Si avvisa che in data 16-10-2015, alle ore 14:30 precise, presso l'Aula Seminari "F. Saleri" VI piano - Dipartimento di Matematica, Politecnico di Milano, nell'ambito delle iniziative MOX, si svolgerà il seguente seminario: Relatore: Bill Sudderth School of Statistics, University of Minnesota Titolo: How to Control a Process to a Goal Abstract: Suppose that you have a fortune of $10 and seek to reach $100 by placing bets at xed odds on repetitions of a given event such as the appearance of red (or black) on each spin of a roulette wheel. What is the best strategy for you to reach your goal? What strategy will get you there in the least expected time? What if you are competing with another player? I will discuss these and related problems in both discrete and continuous time. Tutti gli interessati sono invitati a partecipare.

Tutti noi, orgogliosi di essere stati suoi allievi, vi diamo questo annuncio con profondo dolore. L'ultimo saluto verrà dato presso le celle dell'ospedale di Borgo Roma (Verona) lunedì 12 ottobre dalle ore 13.30 alle ore 14.30.

Seminario ROSSELL

******************************************************************* STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO ******************************************************************* Veberdi 16 Ottobre 2015 alle ore 12:00, presso l’Aula Rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: David ROSSELL (University of Warwick) CONSISTENCY OF POSTERIOR MODEL PROBABILITIES IN HIGH-DIMENSIONAL MODEL SELECTION Abstract: In recent years there has been an increasing interest in developing Bayesian formulations that remain effective in high-dimensional and non-standard problems. We focus on high-dimensional model selection problems where the number of parameters may grow with the sample size, and review results characterizing the situations under which one can hope for the posterior probability assigned to the data-generating truth to eventually converge to 1 (often termed "strong consistency"). As it turns out, under certain regularity conditions for the canonical linear model such consistency can only be achieved if the prior formulation is based on so-called non-local priors. We will review the non-local prior framework and present some recent extensions for high-dimensional estimation. Our theoretical and empirical results show that inducing model selection parsimony via non-local priors allows working with simpler models and improving prediction accuracy simultaneously. Although for simplicity we shall focus on variable selection settings, time allowing we will touch upon extensions to more complex settings such as graphical models or mixture models. Tutti gli interessati sono invitati a partecipare. Il seminario e' organizzato dalla "de Castro" Statistics Initiative (http://www.carloalberto.org/stats) in collaborazione con il Collegio Carlo Alberto.

mini-corso Ruodu Wang in Bicocca
by runggal＠math.unipd.it 08 Oct '15

08 Oct '15

Nell'ambito del programma di internazionalizzazione del Dottorato in Statistica e Matematica per la Finanza della Bicocca, il prof. Ruodu Wang del Department of Statistics and Actuarial Science della University of Waterloo terrà nei giorni 9,10 e 11 novembre un mini-corso su Risk aggregation and Fréchet problems Fréchet problems refer to questions related to an aggregation (sum, typically) of several random variables, where the marginal distribution of each individual random variable is known and the joint distribution (copula) is unspecific. Unfortunately (in fact, fortunately), a large number of questions in this field are still mathematically open. In the modeling of risk aggregation, individual risks and their dependence structure are often modeled separately, leading to uncertainty arising at the level of a joint model. As the dependence structure is typically uncertain, the study on quantitative characteristics (e.g. risk measures) of risk aggregation under model uncertainty leads to a variety of Frèchet problems. This course covers various topics in this quickly expanding field. The content is mainly based on recent research of the instructor and his collaborators. Le lezioni si svolgeranno dalle ore 14.30 alle 17.30 presso la Sala del Consiglio al IV piano dell'edificio U7. La partecipazione è libera ma è necessario iscriversi mandando una email a drm2015(a)unimib.it.

A Bayesian approach" Abstract: Simple examples show that data can contradict prior beliefs; one can be "surprised". But theoretically one always expects to learn in a well-defined way and the class of information functionals for which this is true is known and includes Shannon information.
