Seminario Hakima Bessaih - Politecnico di Milano - 30 Maggio 2025
by Luca Scarpa 26 May '25

26 May '25

Si segnala il seguente seminario a tutti gli interessati. Venerdì 30 Maggio 2025, ore 11:00. Aula Seminari III Piano, Dipartimento di Matematica, Politecnico di Milano. Speaker: Hakima Bessaih, Florida International University. Title: Synchronization in Stochastic Systems: Models and Applications Abstract: Synchronization phenomena describe the long-time behavior of systems composed of interacting particles or agents that eventually reach a common state. In this talk, we will present several stochastic models and investigate their synchronization properties under both additive and multiplicative noise. We will also explore an application to networked systems, modeled by stochastic reaction-diffusion equations on a graph.

OWABI@BioInference2025 - 29th May 10am UK time
by Massimiliano Tamborrino 26 May '25

26 May '25

Dear all, the next OWABI www.warwick.ac.uk/owabi<http://www.warwick.ac.uk/owabi> seminar is quickly approaching, with two talks live from BioInference 2025 (https://bioinference.github.io/2025/). The seminars will be on Thursday the 29th May, at 10am UK time (note the different time with respect to previous seminars), given by * Andrew Golightly (Durham University), Accelerating Bayesian inference for stochastic epidemic models using incidence data * Henrik Häggström (Chalmers University), Simulation-based inference for stochastic nonlinear mixed-effects models with applications in systems biology with abstracts reported below. The talks will be streamed on the OWABI MS Team Channel<https://teams.microsoft.com/l/team/19%3AdhZ_4e_XLNJzCXPAMzTvT6BZ5KShEETkd_w…> <https://teams.microsoft.com/l/team/19%3AdhZ_4e_XLNJzCXPAMzTvT6BZ5KShEETkd_w…> , at the link https://teams.microsoft.com/l/meetup-join/19%3adhZ_4e_XLNJzCXPAMzTvT6BZ5KSh… Meeting ID: 323 917 219 730 3 Passcode: Fk9JG3eB 1st OWABI Talk: 10-10.30am UK time Speaker: Andrew Golightly<https://www.durham.ac.uk/staff/andrew-golightly/> (Durham University) Title: Accelerating Bayesian inference for stochastic epidemic models using incidence data Abstract: This work considers the case of performing Bayesian inference for stochastic epidemic compartment models, using incomplete time course data consisting of incidence counts that are either the number of new infections or removals in time intervals of fixed length. The most natural Markov jump process representation of the model is eschewed for reasons of computational efficiency, and replaced by a stochastic differential equation representation. This is further approximated to give a tractable Gaussian process, that is, the linear noise approximation (LNA). Unless the observation model linking the LNA to data is both linear and Gaussian, the observed data likelihood remains intractable. Unlike previous approaches that use the LNA in this setting, two approaches for marginalising over the latent process are considered: a correlated pseudo-marginal method and analytic marginalisation via a Gaussian approximation of the noise model. These approaches are compared using synthetic data with the best performing method applied to real data consisting of removal incidence of Oak Processionary moth nests in Richmond Park, London. 2nd Seminar: 10.30-11am UK time Speaker: Henrik Häggström<https://research.chalmers.se/en/person/henhagg> (Chalmers University) Title: Simulation-based inference for stochastic nonlinear mixed-effects models with applications in systems biology Abstract: We propose a novel methodology for Bayesian inference in hierarchical mixed-effects models. By building on our work [1], we construct a simulation-based inference (SBI) framework that is highly scalable, where amortized approximations to the likelihood and the parameters posterior are first obtained, and these are rapidly refined for each individual dataset, to ultimately approximate the parameters posterior across many individuals. Unlike the current state-of-art SBI methods, which use neural networks, our approximations are expressed via Gaussian mixture models, leading to easily trainable, parsimonious yet expressive surrogate models of both the likelihood function and the posterior distribution. The methodology is exemplified via stochastic differential equation mixed-effects models to describe translation kinetics after mRNA transfection, however the methodology is general and can accommodate other types of stochastic and deterministic models. We compare our approximate inference with exact pseudomarginal inference and show that our methodology is fast and competitive. We are looking forward to seeing you at the next OWABI seminar(s), 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

Seminar Alfred Galichon Thu 29 May 14:30
by Marta Catalano 22 May '25

22 May '25

Dear all, we are pleased to announce the following seminar at Luiss University. ——— Speaker: Alfred Galichon, New York University Title: Optimal Transport for Economics: Applications and Extensions When: Thu May 29, 14:30 Where: Via Lisbona 7, 00198 Roma Room: S03A Abstract: Optimal transport theory has emerged as a unifying geometric framework for a wide range of economic questions that hinge on allocating heterogeneous agents or goods in a cost-efficient way. This talk surveys recent methodological advances and shows how they sharpen three core empirical tools: - Discrete choice models – I will show how viewing demand estimation through the lens of optimal transport delivers transparent identification of taste heterogeneity and suggests computationally efficient estimation algorithms that scale to high-dimensional product spaces. - Matching models – Building on the Monge–Kantorovich formulation, I will discuss equilibrium assignments in labor and marriage markets, highlighting new existence and uniqueness results when complementarities are non-transferable. Optimal transport duality provides constructive characterizations of wage/transfer schedules and illuminates comparative-statics of policy interventions. - Quantile regression and distributional methods – Re-casting quantile regression as an optimal transport problem links conditional quantiles to integral probability metrics. This perspective leads to robust, dependence-aware estimators and facilitates inference on counterfactual distributions, with applications to wage inequality and treatment-effect heterogeneity. Throughout, I will emphasize common geometric intuition, outline open computational challenges, and sketch extensions to dynamic settings and strategic interaction. The overarching goal is to demonstrate how optimal transport offers economists a versatile, tractable, and conceptually coherent toolkit for modeling heterogeneity and market frictions across disparate empirical domains. ——— More info can be found at this link: https://economiaefinanza.luiss.it/research-seminar/optimal-transport-for-ec… The seminar will be in presence only.
