SPASS Seminars: Sandra Cerrai and Gianmarco Bet
by Francesco Grotto 15 Jun '23

15 Jun '23

Dear Colleagues, We would like to invite you to the following SPASS seminars, jointly organized by UniPi, SNS, UniFi and UniSi: *The Smoluchowski-Kramers diffusion-approximation for a class of constrained stochastic wave equations* *Sandra Cerrai* (University of Maryland) *Metastability for the Potts model with Glauber dynamics* *Gianmarco Bet *(University of Florence) The seminars will take place on TUE, 20.6.2023, respectively at 14:00 CET and at 15:00 CET in Sala Seminari, Dipartimento di Matematica, Pisa 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 (Cerrai at 14:00): We investigate the well-posedness of a class of stochastic second-order in time-damped evolution equations in Hilbert spaces, subject to the constraint that the solution lies within the unitary sphere. Then, we focus on a specific example, the stochastic damped wave equation in a bounded domain of a d-dimensional Euclidean space, endowed with the Dirichlet boundary condition, with the added constraint that the L^2-norm of the solution is equal to one. We introduce a small mass mu>0 in front of the second-order derivative in time and examine the validity of a Smoluchowski-Kramers diffusion approximation. We demonstrate that, in the small mass limit, the solution converges to the solution of a stochastic parabolic equation subject to the same constraint. We further show that an extra noise-induced drift emerges, which in fact does not account for the Stratonovich-to-Itô correction term.* *Abstract (Bet 15:00): In this talk, I will describe some recent result on the low-temperature metastabile behavior of the ferromagnetic Potts model on a finite two-dimensional grid-graph Λ, evolving according to Glauber dynamics. More specifically, to each spin configuration is associated an energy that depends on local spin alignment, as well as on an external magnetic field that acts only on one spin value. We describe separately the case of negative, positive and, if time allows, zero external magnetic field. In the first case there are q − 1 stable configurations and a unique metastable state. In the second case there are q − 1 symmetric metastable configurations and only one global minimum. In the third scenario the system has q stable equilibria. In the negative and positive cases we study the asymptotic behavior of the first hitting time from the metastable to the stable state as the inverse temperature tends to infinity. Moreover, in both cases we identify the union of gates and prove that this union has to be crossed with high probability during the transition. Based on joint work with Anna Gallo and Francesca Nardi. *

One World ABC: J. Arruda and Y. Shälte- June 29, 9.30am UK time
by Massimiliano Tamborrino 15 Jun '23

15 Jun '23

Dear all, the last One World ABC Seminar<https://www.warwick.ac.uk/oneworldabc> of the season is quickly approaching! On Thursday, June 29, at 9.30am UK time, Jonas Arruda and Yannik Shälte (University of Bonn) will talk about "Amortized simulation-based inference for non-linear mixed-effects models" with an reported below. Abstract: Non-linear mixed-effects models are a powerful tool for studying heterogeneous populations in biology, medicine, engineering, and other fields. However, fitting these models is computationally challenging when the description of individuals is complex and the population is large. To address this issue, we propose the use of neural density estimation to approximate entity-specific posterior distributions in an amortized fashion. This approximation is then used to efficiently infer population-level parameters. Applying this approach to problems from single-cell biology, we demonstrate its scalability to large datasets in an unprecedented manner. Moreover, it enables accurate uncertainty quantification, simple testing of hypotheses, and extends to stochastic models, going beyond what established methods can give. In summary, our method constitutes a highly flexible novel approach has the potential to substantially improve the analysis of heterogeneous populations. The talk will be hosted on MS Teams here: https://teams.microsoft.com/l/meetup-join/19%3ameeting_OTYyY2FkMWQtZTkwNi00… We are looking forward to seeing you soon, best, Massimiliano on the behalf of the One World ABC Seminar Organisers ------ Dr. Massimiliano Tamborrino Associate Professor Department of Statistics University of Warwick https://warwick.ac.uk/tamborrino

seminario di Gianni Pistone (DISMA-Politecnico di Torino)
by Paola Siri 14 Jun '23

14 Jun '23

Martedì 20 Giugno alle ore 11.00 presso l’aula seminari del DISMA (Politecnico di Torino) il prof. GIOVANNI PISTONE (de Castro Statistics, Collegio Carlo Alberto, e DISMA (former faculty)) terrà un seminario dal titolo Information Geometry of ANOVA and Transport Theory. ABSTRACT. Functional ANOVA (ANalysis Of VAriance) is used in Statistics and Sistem Theory. It is a non-parametric orthogonal splitting of the vector space of $L^2$ random variables. We use it to split the fibres of the affine statistical bundle. The base set consists of probability densities, and the fibres are vector spaces of Fisher’s scores. On a product sample space, one of the factors in the splitting is an additive model, while the other is a transport model. Tutti gli interessati sono invitati a partecipare. Per chi non avesse possibilità di partecipare in presenza, l'evento sarà trasmesso in streaming al seguente link https://didattica.polito.it/VClass/SeminarioPistone Paola Siri e Barbara Trivellato Paola Siri Probability, Statistics and Optimization group Department of Mathematical Sciences "G. L Lagrange" Politecnico di Torino [cid:A8CB887B-8B14-40BE-AAAD-8875D1B7658A]

oggi ore 11.00 - Seminario Prof.ssa E. Rroji
by Enea Bongiorno 14 Jun '23

14 Jun '23

Buongiorno, con piacere segnalo il seguente seminario che si terrà oggi: -------------------------------- 14 giugno ore 11.00 - aula 101, campus Perrone, via Perrone, 18, Novara. Università del Piemonte Orientale. - on-line: meet.google.com/yvq-ccbt-pzt Title:* On the microstructure of green bonds* *Prof. Edit Rroji* University of Milano Bicocca - DISMEQ Abstract: The idea of this paper is to investigate differences in brown and green bonds from the lens of the trading activity. Our research exploits the idea that positive and negative jumps in the dynamics of returns have a specific memory nature that can be modelled through a self-exciting process. We investigate the microscopic structure and properties of high-frequency series of green and brown bonds using Hawkes type processes where the kernel is a CARMA(p,q) model. Empirical results suggest that the bid-ask spread of green bonds on average is larger for bonds issued by a financial institution while the opposite happens for bonds issued by a non financial company. Moreover, we observe that the intensities respectively of positive and negative jumps in the price dynamics are not stationary through time. Higher order bivariate Hawkes models provide better fitting results in our datasets, especially for the issuer that operates in the energy sector. This presentation is based on a joint work with Lorenzo Mercuri (University of Milan) and Andrea Perchiazzo (Vrije Universiteit Brussel). ----------------------------------- Locandina dell'evento <https://drive.google.com/file/d/1NunY3uhobfzBtP0qUUbxLJpnqcvFn4JM/view?usp=…> Seminari Matematici Statistici <https://sites.google.com/uniupo.it/seminari-ms/home-page> ----------------------------------- Tutti gli interessati sono invitati a partecipare.
