SPASS Seminar: Filippo Quattrocchi
by Francesco Grotto 12 Dec '24

12 Dec '24

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi: *Asymptotics for quantization of probability measures * by Filippo Quattrocchi (IST Austria) The seminar will take place TUE, 17.12.2024 at 11:00 CET in Aula Riunioni, Dipartimento di Matematica, UNIPI and streamed online at the link below. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass *---------------------------------------------------------* *Abstract: * Quantization is the problem of approximating a given probability measure using discrete measures, supported on a prescribed number n of points. One of the fundamental questions is: At what rate does the minimal quantization error (measured in Wasserstein distance) tend to 0 as n grows? A classical answer is given by Zador's theorem. I will discuss this result along with some new findings on a variation of the problem, in which the discrete approximating measures are additionally constrained to be uniform. This talk is based on the work arXiv:2408.12924.

Seminario di Ivailo Hartarsky alla Sapienza
by Faggionato, Alessandra 09 Dec '24

09 Dec '24

Buongiorno, la prossima settimana Ivailo Hartarsky (ENS, Lione) sarà ospite del Dipartimento di Matematica dell'Università La Sapienza. Lunedì 16 terrà un seminario. Sotto trovate i dettagli. Grazie Saluti Alessandra %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% When: Monday 16 December, 16:00. Room: Sala di Consiglio, Department of Mathematics, Sapienza University of Rome Speaker: Ivailo Hartarsky (ENS, Lyon) Title: Catalan percolation Abstract: In Catalan percolation, one declares the edges {i,i+1}, for integer i, *occupied* and each edge {i,j} with j> i+1 *open* independently with probability p. For k> i+1, we recursively define {i,k} to be *occupied*, if {i,k} is open and both {i,j} and {j,k} are occupied for some j in {i+1,...,k-1}. The model was introduced by Gravner and Kolesnik in the context of polluted bootstrap percolation, but is tightly linked with Catalan structures and oriented percolation. We establish that the critical parameter of the model is strictly between the natural lower and upper bounds given by 1/4 and the critical probability of oriented site percolation on Z^2 respectively. The most challenging part of the proof is a strict inequality for the critical parameter of an oriented percolation model with non-decaying infinite range dependencies, not relying on the Aizenman--Grimmett argument for essential enhancements. The talk is based on joint work with Eleanor Archer, Brett Kolesnik, Sam Olesker-Taylor, Bruno Schapira and Daniel Valesin available at https://arxiv.org/abs/2404.19583. -- ************************************************* 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 *************************************************

Seminari Padova - Pablo Lopez Rivera e Nicolas Agote
by alekos.cecchin＠unipd.it 06 Dec '24

06 Dec '24

Buongiorno a tutti, Vorremmo segnalarvi che venerdì prossimo (13 Dicembre) in aula 2BC30 (Torre Archimede, Università di Padova) ci saranno due seminari per il ciclo di seminari in Probabilità e Finanza di: 1) Pablo López Rivera (Université Paris Cité) <https://www.ljll.fr/lopezrivera/> https://www.ljll.fr/lopezrivera/ Title: Functional inequalities in the discrete setting and the Poisson-Föllmer Process Date: December 13, 2024, at 14:30, room 2BC30 Abstract: Functional inequalities are a ubiquitous tool in probability, since they help us quantify the convergence to equilibrium of ergodic Markov processes and imply good concentration properties. In the continuous setting, the Gaussian measure is a central object, since it satisfies both a Poincaré and a log-Sobolev inequality. In particular, Caffarelli's contraction theorem states that the optimal transport map pushing forward the Gaussian towards a measure which is more log-concave than it is 1-Lipschitz, a fact that allows us to extend these inequalities to those measures. Can we prove an analogous result in the discrete setting if we replace the Gaussian by the Poisson distribution? The type of measures that can arise as a pushforward of a discrete distribution is very limited; in addition, the lack of a chain rule in the discrete setting hinders the argument used in the continuous setting. In the first part of the talk, I will show how these obstacles can be overcome via a stochastic proof based on an entropy-minimizing process constructed by Klartag and Lehec, which we call the Poisson-Föllmer process. In the second part of the talk I will also use this process to give a stability result for Wu's log-Sobolev inequality, the Poissonan analog of the Gaussian one.. 2) Nicolas Agote (Universidad de Buenos Aires) Title: The potential method for community detection Date: December 13, 2024, at 15:30, room 2BC30 Abstract: The Stochastic Block Model (SBM) is a random graph model where nodes are (randomly) partitioned into classes, or communities, which share a common label, and edges are (randomly) added between each pair of nodes depending on their community membership. It is a very popular model to study the community detection problem, where the aim is to predict the communities given a sample graph. In this talk we will explore the potential estimators, which exploit information obtained via random walks, specifically expected first visit times to some subset of revealed nodes, to predict the community structure. We will show that they allow for strongly consistent and efficient estimations, particularly for small subsets of nodes. This work has been done in collaboration with Inés Armendáriz (UBA), Pablo Ferrari (UBA), and Florencia Leonardi (USP). Vi aspettiamo numerosi!

