Buongiorno a tutti, Vorremmo segnalarvi che venerdì prossimo (19 Gennaio) alle ore 14:30 in aula 1BC50 (Torre Archimede, Università di Padova) ci sarà un seminario per il ciclo di seminari in Probabilità e Finanza di: Francesco Pedrotti (Institute of Science and Technology Austria) <https://sites.google.com/view/francescopedrotti/home-page?authuser=0> https://sites.google.com/view/francescopedrotti/home-page?authuser=0 Title: Contractive coupling rates and curvature lower bounds for reversible Markov chains Date: January 19, 2024, at 14:30, room 1BC45 Abstract: Ricci curvature lower bounds for Riemannian manifolds have been linked to many functional inequalities: this has motivated the seminal independent works of Sturm and Lott and Villani, who extended the notion of curvature lower bound and many of its consequences to a large class of metric measure spaces. In spite of its generality, this theory does not apply to Markov chains on discrete spaces; for this reason, several adapted notions of curvature have been proposed, based on different equivalent characterizations of curvature of Riemannian manifolds. Different notions have different pros and cons: e.g., the entropic curvature of Erbar and Maas is hard to compute in some examples, while Olliviers coarse Ricci curvature is not known to imply a modified logarithmic Sobolev inequality. It is still an open problem to compare these notions. In the present work, adapting arguments of a recent article by Conforti, we show how contractive coupling rates (a concept naturally connected to Olliviers curvature) can be used to establish entropic curvature lower bounds for some examples of reversible Markov chains. Vi aspettiamo numerosi! Alberto Chiarini e Alekos Cecchin Sito web del seminario: https://www.math.unipd.it/~chiarini/seminars/

15 Jan '24

Dear all, a kind reminder that the deadline for the abstract submission for contributed talks or poster at BioInference2024 (5th -7th June at Warwick https://bioinference.github.io/2024/) is quickly approached, being it on the 31st January 2024. If you are interested on mathematical modelling and statistical methods for (widely defined/interpreted) biological problems, then please consider submitting an abstract here forms.gle/SBawnWD3k8iSS1Vt6<http://forms.gle/SBawnWD3k8iSS1Vt6> More info are reported below. Best, Massi on the behalf of the BioInference2024 organising committee ------------------------------------ The BioInference 2024 conference (https://bioinference.github.io/2024/) is taking place at the University of Warwick on the 5th-7th June 2024, and it will combine a data-driven meeting on day 1 (registration fee: £30) with the main two-day conference on the 6th and 7th June 2024 (registration fee: £70). Launched in 2022, BioInference aims to bring together researchers from across statistics and mathematical modelling who work with biological systems, and from all career stages, to foster discussions between the two communities and to prompt collaborations. The talks from the two previous BioInference conferences are available via our public YouTube channel (youtube.com/@bioinference5299<http://youtube.com/@bioinference5299>). The two-day conference will combine contributed talks and poster sessions. We now invite abstracts for oral/poster presentations on work either relating to statistical methods development (so long as those methods are applicable to biological systems) or on the application of statistical methods to solve biological problems. All presentations will be in-person. Abstracts can be submitted via a Google form (forms.gle/SBawnWD3k8iSS1Vt6<http://forms.gle/SBawnWD3k8iSS1Vt6>) and the deadline is on the 31st January 2024. It is our pleasure to confirm that this year's invited speakers are: * Alex Browning<https://alexbrowning.me/>, University of Oxford * Sarah Filippi<https://www.imperial.ac.uk/people/s.filippi>, Imperial College London * Hong Ge<https://mlg.eng.cam.ac.uk/hong/>, University of Cambridge * Hamid Rahkooy<https://people.maths.ox.ac.uk/rahkooy/bio.html>, University of Oxford * Heba Sailem<https://www.hebasailem.com/>, King’s College London * Catalina Vallejos<https://www.ed.ac.uk/mrc-human-genetics-unit/research/vallejos-group>, University of Edinburgh The conference organising committee is committed to ensuring fair participation of individuals across all career stages, genders, races and ethnicities, ages, geographic locations, and universities. Data-driven meeting: problems and methodologies This year, we are also running an optional event on the 5th June at Warwick before the main conference starts. This aims to bring together mathematicians, statisticians and those who possess or generate datasets and would like to analyse them/answer some open questions. These may include biologists, clinicians etc in academia and industry. The idea of this meeting is to think about potential solutions to these data-based problems, gathering interest for possible collaborations between individuals across disciplines, institutions and career stages. The day would consist of a range of presentations by the experimental/business partners in the morning, and focus/discussion groups in the afternoon, aiming to start formulating an action plan to tackle the open challenges. The cost of attending day one is £30 in addition to the registration fee for the main conference.

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 19 Gennaio 2024, alle ore 12.00, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Speaker: Francesca Crucinio (ENSEAE, France) Title: *A connection between tempering and entropic mirror descent* Abstract: This talk explores the connections between tempering (for Sequential Monte Carlo; SMC) and entropic mirror descent to sample from a target probability distribution whose unnormalized density is known. We establish that tempering SMC is a numerical approximation of entropic mirror descent applied to the Kullback-Leibler (KL) divergence and obtain convergence rates for the tempering iterates. Our result motivates the tempering iterates from an optimization point of view, showing that tempering can be used as an alternative to Langevin-based algorithms to minimize the KL divergence. We exploit the connection between tempering and mirror descent iterates to justify common practices in SMC and propose improvements to algorithms in literature. ------------------------------------------------ Sarà possibile seguire il seminario anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/85042791274?pwd=V05aejBLYXEyL1lRNURFMUZIcy9PUT09> Il seminario è organizzato 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/>

Seminario di Michele Salvi alla Sapienza, Martedì 16/01/24
by Faggionato, Alessandra 11 Jan '24

11 Jan '24

Buongiorno Martedì 16 Gennaio Michele Salvi terrà un seminario di Probabilità al Dipartimento di Matematica della Sapienza Sotto trovate i dettagli. Grazie per l'attenzione Saluti Alessandra %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Speaker: Michele Salvi (Università di Tor Vergata) Where: Sala di Consiglio, Dip. di Matematica, Sapienza Università di Roma When: Tuesday 16 January, 14:00 (sharp) Title: *From the Uniform to the Minimum Spanning Tree* Abstract: A spanning tree of a graph G is a connected subset of G without cycles. The *Uniform Spanning Tree* (UST) is obtained by choosing one of the possible spanning trees of G at random. The *Minimum Spanning Tree* (MST) is realised instead by putting random weights on the edges of G and then selecting the spanning tree with the smallest weight. These two models exhibit markedly different behaviours: for example, their diameter on the complete graph with n nodes transitions from n^1/2 for the UST to n^1/3 for the MST. What lies in between? We introduce a model of *Random Spanning Trees in Random Environment* (RSTRE) designed to interpolate between UST and MST. In particular, when the environment disorder is sufficiently low, the RSTRE on the complete graph has a diameter of n^1/2 as the UST. Conversely, when the disorder is high, the diameter behaves like n^1/3 as for the MST. We conjecture a smooth transition between these two values for intermediate levels of disorder. This talk is based on joint work with Rongfeng Sun and Luca Makowiec (NUS Singapore). -- ************************************************* Prof. Alessandra Faggionato https://www1.mat.uniroma1.it/people/faggionato/ Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome Office 5, Phone (0039) 06 49913252 *************************************************
