il seguente seminario: Title: Mean-field limit and parameter estimation for contagion dynamics on higher-order structures. Abstract: Classical models of contagion epidemics have graph based representations where the nodes represent the population and infections occur from an infected individual to a susceptible individual via a network link between them. At the same time, healing mechanisms try to fight the epidemic at node level. The simple descriptions of these representations also underscore their limitations, since the propagation of contagions in complex systems often involves repeated or simultaneous stimuli that individuals receive from their social contacts (such as their work or household). One may mechanistically encode these non-linear effects into contagion models by considering interactions that go beyond simple pairwise connections, by using hypergraphs rather than graphs. In this talk we will see the role higher-order interactions can play in the behaviour of the model when a rigorous mean-field can be obtained. Furthermore, we will discuss some inference techniques for the parameters of the epidemic (rates of infection) when only partial information on the type of infection is available and with only a single realisation of the epidemic curve as a datum. Sarà possibile seguire il seminario anche on line all'indirizzo: Seminario Prof. Nicos Georgiou | Partecipazione alla riunione | Microsoft Teams [1] Cordiali saluti, Luigia Caputo -- Luigia Caputo, PhD Ricercatore Universitario di Probabilità e Statistica Matematica, Dipartimento di Matematica e Applicazioni, Università di Napoli FEDERICO II Via Cintia, 80126, NAPOLI https://www.docenti.unina.it/luigia.caputo Links: ------ [1] https://teams.microsoft.com/meet/31163119321676?p=0yg2ZqOMTtwT5EC1l7

[STAR Seminars] Wed Feb 11 - Rahma Yasmina Moulay Hachemi
by Leonardo Tarquini 05 Feb '26

05 Feb '26

Dear all, Join us for our upcoming talk in the STAR seminar<https://www.mn.uio.no/math/english/research/projects/storm/events/seminars/…> series on Wednesday, February 11th, 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/61970286852>. The speaker is Rahma Yasmina Moulay Hachemi (University of Saida Dr. Moulay Tahar) with the talk: Title: The time-fractional stochastic heat equation driven by time-space white noise Abstract: We study the stochastic time-fractional stochastic heat equation: ∂α/∂tα Y(t, x) = λΔY (t, x) + σ W(t, x); (t, x) ∈ (0,∞) × Rd , (0.1), where d ∈ N = {1, 2, ...} and ∂α/∂tα is the Caputo derivative of order α ∈ (0, 2), and λ > 0 and σ ∈ R are given constants. We consider the equation in the sense of distribution, and we find an explicit expression for the S-valued solution Y (t, x), where S is the space of tempered distributions. Following the terminology of Y. Hu [1], we say that the solution is mild if Y (t, x) ∈ L2(P) for all t, x. It is well-known that in the classical case with α = 1, the solution is mild if and only if the space dimension d = 1. We prove that if α ∈ (1, 2) the solution is mild if d = 1 or d = 2. If α < 1 we prove that the solution is not mild for any d. [1] Hu, Yaozhong (2019): Some recent progress on stochastic heat equations.

Seminario Georgios Athanasopoulos, Martedì 10 Febbraio, Sapienza Università di Roma
by Silvestri, Vittoria 05 Feb '26

05 Feb '26

Segnalo il seguente seminario, che si terrà Martedì prossimo in Sapienza. *Martedì 10 Febbraio, ore 14:00,* Sala di Consiglio, Dipartimento di Matematica, Sapienza Università di Roma *Speaker:* Georgios Athanasopoulos (Università Roma Tre) *Title:* Around the exact solutions of the 2D classical and 1D quantum Ising models. *Abstract:* I will review some recent developments about the 2D classical Ising model focusing on the method of Kac and Ward. In joint work with Daniel Ueltschi, we have extended this method to systems with negative coupling constants. As a consequence, we observe that the Cimasoni--Duminil-Copin--Li equation for the critical temperature, originally proved for general bi-periodic planar lattices with positive couplings, remains valid in a broader setting. Furthermore, I will discuss the possibility of extending this method to study the energy correlations for coupling constants of arbitrary sign. Finally, I will explain how this method can be used to rigorously compute the free energy of the 1D quantum Ising model. ******************************** Vittoria Silvestri Associate Professor Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome ********************************

SLMath SGS-1126 Mathematics for Machine Learning
by Domenico Marinucci 03 Feb '26

03 Feb '26

Care colleghe e cari colleghi segnalo la scuola estiva di Mathematics for Machine Learning, che si terrà all'ICTP di Trieste dal 15 al 26 giugno 2026, sito web: https://indico.ictp.it/event/11148 Alcuni dettagli qui sotto: -------------------------------------------------------------------------------------------- Lecturers: Francesca Mignacco (Princeton University) Andrea Montanari (Stanford University) Course by Andrea Montanari This summer school provides an introduction to theoretical ideas that have been developed with the objective of understanding machine learning methods and their domain of applicability. The focus will be on proof technique and general mathematical tools. 1.Empirical risk minimization and empirical process theory. Objective: Understand how learning is formalized in terms of generalization guarantees, and how the latter emerge from uniform control over suitably restricted function classes. a.Uniform convergence guarantees for learning b.Complexity bounds for neural networks c.Tools: Strong laws of large numbers, concentration of measure, Radamacher complexity. 2.Generalization in the linear regime. Objective: Understand how and when good generalization can be achieved while violating the (naive) assumptions of uniform convergence. In particular, characterize the generalization error of kernel and random features methods. a.Interpolation and benign overfitting b.Kernel methods c.Random features and neural tangent models d.Tools: Random matrix theory 3.Feature learning in large networks. Objective: Analysis of simple neural network models (two-layer network) outside the linear/neural tangent regime. a.Mean field theory b.Multi-index models c.Tools: Propagation of chaos, Wasserstein gradient flows. 4.Sampling and generative methods. Objective: Describe and justify mathematically architecture for generative models. Presents correctness guarantees, as well as limits in some simple settings. a.Autoregressive models, diffusion models, probability flows. b.Sampling guarantees under assumptions on the score estimation. c.Impossibility results. d.Tools: Stochastic localization, functional inequalities, computation-information gaps. Course by Francesca Mignacco The lectures will present an overview on the statistical physics approach to high-dimensional learning problems. The main concepts and methods from mean-field theory of disordered systems will be introduced through prototypical examples that are amenable to analytic characterization. More precisely, the course syllabus will be as follows: 1. Motivation and background. Objective: Introduce the statistical physics perspective on high-dimensional learning problems and the main concepts and settings covered throughout the course. (a) The jargon of statistical physics: thermodynamic limit, order parameters, typical-case scenario. (b) The perceptron. (c) The teacher-student paradigm. 2. Statics of learning. Objective: Understand the Bayes-learning framework and how to apply it to study the impact of data structure and architectural bias on the performance. (a) Generalization error in the perceptron: Bayes-optimal performance vs empirical risk minimization. Introduction to the replica method. (b) Memory capacity: from random points to neural manifolds. Applications to deep learning and neuroscience. (c) Models of data structure. (d) Deep linear networks and back-propagating kernel renormalization 3. Dynamics of learning. Objective: Understand how to derive effective low-dimensional descriptions of the learning dynamics and apply them to study commonly-used training algorithms such as stochastic gradient descent. (a) Online learning in two-layer neural networks. (b) Batch learning: dynamical mean-field theory, cavity method and path integral formulation. Participants: The school can be of interest for a very broad range of students basically from all areas of Pure and Applied Mathematics. Indeed, on one hand the topics of the school are specially addressed to those that are working in disciplines directly involved with Machine Learning (such as mathematical statistics, probability, information theory, numerical analysis, statistical mechanics); on the other hand, the lectures are developed starting from a limited requested background in these specific disciplines, so that students with good mathematical foundations in other areas could attend as well. Hence this school could provide the occasion for students with a different background to get into an exciting new area of research, either to find new connections at the theoretical level or to gain further skills which are on extremely high-demand at every level. The school may also be suitable for students who are not enrolled in a mathematical PhD but are working in related areas, such as statistics, computer science, engineering. Organizing committee: Claudio Arezzo (ICTP), Jean Barbier (ICTP), Filippo Bracci (Roma Tor Vergata and INdAM), Domenico Marinucci (Rome Tor Vergata and INdAM), Cristina Trombetti (Napoli Federico II and INdAM), ---------------------------------------------------------------------------------------------------------------- Grazie per l'attenzione, Domenico Marinucci -- @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ Domenico Marinucci Dipartimento di Matematica Università di Roma Tor Vergata https://sites.google.com/view/domenicomarinucci @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

SPASS seminar
by Francesco Grotto 02 Feb '26

02 Feb '26

Dear Colleagues, We would like to invite you to the following SPASS seminar, *Current trends and challenges in atmospheric CO2 monitoring* by Carina Geldhauser (ETH) on Tuesday 3.2.2026 at 14:00 CET in Aula Riunioni, Dipartimento di Matematica, Pisa. Best, F. Grotto on behalf of the organizers Abstract: In this era of rapid climate change, the precise monitoring of carbon dioxide emissions has become a critical task. We review current efforts to model the spatial propagation of CO2 concentration levels. We highlight the limitations of current results from isolated megacities for European setting: In Europe, the spatiotemporal distribution of CO2 is heavily influenced by atmospheric dynamics and terrestrial biospheric fluxes, hindering a succesful application of traditional modelling approaches. Hence, we prototyped the application of machine learning models to predict ground-level CO2 from satellite measurements. Our results show the effectiveness of integrating diverse data sources in capturing local emission patterns, highlighting the value of high-resolution atmospheric transport models.

Alberto Chiarini e Sonia Mazzucchi %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Lorenzo Zambotti e Alberto Bonicelli (Sorbonne Université) TITOLO: La rivoluzione dell’analisi stocastica « pathwise ». RIASSUNTO: L’analisi stocastica, creata da Itô negli anni 40, ha dominato la teoria dei processi stocastici fino alla fine del XX secolo e oltre. Negli ultimi 25 anni una serie di nuove idee ha arricchito questa teoria e permesso dei progressi spettacolari, in particolare nello studio delle equazioni stocastiche alle derivate parziali. Le tecniche principali in questa area di ricerca sono i rough paths, il sewing lemma, le strutture di regolarità e le distribuzioni para-controllate. In questo seminario vogliamo presentare le idee principali di questo settore, in particolare la nozione di integrazione stocastica « pathwise », il teorema di ricostruzione e le espansioni di Taylor generalizzate.

SEMINAR: Ester Mariucci @Luiss - 12 feb
by Matteo Iacopini 30 Jan '26

30 Jan '26

Dear all, On Thursday, 12th February, at 12:00 in room A304b, the Department of AI, Data and Decision Sciences of Luiss University of Rome will host a seminar by Ester Mariucci (Université Paris-Saclay) Title: "Understanding the Small Jumps of Lévy Processes: Approximations and Nonparametric Estimation” Abstract: There is a rich literature on approximations of the small jumps of a Lévy process, with a particular focus on Gaussian approximations. These approximations are often used to simplify analysis, but their validity depends critically on the observation scheme, in particular whether the data are collected at high or low frequency. In many situations, the Gaussian approximation may not be appropriate, and a more precise understanding of the law of small jumps is necessary. In this talk, we will discuss two complementary approaches. First, we explore approximations of the small jumps and provide quantitative control of their accuracy using distances such as the Wasserstein distance and total variation. Second, we investigate nonparametric density estimation of the small jumps based on discrete observations of a single trajectory. Estimating this density allows us to better understand the underlying distribution of small jumps. We present results for both low-frequency and high-frequency observation settings. In the low-frequency case, assuming that the Lévy density associated with large jumps is known, a spectral estimator exploiting the deconvolution structure achieves minimax parametric rates of convergence with respect to the integrated L2 loss, up to a logarithmic factor. In the high-frequency case, the assumption on the knowledge of the Lévy measure of large jumps can be relaxed; the rate of convergence then depends on the sampling scheme and on the behavior of the Lévy measure near zero, and is minimax up to a logarithmic factor. We also propose an adaptive penalized procedure to select the cutoff parameter. These results are further extended to include the case where a Brownian component is present. Finally, we illustrate our findings through extensive simulations. Anyone interested in attending is welcome; just email me for logistical purposes. Hoping to meet you there!

Seminar Chiarini at Tor Vergata, February 2
by Michele Salvi 29 Jan '26

29 Jan '26

Dear all, On Monday, February 2nd, at 14h00 in Aula Dal Passo in the Math Department of the University of Rome Tor Vergata, RoMaDS (https://www.mat.uniroma2.it/~rds/events.php) will host Alberto Chiarini (Università di Padova) with the seminar "Fluctuations of the Simple Exclusion Process on Point Processes” Abstract: The simple exclusion process is one of the most prominent models of interacting particle systems. In this seminar, we consider a resistor network whose nodes are sampled according to a simple point process on R^d and are connected by certain conductances. On top of this resistor network, particles move according to random walks with the rule that there is at most one particle per site. Under soft assumptions on the point process measure and conductances, which include ergodicity, stationarity and certain moment conditions, it is known that the empirical density of particles converges for almost all realisation of the environment to the solution of an heat equation with a certain homogenised diffusivity. In this talk, we examine its equilibrium fluctuations. For d≥3, under the same assumptions that ensure the hydrodynamical limit, we show that the empirical density fluctuation field converges for almost all realisation of the environment, in the sense of finite-dimensional distributions, to a generalised Ornstein-Uhlenbeck process. For d=2, if we require some additional regularity on the environment to have Hölder regularity estimates for solutions to parabolic problems, we can show that the same conclusion holds. We encourage in-person partecipation.