Seminars in Statistics at Collegio Carlo Alberto - S. Pulido (ENSIIE) and K. Ray (Imperial College London)
by Matteo Giordano 06 Dec '24

06 Dec '24

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.google.com/url?q=https://www.carloalberto.org/events/category/s…> Venerdì 13/12/2024, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente doppio seminario: ------------------------------------------------ 11.00-12.00 Speaker: Sergio Pulido (ENSIIE) Title: Polynomial Volterra processes Abstract: Recent studies have extended the theory of affine processes to the stochastic Volterra equations framework. In this talk, I will describe how the theory of polynomial processes extends to the Volterra setting. In particular, I will explain the moment formula and an interesting stochastic invariance result in this context. Potential applications to fractional volatility models will be discussed. This is joint work with Eduardo Abi Jaber, Christa Cuchiero, Luca Pelizzari and Sara Svaluto-Ferro. 12.00-13.00 Speaker: Kolyan Ray Title: Bayesian nonparametric inference in a McKean-Vlasov model Abstract: We study nonparametric estimation of the interaction term in a McKean-Vlasov model where noisy observations are drawn from the nonlinear parabolic PDE arising in the mean-field limit as the number particles grows to infinity. In this model, the long-time invariant state can be uninformative about the interaction potential. We therefore show that under certain regularity conditions on the initial state, the short-time behaviour of this system contains sufficient information to consistently recover the interaction potential using Gaussian process priors. This involves establishing a stability-type estimate for this PDE to solve the resulting inverse problem. ------------------------------------------------ Sarà possibile il seminario anche in streaming: chiunque volesse collegarsi è pregato di inviare una email entro *mercoledì 11/12/2024 * 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 PRISMA oggi
by Francesco Caravenna 03 Dec '24

