Seminario di Probabilità - Università di Padova
by alessandra bianchi 17 Jan '14

17 Jan '14

Ho il piacere di invitarvi al seguente seminario che si terrà venerdì 31 gennaio, alle ore 14:30, nell'aula 2AB45 della Torre Archimede presso il Dipartimento di Matematica dell'Università degli Studi di Padova. Speaker: Dott. Tal Orenshtein Affiliation: Department of Mathematics, University of Munich Title: Excitements in one dimension Abstract: Excited random walk (also called Cookie walk) is a self interacting discrete time stochastic process on graphs so that the transition probability is given not only by the location, but also by the number of past visits to that location. We shall discuss some old and new results on the one-dimensional lattice case, which has a special structure. Joint with Gideon Amir and Noam Berger. -- Alessandra Bianchi Dip. di Matematica Pura e Applicata Università di Padova Via Trieste, 63 - 35121 Padova, Italy phone: +39 049 827 14 06 fax: +39 049 827 14 28 e-mail: bianchi(a)math.unipd.it http://www.math.unipd.it/~bianchi/

seminario del Prof. Ivan Gentil a Pavia - messaggio corretto
by Carbone Raffaella 17 Jan '14

17 Jan '14

Cari colleghi, il giorno martedì 21 gennaio 2014, alle ore 15, presso la sala conferenze dell'IMATI-CNR di Pavia, il Prof. Ivan Gentil (University of Lyon 1) terrà il seminario dal titolo *Contraction in Wasserstein distance for Markov diffusion semigroups * nell'ambito del Seminario di Matematica Applicata (IMATI-CNR e Dipartimento di Matematica, Pavia). Abstract : Under curvature condition the Wasserstein distance has some contraction properties between two solutions of the heat equation (on a manifold for instance). We investigate how the dimension appears in the contraction inequality.

----------------------------------------------------------------------------- A v v i s o d i S e m i n a r i o ----------------------------------------------------------------------------- Venerdì 17 Gennaio, ore 11am ----------------------------------------------------------------------------- Stanza 34 Dipartimento di Scienze Statistiche Sapienza Università di Roma ALESSIO FARCOMENI (Dip. Sanità Pubblica e Malattie Infettive, Sapienza Università di Roma) terrà un seminario dal titolo GENERALIZED LINEAR MIXED MODELS BASED ON LATENT MARKOV HETEROGENEITY STRUCTURES tutti gli interessati sono invitati a partecipare. ----------------------------------------------------------------------------- Maggiori informazioni sui seminari presso il DSS sono consultabili a quest'indirizzo: http://goo.gl/Y6OQYm Saluti Pierpaolo Brutti - Fulvio De Santis --- Summary Latent Markov models (LM) can be seen as a flexible device for taking into account time-varying subject-specific unobserved heterogeneity. In the basic LM, a random intercept is flexibly allowed to evolve over time. The available formulations of mixed LM often assume that any additional random effect is time-constant, with few specific exceptions. In this work we formulate a mixed latent Markov model in which all random effects may freely evolve over time. The size of the parameter space is controlled with the possibilities of assuming block independence of random effects, and/or that groups of random effects may share some or all aspects of their distribution. Parameter estimation is carried out with a simple expectation maximization strategy, analogous to that used for the basic latent Markov model, after an adaptation of the usual forward backward recursions and a parsimonious representation of the expected complete likelihood. Standard errors are derived using Oakes' identity. Dependence among random effects is summarized using Watanabe's total correlation and described with log-odds ratios and higher-order log-linear interactions. We illustrate with an original application to the relationship between health literacy and depression in a panel of adolescents. In this example subjects are clustered in schools, which leads to high-dimensional multivariate time-varying random effects.

The geometric invariants are the fixed length of a random chain and the constant radius of a sphere, which is the surface for random walks (for example, in the case of a turning diffusion). The integral invariants are represented as integrals of kernel functions of integral invariants on the whole space. These kernel functions are solutions of SDEs, which were obtained and discussed. Furthermore, kernel functions will be used for deriving the first global stochastic integral, for constructing the program control (with probability one) for stochastic dynamical systems on deterministic manifold based on Brownian motion with Poisson jumps, and for obtaining the Kolmogorov equations.