Open Ph.D. position at the University of Luxembourg
by Giovanni Peccati 27 Jan '26

27 Jan '26

Dear Colleagues, The *Department of Mathematics* of the *University of Luxembourg* (*DMATH*) is seeking an excellent candidate for a *PhD position* in the area of *Mathematical Statistics*, with an expected starting date in *2026*. *-----------------------* *Supervisor:* Prof. *Yannick Baraud* (https://math.uni.lu/baraud/Home.html) *PhD topic:* *Classical Bayesian methods can be used to construct estimators with good statistical properties. For example, when the data are i.i.d. and come from a distribution belonging to a parameterised model with a suitable prior distribution, numerous studies show that the posterior distribution is concentrated around the parameter associated with the distribution of the data.* *Despite their popularity, these methods nevertheless have certain limitations. In particular, when the data-generating distribution does not belong to the family of distributions chosen as the model, the estimators obtained may be of poor quality, even when the model provides a good approximation of the truth. This situation can arise, for example, when the sample contains a few outliers due to measurement or transcription errors. More generally, it occurs when the statistical model is only a simplification of reality, which is often the case in practice. The statistical method is then said to suffer from a lack of robustness as it produces unstable estimators that are sensitive to small deviations from the assumed model.* *In this PhD proposal, we offer the opportunity to study a robust alternative to classical Bayesian methods. This is a recent approach, the main properties of which were established in [1] in the context of density estimation. The aim of this PhD proposal is to understand the mathematics behind these new techniques and to extend it beyond density estimation. * *A candidate for this position must have a strong background in analysis, probability and mathematical statistics as well as a taste for theory. * [1] Y. Baraud. From robust tests to Bayes-like posterior distributions. Probab.

A well-known result (proved under various assumptions in several references) concerns the convergence in distribution of the network output, in the infinite-width limit, to a centered Gaussian process with i.i.d. components (with the depth $L$ kept fixed). I will present some large deviation results describing a collapse of the network output (which, as expected, converges to the zero vector) when it is multiplied by a scaling factor tending to zero; see [1], where moderate deviations are also studied. In the final part, I will briefly outline some results in a very recent work (see [2]) concerning the deep limit (that is, as $L\to\infty$) for a generic component of the Gaussian process mentioned above.

[STAR Seminars] Wed Jan 21 - Susanna Dehò
by Leonardo Tarquini 21 Jan '26

21 Jan '26

Dear all, Join us for our upcoming talk in the STAR seminar<https://www.mn.uio.no/math/english/research/projects/storm/events/seminars/…> series on Wednesday, January 21st, 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/67027975721>. The speaker is Susanna Dehò (University of Milano "La Statale") with the talk: Title: Symmetries of SDEs: from invariance properties to integration by parts formulas Abstract: The study of symmetries in differential equations, pioneered by Sophus Lie, constitutes a fundamental geometric approach to understand the invariance properties governing a dynamical system. By identifying the groups of transformations that preserve the equation’s structure, this framework provides systematic tools for order reduction, the construction of exact solutions, and the simplification of complex problems. Although symmetry analysis stands as a classical pillar for deterministic differential equations (ODEs and PDEs), supported by extensive literature, its extension to Stochastic Differential Equations (SDEs) represents a relatively recent field of research. Recent literature has also highlighted significant connections with the symmetries of the associated Fokker-Planck or Kolmogorov equations. Furthermore, the application of Lie symmetry theory to SDEs enables the derivation of integration by parts formulas inspired by Bismut’s variational approach to Malliavin calculus, with notable applications to the analysis of the law and regularity of the processes, as well as to the development of a stochastic calculus of variations. In this talk, we will discuss various notions of symmetry for SDEs, highlighting their connections to established invariance properties of well-known stochastic models and the symmetries of Kolmogorov PDEs. We will analyze how a geometric approach, inspired by Lie’s deterministic framework, enables the development of powerful computational tools for symmetry calculation. Subsequently, we will demonstrate how applying this geometric theory allows for the constructive derivation of an integration by parts formula for SDEs, rooted in Bismut’s approach. Finally, we will show how this integration by parts formula acts as a generating identity for well-known probability formulas, and discuss its connections to Stein’s identities. This contribution is based on a joint work with F.C. De Vecchi, P. Morando and S. Ugolini. Susanna Dehò, Francesco C. De Vecchi, Paola Morando, and Stefania Ugolini. Random rotational invariance of integration by parts formulas within a Bismut-type approach. Journal of Mathematical Physics: in print, 2025. We are looking forward to seeing you!

Our next speaker is Louis Sharrock<https://louissharrock.github.io/> <https://louissharrock.github.io/> (University College London) who will talk about "Sequential Neural Score Estimation: Likelihood-free inference with conditional score base diffusion models" on Thursday the 29th January at 11am UK time, with an abstract reported below. The talk will be streamed on the OWABI MS Team channel General | OWABI Seminar: One World Approximate Bayesian Inference Seminar | Microsoft Teams<https://teams.microsoft.com/l/team/19%3AdhZ_4e_XLNJzCXPAMzTvT6BZ5KShEETkd_w…>, at the link below Join: https://teams.microsoft.com/meet/38899039621449?p=nCtiqu8zYnZNL2LGR8 Meeting ID: 388 990 396 214 49 Passcode: f3Dh22XL We are looking forward to seeing you at the next OWABI seminar, Best, Massimiliano on the behalf of the OWABI seminar organisers Speaker: Louis Sharrock (University College London) Title: Sequential Neural Score Estimation: Likelihood-free inference with conditional score base diffusion models Abstract: We introduce Sequential Neural Posterior Score Estimation (SNPSE), a score-based method for Bayesian inference in simulator-based models. Our method, inspired by the remarkable success of score-based methods in generative modelling, leverages conditional score-based diffusion models to generate samples from the posterior distribution of interest. The model is trained using an objective function which directly estimates the score of the posterior. We embed the model into a sequential training procedure, which guides simulations using the current approximation of the posterior at the observation of interest, thereby reducing the simulation cost. We also introduce several alternative sequential approaches, and discuss their relative merits. We then validate our method, as well as its amortised, non-sequential, variant on several numerical examples, demonstrating comparable or superior performance to existing state-of-the-art methods such as Sequential Neural Posterior Estimation (SNPE). Keywords: diffusion models, simulation based inference, sequential methods. Reference: L. Sharrock, J. Simons, S. Liu, M.

Alberto Chiarini e Sonia Mazzucchi %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Lorenzo Zambotti e Alberto Bonicelli (Sorbonne Université) TITOLO: La rivoluzione dell’analisi stocastica « pathwise ». RIASSUNTO: L’analisi stocastica, creata da Itô negli anni 40, ha dominato la teoria dei processi stocastici fino alla fine del XX secolo e oltre. Negli ultimi 25 anni una serie di nuove idee ha arricchito questa teoria e permesso dei progressi spettacolari, in particolare nello studio delle equazioni stocastiche alle derivate parziali. Le tecniche principali in questa area di ricerca sono i rough paths, il sewing lemma, le strutture di regolarità e le distribuzioni para-controllate. In questo seminario vogliamo presentare le idee principali di questo settore, in particolare la nozione di integrazione stocastica « pathwise », il teorema di ricostruzione e le espansioni di Taylor generalizzate.

Dear Colleagues, We would like to invite you to the following SPASS seminars, *Some results on the Kraichnan model* by Umberto Pappalettera (Universität Basel) on Tuesday 20.1.2026 at 14:00 CET in Aula Magna, Dipartimento di Matematica, UNIPI. Online participants may join the seminar at https://meet.google.com/ajh-zrxc-wds Best, F. Butori on behalf of the organizers https://sites.google.com/unipi.it/spass ------------------- Abstract: We discuss a number of properties of ``turbulent'' solutions to the Kraichnan model constructed by Le Jan and Raimond in [Ann. Probab. 30(2): 826-873, 2002]. We cover the full range of compressibility ratios giving spontaneous stochasticity of particle trajectories. More specifically, we prove generic anomalous dissipation of the mean energy and fractional Sobolev regularity of solutions, for every square-integrable initial datum. The proof of the latter is obtained as a consequence of a new sharp regularity result for the degenerate parabolic PDE satisfied by the associated two-point self-correlation function, which is of independent interest.

ABS (Applied Bayesian Statistics) school on "Interpretable Bayesian Learning,for Physical and Engineering Sciences" in Como, Italy (July 6-10, 2026)
by Fabrizio Ruggeri 15 Jan '26

15 Jan '26

Dear all, We are glad to inform you that ABS26, the next Applied Bayesian Statistics school, running since 2004, will be held in the city of Como (Italy), along the Lake Como shoreline at the beautiful Villa del Grumello, on July 6-10, 2026. The school is organised by CNR IMATI (Institute of Applied Mathematics and Information Technologies at the Italian National Research Council in Milano), in cooperation with Fondazione Alessandro Volta. The topic will be *Interpretable Bayesian Learning for Physical and Engineering Sciences.* The lecturer will be Prof. *Simon Mak *(Department of Statistical Science, Duke University), a leading expert in integrating domain knowledge (e.g., scientific theories, mechanistic models, guiding principles) as prior information for cost-efficient statistical inference, prediction, and decision-making., with the support of* Yen-Chun Liu* (Department of Statistical Science, Duke University), a brilliant PhD student of Prof. Mak, specializing in Bayesian optimization, Gaussian processes, and reinforcement learning. If interested, you can register on the school website: *https://abs26.imati.cnr.it/* We currently only accept payments by bank transfer, but credit cards will be accepted as soon as possible. As in the past, there will be a combination of theoretical and practical sessions, along with presentations by participants on their work (past, present, and future) related to the school's topic. OUTLINE: This course investigates the rising topic of interpretable statistical learning, motivated by timely needs from modern scientific and engineering applications. For such applications, state-of-the-art machine learning methods often yield analyses that are uninterpretable to scientists, which greatly obfuscates scientific findings and decision-making. Interpretable Bayesian learning provides an elegant and effective solution by embedding scientific principles (e.g., boundary conditions, mechanistic equations) within its prior specification. In this course, we will cover a broad spectrum of interpretable Bayesian learning methods (with theory and algorithms), providing a cohesive roadmap for this recent and rapidly-evolving area of study. This will be complemented by practical case studies from ongoing projects in particle physics, mechanical engineering, and bioengineering. Emphasis will be made on novel directions for research in this promising area. Topics will cover * Fundamentals of Gaussian process (GP) surrogate modeling: prediction, parameter inference, experimental design * Decision-making with GP surrogates: Bayesian optimization, active learning, Bayesian inverse problems * Markov Chain Monte Carlo (MCMC) methods * Boundary-informed GP modeling * Shape-constrained (e.g., monotone, isotonic, convex) GP modeling * Mechanistic GP modeling * Physics-integrated neural networks, its Bayesian variants and recent developments * Dynamical system recovery: SINDy, Bayesian SINDy, and recent developments We hope you will be interested in the school and we would like to meet you in Como. We invite you also to share the information with people potentially interested.

Seminar by H. Vanneuville at Milano-Bicocca (Thu 22 Jan, 11:00, Room U9-05)
by Francesco Caravenna 15 Jan '26

15 Jan '26

I am pleased to announce the following seminar: Hugo Vanneuville (Université Grenoble Alpes) A new proof of exponential decay in percolation Thursday 22 January at 11:00 Room U9-05 (Building U9, Viale dell'Innovazione 10, Milan) An abstract follows below. All interested participants are welcome. Best regards, Francesco Caravenna %%%%%%%%%%%%%%%%%%%%%%%%%% Abstract. Bernoulli percolation of parameter p on Z^d is defined by keeping each edge of Z^d with probability p, independently of the other edges. The exponential decay theorem - proven in 1987 by Menshikov and independently by Aizenman and Barsky - can be stated as follows: If the cardinality of the cluster of 0 is a.s. finite at some parameter p, then it has an exponential moment at every parameter q<p. I like to state this theorem this way because it illustrates the fact that "decreasing p infinitesimally has a regularising effect on the clusters". The goal of this talk is to discuss this theorem and to propose a new proof. Contrary to the other proofs, we do not rely on differential inequalities but rather on stochastic comparisons. %%%%%%%%%%%%%%%%%%%%%%%%%% -- __________________________________ Francesco Caravenna Dipartimento di Matematica e Applicazioni Università degli Studi di Milano-Bicocca https://fcaraven.github.io/ __________________________________

Seminar Stecconi at Tor Vergata, January 19
by Michele Salvi 15 Jan '26

15 Jan '26

Dear all, On Monday, January 19th, at 14h00 in Aula Dal Passo of Tor Vergata Math Department, RoMaDS (https://www.mat.uniroma2.it/~rds/events.php) will host Michele Stecconi (University of Luxembourg) with the seminar "Universal cancellations in Uniform Random Waves” Abstract: I will present the model of "Uniform Random Waves", obtained by dividing a Gaussian random wave by its L2-norm, on the sphere and other Riemannian manifolds. This choice has deep motivations, although the Gaussian case predominates in the existing literature. I will compare the analysis of these two classes of random fields, focusing on (Wiener) chaos decomposition of geometric functionals and on new surprising (Berry) cancellation phenomena that arise in the uniform setting. Based on the homonymous paper, with L. Gass, D. Marinucci, G. Peccati, F. Pistolato. We encourage in-person partecipation.

