Avviso di seminario :: Causeur@DSS (Scienze Statistiche, Sapienza)

----------------------------------------------------------------------------- A v v i s o d i S e m i n a r i o ----------------------------------------------------------------------------- Mercoledì 05 Dicembre, ore 11:00am ----------------------------------------------------------------------------- Sala 34 (quarto piano) Dipartimento di Scienze Statistiche Sapienza Università di Roma DAVID CAUSEUR (Agrocampus Ouest, Dep. of Statistics and Computer Science) terrà un seminario dal titolo HANDLING DEPENDENCE OR NOT IN STATISTICAL LEARNING FOR HIGH-DIMENSIONAL DATA tutti gli interessati sono invitati a partecipare. ----------------------------------------------------------------------------- Saluti Pierpaolo Brutti --- ABSTRACT The proper way to handle dependence across features in high-throughput data has raised fundamental discussions with unclear general conclusions or final recommendations. One of the most obvious illustration of this point is the tremendous effort of the statistics research community to address the impact of dependence on the False Discovery Rate (FDR)-controlling method by Benjamini and Hochberg (1995), which was initially designed under an independence assumption. Another famous questioning example is provided by the strikingly good performance of a naïve Bayes procedure ignoring dependence in a comparative study of machine learning methods by Dudoit et al. (2002) to predict classes from gene expression data. Addressing the dependence issue has often consisted in assessing its detrimental impact on the performance of standard methods designed to be optimal under independence, and deduce patches. To be valid for arbitrarily complex dependence patterns, such approaches in which dependence is viewed as a curse can lead to poorly powerful procedures. Therefore, both for machine learning and testing issues, a new generation of methods have emerged, advocating for an ad-hoc handling of dependence consisting in a preliminary whitening of the data (see Ahdesmäki and Strimmer, 2010, Hall and Jin, 2010). However, disentangling the dependent noise and the true association signal is very challenging and decorrelation can then lead to an alteration of the true association signal. For the purpose of global testing, where the objective is to test for the significance of an association signal between a set of features and a covariate, Arias-Castro el al. (2011) suggests that the optimal handling of dependence shall be specific of the pattern of the true association signal, especially through its sparsity rate. The former global testing framework covers a wide scope of applications, such as functional Analysis of Variance (fANOVA) and association tests between a region of the genome formed by contiguous Single Nucleotide Polymorphisms (SNP) and a case/control response variable in Genome Wide Association Studies. Interestingly, in the two former fields of applications, many popular methods are just based on simple aggregation of pointwise test statistics ignoring their dependence. The talk will start by a selection of short stories with confusing conclusions about the proper way to handle dependence. After a tentative clarification, I will introduce two methods for global testing in which whitening is adapted both to the pattern of dependence across pointwise test statistics and to the pattern of the true signal. The performance of the two testing methods will be illustrated by applications to significance analysis of ElectroEncephalogram curves in Event-Related Potentials (ERP) designs and by SNPset approaches of Genome Wide Association Studies for genetic epidemiology issues. We also discuss the applications of the former general principles to prediction in high-dimension.

2019 ABS Summer School on Bayesian Demography (Como, Italy)
by Consonni Guido 29 Nov '18

29 Nov '18

We are glad to announce that the 2019 Applied Bayesian Statistics Summer School (16th edition) will be held in the magnificent Villa del Grumello, Como (Italy) along the Lake Como shore. BAYESIAN DEMOGRAPHY 24-28 June, 2019 Lecturers: Adrian Raftery and Hana Ševcíková University of Washington, Seattle, USA Further details are provided below. Guido Consonni and Fabrizio Ruggeri ABS19 Directors Raffaele Argiento ABS19 Executive Director ---------------------------------------------------------------- ******************************* * ABS19 * ******************************* Applied Bayesian Statistics School BAYESIAN DEMOGRAPHY Villa del Grumello, Como, Italy 24-28 June, 2019 Lecturers: - Adrian Raftery, the Boeing International Professor of Statistics and Sociology - Hana Ševcíková, Senior Research Scientist Center for Statistics and the Social Sciences, Center for Studies in Demography and Ecology, University of Washington, Seattle, USA The School webpage is http://web.mi.imati.cnr.it/conferences/abs19/index.html Registration is now open. Please note that the conference room allows only for a very limited number of participants. COURSE OUTLINE Population projections have until recently usually been done deterministically. Recently, the United Nation Population Division adopted a probabilistic approach to project fertility, mortality and population for all countries. In this approach, the total fertility rate and female and male life expectancy at birth are projected using Bayesian hierarchical models estimated via Markov Chain Monte Carlo. They are then combined with a cohort component model, which yields probabilistic projection for any quantity of interest. The methodology is implemented in a suite of R packages, which has been used by the UN analysts to produce the most recent revision of the World Population Prospects. This course will teach the theory and practice of Bayesian probabilistic projections. Ideas of the Bayesian hierarchical modeling for the three main components of population change, fertility, mortality and migration, will be explained. In hands-on exercises, students will become familiar with the functionality of the R packages. PRACTICAL INFORMATION The school will replicate the successful format of the previous years, and will feature lectures and practical sessions, as well as participants' talks. It will start on Monday after lunch and end on Friday before lunch; Wednesday afternoon is free. Accommodation is available either at the Villa guesthouse or in downtown hotels (info will appear soon on the website). Como can be easily reached by train from Milan and its airports. More details are available on the website.

