OWABC evolves into OWABI - Kick off talk October 31st
by Massimiliano Tamborrino 23 Oct '24

23 Oct '24

Dear all, After 5 Seasons of the One World Approximate Bayesian Computation (ABC) Seminar<https://warwick.ac.uk/fac/sci/statistics/news/upcoming-seminars/abcworldsem…>, launched in April 2020 to gather members and disseminate results and innovation during those weeks and months under lockdown, we have now decided to launch a "new" seminar series, the One World Approximate Bayesian Inference (OWABI) Seminar<https://warwick.ac.uk/fac/sci/statistics/news/upcoming-seminars/abcworldsem…>, to better reflect the broader interest and scope of this series, which goes beyond ABC. In particular, simulation-based inference and ML related techniques will play a crucial role. We are also please to announce that Stefan Radev<https://faculty.rpi.edu/stefan-radev> <https://faculty.rpi.edu/stefan-radev> has joined the OWABI Organiser Team. The 1st OWABI talk will be given by Ullrich Koethe<https://hci.iwr.uni-heidelberg.de/vislearn/people/ullrich-koethe/> (University of Heidelberg), who will talk about "Free-form flows for physics-informed generative modeling" on Thursday the 31st October at 11am UK time. Abstract: The talk first introduces a useful categorization of the (sometimes confusing) "generative model zoo" in terms of different change-of-variables formulas. It then shows how normalizing flows, a major architecture for generative neural networks, can be used for simulation-based Bayesian inference in the sciences. Finally, it proposes free-form flows to simplify the incorporation of physical prior knowledge, e.g. rotation and translation invariance or the restriction of the distribution to a manifold, into generative models. Keywords: normalizing flows; physical-informed neural networks; simulation-based inference 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: 394 858 339 716 Passcode: qLKarj 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

Fwd: [dynlist] Mini-course Prof. Michael Yampolsky (first lecture)
by Stefano Marmi 22 Oct '24

22 Oct '24

Dear all, a gentle reminder of the mini-course by Michael Yampolsky. It will be also possible to follow the lectures remotely at the link given in the message below. Kind regards Stefano Marmi Dear all, In the next few weeks Prof. Michael Yampolsky (University of Toronto Mississauga) will give a series of 4 lectures on*“Computability and Computational Complexity Questions in Dynamics”* at the Scuola Normale Superiore in Pisa. The lectures will take place on Thursdays October 24 and 31 and November 7 and 14, at* 4:30* pm in* Aula Volterra*, Piazza dei Cavalieri 7 and will be streamed online. Please find below the title and abstract of the first lecture (Thursday October 24) and the relative zoom link. *October 24:* *Computability and computational complexity in dynamics: can we trust numerical predictions of limiting behavior of orbits?* The development of the modern subject of dynamical systems went hand-in-hand with numerical modeling. However, the theoretical basis of such modeling has remained largely unexplored and offers exciting challenges. What can and cannot be computed about the behavior of a dynamical system? I will give an overview of some of the recent results and directions of study. *Zoom link* : https://us02web.zoom.us/j/87207701292?pwd=cS85dXl0WC9udDhJNmkrd3FQVDJhdz09 Below you can find titles and abstracts of the next lectures. *October 31:* *Don’t believe your lying eyes: (non)-computability of Julia sets.* The talk will be a deep dive into the question of computability and computational complexity of Julia sets. Their fractal images are among the most-computed pictures in all of mathematics. But can we trust what these computations show? The results are surprising, and involve some beautiful complex analysis. The talk will be based on my work with M. Braverman, as well as more recent results obtained with A. Dudko, C. Rojas, and others. *November 7:* *How to lose at Monte Carlo: computing statistical behavior of dynamical systems.* Introduced by Ulam and von Neumann in the 1940s, Monte Carlo technique remains the most ubiquitous tool for statistical modeling. Surprisingly, our recent work with C. Rojas shows that such modeling probably fails for some very simple dynamical systems. I will present this theorem and discuss the resulting mathematical challenges. *November 14:* *Thurston versus Turing: algorithmic hardness of classifying finite dynamical systems.* Historically, the algorithmic aspects of classification problems have motivated much of the research in geometric topology (knot theory, classification of surfaces and 3-manifolds, etc). These questions are also very fruitful in dynamics. I will discuss the joint results with N. Selinger, K. Rafi and others on algorithmic decidability of Thurston equivalence and the connection with geometrization questions in dynamics.