14 Jan '26

Dear Colleagues, We would like to invite you to the following SPASS seminar (joint organised by UniPi, SNS, UniFi and UniSi): A Limit Theorem for the Total Progeny Distribution of Multitype Branching Processes by Ivan Kryven (Utrecht University). The seminar will take place in person on Friday 23rd January at 10:00 in Aula Tricerri, Department of Mathematics and Computer Science, University of Florence. It will be also streamed online here: https://meet.google.com/boc-aphg-bbk On behalf of the organisers, Elia Bisi ------------------- Abstract: Multitype branching processes model random trees whose vertices carry types, with each vertex producing offspring according to a type‑dependent multivariate distribution. In this talk, I will present a limit theorem describing the behavior of such processes in the noncritical regime. Specifically, we show that the relative frequencies of the different types in any finite realization converge to a deterministic vector, and that the distribution of the total progeny exhibits exponential decay. These results require only that all moments of the offspring distribution exist. The proof combines several analytic tools, including the Lagrange–Good and arborescent Lagrange inversion formulas, a measure‑tilting argument, and a local limit theorem. I will also discuss applications to models such as random graphs and multi‑component coagulation processes. Joint work with Jochem Hoogendijk and Rik Versendaal. ————————— Elia Bisi Assistant Professor (RTT) University of Florence Department of Mathematics & Computer Science Personal homepage Florence Probability group

Dr. Anna Gallo's seminar at University of Milano-Bicocca.
by Giorgio Rizzini 14 Jan '26

14 Jan '26

Dear all, we are pleased to announce the following seminar by Dr. Anna Gallo (IMT School for Advanced Studies Lucca) on *Thursday, January 15th 2026,* starting at 11:00 in room 4057, the Department of Statistics and Quantitative Methods, University of Milano-Bicocca (Milan): *Rethinking balance theory: a probabilistic approach to the study of signed networks* *Abstract:* Networks provide a powerful language to model interacting systems by representing their units as nodes and the interactions between them as links. Interactions can be connotated in several ways, such as binary/weighted, undirected/directed, etc. In the present talk we focus on the positive/negative connotation- modelling trust/distrust, alliance/enmity, friendship/conflict, etc. - by considering the so-called signed networks. Rooted in balance theory, a psychological framework that has been proposed to model human relationships, the study of signed networks has found application in fields as different as biology, ecology, economics. Here we approach it from the perspective of statistical physics, by extending the framework of Exponential Random Graph Models to the class of binary, un/directed, signed networks and employing it to assess the significance of frustrated patterns in biological, economic and social networks. The degree of balance critically depends on i) the considered system and ii) the employed benchmark: while social networks align with balance theory - with heterogeneous null models supporting its strong version and homogeneous null models supporting its weak version, biological networks often exhibit a pronounced level of frustration. For what concerns binary, directed networks, instead, we explore the relationship between frustration and reciprocity and suggest an alternative interpretation of balance in the light of directionality. Finally, we investigate signed structures at the mesoscopic scale by evaluating the tendency of a configuration to be either `traditionally' or `relaxedly' balanced. For further information, please write to *rosanna.grassi(a)unimib.it <rosanna.grassi(a)unimib.it>* Best regards.

Dear all, Join us for our upcoming talk in the STAR seminar<https://www.mn.uio.no/math/english/research/projects/storm/events/seminars/…> series on Wednesday, January 14th, 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/67027975721>. The speaker is Rahma Yasmina Moulay Hachemi (University of Saida Dr. Moulay Tahar) with the talk: Title: The stochastic heat inclusion with fractional time derivative driven by time-space Brownian white noise Abstract: We study a time-fractional stochastic heat inclusion driven by additive time-space Brownian noise given by: ∂^α/∂t^α Y (t, x) ∈ λ∆Y (t, x) + G(t, x, Y (t, x)) + σW (t, x); (t, x) ∈ (0, ∞) × R^d. Here d ∈ N = {1, 2, ...} is the space dimension, x ∈ R^d denotes a point in space, t ≥ 0 denotes the time. Here d ∈ N = {1, 2, ...} is the space dimension, x ∈ R^d denotes a point in space, t ≥ 0 denotes the time. The fractional time derivative is interpreted as the Caputo derivative of order α ∈ (0, 2). We show the following: a) If a solution exists, then it is a fixed point of a specific set-valued map. b) Conversely, any fixed point of this map is a solution of the heat inclusion. We are looking forward to seeing you! Best regards, Giulia, Leonardo and Pere

SPASS seminar: Pierfrancesco Beneventano
by Marco Romito 09 Jan '26

09 Jan '26

Dear Colleagues, We would like to invite you to the following SPASS seminars, *Edge of Stochastic Stability: SGD does not train neural networks as you expect it* by Pierfrancesco Beneventano (MIT) on Tuesday 13.1.2026 at 14:00 CET in Saletta Riunioni, Dipartimento di Matematica, UNIPI. A link for online participants will be shared on the website https://sites.google.com/unipi.it/spass Best, M. Romito on behalf of the organizers ------------------- Abstract: Recent findings demonstrate that when training neural networks using full-batch (deterministic) gradient descent with step size η, the largest eigenvalue λ of the Hessian consistently stabilizes around 2/η. These results are surprising and carry significant implications for convergence and generalization. This, however, is not the case for mini-batch optimization algorithms, limiting the broader applicability of the consequences of these findings. We show that mini-batch Stochastic Gradient Descent (SGD) trains in a different regime, which we term Edge of Stochastic Stability (EoSS). In this regime, what stabilizes at 2/η is Batch Sharpness: the expected directional curvature of mini-batch Hessians along their corresponding stochastic gradients. As a consequence, λ---which is generally smaller than Batch Sharpness---is suppressed, aligning with the long-standing empirical observation that smaller batches and larger step sizes favor flatter minima. We further discuss implications for mathematical modeling of SGD trajectories.

Seminari Filippo De Feo e Mattia Martini - Politecnico di Milano - 8 Gennaio 2026
by Luca Scarpa 07 Jan '26

07 Jan '26

Si ricordano i seguenti 2 seminari a tutti gli interessati. SEMINARIO 1: Giovedì 8 Gennaio 2026, ore 11:00. Aula Seminari III Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Filippo De Feo, Technische Universität Berlin. Title: Stochastic Optimal Control of Interacting Particle Systems in Hilbert Spaces and Applications in Economics. Abstract: Optimal control of interacting particles governed by stochastic evolution equations in Hilbert spaces is an open area of research. Such systems naturally arise in formulations where each particle is modeled by stochastic partial differential equations, path-dependent stochastic differential equations (such as stochastic delay differential equations or stochastic Volterra integral equations), or partially observed stochastic systems. In this talk we present a limiting theory as the number of particles tends to infinity. We apply the developed theory to problems arising in economics where the particles are modeled by stochastic partial differential equations and stochastic delay differential equations. The talks is based on [F. de Feo, F. Gozzi, A. Swiech, L. Wessels, Stochastic Optimal Control of Interacting Particle Systems in Hilbert Spaces and Applications, arXiv preprint arXiv:2511.21646] Link Zoom: https://polimi-it.zoom.us/j/92373976166?pwd=pvQAMGRkAnZ6WLaEXawDkGmbxa61VV.1 Link Seminario Polimi: https://www.mate.polimi.it/eventi/?id=2663&sezione_di_ricerca=probstat&stri… SEMINARIO 2: Giovedì 8 Gennaio 2026, ore 11:45. Aula Seminari III Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Mattia Martini, École polytechnique, Centre de Mathématiques Appliquées, Palaiseau. Title: Regularisation in mean field models via infinite dimensional diffusion. Abstract: This talk aims to show how randomizing the dynamics in mean field models can help regularize the associated partial differential equations on the space of probability measures. A key challenge in this approach lies in constructing a suitable notion of noise on the space of probability measures. To this end, we rely on the Dirichlet–Ferguson diffusion process, as studied by Dello Schiavo [AOP 22]. We first examine the effect of this noise on a system of uncontrolled interacting particles and show that it induces a regularizing effect at the level of the corresponding backward Kolmogorov equation. We then analyze a mean field control problem driven by this noise and prove that the associated Hamilton–Jacobi equation admits a unique solution in an appropriate functional space, even when the coefficients have limited regularity. The talk is based on a joint work with F. Delarue (Nice) and G. Sodini (Vienna).

seminario Felix Liebrich in Bicocca
by Fabio Bellini 07 Jan '26

07 Jan '26

Il giorno lunedì 12 gennaio alle ore 17 presso la aula seminari 4096 al quarto piano dell'edificio U7 della Università di Milano-Bicocca, il dott. Felix-Benedikt Liebrich della Università di Amsterdam terrà un seminario dal titolo Lambda-quantiles: A closer look at the new kid on the block Abstract: Lambda-VaR has initially been suggested by Frittelli et al. (2014) as a generalisation of classical Value-at-Risk. Recent years have seen a surge in work on these functionals (or slightly more generally: on Lambda-quantiles), both in financial and insurance applications and from a decision-theoretic perspective. This talk focuses on Lambda-quantiles of univariate probability distributions which generalise classical quantiles by replacing the defining constant threshold in the unit interval with a function Lambda mapping the real line to the unit interval. Working under minimal assumptions, we analyse how the choice of Lambda determines mathematical properties of the resulting functional. In particular, we examine aggregation behaviour, continuity, identifiability of the functional parameter Lambda, and the preservation of finer properties of classical quantiles such as ordinal covariance. We conclude by discussing interpretational issues in financial applications. Based on joint work with Fabio Bellini. Tutti gli interessati sono invitati a partecipare.

Seminario Daniela Witten presso Politecnico di Milano
by Laura Maria Sangalli 07 Jan '26

07 Jan '26

Si avvisa che domani, 08/01/2026, alle ore 14:30 presso il Politecnico di Milano, Dipartimento di Matematica, Aula Saleri, nell’ambito delle attività del MOX, si svolgerà il seguente seminario: Daniela Witten Università di Washington Titolo: Data thinning and beyond Abstract: Contemporary data analysis pipelines often involve the use and reuse of data. For instance, a scientist may explore a dataset to select an interesting hypothesis, and then wish to test this hypothesis with the same data. From a statistical perspective, this double use of data is highly problematic: it induces dependence between the hypothesis generation and testing stages, which complicates inference. Failure to account for this dependence renders classical inference techniques invalid. I will present "data thinning", a set of strategies for obtaining independent training and test sets so that the former can be used to select a hypothesis, and the latter to test it. Data thinning enables valid selective inference in settings for which no solutions were previously available. However, it is also restrictive, in the sense that it requires strong distributional assumptions. Therefore, I will also present strategies inspired by data thinning that enable valid post-selection inference without such assumptions. Il link per seguire il seminario online sarà reso disponibile pochi minuti prima dell’avvio del seminario al seguente indirizzo https://mox.polimi.it/mox-colloquia-seminars-list/mox-seminars/?id_evento=2… Tutti gli interessati sono invitati a partecipare.

Seminari Filippo De Feo e Mattia Martini - Politecnico di Milano - 8 Gennaio 2026
by Luca Scarpa 20 Dec '25

20 Dec '25

Si segnalano i seguenti 2 seminari a tutti gli interessati. SEMINARIO 1: Giovedì 8 Gennaio 2026, ore 11:00. Aula Seminari III Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Filippo De Feo, Technische Universität Berlin. Title: Stochastic Optimal Control of Interacting Particle Systems in Hilbert Spaces and Applications in Economics. Abstract: Optimal control of interacting particles governed by stochastic evolution equations in Hilbert spaces is an open area of research. Such systems naturally arise in formulations where each particle is modeled by stochastic partial differential equations, path-dependent stochastic differential equations (such as stochastic delay differential equations or stochastic Volterra integral equations), or partially observed stochastic systems. In this talk we present a limiting theory as the number of particles tends to infinity. We apply the developed theory to problems arising in economics where the particles are modeled by stochastic partial differential equations and stochastic delay differential equations. The talks is based on [F. de Feo, F. Gozzi, A. Swiech, L. Wessels, Stochastic Optimal Control of Interacting Particle Systems in Hilbert Spaces and Applications, arXiv preprint arXiv:2511.21646] Link Zoom: https://polimi-it.zoom.us/j/92373976166?pwd=pvQAMGRkAnZ6WLaEXawDkGmbxa61VV.1 Link Seminario Polimi: https://www.mate.polimi.it/eventi/?id=2663&sezione_di_ricerca=probstat&stri… SEMINARIO 2: Giovedì 8 Gennaio 2026, ore 11:45. Aula Seminari III Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Mattia Martini, École polytechnique, Centre de Mathématiques Appliquées, Palaiseau. Title: Regularisation in mean field models via infinite dimensional diffusion. Abstract: This talk aims to show how randomizing the dynamics in mean field models can help regularize the associated partial differential equations on the space of probability measures. A key challenge in this approach lies in constructing a suitable notion of noise on the space of probability measures. To this end, we rely on the Dirichlet–Ferguson diffusion process, as studied by Dello Schiavo [AOP 22]. We first examine the effect of this noise on a system of uncontrolled interacting particles and show that it induces a regularizing effect at the level of the corresponding backward Kolmogorov equation. We then analyze a mean field control problem driven by this noise and prove that the associated Hamilton–Jacobi equation admits a unique solution in an appropriate functional space, even when the coefficients have limited regularity. The talk is based on a joint work with F. Delarue (Nice) and G. Sodini (Vienna).

