OWABI@BioInference2025 - today at * 10.30am * UK time
by Massimiliano Tamborrino 29 May '25

29 May '25

Dear all, due to the conference running late, the OWABI www.warwick.ac.uk/owabi<http://www.warwick.ac.uk/owabi> seminars will start today at 10.30am UK time instead of 10am, as previously announced. The talks will be 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: 10.30-11am 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: 11-11.30am 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

Seminario di Sam Power - Pavia, 3 giugno 2025 ore 15
by Carlo Orrieri 28 May '25

28 May '25

Martedì 3 giugno alle ore 15 presso il Dipartimento di Scienze Economiche e Aziendali (aula E, piano terra) dell'Università di Pavia, Sam Power (University of Bristol) terrà un seminario: titolo: Gradient Flow Methods for Statistical Computation - Trends and Trajectories abstract: When conducting statistical estimation and inference, it is relatively commonplace that the dominant computational burden takes the form of an optimisation task. This has long been recognised for tasks of parameter estimation, though there is an increasing recognition that other tasks of interest can be fruitfully interpreted as optimisation tasks over a space of probability measures, or even over some 'hybrid' space involving both parameters and measures. In this talk, I will survey some trends in this area, focusing on how this high-level perspective finds use in both analysis of popular existing algorithms and synthesis of novel algorithms. I will also highlight opportunities for future contributions in this fast-growing area. Tutti gli interessati sono invitati a partecipare. Un caro saluto Carlo Orrieri

Seminario di Giorgio Cipolloni alla Sapienza
by Faggionato, Alessandra 28 May '25

28 May '25

Buongiorno Martedi' 3 Giugno alle ore 14:00 in Sala di Consiglio Giorgio Cipolloni (University of Arizona) terra' il seguente seminario Title: Logarithmically correlated fields from non-Hermitian random matrices Abstract: We study the Brownian evolution of large non-Hermitian matrices and show that their log-determinant converges to a 2+1 dimensional Gaussian field in the Edwards-Wilkinson regularity class, i.e. logarithmically correlated for the parabolic distance. 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 a 2 dimensional log-correlated field. Our result, previously not known even in the Gaussian case, holds out of equilibrium for general matrices with i.i.d. entries. We also study the extremal values of these fields and demonstrate their logarithmic dependence on the matrix dimension.

Seminario Padova - Vanessa Jacquier
by Alberto Chiarini 27 May '25

27 May '25

Buongiorno a tutti, Vorremmo segnalarvi che venerdì prossimo (30 Maggio) alle ore 14:30 in aula 2AB30 (Torre Archimede, Università di Padova) ci sarà un seminario per il ciclo di seminari in Probabilità e Finanza di: Vanessa Jacquier (Università di Padova) Title: Discrete Nonlocal Isoperimetric Inequality and Analysis of the Long-Range Bi-Axial Ising Model Date: May 30, 2025, at 14:30, 2BC30 Abstract: We consider a generalization of the classical perimeter, referred to as the nonlocal bi-axial discrete perimeter, in which not only the external boundary of a polyomino contributes to the perimeter, but all its internal and external components. In particular, this nonlocal bi-axial perimeter is a fractional function that depends on the shape of the given geometrical figure and on a parameter λ>1, which accounts for the long-range effect. We tackle the nonlocal discrete isoperimetric problem analyzing and characterizing the minimizers within the class of polyominoes with a fixed area. The solution of this isoperimetric problem provides a rigorous foundation for studying the metastable behavior of the long-range bi-axial Ising model. Vi aspettiamo numerosi!

Seminario di Amichai Painsky presso l'università Bicocca, Mercoledì 4 giugno
by Mario Beraha 27 May '25

27 May '25

Buongiorno a tutti, Vi segnalo il seguente seminario in presenza presso l’università di Milano-Bicocca. 4 giugno 2025, ore 12:00, Aula Seminario 2104, Edificio U7, Via Bicocca degli Arcimboldi, 8, Milano. Speaker: Amichai Painsky, Tel Aviv University Title: Large Alphabet Inference Abstract: Consider a finite sample from an unknown distribution over a large alphabet. Making inference in a large alphabet regime is a fundamental problem in statistics and related fields, which entails several basic challenges. For example, how accurately can we infer the parameters of events that do not appear in the sample? What can we say about the most frequent events in the sample? The entire underlying distribution? In this talk we introduce a novel inference scheme that tackles these challenging problems. Our proposed framework applies selective inference, as we construct confidence intervals (CIs) for the desired set of parameters. Interestingly, we show that obtained CIs are dimension-free, as they do not grow with the alphabet size. Further, we show that our CIs are (almost) tight, in the sense that they cannot be further improved without violating the prescribed coverage rate.

