One-day workshop on Algebraic Statistics
by Eva Riccomagno 27 Dec '16

27 Dec '16

Buongiorno a Tutti, Si informa che lunedi’ 23 gennaio presso il Dipartimento di Matematica dell’Universita’ di Genova, aula 705, si terra’ un workshop di Statistica Algebrica con il programma in calce. Gli interessati sono cordialmente invitati a partecipare. Cordiali saluti, Eva Riccomagno ore 10.:30 Gherardo Varando, Computational Intelligence Group, Department of Artificial Intelligence, Technical University of Madrid http://cig.fi.upm.es/CIGmembers/gherardo_varando <http://cig.fi.upm.es/CIGmembers/gherardo_varando> TITLE: Polynomial representations of Bayesian network classifiers ABSTRACT: We briefly review our previous works on how to define families of polynomial that sign-represent decision functions induced by Bayesian network classifiers (BNCs). We show how to use those representations to bound the number of decision representable by BNCs and to study some extensions of BNCs to multi-label classification problems. We then expose the connections with algebraic statistic and in particular with the algebraic representation of discrete probability and conditional independence models. We conclude with some possible future lines of research. ore 11:30 Luigi Malago', Romanian Institute of Science and Technology - RIST TITLE: On the Geometry of Neural Networks: from 20-year-old Amari's natural gradient to these days ABSTRACT: Artificial neural networks consist of interconnected computational units, called neurons, which act as mathematical functions. From a mathematical perspective, a neural network is commonly defined as a composition of non-linear weighted sums, which transform input vectors to output vectors. Equivalently, from a probabilistic perspective, given an unknown probability distribution for the inputs, the network encodes a parametric conditional probability distribution, where the parameters are given by the connection weights. Information Geometry studies the geometry of statistical models with tools from differential and Riemannian geometry. Not surprisingly, one of the first applications of Information Geometry was related to the training of neural networks using the natural gradient. Neural networks were quite promising in the 80s in the machine learning community, but later on other methods gradually became more popular. More recently, starting from 2011-12, neural networks and their use in deep learning architectures have become prominent, thanks to their state-of-the-art performance in several different fields. In this talk we review the geometry of neural networks from the perspective of Information Geometry after almost 20 years from its conception, and we present some more recent applications of natural gradient-based methods for the training of deep neural networks. ore 14:00 Giovanni Pistone, ', de Castro Statistics, Collegio Carlo Alberto, Moncalieri TITLE: Geometries of the Gaussian Model ABSTRACT: In Information geometry, it is possible to define a number of different geometrical structures on the full Gaussian model: the Fisher-Rao Riemannian Manifold (S.T. Skovgaard 1981), the Wasserstein Riemannian Manifold (A. Takatsu 2011), the Exponential and Mixture Affine manifolds (G. Pistone & C. Sempi 1995). We discuss the features of these geometries, including the second order properties (e.g. Hessians), with special emphasis of the Wasserstein case. This turns out to be a special case of a more general set-up introduced in 2001 by R. Otto. Applications, due to L. Malagò (in progress), are presented. ————————————————————————————— Prof. Eva Riccomagno Dipartimento di Matematica - Universita` degli Studi di Genova Via Dodecaneso, 35 - 16146 Genova - ITALIA Tel: +39 - 010 - 353 6938 Fax: +39 - 010 - 353 6960 www.dima.unige.it/~riccomag

Like in the past four years, the 2017 school will be held in the magnificent Villa del Grumello, in Como (Italy), on the Lake Como shore. Raffaele Argiento ABS17 Executive Director Guido Consonni and Fabrizio Ruggeri ABS17 Directors ------------------------------------------------------------------------ ******************************* * ABS17 * ******************************* Applied Bayesian Statistics School MODELING SPATIAL AND SPATIO-TEMPORAL DATA WITH ENVIRONMENTAL APPLICATIONS June 19-23, 2017 Villa del Grumello, Como, Italy Lecturer: Bruno Sanso', Professor of Statistics, University of California Santa Cruz https://users.soe.ucsc.edu/~bruno/ The conference webpage is >>>> web.mi.imati.cnr.it/conferences/abs17.html <<<< Registration is now open. Please note that the conference room allows only for a limited number of participants. The ABS17 Secretariat can be contacted at abs17(a)mi.imati.cnr.it COURSE OUTLINE This course is intended for students who have a background in statistical methods and modeling. The course is focused on models for data that are spatially referenced and that evolve in time. We will develop models for stochastic processes that are indexed at irregularly scattered, fixed, locations. We will look into the theoretical properties of those models as well as into the computational issues involved in the estimation of their parameters. We will extend the analysis of fields of spatial observations that are collected in time. In particular, we will consider dynamically varying process where space and time interact. Real-data applications of Bayesian methods with MCMC techniques will be illustrated. Day 1: Introduction to Bayesian methods and hierarchical models. Examples of spatially referenced data. Basic properties of Gaussian random fields. Graphical exploration of spatial fields. Day 2: Variograms. Examples of families of correlations functions. Bayesian approach to estimation and prediction of spatial random fields. Day 3: The big data problem: reduced rank models and other modern approaches to dimension reduction. Day 4: Spatio-temporal models. Dynamic linear models: integro-differential equations. Day 5: Extensions PRACTICAL INFORMATION The school will replicate the successful format of the previous years, and will feature lectures and practical sessions (run by a junior researcher), 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.