Next POPS talk 17.12.: Giulia Sebastiani "From Parisi to Boltzmann: via GREM and TAP"
by Jonas Köppl 15 Dec '25

15 Dec '25

Dear colleagues, The year is coming to an end and we are excited to announce that our next and final speaker of the year will be Giulia Sebastiani (Universität Bonn) who will be speaking about From Parisi to Boltzmann: via GREM and TAP. on December 17, at 13:30 GMT / 14:30 CET / 15:30 EET, on Teams broadcast with the following link: Link to join teams<https://teams.microsoft.com/l/meetup-join/19%3ameeting_N2Q2NGY2NDEtYWVmNS00…> The talk is scheduled for one hour, allowing time for questions. Additionally, we'll be remaining on the call for a chat afterwards if you'd like to join us. We are looking forward to seeing you. Speaker: Giulia Sebastiani Title: From Parisi to Boltzmann: via GREM and TAP Abstract: Introduced by Derrida in the 80s, the Generalized Random Energy Models (GREM) serve as simplified, abstract models that are completely solvable and have significantly contributed to our comprehension of specific facets within the Parisi theory for mean-field spin glasses. In this talk, after an overview of Parisi’s ultrametric principle for the free energy of the Sherrington-Kirkpatrick (SK) model, we will turn to the alternative approach due to Thouless, Anderson, and Palmer (TAP). The TAP approach provides a representation of the SK free energy as the maximum of a random functional over local magnetizations. A simple reformulation reveals that, when evaluated at its critical points, the TAP free energy becomes a nonlinear functional of empirical measures constructed from local fields. Motivated by this structure, we construct abstract GREM-like models whose Hamiltonians are nonlinear functionals of empirical measures associated with GREM-like variables. For the thermodynamic free energy of these abstract models, dual Parisi-like formulas hold and turn out to be finite-dimensional “collapsed” versions of the underlying infinite-dimensional Gibbs-Boltzmann principles. Crucially, the nonlinearity inherited from the TAP representation generates a correction term (absent in canonical GREM-like models) that substantially reduces the gap between the free energies of such abstract hierarchical models and Parisi’s solution for the SK. Based on joint work with Nicola Kistler and Marius Alexander Schmidt. You can find more information about the talk on our website Postgraduate Online Probability Seminars (pg-prob-sem.github.io)<https://pg-prob-sem.github.io/>. Warm regards, The POPS Team This talk will be broadcast on December 17, at 13:30 GMT / 14:30 CET / 15:30 EET on MS Teams only. Meeting ID: 393 527 089 878 Passcode: dsm7py

However, such data present artifactual sources of variation, also known as covariate effects. Covariate effects can be complex, leading to systematic biases, that if not corrected could lead to unreliable inference. In this talk I will present novel sparse latent factor regression (FR) and multi-study factor regression (MSFR) models to integrate such heterogeneous data. The FR model provide a tool for data exploration via dimensionality reduction and sparse low-rank covariance estimation while correcting for a range of covariate effects. MSFR are extensions of FR that enable us to jointly obtain a covariance structure that models the group-specific covariances in addition to the common component. I will discuss the use of several sparse priors (local and non-local) to learn the dimension of the latent factors. Our approaches provide a flexible methodology for sparse factor regression which is not limited to data with covariate effects. Our models are fitted leveraging novel scalable EM and ECM algorithms as well as Variational Inference methods. I will present several examples, with a focus on bioinformatics applications. We show the usefulness of our methods in two main tasks: as an unsupervised dimension reduction task to give a visual representation of the latent factors of the data; and as a supervised tool to: (i) provide survival predictions leveraging the obtained factors, or (ii) obtain dietary patterns, associating each factor with a measure of overall diet quality related to cardiometabolic disease risk. ———————————————————————— Sarà possibile seguire il seminario anche in streaming: chiunque volesse collegarsi è pregato di inviare una email entro *mercoledì 17/12/2025* a matteo.giordano(a)unito.it <mailto:matteo.giordano@unito.it> Il webinar è organizzato dalla "de Castro" Statistics Initiative (www.carloalberto.org/stats <http://www.carloalberto.org/stats>) in collaborazione con il Collegio Carlo Alberto.

Seminario su "Random flights and anomalous diffusion: A non-Markovian take on Lorentz processes"
by Enrico Scalas 12 Dec '25

12 Dec '25

Buongiorno, vi segnalo un seminario che può essere di interesse. Cordiali saluti, Enrico Scalas -- Seminari di Fisica Matematica Dipartimento di Matematica "G. Castelnuovo" Università di Roma La Sapienza mercoledì 17 dicembre, ore 16:00, aula E Lorenzo Facciaroni (Sapienza Università di Roma) Random Flights and Anomalous Diffusion: A non-Markovian Take on Lorentz Processes Abstract. We study Lorentz processes in two different settings. Both cases are characterized by infinite expectation of the free-flight times, contrary to what happens in the classical Gallavotti-Spohn models. Under a suitable Boltzmann-Grad type scaling limit, they converge to non-Markovian random-flight processes. A further scaling limit yields another non-Markovian process, i.e., a superdiffusion obtained by a suitable time-change of Brownian motion. Furthermore, we obtain the governing equations for our random flights and anomalous diffusion, which represent a non-local counterpart for the linear-Boltzmann and diffusion equations. It turns out that these have the form of fractional kinetic equations in both time and space. To prove such results, we develop a technique based on averaging Feller semigroups. Tutte le persone interessate sono invitate a partecipare. --

Seminario Marco Bagnara - Politecnico di Milano - 15 Dicembre 2025
by Luca Scarpa 04 Dec '25

04 Dec '25

Si segnala il seguente seminario a tutti gli interessati. Lunedì 15 Dicembre 2025, ore 16:00. Aula Seminari III Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Marco Bagnara, Imperial College London. Title: Anomalous Regularization in Kazantsev-Kraichnan Model. Abstract: We investigate a passive vector field which is transported and stretched by a divergence-free Gaussian velocity field, delta-correlated in time and poorly correlated in space (spatially nonsmooth). Although the advection of a scalar field (Kraichnan's passive scalar model) is known to enjoy regularizing properties, the potentially competing stretching term in vector advection may induce singularity formation. We establish that the regularization effect is actually retained in certain regimes. While this is true in any dimension $d\ge 3$, it notably implies a regularization result for linearized 3D Euler equations with stochastic modeling of turbulent velocities, and for the induction equation in magnetohydrodynamic turbulence. The presentation is based on a joint work with Francesco Grotto and Mario Maurelli.

SPASS seminars: Macci and Torrisi - Dec 10th

04 Dec '25

Dear Colleagues, We would like to invite you to the following two**SPASS seminars, by Claudio Macci and Giovanni Torrisi, on Wednesday December 10th 2025, starting at 4PM. A link for online participants will be shared on the website https://sites.google.com/unipi.it/spass Titles and abstract are below. With best regards, Dario Trevisan ---- Wednesday December 10th 2025 at 17:00 CET - Aula Fib N1 (Polo Fibonacci B, Università di Pisa) Speaker:/Claudio Macci/ (Università di Roma Tor Vergata) Title:*Some recent large deviation results on random neural networks * Abstract: In this talk, I consider random neural networks with Gaussian weights and biases. A well-known result (proved under various assumptions in several references) concerns the convergence in distribution of the network output, in the infinite-width limit, to a centered Gaussian process with i.i.d. components (with the depth $L$ kept fixed). I will present some large deviation results describing a collapse of the network output (which, as expected, converges to the zero vector) with a multiplicative scaling tending to zero; see [1], where moderate deviations are also studied. In the final part, I will outline some results (currently in preparation, see [2]) on the deep limit (that is, as $L\to\infty$) for a generic component of the Gaussian process mentioned above. REFERENCES [1] C. Macci, B. Pacchiarotti, G.L. Torrisi. Journal of Applied Probability (2026), in press. [2] S. Di Lillo, C. Macci, B. Pacchiarotti. In preparation. Wednesday December 10th 2025 at 17:00 CET - Aula Fib N1 (Polo Fibonacci B, Università di Pisa) Speaker: /Giovanni Luca Torrisi /(CNR - IAC) Title:*Posterior Bayesian Neural Networks with Dependent and Heavy-Tailed Weights* Abstract: We consider fully connected and feedforward deep neural networks with dependent and possibly heavy-tailed weights. These networks have been introduced to alleviate the drawbacks due to a Gaussian initialization. In a Bayesian framework, when the likelihood is Gaussian, we identify the posterior distribution of the output in the sequential wide-width limit and, in the shallow case, we compute explicitly the posterior distribution of these models. The talk is based on a joint work with Nicola Apollonio and Giovanni Franzina. -- Professor of Probability and Statistics Coordinator for Internationalization Dipartimento di Matematica Università di Pisa https://web.dm.unipi.it/trevisan/

Seminario Giles Hooker - Politecnico di Milano
by Laura Maria Sangalli 03 Dec '25

03 Dec '25

Si avvisa che in data 11-12-2025, alle ore 14:30 presso il Politecnico di Milano, Dipartimento di Matematica, Aula Saleri, nell’ambito delle attività del MOX, si svolgerà il seguente seminario: Giles Hooker Department of Statistics and Data Science University of Pennsylvania Titolo: Targeted Machine Learning for the Integration of Mathematical, Numerical, and Statistical models: Integral Projection Models in Environmental Sciences Abstract: Within demographic ecology, integral projection models (IPMs) play an important role in translating models for individual life history into demographic projections about species viability, coexistence, and ecological management practice. Developing an IPM starts with data on individuals from which models are built for their growth, survival and reproduction from one time-period to the next. However, while developing these models often follow classical statistical approaches, there are limited tools to evaluate the uncertainty of the quantities often calculated from IPMS, or to guide model selection given that those quantities are of interest. In this talk we adapt the tools of targeted maximum likelihood estimation (tMLE) to IPMs. Originally developed for causal inference, tMLE methods treat the outcome of interest as a functional of the data distribution and then use the resulting influence function to both correct the bias in these estimates and provide uncertainty quantification. A benefit of this framework is that no structural assumptions need to be made on the model components so long as they exhibit sufficient convergence, allowing for the inclusion of nonparametric and machine learning tools within our toolbox. We will walk through the basic framework of tMLE and its applications to integral projection models particularly in the context of survey data from the Idaho Experimental Sheep Station, as well as pointing to the wide range of open problems and potential of new development. This initiative is part of the “Ph.D. Lectures” activity of the project "Departments of Excellence 2023-2027" of the Department of Mathematics of Politecnico di Milano. This activity consists of seminars open to Ph.D. students, followed by meetings with the speaker to discuss and go into detail on the topics presented during the talk. Il link per seguire il seminario online sarà reso disponibile pochi minuti prima dell’avvio del seminario al seguente indirizzo https://mox.polimi.it/mox-colloquia-seminars-list/mox-seminars/?id_evento=2… Tutti gli interessati sono invitati a partecipare.

Associate Professor in Financial Mathematics (Permanent)
by Eberhard.Mayerhofer 01 Dec '25

01 Dec '25

Dear Colleagues, The University of Limerick recruits a permanent Associate Professor in Financial Mathematics (Deadline in 10 days). You will have a doctoral degree in mathematics or an equivalent discipline and a track record of excellent publications in journals relevant to financial mathematics. (info from myself, not HR) I'm looking for someone to revitalise the Financial Mathematics program here and take on a small teaching load of 3 modules per year, most likely in the field of Financial Mathematics and Probability with small classes (below 60, often 30). Historically, our University has had no more than one Financial Mathematician at a time, and sometimes none at all (another variant of the "0-1 law"). However, the Bachelor's program is well-established since decades, and we are now recruiting to build a strong research team in this field.

Alberto Chiarini e Sonia Mazzucchi %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Ilya Chevyrev (Sissa - Trieste) e Hao Shen (University of Wisconsin-Madison) TITOLO: Stochastic quantisation of gauge theories RIASSUNTO: We will give an introduction to gauge theories, especially Yang-Mills theory, from a probabilistic perspective. Gauge theories arise in physics, where they are used to describe elementary particles, and correspondingly provide many rich problems in mathematics, including in probability and analysis. We will survey recent results on the interaction between quantum Yang-Mills theory and stochastic analysis, especially the field of singular stochastic PDEs. We will describe how the stochastic quantisation equations associated to the 2D and 3D Euclidean Yang-Mills theories can be solved in a geometrically faithful way and what these equations can teach us about the quantum field theory.