03 Dec '24

Seminari on-line del gruppo UMI - PRISMA (http://www.umi-prisma.polito.it/) Ricordiamo che oggi, martedì 3 dicembre 2024, Sonia Mazzucchi e Stefano Bonaccorsi (Università di Trento) ci parleranno di Passeggiate casuali sul piano complesso ed equazioni del calore di ordine superiore al secondo con il seguente orario: 16:00 Primo seminario 16:30 Pausa e discussione 16:45 Secondo seminario 17:15 Conclusione e discussione Trovate di seguito il riassunto. I seminari verranno trasmessi via Zoom al seguente link: https://uniroma1.zoom.us/j/88679569146 Meeting ID: 886 7956 9146 Vi aspettiamo numerosi! Valentina Cammarota e Francesco Caravenna %%%%%%%%%%%%%%%%%%%%%%%%%%%% RELATORI: Sonia Mazzucchi (Università di Trento) e Stefano Bonaccorsi (Università di Trento) TITOLO: Passeggiate casuali sul piano complesso ed equazioni del calore di ordine superiore al secondo RIASSUNTO: La celebre formula di Feynman-Kac, che fornisce una rappresentazione della soluzione dell'equazione del calore in termini di un integrale rispetto alla misura di Wiener, non può essere generalizzata al caso in cui il laplaciano, o più in generale l'operatore ellittico del secondo ordine, è sostituito da un operatore di ordine superiore a 2. In altre parole per tale classe di equazioni differenziali di ordine elevato non è possibile costruire un processo stocastico che svolga lo stesso ruolo giocato dal moto Browniano per l'equazione del calore. Nella prima parte del seminario si illustreranno dapprima le ragioni di questo risultato no-go per poi descrivere un possibile metodo per aggirarlo tramite la costruzione di opportune successioni di passeggiate casuali nel piano complesso. Nella seconda parte del seminario si descriveranno ulteriori applicazioni e generalizzazioni di tale tecnica. In particolare si illustrerà la costruzione di un calcolo stocastico associato alla successione di passeggiate casuali e la dimostrazione di formule di Feynman-Kac per PDE di ordine elevato, anche nel caso di derivate di tipo frazionario. %%%%%%%%%%%%%%%%%%%%%%%%%%%% I seminari PRISMA hanno un formato di "colloquium" per creare un'occasione di scambio e discussione con tutta la comunità dei probabilisti e statistici italiani. Ogni giornata comprende due relatori che tengono due seminari di 30 minuti strettamente connessi, per presentare alla comunità una prospettiva sul proprio ambito di ricerca. Da quest'anno le registrazioni dei seminari vengono pubblicate sul canale YouTube dell'UMI: https://youtube.com/playlist?list=PLmySpc-jrtAMq84VH71evyqPc1hl6eEQb %%%%%%%%%%%%%%%%%%%%%%%%%%%%

Algebra meets probability: workshop
by Cipriani, Alessandra 02 Dec '24

02 Dec '24

Dear colleagues, registration is now open for the workshop "Algebra meets probability" taking place between March 31 and April 2, 2025 at EURANDOM at Eindhoven University of Technology. There is a natural and well-known connection between particle physics and representation theory via Grassmannian and Lie algebras, going back to Wigner. Specific algebraic structures, such as Virasoro algebras, are used in lattice models to describe symmetries and conservation laws. These structures help in understanding the behavior of systems at a microscopic level and in deriving macroscopic properties from microscopic rules. In recent years there has been tremendous progress in connecting these two approaches and expressing observables like k-point correlation functions in interacting particle systems in terms of algebraic quantities, for example as fermionc and bosonic variables. This event aims to bring together leading experts and researchers in the field to share their knowledge, insights, and recent advancements. The workshop will provide a platform for in-depth discussions and collaborative learning, fostering an environment where participants can exchange ideas and develop new perspectives on the interplay between these two fascinating areas of study. Speakers: David Adame-Carrillo (Aalto University) Francesca Arici (Leiden University) Chiara Boccato (University of Pisa) Martijn Caspers (TU Delft) Nicholas Crawford (Technion, Haifa) Margherita Disertori (Bonn University) Tyler Helmuth (Durham University) Bas Janssens (TU Delft) Kalle Kytölä (Aalto University) Yves Le Jan (NYU Abu Dhabi) Franz Merkl (TU München) Eveliina Peltola (TBC) (Aalto University) Silke Rolles (TU München) Walter van Suijlekom (Radboud University Nijmegen) Pierre Tarrès (NYU Shanghai) More details and the registration can be found on the conference website.<https://www.eurandom.tue.nl/event/algebra-meets-probability/> There is no registration fee and the possibility to present a poster.

