PEANO" UNIVERSITA' DEGLI STUDI DI TORINO ********************************************************************* Venerdì 4 Marzo 2016 alle ore 15:00 in Aula C presso il Dipartimento di Matematica "G. Peano" dell'Università degli Studi di Torino, Via Carlo Alberto 10, La Dott.ssa MARTA PITTAVINO (University of Zurich) terrà un seminario dal titolo "Modelling multivariate data with additive Bayesian networks" Abstract: Bayesian networks are a form of graphical model which derives from empirical data a directed acyclic graph describing the dependency structure between random variables. Especially, additive Bayesian networks (ABNs) extend the usual generalized linear models to multiple dependent variables without involving dimension reduction. Existing software for working with ABNs are useful for dealing with these models for heterogeneous applications in systems epidemiology and biology. However, limitations in terms of computation and feasibility can be still open challenges. In this talk, an introduction to ABN model will be provided, together with a description of the R package abn, whereby applications of these models to systems epidemiology and biology are showed. Moreover, a theoretical development will be presented as an initial step to overcome open questions. Specifically, the result of fitting an ABN to a data set is translated into optimizing the likelihood of observing the data under the studied model: the marginal likelihood (ABN network score). A novel conjugate prior distribution for ABNs models is introduced that helps us to address the goodness of fit computation and the posterior parameter estimation. Tutti gli interessati sono invitati a partecipare. -- Federico Polito Department of Mathematics University of Torino Via Carlo Alberto, 10 10123, Torino, Italy Email: federico.polito(a)unito.it Tel: +39 011 6702937 Web: www.federicopolito.it

TIME-VARYING SIS PREVALENCE IN NETWORKS: THEORY AND A NEW APPROXIMATE FORMULA 25 febbraio 2016 *Luogo:* Dipartimento di Matematica, via Sommarive, 14 - Povo (TN) - Aula Seminari *Ore* 10:00 *Relatore:* - *Piet Van Mieghem** (*TU Delft Olanda*)* *Abstract: * Currently, epidemic spreading processes on networks are popular to model diffusion phenomena in real-world networks. After reviewing some basics about the continuous-time SIS Markov process on networks, we will focus on the prevalence, the average fraction of infected nodes in the network. Based on a recent exact differential equation containing the Laplacian matrix of the underlying graph, the time dependence of the SIS prevalence is first studied and then upper and lower bounded by a new, explicit analytic function of time. Our new approximate formula obeys a Riccati differential equation and bears resemblence to the classical expression in epidemiology of Kermack and McKendrick (1927), but enhanced with graph specific properties, such as the algebraic connectivity, the second smallest eigenvalue of the Laplacian of the graph. A comparison with the N-Interwined Mean-Field Approximation (NIMFA) and simulations of the exact continuous-time Markovian SIS process on a graph exhibit the accuracy and the potential of the new analytic formula. *Referente: *Stefano Bonaccorsi

The collection of these single spread events can be defined as the 'spread' or 'martensite spread'. First, in this paper, martensite spreads are analyzed to estimate the mean number of partially transformed grains in a single spread event. Secondly, taking the quantitative knowledge gained from this analysis as a starting point, a computer simulation of the martensite spread is proposed. This computer simulation is carried out in a 3-d network of space-filling grains represented as Kelvin polyhedra and is based on a probabilistic approach. The experimental and simulation results are presented, compared and discussed. We conclude that the probabilistic computer simulation of martensite spread could successfully describe important quantitative aspects of martensite spread Tutti gli interessati sono invitati a partecipare.

Sorry, the previous announcement had a wrong date Tuesday, February 9, 2016 from 12:00 to 13:00 LUISS room 207 Viale Romania 32 00197 Roma Speaker Roberto Cominetti (Universidad Adolfo Ibañez) Title "Risk measures and shortest paths in network games" ABSTRACT: We consider network congestion games with risk-averse players. We review some recent proposals for computing risk-sensitive optimal paths, starting from the simplest Markowitz approach based on mean-stdev optimization. This approach presents some significant drawbacks in terms of its computational complexity, lack of monotonicity, as well as a dynamic inconsistency phenomenon which arises when one re-evaluates an optimal path along the way. This inconsistency also affects other popular measures of risk such as VaR, CVaR, and semi-deviations. As a matter of fact, under minimal conditions, we show that the only risk measures that are dynamically consistent are the so-called "entropic risk measures". With these measures, and assuming that link travel times are independent, a risk-sensitive optimal path reduces to a standard shortest path problem which can be solved efficiently. This extends directly to equilibrium situations where the network is used concurrently by many players. However, link travel time correlations are to be expected in game situations, which gives rise to a number of issues and questions that will be pointed out during the talk. This talk is based on joint work with Alfredo Torrico.

Seminario Andrea Cosso a Milano-Bicocca
by federica.masiero＠unimib.it 02 Feb '16

02 Feb '16

Il giorno 10 Febbraio, alle ore 10.30, presso il Dipartimento di Matematica e Applicazioni dell'Università di Milano-Bicocca, via Cozzi, 55, Edificio U5, aula 2109 (secondo piano), il Dott. Andrea Cosso, Politecnico di Milano, terrà un seminario dal titolo "Randomization method and backward SDEs for optimal control of partially observed path-dependent stochastic systems" Abstract: In the present talk we introduce a general methodology, which we refer to as the randomization method, firstly developed for classical Markovian control problem in the paper: I. Kharroubi and H. Pham "Feynman-Kac representation for Hamilton-Jacobi-Bellman IPDE", Ann. Probab., 2015. As it is well-known, the dynamic programming method is the standard methodology implemented for the study of classical Markovian control problems, which allows to relate the value function to the Hamilton-Jacobi-Bellman equation through the so-called dynamic programming principle. The key feature of the dynamic programming method is that the knowledge of the value function allows, at least in principle, to find an optimal control for the problem. This very powerful and well-known methodology breaks down (in the sense that it can not be directly implemented in a standard way) when we face control problems which present the following additional features: partial observation, path-dependence, delay in the control. On the other hand, the randomization method can be quite easily generalized and adapted to these more general control problems. The aim of the talk is to illustrate this latter point, starting with the presentation of the fundamental ideas of the randomization method. The talk is based on a joint work in progress with E. Bandini, M. Fuhrman, H. Pham. Tutti gli interessati sono invitati a partecipare. Cordiali saluti, Federica Masiero

Tristissima notizia
by Nappo, Giovanna 31 Jan '16

31 Jan '16

Con profondo cordoglio vi annuncio la scomparsa di Enza Orlandi. Enza Orlandi ha lavorato presso il Dipartimento di Matematica dell'Università di Roma, La Sapienza, dal 1981 al 1992, successivamente all'Università dell'Aquila fino al 1995, ed infine all'Università di Roma Tre, sempre apprezzata per il suo rigore e il suo impegno. La sua attività scientifica si concentrata principalmente sugli aspetti probabilistici della Fisica Matematica. I suoi numerosi lavori sono apprezzati a livello internazionale, e ha avuto collaborazioni scientifiche di altissimo livello. Recentemente il suo impegno era stato riconosciuto in modo ufficiale anche in Italia: era infatti risultata idonea sia come Professore Ordinario di Probabilità che di Fisica Matematica. Martedì 2 Febbraio dalle 10.00 alle 10.30 si terra’ una cerimonia informale presso il Tempietto Egizio, Cimitero del Verano, Roma, per darle un ultimo saluto. Giovanna Nappo