SPASS seminar: Giacomo Ascione
by Francesco Grotto 28 Nov '25

28 Nov '25

Dear Colleagues, We would like to invite you to the following SPASS seminars, *Fully nonlocal operators emerging from semi-Markov processes* by Giacomo Ascione (Scuola Superiore Meridionale), TUE 2.12.2025 at 14:00 CET in Sala Riunioni, Dipartimento di Matematica, UNIPI. A link for online participants will be shared on the website https://sites.google.com/unipi.it/spass Best, Francesco Grotto on behalf of the organizers ---------------------------------------------------------------- /Abstract: In the context of anomalous diffusions, time/space-nonlocal operators play a quite prominent role. For instance, the usual fractional Laplacian can be easily recognized as the generator of an isotropic stable Lèvy motion, that, still preserving the Markov property, represent a first (actually pure jump) example of anomalous diffusion, in the sense that the mean square displacement of the described particles (or, in terms of the process, its variance) is not linear in time (actually it is infinite). On the other hand, if we consider the heat equation with a fractional derivative operator in time, a stochastic representation of the solution of such an equation can be given in terms of a Brownian motion time-changed by means of the first passage time process of an independent stable subordinator. This process, however, clearly loses the Markov property, due to the addition of a further dependence on the current sojourn time. In both case, we are describing (at least in terms of the one-dimensional distributions) the behaviour of a time-changed Brownian motion, where the time-change is indeed independent of the process itself. The same can be done if we apply a time-change via an inverse subordinator to an independent isotropic stable Lèvy motion, (obtaining) uncoupled non-local operators in both time and space. However, if we remove the independence assumption, we cannot expect to get uncoupled behaviours in time and space. This is the case, for instance, of a Brownian motion time-changed first with an independent stable subordinator and then with its own inverse. As the second time-change is clearly dependent of the first one, we expect the two operators (in time and space) to be coupled in some way: precisely, in such a case, the Kolmogorov-type equation one gets is governed by a fractional power of the whole heat operator. In this talk, I will present some well-posedness results for fully nonlocal operators obtained by means of Bochner subordination of heat-like operators in terms of a family of semi-Markov processes obtained by means of non-independent time-changes. The general theory will be set in the framework of Feller semigroups on the space of continuous functions vanishing at infinity. Nevertheless, if there is time, a quite specific case (i.e., a Black-Sholes model for intraday options) that requires refined arguments will be discussed and the role of the regularity of the initial data will be addressed. Finally, we will stress the following expected result: despite the appearance of constancy intervals and the lack of Markov property, if we start from a Brownian motion the newly obtained process exhibits a normal diffusive behaviour, instead of an anomalous one./

Online seminar - Department of Economics - Ca' Foscari University of Venice
by Antonella Basso 27 Nov '25

27 Nov '25

Dear all, the Department of Economics of Ca' Foscari University of Venice organizes the following online seminar on*Friday, November 28 at 12:15 (ZOOM only)* by *Guglielmo Alessandro Visentin* (University of Reading) *The Financial Cost of Biodiversity Loss for SMEs *(joint with Lisa Schopohl and Simone Varotto) /Abstract: In this study, we investigate the impact of biodiversity loss on the performance of small and medium-sized enterprises (SMEs) in the United Kingdom and Ireland. Leveraging firms’ financial information and postcodes from Moody’s Bureau van Dijk and the Biodiversity Intactness Index – a geospatial dataset developed by the Natural History Museum – we geo-locate SMEs, quantify biodiversity loss in the area where firms operate, and assess their exposure to biodiversity-related risks over time. We then employ a fixed effects regression model to estimate the effect of biodiversity loss on firm performance. Our findings indicate that a one-standard-deviation decline in biodiversity leads to a statistically significant reduction in firm operating income by 0.59 percentage points. This impact is economically meaningful when benchmarked against the sample’s average operating income. Moreover, SMEs located in more ecologically degraded areas are found to be more exposed to biodiversity-related risks. We also provide evidence of the materiality of dependency risk, while transition risk appears to be non-material within the UK context. The results remain robust across various econometric specifications and when controlling for climate risk factors./ / / The Zoom link is: *https://unive.zoom.us/j/81355902934?pwd=4UWO6ugBkddwqj1v3RCbMNzPhOpIIh.1 ID riunione: 813 5590 2934 Passcode: dN548g */ / More information available here <https://www.unive.it/data/agenda/3/108966>/. / Best regards, Antonella Basso -- Antonella Basso Dipartimento di Economia Università Ca' Foscari Venezia Fondamenta S.

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.google.com/url?q=https://www.carloalberto.org/events/category/s…> Venerdì 05/12/2025, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ 12.00-13.00 Speaker: Andrea CREMASCHI (IE UNIVERSITY MADRID) Title: Dependent Dirichlet-multinomial processes with random number of components Abstract: Bayesian nonparametric methods under partial exchangeability have largely focused on infinite support priors, yet almost-surely finite dimensional dependent mixtures remain underexplored despite their strong theoretical guarantees and performance in the exchangeable case. A novel class of finite dependent Dirichlet-multinomial processes and their counterparts are introduced, incorporating a prior on the number of components. The class is built on generalized Wishart unnormalized weights. It is proven that the normalized diagonals of correlated Wishart matrices admit a hierarchical negative binomial Dirichlet representation whose marginal laws are Dirichlet. The key distributional properties of the induced random probability measures are derived, showing they can achieve any prescribed dependence level and support efficient posterior computation without the need for costly variable augmentation schemes. The practical advantages of the proposed processes are further demonstrated through extensive simulation studies and the analysis of two real datasets: A benchmark dataset and a case study on sex-specific gene expression differences in the human brain, highlighting its flexibility and computational efficiency in capturing complex dependence structures. ------------------------------------------------ Sarà possibile seguire il seminario anche in streaming: chiunque volesse collegarsi è pregato di inviare una email entro *mercoledì 03/12/2025* a matteo.giordano(a)unito.it <mailto:matteo.giordano@unito.it> Il webinar è organizzato dalla "de Castro" Statistics Initiative (www.carloalberto.org/stats <http://www.carloalberto.org/stats>) in collaborazione con il Collegio Carlo Alberto.

REMINDER: OWABI - Clara Grazian - November 27 - 11am UK time
by Massimiliano Tamborrino 26 Nov '25

26 Nov '25

Dear all, this is a kind reminder of the next OWABI seminar www.warwick.ac.uk/owabi<http://www.warwick.ac.uk/owabi> by Clara Grazian<https://www.sydney.edu.au/science/about/our-people/academic-staff/clara-gra…> (University of Sidney), who will talk about "Approximate Bayesian Computation with Statistical Distances for Model Selection" tomorrow, Thursday the 27th November at 11am UK time, with an abstract reported below. Abstract: Model selection is a key task in statistics, playing a critical role across various scientific disciplines. While no model can fully capture the complexities of a real-world data-generating process, identifying the model that best approximates it can provide valuable insights. Bayesian statistics offers a flexible framework for model selection by updating prior beliefs as new data becomes available, allowing for ongoing refinement of candidate models. This is typically achieved by calculating posterior probabilities, which quantify the support for each model given the observed data. However, in cases where likelihood functions are intractable, exact computation of these posterior probabilities becomes infeasible. Approximate Bayesian computation (ABC) has emerged as a likelihood-free method and it is traditionally used with summary statistics to reduce data dimensionality, however this often results in information loss difficult to quantify, particularly in model selection contexts. Recent advancements propose the use of full data approaches based on statistical distances, offering a promising alternative that bypasses the need for handcrafted summary statistics and can yield posterior approximations that more closely reflect the true posterior under suitable conditions. Despite these developments, full data ABC approaches have not yet been widely applied to model selection problems. This paper seeks to address this gap by investigating the performance of ABC with statistical distances in model selection. Through simulation studies and an application to toad movement models, this work explores whether full data approaches can overcome the limitations of summary statistic-based ABC for model choice. Keywords: model choice, distance metrics, full data approaches Reference: C.

Seminar Torrisi at Tor Vergata, December 1
by Michele Salvi 25 Nov '25

25 Nov '25

Dear all, On Monday, December 1st, at 14h00 in Aula Dal Passo of Tor Vergata Math Department, RoMaDS (https://www.mat.uniroma2.it/~rds/events.php) will host Giovanni Luca Torrisi (CNR) with the seminar "Posterior Bayesian Neural Networks with Dependent and Heavy-Tailed Weights” Abstract: We consider fully connected and feedforward deep neural networks with dependent and possibly heavy-tailed weights. These networks have been introduced to alleviate the drawbacks due to a Gaussian initialization. In a Bayesian framework, when the likelihood is Gaussian, we identify the posterior distribution of the output in the sequential wide-width limit and, in the shallow case, we compute explicitly the posterior distribution of these models. The talk is based on a joint work with Nicola Apollonio and Giovanni Franzina. We encourage in-person partecipation.

21 Nov '25

Dear all, on* Thursday 27th November* the following seminars will be held at the *Department of Statistical Sciences, Sapienza University*: *Time: 14:30* *Speaker: Lorenzo Cristofaro (University of Luxembourg)* *Title: *A novel p-Poincaré inequality and a multiplication formula *Abstract:* We show a novel family of p-Poincaré inequalities for almost surely finite random variables (p ∈ [1, 2]). Regarding the case of multiple Wiener-Ito integrals, our results yield general multiplication formulae on the Poisson space under minimal conditions, naturally expressed in terms of diagrams and/or contraction operators. *Time: 15:15* *Speaker: Wolfgang Bock (Linnaeus University, Vaxjo, Sweden)* *Title: *The characterization of Malliavin-Watababe-Sobolev spaces via the Bargmann-Segal Space *Abstract: *The characterization theorem and its corollaries set the foundation of the success of white noise analysis in the recent 30 years. On different occasions the fathers of the characterization J. Potthoff and L. Streit were asked by P. Malliavin and P.-A. Meyer if such a characterization is also possible for the Mallliavin-Watanabe Sobolev spaces. In this talk we present how we closed this gap and give a characterization of the Mallliavin-Watanabe Sobolev spaces with the help of the Bargmann-Segal transform. The characterization can also be generalized to the non-Gaussian setting. Examples will showcase the regularity of different objects.

SPASS seminars: E. Tassi and J. Coe
by Francesco Grotto 20 Nov '25

20 Nov '25

Dear Colleagues, We would like to invite you to the following SPASS seminars, *Hamiltonian fluid models for plasmas in the presence of a strong guide field* by Emanuele Tassi (Observatoire de la Côte d'Azur), and *Transition densities for the 2d stochastic Navier-Stokes equations* by James Coe (University of Edinburgh), to be held consecutively on TUE 25.11.2025 at 14:00 and 15:00 CET in Sala Riunioni, Dipartimento di Matematica, UNIPI. A link for online participants will be shared on the website https://sites.google.com/unipi.it/spass Best, Francesco Grotto on behalf of the organizers ---------------------------------------------------------------- /Abstract (Tassi): Fluid models provide an effective tool for describing the dynamics of ionized gases such as plasmas. In particular, in some laboratory and astrophysical contexts (for instance, tokamak devices for thermonuclear fusion, or the solar wind) the dynamics of a plasma can be effectively described by means of fluid models assuming the presence of a dominant, constant in time, component of the magnetic field (strong guide field assumption). Several models of this kind have been derived and used for studying phenomena such as turbulence and magnetic reconnection. In the two-dimensional, non-dissipative limit, many of these models were shown to possess a reformulation in terms of advection equations for Lagrangian invariants. A paradigmatic example of this family of models consists of the two-field model derived by Schep, Pegoraro and Kuvshinov (Phys. Plasmas 1, 2843 (1994)). The formulation in terms of Lagrangian invariants is concomitant with the noncanonical Hamiltonian structure of these models.In this talk, I will show how the possibility of this reformulation and the existence of the corresponding noncanonical Hamiltonian structure can be traced back to the common origin of these models from a parent kinetic model of the so-called gyrokinetic, or drift-kinetic kind.With this approach, new Hamiltonian fluid models can also be derived, describing the evolution of an arbitrary number of Lagrangian invariants in two dimensions. Some general properties of models that can be derived by means of this approach will also be discussed. / /Abstract (Coe): We consider a family of 2d incompressible Navier-Stokes equations with Gaussian forcing that is white-in-time and coloured-in-space. We show that the laws of solutions at any given time are equivalent to those of the corresponding Ornstein-Uhlenbeck process, and in particular the invariant measures are equivalent.We establish a nonlinear version of the "time-shifted Girsanov method" of [Mattingly-Suidan, Mattingly-Romito-Su], enabling a direct comparison between the laws of nonlinear dissipative SPDEs. Then, exploiting the skew-symmetric structure of the Navier-Stokes nonlinearity, we construct a modified system that leaves the Gaussian measure invariant while remaining comparable to the Navier-Stokes dynamics. This talk is based on joint work with Martin Hairer and Leonardo Tolomeo. /

Seminar Andreis at Tor Vergata, November 24
by Michele Salvi 19 Nov '25

19 Nov '25

Dear all, On Monday, November 24th, at 14h00 in Aula Dal Passo of Tor Vergata Math Department, RoMaDS (https://www.mat.uniroma2.it/~rds/events.php) will host Luisa Andreis (Università degli studi di Torino) with the seminar "Large deviations for the covariance process in fully connected Gaussian neural networks” Abstract: In this talk, we study fully connected Gaussian deep neural networks, focusing on their covariance process. In particular, we establish a large deviation principle (LDP) for this process in a functional framework, viewing it as a trajectory in the space of continuous functions. As key applications of our main results, we derive posterior LDPs under Gaussian likelihoods in both the infinite-width and mean-field regimes. We will outline the main ideas of the proof, emphasizing that it relies on an LDP for the covariance process regarded as a Markov process taking values in the space of non-negative, symmetric, trace-class operators equipped with the trace norm. This talk is based on joint work with F. Bassetti and C. Hirsch. We encourage in-person partecipation.