seminario Felix Liebrich - 22 novembre - REMINDER
by Emanuela Rosazza 20 Nov '18

20 Nov '18

Si avvisa che il giorno giovedì 22 novembre alle ore 14 presso l’Università di Milano- Bicocca (via degli Arcimboldi 8 - edificio U7, quarto piano- aula 4026) si terrà il seguente seminario: Speaker: Felix-Benedikt Liebrich (LMU Muenchen, Germany) Titolo: “Sharing utility and risk under (partial) law-invariance” Abstract: The so-called risk sharing problem has two variants: (1) How can an aggregation of individual utilities within a system of agents be maximised by means of distributing a certain good, or (2) how can an aggregation of individual risks be minimised by means of redistributing a certain loss the system incurs? The problem has a long history in economics and financial mathematics, and solving it in relevant infinite dimensional spaces is very challenging. Substantial results have been obtained in the context of Pareto efficiency of such sharing schemes when law-invariant (risk) preferences are involved. These rank Savage acts -- random variables -- in a way which only depends on their distribution under a fixed reference probability measure. It was shown that Pareto efficient allocations (i.e. sharing schemes) exist. For problem (1) of maximising aggregated utility, the talk presents a unifying framework in which solutions to the risk sharing problem can be found. As applications, we will discuss the existence of weakly Pareto efficient allocations, Pareto efficient allocations, and core allocations. In a second part, we solve the risk sharing problem (2) for a wide class of capital requirements determining individual risks. These will not be law-invariant functionals, but build on a law-invariant ingredient. The talk is based on joint work with Gregor Svindland. Tutti gli interessati sono invitati a partecipare. Un saluto cordiale, Emanuela ******************************************************************************************* Emanuela Rosazza Gianin Dipartimento di Statistica e Metodi Quantitativi Università di Milano-Bicocca Edificio U7 – 4° Piano Via Bicocca degli Arcimboldi, 8 20126 Milano Tel. 02 64483208 Fax. 02 64483105 e-mail: emanuela.rosazza1(a)unimib.it *******************************************************************************************

A Summer Day in Probability and Statistical Physics
by Francesca Romana Nardi 16 Nov '18

16 Nov '18

Carissimi, la prossima giornata di seminari sara` il 14 Settembre 2018. Ricordo che ciascuno oratore fara` una lezione introduttiva e divulgativa di 45 minuti pensata proprio per i non esperti, seguita da altri 45 minuti di tipo seminario (vedi programma). Maggiori informazioni e aggiornamenti sulle giornate passate e future sono reperibili alla pagina web che vi invitiamo a visitare periodicamente. http://web.math.unifi.it/users/fnardi/seminari/ A SUMMER DAY IN PROBABILITY AND STATISTICAL PHYSICS University of Florence Friday 14 September 2018 Lecturers: Stefano Olla (Paris) and Raúl Rechtman (Mexico) Location: Aula Magna di Via S. Gallo 10, Firenze Prof. Stefano Olla (Universite` Paris Dauphine) Title: Hyperbolic Hydrodynamic Limits Abstract: I will present a review of old and new results (and open problems) concerning scaling limits for conservation laws in the hyperbolic space-time scale, for a system of anharmonic oscillators with external boundary tension. The macroscopic equation is given by the compressible Euler system, with corresponding boundary conditions. The problem is particularly challenging when shockwaves are present. Some results exists when the microscopic dynamics is perturbed by a conservative stochastic viscosity. Works in Collaboration with Stefano Marchesani (GSSI) and Lu Xu (CEREMADE). Prof. Raúl Rechtman, (Universidad Nacional Autónoma de México) Title: Chaos and damage spreading in a probabilistic cellular automaton Abstract: Deterministic Boolean cellular automata (CA) are discrete maps F:BN → BN, B={0,1}, x(t+1)=F(x(t)) with x ϵ BN, N large and t=0,1,… . The vector x is the state of the cellular automaton with components xi,, i=0,…,N-1 the state of cell I. Each cell is connected to others, generally in a uniform and local way, and one can define an adjacency matrix aij=1 is cell j is connected to cell i and zero otherwise. The global map F is determined by the parallel application of a local function f, such that xi(t+1) = f(vi(t)), where vi denotes the state of cells connected to cell i. Deterministic CA are thus the discrete equivalent of dynamical systems, and many concepts like trajectory (the sequence of configurations x(t)), fixed points and limit cycles can be used. There are cellular automata for which a small modification in an initial configuration propagates to the whole system, a situation similar to chaos in continuous systems, and indeed one can extend the concept of the largest Lyapunov exponent to deterministic CA using Boolean derivatives. One of the main inconvenient is that these systems do not have continuous parameters to be tuned, in order to study bifurcations. In probabilistic cellular automata, the function f (and thus F) is defined in terms of transition probabilities so that deterministic CA can be seen as the extreme cases of probabilistic ones, when the transition probabilities are either zero or one. Probabilistic CA can be seen also as Markov chains, and one can observe interesting phase transitions after changing the transition probabilities that are therefore continuous control parameters. A realization of a specific trajectory is determined by the extraction of one or more of random numbers for each cell. By extracting these numbers at the beginning of the simulation, for all cells and all times, one converts a probabilistic CA into a deterministic one, running over a quenched random field. One can therefore use the concepts of deterministic CA, like damage spreading and maximum Lyapunov exponent also for probabilistic CA, with the advantage of having the possibility of fine-tuning the control parameters. In particular, we investigate a probabilistic cellular automaton which can be considered an extension of a model in the universality class of directed percolation models, but with two absorbing states. In the first part of the talk all the concepts mentioned above are defined and in the second part, the probabilistic cellular automaton is studied numerically. We show that the phase transitions when the order parameter is the average damage do not coincide with those found for the Lyapunov exponent and the reason of this is the presence of absorbing states.
