A SPRING DAY IN PROBABILITY AND STATISTICAL PHYSICS
by Francesca Romana Nardi 30 Jan '18

30 Jan '18

Carissimi, stiamo cercando di organizzare in Italia, sulla falsariga del M. Kac Seminar in Olanda, una serie di incontri di probabilita` e delle sue applicazioni alla Fisica, Biologia e Scienze sociali, per stimolare lo scambio di idee e offrire ai piu` giovani l'opportunita` di venire a contatto con un ampio panorama di temi di ricerca. E` con grande gioia che vi comunico che il primo di questi eventi si terra` venerdì 26 Maggio 2017 a Firenze, in un'aula universitaria vicino alla stazione di S. Maria Novella. Sara` un'occasione per goderci una giornata scientifica insieme e per esplorare le possibilita` e le modalita` piu` opportune per ripetere questo tipo di incontri. Di seguito trovate i dettagli della giornata del 26 Maggio, che vedra` come oratori R. Fernandez (University of Utrecht, Olanda) e R. Morris (IMPA Instituto Nacional de Matemática Pura e Aplicada Rio de Janeiro, Brazil). A SPRING DAY IN PROBABILITY AND STATISTICAL PHYSICS University of Florence Friday 26 May 2017 Lecturers: R. Fernandez (Utrecht) and R. Morris (IMPA). Location: Aula Magna di Via S. Gallo 10, Firenze Prof. Roberto Fernandez Title: Signal description: process or Gibbs? Abstract: The distribution of signals such as spike trains is naturally modeled through stochastic processes where the probability of future states depend on the pattern of past spikes. Mathematically, this corresponds to distributions *conditioned on the past*. From a signal-theoretic point of view, however, one could wonder whether a more efficient description could be obtained through the simultaneous conditioning of past *and* future. Furthermore, such a formalism could be appropriate when discussing string without a particular "time" order, such as the distribution of DNA nucleotides, or even issues related to anticipation and prediction in neuroscience. On the mathematical level this double conditioning would correspond to a Gibbsian description analogous to the one adopted in statistical mechanics. In this talk I will introduce and contrast both approaches ---process and Gibbsian based--- reviewing existing results on scope and limitations of them. Prof. Robert Morris Title: Monotone cellular automata Abstract: Cellular automata are interacting particle systems whose update rules are local and homogeneous. Since their introduction by von Neumann almost 50 years ago, many particular such systems have been investigated, but no general theory has been developed for their study, and for many simple examples surprisingly little is known. Understanding their (typical) global behaviour is an important and challenging problem in statistical physics, probability theory and combinatorics. In this talk I will outline some recent progress in understanding the behaviour of a particular (large) family of monotone cellular automata -- those which can naturally be embedded in d-dimensional space -- with random initial conditions. For example, in the case where a site updates (from inactive to active) if at least r of its neighbours are already active, these models are known as bootstrap percolation, and have been extensively studied for various specific underlying graphs. Apart from their inherent mathematical interest, the study of these processes is motivated by their close connection to models in statistical physics, and I will discuss some applications to a family of models of the liquid-glass transition known as kinetically constrained spin models. Program: 11.00-11.45 Introductory lecture: R. Fernandez 11.45-12.00 Break 12.00-12.45 Seminar: R. Fernandez 13.00-14.30 Lunch 14.30-15.15 Introductory lecture: R.

=========================================================== 2 postdoc positions in Machine Learning (1 year, renewable up to 3 years) Institution: RIST - Romanian Institute of Science and Technology, Cluj-Napoca Keywords: Deep Learning, Reinforcement Learning, Stochastic Optimization, Optimization over Manifolds, Information Geometry, Riemannian Geometry Application deadline: 30 July 2017 (applicants are encouraged to apply earlier) Salary: around 2190 euro net Official announcement: http://rist.ro/en/details/news/postdoc-positions-in-deep-learning-and-machi… =========================================================== Dear colleagues, the Romanian Institute of Science and Technology (RIST) has an opening for 2 postdoc positions, in the context of the DeepRiemann project “Riemannian Optimization Methods for Deep Learning”, funded by European structural funds through the Competitiveness Operational Program (POC 2014-2020). The appointments will be for 1 year, with possible extensions up to 3 years. The DeepRiemann project aims at the design and analysis of novel training algorithms for Neural Networks in Deep Learning, by applying notions of Riemannian optimization and differential geometry. The task of the training a Neural Network is studied by employing tools from Optimization over Manifolds and Information Geometry, by casting the learning process to an optimization problem defined over a statistical manifold, i.e., a set of probability distributions. The project is highly interdisciplinary, with competences spanning from Machine Learning to Optimization, Deep Learning, Statistics, and Differential Geometry. The objectives of the project are multiple and include both theoretical and applied research, together with industrial activities oriented to transfer knowledge, from the institute to a startup or spin-off of the research group. The positions will be part of the new Machine Learning and Optimization group http://luigimalago.it/group.html, which performs research at the intersection of Machine Learning, Stochastic Optimization, Deep Learning, and Optimization over Manifolds, from the unifying perspective of Information Geometry. The group is one of two newly-formed groups in Machine Learning at RIST, where about 20 new postdoctoral research associates and research software developers will be hired by 2018. The official job announcement can be seen here: http://rist.ro/en/details/news/postdoc-positions-in-deep-learning-and-machi… Informal inquiries can be sent to Dr. Luigi Malagò <malago(a)rist.ro>, principal investigator of the DeepRiemann project.

U7, 2° piano, aula 2061 __________________________________________________________ Abstract: In this presentation we illustrate a novel inferential approach to estimate time-varying parameters of locally stationary time series. This approach is based on costationary combinations, that is, time-varying deterministic linear combinations of locally stationary time series that are second-order stationary. We first review the theory of costationarity and formalize a Generalised Method of Moments estimator for the coefficient vectors. We then use this new framework to derive an estimator for the (time-varying) covariance of locally stationary time series and we show that the new covariance estimator is more efficient than classical estimators exclusively based on the evolutionary cross-periodogram. We confirm our theoretical findings through a simulation experiment. We then present a new analysis of financial log-returns showing that our new estimator is capable to highlight well known economic shocks. As a second example of our approach we finally discuss forecasting of locally stationary time series based on costationary combinations. __________________________________________________________ Cordiali saluti Fulvia Pennoni -- Fulvia Pennoni Department of Statistics and Quantitative Methods University of Milano-Bicocca http://www.statistica.unimib.it/utenti/pennoni/