17 Nov '25

Buongiorno a tutti, Vorremmo segnalarvi che venerdì prossimo (3 Ottobre) in aula 2AB40 (Torre Archimede, Università di Padova) ci sarà un seminario per il ciclo di seminari in Probabilità e Finanza di: Simone Baldassarri (Gran Sasso Science Institute (GSSI)) <https://sites.google.com/view/simonebaldassarri> https://sites.google.com/view/simonebaldassarri Title: How opinions evolve on dense dynamic random graphs Date: October 3, 2025, at 14:30, 2AB40 Abstract: Describing the evolution of dynamic networks together with dynamic processes running on them constitutes a major challenge in network science. Despite considerable efforts in past years, and notable progress on an intuitive and approximative level, our mathematical understanding of such systems is still in its infancy. The focus of this talk will be two-opinion voter models on dense dynamic random graphs. The goal is to understand and describe the occurrence of consensus versus polarisation over long periods of time. The former means that all vertices have the same opinion, the latter means that the vertices split into two communities with different opinions and few disagreeing edges. We consider three models for the joint dynamics of opinions and graphs: one with one-way feedback and two with two-way feedback. Key results cover functional laws of large numbers for the densities of the two opinions, functional laws of large numbers for the dynamic random graphs in the space of graphons, and a characterisation of the limiting densities in terms of Beta-distributions. This talk is based on a joint work with P. Braunsteins, F. den Hollander and Michel Mandjes. Vi aspettiamo numerosi!

REMINDER: [STAR Seminars] Tuesday Nov 18 - Ihsan Arharas
by Leonardo Tarquini 17 Nov '25

17 Nov '25

Dear all, This is a gentle reminder about this week's STAR seminar scheduled for tomorrow, November 18th, from 13:00 to 14:00 (Oslo time). As always, the talk will take place in a hybrid format: participants in Oslo can attend the talk in Møterom 1000 in Niels Henrik Abels hus, whereas the international audience will be able to follow the talk via Zoom<https://uio.zoom.us/j/65363110080>. The speaker is Ihsan Arharas (Linnaeus University) with the talk: Title: American options under asymmetric information in the predictable setting Abstract: We study the valuation of American contingent claims with irregular payoff processes in a financial market where the buyer possesses additional information. The seller operates with respect to the public filtration, while the buyer acts under an initially enlarged filtration. In this setting, we investigate the value of the American contingent claim when the buyer exercises the option according to predictable stopping strategies, i.e. exercise rules that can be announced in advance. This formulation is particularly relevant in the absence of regularity, since enlargement may transform jump times that are totally inaccessible under the public filtration into predictable times under the enlarged one. Within this framework, the value of the American contingent claim is characterized through the solution of a reflected backward stochastic differential equation (RBSDE) in the predictable setting, and the difference between the two information structures provides a representation of the cost of the additional information. We are looking forward to seeing you! Best regards, Giulia, Leonardo and Pere

Seminario Maurice Duits Sapienza
by Gustavo Posta 17 Nov '25

17 Nov '25

Dear all, On Monday November 24, Maurice Duits (http://www.math.kth.se/~duits) will give a seminar at the Department of Mathematics "Guido Castelnuovo" (Sapienza Università di Roma). Please find the details below. GP ************************************************ Monday November 24 2025 16:15, Sala Consiglio del Dipartimento di Matematica "Guido Castelnuovo" Sapienza Università di Roma Speaker: Maurice Duits Title: The Gamma disordered Aztec diamond Abstract: The Aztec diamond, under the uniform measure on domino tilings, is one of the classic examples of an exactly solvable model in probability and statistical mechanics. Its rich geometric features—such as limit shapes and arctic boundaries—have long made it a cornerstone of integrable probability. More recently, variants of this model with doubly periodic weights have revealed that much of the underlying structure persists far beyond the uniform case and can be used to uncover new behaviors—such as regions with smooth disorder—that were previously out of reach. At the heart of these models lies a birational map that encodes their integrable character. In this talk, I will present a new disordered version of the Aztec diamond obtained by placing Gamma-distributed weights on its edges. Remarkably, these random weights preserve just enough structure to keep the model integrable, This allows us to provide rigorous confirmation of predictions from the physics literature—such as the absence of a phase transition in the free energy—and explain the emergence of n^2/3 fluctuations near the turning points. Remarkably, these turning points are related to certain integrable polymer models. The presentation is aimed at a broad mathematical audience and is based on on joint work with Roger van Peski. ************************************************ ---------------------------------------------------------------- Gustavo Posta Dipartimento di Matematica Università di Roma "la Sapienza" P.le A.

SPASS Seminar: Matteo Palmieri
by Francesco Grotto 16 Nov '25

16 Nov '25

Dear Colleagues, We would like to invite you to the following SPASS seminar, *On minimizing curves in a Brownian potential* by Matteo Palmieri (Max Planck Inst. Lepzig), WED 19.11.2025 at 14:00 CET in Saletta Riunioni, Dipartimento di Matematica, UNIPI. Best, Francesco Grotto on behalf of the organizers https://sites.google.com/unipi.it/spass ---------------------------------------------------------------- /Abstract: We study a (1+1)-dimensional semi-discrete random variational problem that can be interpreted as the geometrically linearized version of the critical 2-dimensional random field Ising model (at zero temperature). We show that at every dyadic scale from the system size down to the lattice spacing the minimizer contains at most order-one Dirichlet energy per unit length, leading to a logarithmic scaling of the minimal energy. Using super-additivity in the scales, this allows us to establish a quenched homogenization result in the sense that he leading order of the minimal energy becomes deterministic as the ratio system size/lattice spacing diverges. This is joint work with Felix Otto and Christian Wagner./

OWABI - Clara Grazian - November 27 - 11am UK time
by Massimiliano Tamborrino 13 Nov '25

13 Nov '25

Dear all, the next OWABI seminar www.warwick.ac.uk/owabi<http://www.warwick.ac.uk/owabi> is quickly approaching! Our next speaker is Clara Grazian<https://www.sydney.edu.au/science/about/our-people/academic-staff/clara-gra…> (University of Sidney), who will talk about "Approximate Bayesian Computation with Statistical Distances for Model Selection" on Thursday the 27th November at 11am UK time, with an abstract reported below. Abstract: Model selection is a key task in statistics, playing a critical role across various scientific disciplines. While no model can fully capture the complexities of a real-world data-generating process, identifying the model that best approximates it can provide valuable insights. Bayesian statistics offers a flexible framework for model selection by updating prior beliefs as new data becomes available, allowing for ongoing refinement of candidate models. This is typically achieved by calculating posterior probabilities, which quantify the support for each model given the observed data. However, in cases where likelihood functions are intractable, exact computation of these posterior probabilities becomes infeasible. Approximate Bayesian computation (ABC) has emerged as a likelihood-free method and it is traditionally used with summary statistics to reduce data dimensionality, however this often results in information loss difficult to quantify, particularly in model selection contexts. Recent advancements propose the use of full data approaches based on statistical distances, offering a promising alternative that bypasses the need for handcrafted summary statistics and can yield posterior approximations that more closely reflect the true posterior under suitable conditions. Despite these developments, full data ABC approaches have not yet been widely applied to model selection problems. This paper seeks to address this gap by investigating the performance of ABC with statistical distances in model selection. Through simulation studies and an application to toad movement models, this work explores whether full data approaches can overcome the limitations of summary statistic-based ABC for model choice.

Seminario Lucas D'Alimonte, Lunedì 17 Novembre, Sapienza Università di Roma
by Silvestri, Vittoria 13 Nov '25

13 Nov '25

Segnalo il seguente seminario, che si terrà Lunedì prossimo in Sapienza. *Lunedì 17 Novembre, ore 16:15,* Sala di Consiglio, Dipartimento di Matematica, Sapienza Università di Roma *Speaker:* Lucas D'Alimonte (LPSM Sorbonne Université) *Title:* Ornstein—Zernike theory for the near-critical planar random cluster model *Abstract:* In this talk, we will discuss the classical Ornstein-Zernike theory for the random-cluster model (also known as FK percolation). In its modern form, it is a very robust theory, which most celebrated output is the computation of the asymptotically polynomial corrections to the pure exponential decay of the two-points correlation function of the random-cluster model in the subcritical regime. We will present an ongoing project that extends this theory to the near-critical regime of the two-dimensional random-cluster model, thus providing a precise understanding of the Ornstein-Zernike asymptotics when papproaches the critical parameter p_c. The output of this work is a formula encompassing both the critical behaviour of the system when looked at a scale negligible with respect to its correlation length, and its subcritical behaviour when looked at a scale way larger than its correlation length. Based on a joint work with Ioan Manolescu. ******************************** Vittoria Silvestri Associate Professor Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome ********************************

REMINDER: [STAR Seminars] Tuesday Nov 11 - Paul Ehling
by Leonardo Tarquini 10 Nov '25

10 Nov '25

Dear all, This is a gentle reminder about this week's STAR seminar scheduled for tomorrow, November 11th, from 13:00 to 14:00 (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/62796699609>. The speaker is Paul Ehling (BI Norwegian Business School) with the talk: Title: Asset pricing implications of default Abstract: Studying the asset pricing implications of default, we show that default along the equilibrium path reduces the amount of risk-sharing for two reasons. First, the potential of future default events for relatively poor agents increases their cost of borrowing today. Second, the option value of default in the future induces increased borrowing today, even for relatively rich agents. We establish that agents borrow from each other simultaneously in equilibrium and that they borrow more when idiosyncratic risk is high. Further, we show that this increases the probability of default along the equilibrium path which drives up the premium on risky assets. To solve our dynamic model example with multiple agents numerically, we rely on a machine learning framework to overcome the large state space and the non-linearities due to default. We are looking forward to seeing you! Best regards, Giulia, Leonardo and Pere

Dear all, Join us for our upcoming talk in the STAR seminar<https://www.mn.uio.no/math/english/research/projects/storm/events/seminars/…> series Tuesday, November 18th, from 13:00 to 14:00 (Oslo time). As always, the talk will take place in a hybrid format: participants in Oslo can attend the talk in Møterom 1000 in Niels Henrik Abels hus, whereas the international audience will be able to follow the talk via Zoom<https://uio.zoom.us/j/62796699609>. The speaker is Ihsan Arharas (Linnaeus University) with the talk: Title: American options under asymmetric information in the predictable setting Abstract: We study the valuation of American contingent claims with irregular payoff processes in a financial market where the buyer possesses additional information. The seller operates with respect to the public filtration, while the buyer acts under an initially enlarged filtration. In this setting, we investigate the value of the American contingent claim when the buyer exercises the option according to predictable stopping strategies, i.e. exercise rules that can be announced in advance. This formulation is particularly relevant in the absence of regularity, since enlargement may transform jump times that are totally inaccessible under the public filtration into predictable times under the enlarged one. Within this framework, the value of the American contingent claim is characterized through the solution of a reflected backward stochastic differential equation (RBSDE) in the predictable setting, and the difference between the two information structures provides a representation of the cost of the additional information. We are looking forward to seeing you! Best regards, Giulia, Leonardo and Pere

Avviso di seminario - Prof. Kei Kobayashi
by luigia.caputo 04 Nov '25

04 Nov '25

Il giorno 10 novembre 2025, alle ore 15:00, in SP1L, del Dipartimento di Matematica e Applicazioni R. Caccioppoli, il Prof. Kei Kobayashi, Department of Mathematics, Fordham University, terrà il seguente seminario: "Eﬀect of random time changes on Loewner hulls" Abstract: Standard Brownian motion composed with a random time change given by an inverse subordinator has been used to model subdiﬀusions, where particles spread more slowly than the classical Brownian particles. The time-changed Brownian motion is neither Markovian nor Gaussian, and standard procedures known for normal diﬀusions do not generally work. This talk gives an overview of the framework of numerical approximation schemes for the time-changed Brownian motion and its associated stochastic diﬀerential equations, along with the rates of convergence. This is based on joint work with Sixian Jin and Ernest Jum. Sarà possibile seguire il seminario anche on line all'indirizzo: Seminario Prof. Kei Kobayashi | Partecipazione alla riunione | Microsoft Teams [1] Cari saluti, Luigia Caputo -- Luigia Caputo, PhD Ricercatore Universitario di Probabilità e Statistica Matematica, Dipartimento di Matematica e Applicazioni, Università di Napoli FEDERICO II Via Cintia, 80126, NAPOLI https://www.docenti.unina.it/luigia.caputo Links: ------ [1] https://teams.microsoft.com/meet/3820570043887?p=SREudpw04NV0e4hOLU