Short courses in GSSI trimester
by Lu Xu 27 May '25

27 May '25

Dear colleagues and friends, we are glad to announce the forthcoming short courses and seminar in GSSI in June: June 3-5 (short cours) & June 6 (seminar): Prof. Gian Michele Graf (ETH Zurich) June 10-12: Prof. Lenya Ryzhik (Stanford) Please see at the end of the email for the detailed information. Registration is free through the web form: https://indico.gssi.it/event/745/. Other courses hosted by the trimester can be found here: https://trimester2025.math.gssi.it/all_courses/. We would be grateful if you could circulate the announcement among potentially interested students and researchers. For any information do not hesitate to contact us (patterns(a)gssi.it<mailto:patterns@gssi.it>). ———————————————— Venue: Main Lecture Hall, Gran Sasso Science Institute (Viale F. Crispi 7, L’Aquila) ———————————————— Matter and topology: an overview Gian Michele Graf (ETH Zurich) 3/6 (Tue) 14:15-15:45 5/6 (Thu) 14:15-15:45 6/6 (Fri) 09:00-10:45 Topological insulators are materials that are conducting at their edge, though not in the bulk. Their essential physical properties are encoded by an index. After reviewing the historical origins, and the Quantum Hall effect in particular, the appropriate indices will be discussed (Chern numbers, index of a pair of projections), as well as bulk-edge correspondence. Thereafter symmetry protected topological insulators will be addressed. The focus will be on symmetries like time-reversal and particle-hole conjugation and, correspondingly, on the Quantum Spin Hall effect and Majorana zero modes in superconductors, in physical dimensions d=2 and 1, respectively. More broadly, the Kitaev table describes the kind of indices that occur in relation to many more symmetries, in any dimension d, and its derivation will be treated. Special topics beyond the above framework, such as time-dependent systems (Floquet or quantum pumps) or classical systems (hydrodynamics) may occur too, as time permits. ———————————————— SMAQ Seminar: Adiabatic charge pumps and Galilei covariance Gian Michele Graf (ETH Zurich) 6/6 (Fri) 14:00-15:30 The Thouless theory of quantum pumps establishes quantized transport per cycle and determines the necessary conditions. When the description is shifted to a moving reference frame, as suggested by recent experiments on ultracold gases, transported and residing charges mix. That transformation is encoded in Galilean space and time, but underlying it is one of vector bundles that may be described in a number of ways, that may or may not rely on Bloch theory. In one of them, the transformation mixes strong and weak indices of a bundle on a 2-torus; in another one, a 3-torus is at center stage; in yet another one, and somewhat informal way, the transformation is related to a paradox that astonished seafarers of centuries past. Joint work with T. Esslinger and F. Santi. ———————————————— Branching Brownian motion and knowledge diffusion: from Fisher-KPP to MFG Lenya Ryzhik (Stanford) 10/6 (Tue) 16:15-17:45 11/6 (Wed) 10:45-12:15 & 16:15-17:45 12/6 (Thu) 16:15-17:45 We will first discuss the general connection, via the voting models, between the branching Brownian motion (BBM) and the Fisher-KPP and other semilinear parabolic equations. This connection, together with the long time asymptotics of the solutions, allows, in particular, to deduce some fine properties of BBM, such as the law of large numbers and fluctuations of the limiting process near the maximum of BBM. In the second half of the lectures, we will discuss some knowledge diffusion models that arise in macroeconomics and lead to mean-field game type of problems that are also related to non-local Fisher-KPP equations. ———————————————— With our best wishes, Lu Xu Assistant Professor (RTDb) Gran Sasso Science Institute

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.