Short course - Kolyan RAY (Imperial)
by Matteo Ruggiero 28 Nov '24

28 Nov '24

Dear Colleagues, as part of the Visiting Professors program of the Master's Degree in Stochastics and Data Science at the University of Torino (full program available at https://www.master-sds.unito.it/go/visiting) we are pleased to announce the following short course: ——————————————————— Kolyan RAY (Imperial College London) POSTERIOR ASYMPTOTICS IN BAYESIAN NONPARAMETRICS This mini-course will cover an introduction into the asymptotic theory for Bayesian nonparametric procedures. This provides a useful tool to understand how prior choices can affect the statistical performance of the Bayes method in high or infinite dimensional models. We will cover the notion of posterior consistency and convergence rates, using Gaussian process priors as a canonical example. At the end, we will also touch on recent extensions of such theory to variational Bayes, which provides a scalable posterior approximation algorithm. ——————————————————— The course will be held exclusively in-person, according to the following schedule: - Tue Dec 10, h. 9.15-11.15 - Wed Dec 11, h. 11.15-13.00 - Thu Dec 12, h. 9.15-11.15 - Thu Dec 12, h. 14.00-16.00 Course location: Room 30, third floor, Corso Unione Sovietica 218/bis, 10134, Torino. The participation is open to everyone interested. Best regards, Matteo Ruggiero --- Matteo Ruggiero University of Torino and Collegio Carlo Alberto www.matteoruggiero.it

28 Nov '24

Buongiorno a tutti, Vorremmo segnalarvi che venerdì prossimo (29 Novembre) alle ore 14:30 in aula 2BC30 (Torre Archimede, Università di Padova) ci sarà un seminario per il ciclo di seminari in Probabilità e Finanza di: Alex Delalande (EPFL Losanna) https://alex-delalande.github.io Title: Sharper Exponential Convergence Rates for Sinkhorn's Algorithm in Continuous Settings Date: November 29, 2024, at 14:30, room 2BC30 Abstract: In this talk, I will present recent results I obtained in collaboration with Lénaïc Chizat and Tomas Vaškevičius regarding the convergence rate of Sinkhorn's algorithm for solving entropy-regularized optimal transport problems, in the context where at least one of the probability measures, say \mu, admits a density over \R^d. For a semi-concave cost function bounded by c∞ and a regularization parameter λ>0, we obtained exponential convergence guarantees on the dual sub-optimality gap with contraction rates that are polynomial in λ/c∞. This represents an exponential improvement over the known contraction rate 1−Θ(exp(−c∞/λ)) achievable via Hilbert's projective metric. Specifically, we proved a contraction rate value of 1−Θ(λ²/c²∞) when has a bounded log-density. In some cases, such as when is log-concave and the cost function is c(x,y)=−⟨x,y⟩, this rate improves to 1−Θ(λ/c∞). The latter rate matches the one that we derived for the transport between isotropic Gaussian measures, indicating tightness in the dependency in λ/c∞. Our results are fully non-asymptotic and explicit in all the parameters of the problem. Vi aspettiamo numerosi!

Carlo Ciliberto at Tor Vergata 03.12
by Michele Salvi 26 Nov '24

26 Nov '24

Dear all, On Tuesday, December 3rd, at 14h00 in Aula Dal Passo of Tor Vergata Math Department, RoMaDS (https://www.mat.uniroma2.it/~rds/events.php) will host Carlo Ciliberto (University College London) with the seminar “Operator World Models for Reinforcement Learning” Abstract: Policy Mirror Descent (PMD) is a powerful and theoretically sound methodology for sequential decision making. However, it is not directly applicable to Reinforcement Learning (RL) due to the inaccessibility of explicit action-value functions. We address this challenge by introducing a novel approach based on learning a world model of the environment using conditional mean embeddings. Leveraging tools from operator theory we derive a closed-form expression of the action-value function in terms of the world model via simple matrix operations. Combining these estimators with PMD leads to POWR, a new RL algorithm for which we prove convergence rates to the global optimum. Preliminary experiments in finite and infinite state settings support the effectiveness of our method. We encourage in-person partecipation.
