Prof. Macci a Pisa
by RITA GIULIANO 02 Feb '18

02 Feb '18

Il Prof. Claudio Macci sara' ospite del Dipartimento di Matematica, Universita' di Pisa, nei giorni 15, 16 e 17 febbraio prossimi. Terra' un seminario il 15 febbraio alle ore 15 in Aula Seminari. TITOLO Asymptotic behavior of some hitting probabilities for sums of IID Gaussian random sets ABSTRACT In this article, we consider sequences of partial sums of iid Gaussian random sets (with respect to the Minkowski sum) and we study the asymptotic behavior of some hitting probabilities (of suitable sets of $R^d$) for these partial sums. We also illustrate the use of the importance sampling for the estimation of these hitting probabilities by Monte Carlo simulations. We obtain the analog of well-known results for level crossing probabilities of random walks, and we refer to a version of the classical Cramér’s Theorem in large deviations for random compact sets existing in the literature. Joint work with Barbara Pacchiarotti. Tutti gli interessati sono invitati Rita Giuliano

Tutti gli interessati sono invitati a partecipare. Dipartimento di Metodi e Modelli per l'Economia, il Territorio e la Finanza Facoltà di Economia, Sapienza Università di Roma Giovedì 15 febbraio Ore 14.00, auletta A, IV piano *A new approach to spatial entropy measures* L. Altieri, D. Cocchi, G. Roli Entropy is widely employed in many applied sciences to measure the heterogeneity of observations. Recently, many attempts have been made to build entropy measures for spatial data, in order to capture the influence of space over the variable outcomes. The main limit of these developments is that all indices are computed conditional on a single distance and do not cover the whole spatial configuration of the phenomenon under study. Moreover, most of them do not satisfy the desirable additivity property between local and global spatial measures. We compare some recent developments in this field to a new approach which achieves substantial innovations. Firstly, Shannon’s entropy may be decomposed into two terms: spatial mutual information, accounting for the role of space in determining the variable outcome, and spatial global residual entropy, summarizing the remaining heterogeneity carried by the variable itself. Secondly, both terms satisfy the additivity property, being sums of partial entropies measuring what happens at different distance classes. The new entropy measures are shown to be more informative and to answer a wider set of questions than the current proposals of the literature. A case study is presented with categorical lattice data, concerning the spatial heterogeneity of land use over the Emilia Romagna region.

A tutti gli interessati. SEMINAR ANNOUNCEMENT ON BIG DATA, OPTIMIZATION AND LEARNING /Prof. Andrea Lodi //(Department of Mathematical and Industrial Engineering, Polytechnique Montréal, Canada; Canada Excellence Research Chair in Data Science for Real-Time Decision-Making) / In this talk I review a couple of applications on Big Data that I personally like and I try to explain my point of view as a Mathematical Optimizer – especially concerned with discrete (integer) decisions – on the subject. I advocate a tight integration of Machine Learning and Mathematical Optimization (among others) to deal with the challenges of decision-making in Data Science. For such an integration I try to answer three questions: 1) what can optimization do for machine learning? 2) what can machine learning do for optimization? 3) which new applications can be solved by the combination of machine learning and optimization?

Expressions of interest in the broad areas of Economics, Management and Statistics
by Giovanni Puccetti 31 Jan '18

31 Jan '18

The Department of Economics, Management and Quantitative Methods (DEMM) seeks expressions of interest for junior (post-doc and assistant professor) and senior (associate professor) positions from candidates interested in working with us in the broad areas of Economics, Management and Statistics. The University of Milan is a major research and teaching institution located in one of Europe’s most thriving cities. It is ranked in the top 200 for Economics in the Shanghai Ranking of World Universities. According to RepEc, the Department of Economics, Management, and Quantitative Methods – DEMM is one of the top five departments of economics in Italy and in the top four percent in Europe. The recent Italian research evaluation exercise (VQR 2011-2014) placed DEMM among the top 10 departments in the area of economics, management and statistics in Italy. DEMM has also been the recipient of a generous competitive funding in the recent “Bando Dipartimenti di Eccellenza” grant, awarded by the Italian ministry of education (MIUR) and aimed at creating the Centre of Excellence in Economics and Data Science (CEEDS). Particular attention will be given to candidates with an excellent research record and showing the potential to cooperate with the current members of the department in pursuing DEMM’s strategy. Informal enquiries may be directed via mail to Francesca Cottone, francesca.cottone(a)unimi.it. Interested candidates are invited to submit a CV to francesca.cottone(a)unimi.it, together with a short motivation letter specifying for which position they intend to apply for. There is no formal deadline for the expression of interest but an early assessment is expected to start in the second half of February 2018. Successful applicants will be contacted to work on the application for post-doc (2+2 years), assistant (tenure-track) or associate (permanent) professor positions. Gross salary: €30,000-40,000 according to experience (post-doc), €38,500 (assistant professor), €51,000 (associate professor) per annum. Tax exemption: a four-year tax exemption on 90 percent of the salary is available according to the Italian tax law for those candidates who have been residing outside Italy for 2 years or more. This would result in the following net salary (approx.): €33,500 (assistant professor), €45,000 (associate professor) per annum.

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.
