Seminar in Pisa: Giulia Carigi
by Francesco Grotto 29 Mar '22

29 Mar '22

Dear Colleagues, we would like to invite you to the following seminar by Giulia Carigi (University of Reading) to be held next Wednesday (March 30th) at Dipartimento di Matematica in Pisa and online via Google Meets. The organizers, A. Agazzi and F. Grotto -------------------------------------------- Location: Sala Seminari, Dipartimento di Matematica, Pisa Google Meet Link: https://meet.google.com/gji-phwo-vbg Time: March 30, 2022, 14:00 CET Speaker: Giulia Carigi (University of Reading) Title: Ergodic properties for a stochastic two-layer model of geophysical fluid dynamics Abstract: A two-layer quasi-geostrophic model for geophysical flows is studied, with the upper layer being perturbed by additive noise. This model is popular in the geosciences, for instance to study the effects of a stochastic wind forcing on the ocean. A rigorous mathematical analysis however meets with the challenge that the noise configuration is spatially degenerate as the stochastic forcing acts only on the top layer. Exponential convergence of solutions laws is established, implying a spectral gap of the associated Markov semigroup on a space of Hölder continuous functions. Moreover, response theory with respect to changes in the average wind forcing is established. Specifically, it is shown that the averages of a class of observables against the invariant measure are differentiable (linear response) and locally Hölder continuous (fractional response) as functions of a deterministic additive forcing. In doing so, a framework suitable to establish (linear and fractional) response for a class of nonlinear stochastic partial differential equations is provided.

28 Mar '22

Cari colleghi scusandomi per eventuali messaggi multipli, vi mando le informazioni sui prossimi seminari online del Gruppo UMI Prisma (lunedì 4 aprile), con i contributi di Enrico Scalas e Giacomo Ascione: * April 4, 2022, 16:00-17:00 (CET): Enrico Scalas TITLE: Point processes and time change: A fractional non-homogeneous Poisson process and its functional limits ABSTRACT: A fractional nonhomogeneous Poisson process was introduced by a time change of the nonhomogeneous Poisson process with the inverse α-stable subordinator. A similar definition is proposed for the (nonhomogeneous) fractional compound Poisson process. Both finite-dimensional and functional limit theorems are presented for the fractional nonhomogeneous Poisson process and the fractional compound Poisson process. The results are derived by using martingale methods, regular variation properties and Anscombe’s theorem. Some of the limiting results are verified in a Monte Carlo simulation. Papers: [1] Nikolai Leonenko, Enrico Scalas and Mailan Trinh, The fractional non-homogeneous Poisson process. Statistics and Probability Letters, 120, 2017, pp. 147-156. DOI: http://dx.doi.org/10.1016/j.spl.2016.09.024 https://arxiv.org/abs/1601.03965 [2] Nikolai Leonenko, Enrico Scalas and Mailan Trinh, Limit theorems for the fractional nonhomogeneous Poisson process, Journal of Applied Probability , 56:1, 2019 , pp. 246 - 264. DOI: https://doi.org/10.1017/jpr.2019.16 https://arxiv.org/abs/1711.08768 This is joint work with Nikolai Leonenko and Mailan Trinh. * April 4, 2022, 17:00-18:00 (CET): Giacomo Ascione TITLE: Spectral methods for time-changed birth-death processes ABSTRACT: In this talk we focus on a class of semi-Markov birth-death processes obtained by means of a time-change of some standard birth-death process. Precisely, we consider as parent processes the immigration-death process and the Meixner process, whose stationary distributions are respectively the Poisson and the Pascal distributions. Exploiting, on one hand, the properties of the Charlier and Meixner polynomials (in particular, the self-duality property), while, on the other, characterizing the eigenfunctions of some non-local operators by means of the Laplace transform of an inverse subordinator, we are able to explicitly express the spectral decomposition of the transition probability function of the aforementioned processes. The latter expression is then used to prove existence and uniqueness of strong solutions for a class of time-nonlocal Cauchy problems in a suitable Banach sequence space and the probabilistic interpretation of such equations as some sort of non-local backward/forward Kolmogorov equations. Finally, a comparison with the time-changed diffusion case is carried out by referring to the spectral decomposition of the probability density function of time-changed Pearson diffusions. The latter argument hints at the possibility of applying this kind of spectral methods to a wider range of problems. This is the result of joint work with Nikolai Leonenko from Cardiff University and Enrica Pirozzi from University of Naples.

SEMINARS IN STATISTICS @ COLLEGIO CARLO ALBERTO <https://www.carloalberto.org/events/category/seminars/seminars-in-statistic…> Venerdi 1 Aprile 2022, alle ore 12.00, presso il Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Speaker: *Alexandra Carpentier* (University of Potsdam) Title: *Optimal ranking in crowd-sourcing* Abstract: Consider a crowd sourcing problem where we have n experts and d tasks. The average ability of each expert for each task is stored in an unknown matrix M, which is only observed in noise and incompletely. We make no (semi) parametric assumptions, but assume that both experts and tasks can be perfectly ranked: so that if an expert is better than another, she performs on average better on all tasks than the other - and that the same holds for the tasks. This implies that if the matrix M is permuted so that the experts and tasks are perfectly ranked, then the permuted matrix M is bi-isotonic. We focus on the problem of recovering the optimal ranking of the experts in l_2 norm, when the questions are perfectly ranked. We provide a minimax-optimal and computationally feasible method for this problem, based on hierarchical clustering, PCA, and exchange of informations among the clusters. We prove in particular - in the case where d > n - that the problem of estimating the expert ranking is significantly easier than the problem of estimating the matrix M. This talk is based on joint work with Emmanuel Pilliat and Nicolas Verzelen. ------------------------------------------------ In ottemperanza alle norme anti Covid, per partecipare in presenza è necessario prenotarsi tramite il seguente form online: https://forms.gle/Z3MVuM7MixQHxrmF6 Sarà possibile seguire il seminario anche in streaming: Join Zoom Meeting <https://us02web.zoom.us/j/81557586058?pwd=SllnbU8wcDh4M2pFNEEvQkk5Q2VqUT09> Meeting ID: 815 5758 6058 Passcode: 518172 Il seminario è organizzato dalla "de Castro" Statistics Initiative www.carloalberto.org/stats Cordiali saluti, Pierpaolo De Blasi -- Pierpaolo De Blasi University of Torino & Collegio Carlo Alberto carloalberto.org/pdeblasi <https://sites.google.com/a/carloalberto.org/pdeblasi/>