[STAR Seminars] Tuesday Nov 11 - Paul Ehling
by Leonardo Tarquini 03 Nov '25

03 Nov '25

Dear all, Join us for our upcoming talk in the STAR seminar<https://www.mn.uio.no/math/english/research/projects/storm/events/seminars/…> series Tuesday, November 11th, from 13:00 to 14:00 (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/62796699609>. The speaker is Paul Ehling (BI Norwegian Business School) with the talk: Title: Asset pricing implications of default Abstract: Studying the asset pricing implications of default, we show that default along the equilibrium path reduces the amount of risk-sharing for two reasons. First, the potential of future default events for relatively poor agents increases their cost of borrowing today. Second, the option value of default in the future induces increased borrowing today, even for relatively rich agents. We establish that agents borrow from each other simultaneously in equilibrium and that they borrow more when idiosyncratic risk is high. Further, we show that this increases the probability of default along the equilibrium path which drives up the premium on risky assets. To solve our dynamic model example with multiple agents numerically, we rely on a machine learning framework to overcome the large state space and the non-linearities due to default. We are looking forward to seeing you! Best regards, Giulia, Leonardo and Pere

Alberto Chiarini e Sonia Mazzucchi %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Lucas Benigni (Università di Montreal) e Giorgio Cipolloni (Università di Roma 2 Tor Vergata) TITOLO: The mystery of universality in Random Matrix Theory. RIASSUNTO: Over the past fifteen years, our understanding of universality in random matrix theory has undergone a remarkable transformation. For many models of large random matrices, it is now known that both eigenvalue statistics and eigenvector structures exhibit universal behavior that depends only on the symmetry class and not on the fine details of the matrix entries. This universality lies at the heart of deep conjectures in mathematical physics—connecting topics as diverse as quantum chaos, number theory, and high-dimensional statistics—and has become one of the major success stories of modern probability theory. In this two-part colloquium, we will survey these advances with a focus on Wigner matrices, Hermitian or symmetric random matrices with i.i.d. entries up to the symmetry constraint. The first part will discuss universality of eigenvalues, from local spectral laws to modern proofs of universality of local statistics. The second part will turn to eigenvectors, highlighting recent progress on delocalization, quantum ergodicity, and eigenvector statistics.

Under this scenario we do not have access to pairs of observations from the distribution of $(X, Y)$, but instead we have separate data sets $\{Y_i\}_{i=1}^n$ and $\{X_j\}_{j=1}^m$, possibly collected from different sources. We study this problem assuming that the regression function is linear and the noise distribution is known or can be estimated. We introduce an estimator of the regression vector based on deconvolution (the DLSE) and demonstrate its consistency and asymptotic normality under an identifiability assumption. Under non-identifiability of the regression vector but identifiability of the distribution of the predictor, we construct an estimator of the latter based on the DLSE and show that it converges to the true distribution of the predictor at the parametric rate in the Wasserstein distance of order 1. We illustrate the theory with several simulation results. ------------------------------------------------ Sarà possibile seguire il seminario anche in streaming: chiunque volesse collegarsi è pregato di inviare una email entro *mercoledì 05/11/2025* a matteo.giordano(a)unito.it <mailto:matteo.giordano@unito.it> Il webinar è organizzato dalla "de Castro" Statistics Initiative (www.carloalberto.org/stats <http://www.carloalberto.org/stats>) in collaborazione con il Collegio Carlo Alberto.

Maria Kalli and Jim Griffin Seminars at Ca' Foscari University of Venice - 3 November 2025
by Roberto CASARIN 31 Oct '25

31 Oct '25

Dear Colleagues, I'm pleased to invite you to the Department Seminars, which will be held on Monday, November 3 at 11:00 in Meeting Room 1 with the following schedule: - 11:00-12:00: *Maria Kalli *(*King's College London*), Network Modeling of Asynchronous Change-Points in Multivariate Time Series - 12.15- 13.15: *Jim Griffin* (*University College London*), Some approaches to modelling high-dimensional multivariate time series All the interested researchers are warmly invited to attend in person or online! Best regards Roberto Casarin (and on behalf of the Organizing Committee) More information and Zoom link are available here: https://www.unive.it/data/agenda/1/104528 https://unive.zoom.us/j/81247640154?pwd=rPM81OcUZRb5VIW4NSHwOPLurD01le.1 *Title*: Network Modeling of Asynchronous Change-Points in Multivariate Time Series *Abstract *: We introduce a novel Bayesian method for asynchronous change-point detection in multivariate time series. This method allows for change-points to occur earlier in some (leading) series followed, after a short delay, by change-points in some other (lagging) series. Such dynamic dependence structure is common in fields such as seismology and neurology where a latent event such as an earthquake or seizure causes certain sensors to register change-points before others. We model these lead-lag dependencies via a latent directed graph and provide a hierarchical prior for learning the graph’s structure and parameters. Posterior inference is made tractable by modifying particle MCMC methods designed for univariate change-point problems. We apply our method to both simulated and real datasets from the fields of seismology and neurology. In the simulated data, we find that our method outperforms competing methods in settings where the change-point locations are dependent across series. In the real data applications we show that our model can also uncover an interpretable network structure. *Title*: Some approaches to modelling high-dimensional multivariate time series *Abstract*: There has been an increasing interest in modelling high-dimensional multivariate economic time series. Many models build on the work-horse Vector AutoRegression (VAR) and its time-varying extension to TVP-VAR. These models can provide better forecasts and structural analysis than low-dimensional models (particularly during crisis periods) but the large number of parameters can be challenging both inferentially and computationally. In this talk, I will review two recent approaches. The first is the Tensor VAR (TVAR) model which uses a tensor structure to achieve dimension reduction in the coefficient matrices of the VAR. I will discuss Bayesian inference in these models and an extension to a time-varying parameter model. The second approach considers the time-varying Factor Augmented VAR (FA-VAR) and uses an autoencoder to extract low-dimensional non-linear factors from high-dimensional data. I will discuss how a shrinkage prior using groupings of the variables can lead to identifiable factors and better predictive performance. -- Roberto Casarin, PhD Professor of Econometrics Ca' Foscari University of Venice San Giobbe 873/b - 30121 Venezia, Italy http://sites.google.com/view/robertocasarin/ https://www.unive.it/vera <https://www.unive.it/isba2024> https://www.unive.it/isba2024

Seminario Kais Ammari - Politecnico di Milano - 3 Novembre 2025
by Luca Scarpa 29 Oct '25

29 Oct '25

Si segnala il seguente seminario a tutti gli interessati. Lunedì 3 Novembre 2025, ore 14:30. Aula Seminari VI Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Kais Ammari, University of Monastir. Title: Degenerate Damping in Interacting Elastic Systems. Abstract: We study the regularity and stability of coupled elastic systems subject to distinct damping mechanisms: one acting through the average velocity and another via a fractional power of the elastic operator. The damping matrix is degenerate, meaning that dissipation does not affect all components equally. Using a frequency-domain approach based on resolvent estimates, we describe how this degeneracy influences the semigroup regularity and the decay of solutions. The obtained results are shown to be optimal and relevant for applications in structural mechanics and vibration control.

Nov 6 - Stats seminars Kopp @ Sapienza MEMOTEF
by Francesca Panero 29 Oct '25

29 Oct '25

Carissimi tutti, On Thursday 6th of November at the MEMOTEF Department, Sapienza University, we will have the pleasure to listen to the seminar of Emma Kopp<https://emmakopp1.github.io>, PhD student from CERMADE Paris-Dauphine University, with title Recent work on phylogenetics applied to historical linguistic and cultural evolution. The seminar will take place 9-10am in Aula Cristina Di Fresco (4th floor of the Economics building, administration corridor, Via del Castro Laurenziano 9 Roma). You can find the abstract below. Best wishes, Francesca Recent work on phylogenetics applied to historical linguistic and cultural evolution Linguistic phylogenies reconstruct the evolutionary relationships between languages based on cognate data (presence/absence of shared linguistic traits). We use theoretical bounds derived from Mossel's work to determine the temporal limit to which phylogenetic methods can reliably reconstruct linguistic tree topology or ancestral states. The study combines simulation of synthetic data on trees to assess reconstruction accuracy as a function of tree age and number of cognates, and ancestral state reconstruction on real lexical data from Sino-Tibetan and Bantu language families. The study methodologically demonstrates that for languages evolving at rates typically observed in the literature, it is impossible to reconstruct the topology of a tree whose root age exceeds 12,000 years. Beyond this threshold, the inferred topology will be no more reliable than a random estimate. Analysis shows that increasing the number of traits improves reconstruction for ancient trees, but gains remain limited. Ancestral state reconstruction results show that certain semantic categories (body parts, numerical concepts and natural elements) can be reconstructed at remarkable temporal depths. This convergence in the retention of essential concepts suggests the existence of universal constraints in lexical evolution. These results establish for the first time a theoretical quantitative bound on phylolinguistic methods, demonstrating that reconstruction of deep topologies of ancient linguistic families based on cognate lexical data constitutes a doomed enterprise. ------------------------------------------- Dr Francesca Panero (she/her) Assistant Professor in Statistics (RTT), Department of Methods and Models for Economics, Territory and Finance Sapienza University, Rome Visiting Fellow, Department of Statistics London School of Economics and Political Science Visiting Lecturer, Faculty of Informatics Università della Svizzera Italiana Website: https://francescapanero.github.io

Seminars of Tiozzo, Klippel, Jara and D'Alimonte at La Sapienza
by Faggionato, Alessandra 29 Oct '25

29 Oct '25

Dear all, In addition to the already announced seminar by Tiozzo today (*Harmonic functions on groups, random walks, and the identification of the Poisson boundary*), we will have three seminars in Probability at the Department of Mathematics of Sapienza University in the coming weeks. The speakers will be Andreas Klippel (TU Darmstadt), Milton Jara (IMPA, Rio de Janeiro), and Lucas D’Alimonte (LPSM – Sorbonne Université). Below you can find the titles and abstracts. Buona giornata Alessandra ************************************************** *Monday, November 3 2025* *16:15, Sala di Consiglio, Dipartimento di Matematica* *Speaker: *Andreas Klippel (TU Darmstadt) *Title*: Two Sides of One Coin: Approaches to the Random Loop Model *Abstract: *In the last decades, graphical representations have emerged as powerful tools to study models from statistical physics. One prominent example is the random loop model, whose two-point function encodes various spin correlations of quantum systems such as the Heisenberg ferromagnet, the antiferromagnet, and the quantum XY model. Since the model lacks monotonicity properties and correlation inequalities such as FKG, alternative techniques have been developed to analyze it. We will discuss two complementary approaches suitable for different regimes. The first concerns the absence of long loops, corresponding to the regime without a phase transition. This situation can be studied by comparing the model to a percolation process and showing that certain structural features effectively reduce the percolation parameter, leading to exponentially small loops. The second approach addresses the occurrence of a phase transition, which is typically established through the method of reflection positivity. The presentation will provide an introduction to the random loop model, outline these two analytical techniques, and present several results illustrating their application. ********************************************************************* *Monday, November 10 2025* *16:15, Sala di Consiglio, Dipartimento di Matematica* *Speaker: *Milton Jara (Impa, Rio de Janeiro) *Title*: Quantitative Hydrodynamics for a generalized contact model *Abstract: *We use the formalism of Quantitative Hydrodynamics to improve the quantitative hydrodynamic limit obtained in Chariker, De Masi, Lebowitz and Presutti (2023) for an interacting particle system inspired by integrate-and-fire neuron models. Our estimates are good enough to show that the typical fluctuations around the aforementioned hydrodynamic limit are Gaussian, and governed by an inhomogeneous stochastic linear equation. Joint work with Julian Amorim (IMPA) and Yangrui Xiang (Louisiana State University) *********************************************************************** *Monday, November 17 2025* *16:15, Sala di Consiglio, Dipartimento di Matematica* *Speaker: *Lucas D’Alimonte (LPSM - Sorbonne Université) *Title:* Ornstein—Zernike theory for the near-critical planar random cluster model *Abstract:* In this talk, we will discuss the classical Ornstein-Zernike theory for the random-cluster model (also known as FK percolation). In its modern form, it is a very robust theory, which most celebrated output is the computation of the asymptotically polynomial corrections to the pure exponential decay of the two-points correlation function of the random-cluster model in the subcritical regime. We will present an ongoing project that extends this theory to the near-critical regime of the two-dimensional random-cluster model, thus providing a precise understanding of the Ornstein-Zernike asymptotics when p approaches the critical parameter p_c. The output of this work is a formula encompassing both the critical behaviour of the system when looked at a scale negligible with respect to its correlation length, and its subcritical behaviour when looked at a scale way larger than its correlation length. Based on a joint work with Ioan Manolescu. -- ************************************************* Prof. Alessandra Faggionato https://www1.mat.uniroma1.it/people/faggionato/ Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome Office 123, first floor *************************************************

This gives a dynamical extension of the celebrated result by Rider and Virag (2006) proving that the fluctuations of the eigenvalues of Gaussian non-Hermitian matrices converge to the Gaussian Free Field. Milton Jara (IMPA, Rio de Janeiro) "NESS for KPZ" We show that the fluctuations of the density of boundary driven, weakly asymmetric systems are described by energy solutions of the KPZ equation with corresponding boundary conditions. Conditioned on the uniqueness of these energy solutions, we show that the non-equilibrium stationary states (NESS) of these systems are described by the invariant measures of KPZ introduced by Barraquand, Bryc, Corwin, Knizel among others. Joint work with Juan Arroyave (IMPA). Maurice Duits (KTH Royal Institute of Technology, Stockholm) "Integrable Structures Behind the Aztec Diamond" The Aztec diamond, under the uniform measure on domino tilings, is one of the classic examples of an exactly solvable model in probability and statistical mechanics. Its rich geometric features—such as limit shapes and arctic boundaries—have long made it a cornerstone of integrable probability. More recently, variants of this model with doubly periodic weights have revealed that much of the underlying structure persists far beyond the uniform case and can be used to uncover new behaviors—such as regions with smooth disorder—that were previously out of reach. At the heart of these models lies a birational map that encodes their integrable character. In this talk, I will describe how this map unifies different regimes of the Aztec diamond—from uniform and periodic settings to models in random environments. I will also discuss how integrable features survive (sometimes unexpectedly) in the presence of disorder, and how they connect to other probabilistic models such as directed polymers. The presentation is aimed at a broad mathematical audience, and no prior background in tilings or integrable systems will be assumed.

