********************************************************************* M.Sc. in STOCHASTICS and DATA SCIENCE http://www.master-sds.unito.it/do/home.pl UNIVERSITA' DEGLI STUDI DI TORINO ********************************************************************* Martedì 9 Maggio 2017 alle ore 11:30 in Aula 12 (Corso Unione Sovietica 218/bis, School of Management and Economics), nell'ambito delle attività previste per il corso di Statistics for Stocahstic Processes il Prof. Christophe Ley (Ghent University, Belgio) terrà un seminario dal titolo An alternative ranking for national soccer teams based on strength parameters Abstract: The FIFA ranking of national (male) soccer teams suffers from various drawbacks that cause heated debates, all-the-more as this ranking governs the seating in the international tournaments and the associated qualification rounds. In the present paper, we propose five alternative models based on strength parameters that are determined by maximum likelihood estimation. We conduct a comparison of these five statistical models, to which we add the ELO model used for the women's FIFA ranking, on grounds of their predictive performance. Indeed, contrary to regular league rankings, the FIFA ranking is designed to measure the current strength of teams, hence should allow accurate predictions of future matches. Our comparison is based on fifteen English Premier League seasons. The best performing model is then used to build the alternative FIFA ranking. We furthermore show its predictive power by analyzing the 2016 European Championship and comparing our predictions to the bookmaker ratings, usually considered as golden standard. Tutti gli interessati sono invitati a partecipare. -- %------------------------------------------------------- Elvira Di Nardo Dept. Mathematics "G.

Annuncio Seminario di Probabilita, Pisa, Martedi' 2 maggio

Annuncio Seminario di Probabilita, Pisa, Universita' di Pisa Martedi' 2 maggio, ore 11:00, Aula Seminari Seminario di Probabilita’ SPEAKER: Konstantin Matetski (University of Toronto) TITLE: Convergence of general weakly asymmetric exclusion processes ABSTRACT: In my ongoing work with J. Quastel we consider spatially periodic growth models built from weakly asymmetric exclusion processes with finite jump ranges and general jump rates. We prove that at a large scale and after renormalization these processes converge to the Hopf-Cole solution of the KPZ equation driven by Gaussian space-time white noise. In contrast to the celebrated result by L. Bertini and G. Giacomin (in the case of the nearest neighbour interaction) and its extension by A. Dembo and L.-C. Tsai (for jumps of sizes at most three) we don’t use the Hopf-Cole transform and work with the KPZ equation using regularity structures. The price which we have to pay for this approach is a non-trivial renormalization which has not been observed before for equations with stationary noises. In my talk i will give a general review of the Hopf-Cole solution to the KPZ equation and the results of the aforementioned authors. After that I will introduce a general weakly asymmetric exclusion process and explain the difficulty with renormalization. Tutti gli interessati sono invitati a partecipare.

Seminario di F. den Hollander a Milano-Bicocca (10.05.2017)
by Francesco Caravenna 27 Apr '17

27 Apr '17

Mercoledì 10 maggio 2017 alle ore 14:30, nell'ambito del Seminario Matematico e Fisico di Milano, Frank den Hollander (Leiden University) terrà un seminario dal titolo "Random walks on dynamic random graphs" Aula 3014, Dipartimento di Matematica e Applicazioni (edificio U5, via Cozzi 55, Milano) Università di Milano-Bicocca Trovate il sommario di seguito. Tutti gli interessati sono invitati a partecipare. Francesco Caravenna %%%%%%%%%%%%%%%%%%%%%%%% The mixing time of a random walk is the time it needs to approach its stationary distribution. For random walks on graphs, the characterisation of the mixing time has been the subject of intensive study. One of the motivations is the fact that the mixing time gives information about the geometry of the graph. In the last few years, much attention has been devoted to the analysis of mixing times for random walks on \emph{random graphs}, which poses interesting challenges. Many real-world networks are dynamic in nature. It is therefore natural to study random walks on \emph{dynamic random graphs}. In this talk we consider a random walk on the configuration model, i.e., a random graph with prescribed degrees. We investigate what happens when at each unit of time a fraction $\alpha_n$ of the edges is randomly relocated, where $n$ is the number of nodes. We identify \emph{three regimes} for the mixing time in the limit as $n \to \infty$, depending on the choice of $\alpha_n$. These regimes exhibit surprising behaviour. Joint work with Luca Avena (Leiden), Hakan Guldas (Leiden) and Remco van der Hofstad (Eindhoven) %%%%%%%%%%%%%%%%%%%%%%%% _________________________________________ Francesco Caravenna Dipartimento di Matematica e Applicazioni Università degli Studi di Milano-Bicocca Via Cozzi 55, 20125 Milano, Italy http://www.matapp.unimib.it/~fcaraven/ _________________________________________

Seminario di probabilità e statistica matematica Martedì 2 maggio, ore 14 Aula di Consiglio, Dipartimento di Matematica Guido Castelnuovo Cristina Costantini, Università D'Annunzio Chieti-Pescara LA DIFFUSIONE DI POISSON-DIRICHLET A DUE PARAMETRI COME LIMITE DI MODELLI DI GENETICA Riassunto: Oltre alle ben note applicazioni in statistica Bayesiana, teoria dei numeri, ecc., la distribuzione di Poisson-Dirichlet ha un’importante signiﬁcato in genetica: infatti e’ l’unica distribuzione stazionaria della diﬀusione che descrive il comportamento delle frequenze, ordinate in ordine decrescente, degli alleli presenti in una popolazione, al tendere all’inﬁnito della dimensione della popolazione e del numero di alleli. La distribuzione di Poisson-Dirichlet a due parametri e’ una generalizzazione della distribuzione di Poisson-Dirichlet che emerge in particolare nello studio delle escursioni del moto Browniano e nella teoria del rinnovo. Nel 2009 Petrov ha costruito una diﬀusione che ammette la distribuzione di Poisson-Dirichlet a due parametri come unica distribuzione stazionaria. Fino a oggi pero’ non era stato possibile collegare questa diﬀusione a modelli di genetica. Nel seminario esporro’ un recente risultato, ottenuto in collaborazione con P. De Blasi, S. Ethier, M. Ruggiero, D. Spano`, che dimostra che la diﬀusione costruita da Petrov e’ il limite, al tendere all’inﬁnito della dimensione della popolazione e del numero di alleli, di modelli di genetica che descrivono l’evoluzione delle frequenze, ordinate in ordine decrescente, degli alleli nella popolazione, in presenza non solo di mutazioni, ma anche di immigrazione da un’altra popolazione. Tutti gli interessati sono invitati a partecipare. Per informazioni rivolgersi a piccioni(a)mat.uniroma1.it