The method is based on the idea of deriving an approximate posterior density aiming to target the true (unavailable) posterior by running massive simulations from the model for different parameters to replace the intractable likelihood, choosing then those parameters whose simulations are good matches to the observed data. When applying ABC to stochastic models, the derivation of effective summary statistics and proper distances is particularly challenging, since simulations from the model under the same parameter configuration result in different output. Moreover, since exact simulation from complex stochastic models is rarely possible, reliable numerical methods need to be applied. In this talk, we show how to use the underlying structural properties of the model to construct specific ABC summaries that are less sensitive to the intrinsic stochasticity of the model, and the importance of adopting reliable property-preserving numerical (splitting) schemes for the synthetic data generation. Indeed, the commonly used Euler-Maruyama scheme may drastically fail even with very small stepsizes. The proposed approach is illustrated first on the stochastic FitzHugh-Nagumo model, and then on the broad class of partially observed Hamiltonian stochastic differential equations, in particular on the stochastic Jensen-and-Rit neural mass model, both with simulated and with real electroencephalography (EEG) data, for both one neural population [2] and a network of neural populations (ongoing work).

(PMS)^2 online talk: Luisa Andreis
by margherita Zanella 22 Mar '22

22 Mar '22

Dear colleagues, we are happy to announce the following online talk: Speaker: Luisa Andreis (Università di Firenze) Title: Phase transitions in random graphs and coagulation processes. Abstract: Inhomogeneous random graphs are a natural generalization of the well-known Erdos–Renyi random graph, where vertices are characterized by a typeand edges are present independently according to the type of the vertices thatthey are connecting. In the sparse regime, these graphs undergo a phase transition in terms of the emergence of a giant component exactly as the classical Erdos–Renyi model. We will present an alternative approach, via large deviations, to prove this phase transition. This allows a comparison with the gelationphase transition in coagulation processes and with phase transitions of condensation type emerging in several systems of interacting components. This is based on ongoing joint works with Wolfgang K\"onig (WIAS and TUBerlin), Tejas Iyer (WIAS), Heide Langhammer (WIAS), Elena Magnanini(WIAS) and Robert Patterson (WIAS).

Peano" dell'Università degli Studi di Torino, Via Carlo Alberto 10, il Prof. *Giacomo Aletti* (Dipartimento di Scienze e Politiche Ambientali, Università degli studi di Milano) terrà un seminario dal titolo *Mathematical, numerical and statistical problems in the analysis of probabilistic counting of distinct elements* Abstract: Data streams are sequences of objects that cannot be available for random access but must be analyzed sequentially when they arrive and immediately discharged. One of the main applications in streaming algorithms concerns the problem of counting the number F0 of distinct elements in a stream, when the information that can be stored is of the order of the logarithm of the quantity of interest F0. In this seminar, the Flajolet-Martin class of probabilistic algorithms is analyzed from a probabilistic point of view, thus opening several computational, statistical, and mathematical problems. Connections with some consolidated theories will be shown. The results presented may be found in Aletti G. Analytical Confidence Intervals for the Number of Different Objects in Data Streams.

E' possibile seguire il seminario on line su piattaforma WebEx. *Chi fosse interessato, può mandarmi una email e provvederò a inviare l'invito (con il link)* Cordiali saluti -- %------------------------------------------------------- Elvira Di Nardo Dept.

Seminar in Pisa: Langxuan Su
by Francesco Grotto 16 Mar '22

16 Mar '22

Dear Colleagues, we would like to invite you to the following seminar by Langxuan Su (Duke University) to be held next Wednesday in Pisa and online via Google Meets. The organizers, A. Agazzi and F. Grotto ------------------------------------------------------- Location: Sala Seminari, Dipartimento di Matematica, Pisa Google Meet Link: https://meet.google.com/gji-phwo-vbg Time: March 23, 2022, 15:00 CET Speaker: Langxuan Su (Duke University) Title: A Large Deviation Approach to Posterior Consistency in Dynamical Systems Abstract: We provide asymptotic results concerning (generalized) Bayesian inference for certain dynamical systems based on a large deviation approach. Given a sequence of observations, a class of parametrized model processes and a loss function, we specify the generalized posterior distribution. We state conditions on the model family and the loss function such that the posterior distribution converges. The two conditions we require are: (1) a conditional large deviation behavior for a single model process, and (2) an exponential continuity condition over the model family for the map from the parameter to the loss incurred between a model process and the observations. The proposed framework is quite general, we apply it to two very different classes of dynamical systems: continuous time hypermixing processes and Gibbs processes on shifts of finite type. We also show that the generalized posterior distribution concentrates asymptotically on those parameters that minimize the expected loss and a divergence term, hence proving posterior consistency.