SPASS Seminar: Lars Schroeder
by Gianmarco Bet 21 Oct '24

21 Oct '24

Dear Colleagues, We would like to invite you to the following SPASS seminar, jointly organized by UniPi, SNS, UniFi and UniSi (abstract below): *Stationary distribution of node2vec random walks on household models* by *Lars Schroeder* (University of Twente) The seminar will take place on *TUE, 22.10.2024* at* 11:00 CET* in Aula Tricerri, Dipartimento di Matematica e Informatica "Ulisse Dini", UNIFI and streamed online at this link <https://meet.google.com/gji-phwo-vbg>. The organizers, A. Agazzi, G. Bet, A. Caraceni, F. Grotto, G. Zanco https://sites.google.com/unipi.it/spass <https://www.google.com/url?q=https://sites.google.com/unipi.it/spass&source…> -------------------------------------------- *Stationary distribution of node2vec random walks on household models* *Abstract: node2vec random walks are tuneable random walks that come from the popular computer science algorithm node2vec which is used for feature learning on networks. The transition probabilities of the random walks depend on the previous visited node and on the triangles that contain the current and the previous node. Even though the algorithm is very popular in the field of computer science, mathematical properties of the random walks almost have not been explored. We will present results on the stationary distribution of these random walks on household models and compare it with the simple random walk.*

Seminars in Statistics - Beatrice Acciaio (ETH Zurich)

20 Oct '24

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Martedi 22 Ottobre 2024, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ *12.00-13.00* Speaker: Beatrice Acciaio (ETH Zurich) Title: *Stretched Brownian Motion and Bass local-volatility model* Abstract: The concept of stretched Brownian motion (SBM) has been introduced by Backhoff-Veraguas et al (2020) as the unique solution to a dynamic formulation of the martingale transport problem. The name originates from the characteristic of mimicking as closely as possible the movement of a Brownian particle, while fitting the prescribed marginals. Conze and Henry-Labordere (2021) suggested a fixed-point iteration scheme for the computation of the SBM. In this talk I will review fundamental results for the SMB and provide convergence results of the fixed-point iteration. This constitutes the building block for the computation of the Bass local volatility model, which is a Markov model perfectly calibrated to vanilla options for finite maturities, and an approximation of the Dupire local volatility model. [Based on a joint work with A. Marini and G. Pammer.] ------------------------------------------------ Sarà possibile seguire entrambi i seminari anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/85297679121?pwd=LBx0D9qCgMil8TYPZzR6bXKyAleCgR.1> I seminari sono organizzati dalla "de Castro" Statistics Initiative www.carloalberto.org/stats -- Pierpaolo De Blasi University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>

Buongiorno, ricevo e con piacere inoltro. Saluti Alessandra ---------- Forwarded message --------- From: Inhomegenous Random <inter(a)math.cnrs.fr> Date: Sun, 20 Oct 2024 at 16:29 Subject: January 28-29 IRS 2025 Conference Announcement To: <faggiona(a)mat.uniroma1.it> Dear Colleagues, This is the first announcement for the two-day conference on: INHOMOGENEOUS RANDOM SYSTEMS which will be held on Tuesday 28 and Wednesday 29 January 2025 at Institut Henri Poincaré, Paris. You will find in attachment a PDF file of the announcement with the same informations as below which you may print and post up. Looking forward to meeting you in Paris, Christian Maes, Kirone Mallick, Ellen Saada. --------------------------------------------------------------------- INHOMOGENEOUS RANDOM SYSTEMS Systemes Aleatoires Inhomogenes January 28-29, 2025 Institut Henri Poincaré 11-13, rue Pierre et Marie Curie, Paris The aim of this annual workshop is to bring together mathematicians and physicists working on disordered or random systems, and to discuss recent developments on themes of common interest. Each of the two days is devoted to a specific topic; the 2025 session is planned as follows. Tuesday 28 January: SPIN GLASSES AND RELATED TOPICS. Moderator: Jean-Christophe Mourrat (Lyon). Spin glasses are models of statistical mechanics characterized by disordered interactions and complex energy landscapes. They serve as fundamental examples of complex systems, providing insights into various scientific fields. This event will bring together different perspectives from mathematics, physics, and computer science, showcasing recent developments and promising research directions. Speakers: Leticia Cugliandolo (Paris), Brice Huang (Boston), Antoine Maillard (Paris), Remi Monasson (Paris), Guilhem Semerjian (Paris), Eliran Subag (Rehovot), Pierfrancesco Urbani (Saclay). Wednesday 29 January: ERGODICITY-BREAKING PHENOMENA IN QUANTUM MECHANICS. Moderator: Wojciech De Roeck (Leuven) Experimental marvels like cold atoms are allowing us to probe many-body Hamiltonian dynamics in a very detailed way, bringing into focus questions that might have seemed almost philosophical in earlier decades. One of the surprises from these experiments is that such systems often fail to thermalize. Phenomena like `localization', `quantum scars' and various types of glassy behaviour are ubiquitous in these simple quantum systems, whereas they do not seem so common in condensed matter platforms. This day brings together several specialists from this field. Speakers: Marin Bukov (Dresden), François Huveneers (London), Andrea De Luca (Cergy), David Luitz (Bonn), Markus Mueller (Vienna), Silvia Pappalardi (Koeln), Simone Warzel (Muenchen). --------------------- The conference is free and open to all.