Seminario di Kei Kobayashi

Carissimi di seguito trovate l'avviso del seminario: -- AVVISO DI SEMINARIO   Giovedì 30 ottobre, alle ore 12:30, in aula G del Dipartimento di Matematica e Fisica dell'Università della Campania Luigi Vamvitelli, in Viale Lincoln 5, Caserta, Kei Kobayashi Professor of Mathematics, Department of Mathematics, Fordham University, New York, USA, terrà un seminario dal titolo Parameter estimation for one-sided heavy-tailed distributions Abstract: Stable subordinators have been widely used in the context of subdiffusions, where particles get trapped or immobile in a number of time periods, called constant periods. The lengths of the constant periods follow a one-sided stable distribution whose first moment does not exist. In this talk, we construct an estimator for the stability index, applying the method of moments to the number of observed constant periods in a fixed time interval. The resulting estimator is asymptotically unbiased and consistent, and it is well-suited for situations where multiple observations of the same subdiffusion process are available. We present supporting numerical examples and an application to market price data for a low-volume stock. This is joint work with Phillip Kerger. -- Questo è il link da remoto: Seminario di Kei Kobayashi | Partecipazione alla riunione | Microsoft Teams<https://teams.microsoft.com/meet/3305423649328?p=buYuVJgBIf5KihIoRS> Cari saluti Enrica Pirozzi

Buongiorno, vi segnalo il seminario di Giulio Tiozzo organizzato dal gruppo di Algebra e Geometria per questo Mercoledi' (sotto i dettagli) Saluti Alessandra %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% *Mercoledì 29 ottobre 2025* Ore 14:00, Sala di Consiglio, Dipartimento di Matematica, Sapienza Università di Roma Seminario di Algebra e Geometria Giulio Tiozzo (Sapienza Università di Roma) *Harmonic functions on groups, random walks, and the identification of the Poisson boundary* The Poisson boundary is a measure-theoretic object attached to a group equipped with a probability measure, and is closely related to the notion of harmonic function on the group. In many cases, the group is also endowed with a topological boundary arising from its geometric structure, and a recurring research theme is to identify the Poisson boundary with the topological boundary. For instance, for lattices in hyperbolic space, it is natural to ask if the (visual, or Gromov-)boundary of the hyperbolic space is a model for the Poisson boundary. In this talk, we solve the identification problem for the Poisson boundary of a random walk with finite entropy on a hyperbolic group and on a discrete subgroup of a semisimple Lie group. The main technical novelty is that we do not require any moment assumption on the measure. Joint with K. Chawla, B. Forghani, and J.

Reminder: OWABI talk - F-X Briol - October 30 - 11am UK time
by Massimiliano Tamborrino 27 Oct '25

27 Oct '25

Dear all, a kind reminder that the next One World Approximate Bayesian Inference (OWABI) Seminar<https://warwick.ac.uk/fac/sci/statistics/news/upcoming-seminars/abcworldsem…> is scheduled on Thursday the 30th October at 11 am UK time. The 1st OWABI talk of the Season will be given by François-Xavier Briol<https://fxbriol.github.io/> (University College London). who will talk about "Multilevel neural simulation-based inference<https://arxiv.org/abs/2506.06087>" , with an abstract reported below. Abstract: Neural simulation-based inference (SBI) is a popular set of methods for Bayesian inference when models are only available in the form of a simulator. These methods are widely used in the sciences and engineering, where writing down a likelihood can be significantly more challenging than constructing a simulator. However, the performance of neural SBI can suffer when simulators are computationally expensive, thereby limiting the number of simulations that can be performed. In this paper, we propose a novel approach to neural SBI which leverages multilevel Monte Carlo techniques for settings where several simulators of varying cost and fidelity are available. We demonstrate through both theoretical analysis and extensive experiments that our method can significantly enhance the accuracy of SBI methods given a fixed computational budget. Keywords: Multifidelity, neural SBI, multi-level Monte Carlo The talk will be streamed on MS Teams: Join the meeting now<https://teams.microsoft.com/l/meetup-join/19%3adhZ_4e_XLNJzCXPAMzTvT6BZ5KSh…> Meeting ID: 358 173 458 006 0 Passcode: Vp2975vC We are looking forward to seeing you all, best, Massimiliano on the behalf of the OWABI Organisers ------ Dr. Massimiliano Tamborrino Reader (Associate Professor) and WIHEA Fellow Department of Statistics University of Warwick https://warwick.ac.uk/tamborrino

In this talk, we investigate control strategies for a zero-temperature two-dimensional Ising model on a finite square lattice evolving under Metropolis dynamics. Specifically, we consider a situation in which an external controller aims to drive the system from a configuration with a small droplet of +-spins towards the all-plus configuration by flipping spins at specific sites at predetermined moments in time. In order to analyze this control problem, we formulate it as a Markov decision process (MDP), a well-established framework for sequential decision-making problems under uncertainty. To find an optimal policy in this MDP, we construct a simplified model by means of a reduction of the configuration space to the local minima of the Hamiltonian. Leveraging the convenient form of this simplified model, we uncover the structure of the optimal policy by solving the Bellman equations in a recursive manner. Finally, we present simulation results illustrating the performance of this optimal policy in the original control problem at low temperatures. *

Si segnala il seguente seminario a tutti gli interessati. Martedì 28 Ottobre 2025, ore 11:00. Aula Seminari III Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Anna Donadini, Università di Milano-Bicocca. Title: Directed polymer in space-correlated disorder. Abstract: Directed polymers in random environments describe a perturbation of the simple random walk by a random disorder (environment). The partition function of such models has been extensively studied in recent years, also due to its connection with the solution of the Stochastic Heat Equation. While classical results focus on space-time independent disorder, we investigate the case of a Gaussian environment with (critically) space-correlated disorder. We show that, similarly to the independent case, a phase transition occurs: when the disorder strength is below a critical threshold, the log-partition function satisfies a central limit theorem; above this threshold, it converges to zero in distribution. Remarkably, the appropriate scaling constant for the disorder, as well as the correct limiting variance, emerge from a non-trivial induction scheme that reflects the critical nature of the correlation.

Alberto Chiarini e Sonia Mazzucchi %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Lucas Benigni (Università di Montreal) e Giorgio Cipolloni (Università di Roma 2 Tor Vergata) TITOLO: The mystery of universality in Random Matrix Theory. RIASSUNTO: Over the past fifteen years, our understanding of universality in random matrix theory has undergone a remarkable transformation. For many models of large random matrices, it is now known that both eigenvalue statistics and eigenvector structures exhibit universal behavior that depends only on the symmetry class and not on the fine details of the matrix entries. This universality lies at the heart of deep conjectures in mathematical physics—connecting topics as diverse as quantum chaos, number theory, and high-dimensional statistics—and has become one of the major success stories of modern probability theory. In this two-part colloquium, we will survey these advances with a focus on Wigner matrices, Hermitian or symmetric random matrices with i.i.d. entries up to the symmetry constraint. The first part will discuss universality of eigenvalues, from local spectral laws to modern proofs of universality of local statistics. The second part will turn to eigenvectors, highlighting recent progress on delocalization, quantum ergodicity, and eigenvector statistics.

Abstract: In this paper, we propose a unified methodology for pricing general path-dependent derivatives (e.g., Asian and Barrier options) that is based on the Monte Carlo-Conditional Fourier-cosine method and works for a broad class of stochastic volatility models. The main benefit of the proposed approach over existing literature consists in a simple and effective control of the error. A practitioner simply needs to provide the pricing algorithm with two parameters: i) a probability, q; ii) an error tolerance epsilon. Then, our proposed algorithm provides a price approximation that differs by no more than epsilon from the true unknown option price with probability at least equal to q. We provide an explicit link between the variance of the Monte Carlo simulation estimator of the option price, the error tolerance, and the number of simulations. In this way, the pricing methodology becomes extremely efficient when combined with effective variance reduction techniques that drastically reduce the number of simulations (and, consequently, the computing time) required to obtain an arbitrarily accurate price estimate.

Fabio Martinelli - Tè di Matematica a Roma Tre 29 ottobre 2025
by Pietro Caputo 22 Oct '25

22 Oct '25

Nell'ambito dei Tè di Matematica, per celebrare il pensionamento di Elisabetta Scoppola, mercoledì *29 ottobre* alle *ore 16:00*, Fabio Martinelli terrà un seminario dal titolo *"An Introduction to the Mathematical Theory of Anderson Localization"*. Abstract: In 1958, the physicist P. W. Anderson published the paper "Absence of Diffusion in Certain Random Lattices," which contributed to winning him the Nobel Prize in 1977 for the discovery of the phenomenon now known as "Anderson localization." In the simplest case, Anderson localization states that a Schroedinger operator with a random potential on, e.g., a d-dimensional lattice has a pure-point spectrum with exponentially localized eigenstates if the randomness of the potential is sufficiently strong. In his Nobel lecture Anderson said "...*Localization was a different matter: very few believed it at the time, and even fewer saw its importance; among those who failed to fully understand it at first was certainly its author. It has yet to receive adequate mathematical treatment, and one has to resort to the indignity of numerical simulations to settle even the simplest questions about it." *Proving Anderson localization was one of the great problems in mathematical physics in the early 1980s, and E. Scoppola greatly contributed to its solution in the hard case d > 1. On the occasion of her retirement, I will provide a brief overview of the Anderson model and eigenfunction localization, as well as some of the more recent developments. If time allows, I will also try to describe how the basic multiscale analysis underlying the proof of Anderson localization can be applied to other, quite different, contexts. Il seminario si svolgerà in presenza presso il Dipartimento di Matematica e Fisica dell'Università di Roma Tre, Lungotevere Dante 476, *aula M1*.

OWABI Season 7: Kick-off October 30 - FX Briol
by Massimiliano Tamborrino 16 Oct '25

16 Oct '25

Dear all, welcome back after the summer/winter break! A new season of the One World Approximate Bayesian Inference (OWABI) Seminar<https://warwick.ac.uk/fac/sci/statistics/news/upcoming-seminars/abcworldsem…> is about to start. The 1st OWABI talk of the Season will be given by François-Xavier Briol<https://fxbriol.github.io/> (University College London). who will talk about "Multilevel neural simulation-based inference<https://arxiv.org/abs/2506.06087>" on Thursday the 30th October at 11am UK time. We are pleased to announce that FX Briol has also joined the OWABI Organiser Team. Abstract: Neural simulation-based inference (SBI) is a popular set of methods for Bayesian inference when models are only available in the form of a simulator. These methods are widely used in the sciences and engineering, where writing down a likelihood can be significantly more challenging than constructing a simulator. However, the performance of neural SBI can suffer when simulators are computationally expensive, thereby limiting the number of simulations that can be performed. In this paper, we propose a novel approach to neural SBI which leverages multilevel Monte Carlo techniques for settings where several simulators of varying cost and fidelity are available. We demonstrate through both theoretical analysis and extensive experiments that our method can significantly enhance the accuracy of SBI methods given a fixed computational budget. Keywords: Multifidelity, neural SBI, multi-level Monte Carlo The talk will be streamed on MS Teams: Join the meeting now<https://teams.microsoft.com/l/meetup-join/19%3adhZ_4e_XLNJzCXPAMzTvT6BZ5KSh…> Meeting ID: 358 173 458 006 0 Passcode: Vp2975vC We are looking forward to seeing you all, best, Massimiliano on the behalf of the OWABI Organisers ------ Dr. Massimiliano Tamborrino Reader (Associate Professor) and WIHEA Fellow Department of Statistics University of Warwick https://warwick.ac.uk/tamborrino
