Martedì 31 gennaio 2017 Seminari di Probabilità e Statistica Matematica Aula G, Dipartimento di Matematica, Sapienza Università di Roma Ore 14 Valentina Cammarota (Sapienza Università di Roma) On the critical values of random spherical harmonics. Abstract: We study the limiting distribution, in the high energy limit, of critical points and extrema of random spherical harmonics. In particular, we first derive the density functions of extrema and saddles and then we provide analytic expressions for the variances. Our arguments require a careful investigation of the validity of the Kac-Rice formula in nonstandard circumstances, entailing degeneracies of covariance matrices for first and second derivatives of the processes being analyzed. It is well known that after proper rescaling random spherical harmonics converge to Berry's random plane waves; in the second part of the talk we focus on the spatial distribution of critical points of random plane waves. Based on joint works with Dmitry Beliaev, Domenico Marinucci and Igor Wigman. Ore 15 Sokol Ndreca (University Center of Belo Horizonte) Abstract: In this talk we consider a stochastic point process $i + \xi_i$, where $i\in \mathbb{N}$ and the $\xi_i's$ are i.i.d exponential random variables with standard deviation $\sigma$. Some properties of this process are investigated. We then study a discrete time single server queueing system with this process as arrival process and deterministic unit service time. We obtain a functional equation of the bivariate probability generating function of the stationary distribution for the system. The functional equation is quite singular, does not admit simple solution. We find the solution of such equation on a subset of its set of definition. Finally we prove that the stationary distribution of the system decays super-exponentially fast in the quarter plane. The queueing model, motivated by air and railway traffic, has been proposed by Kendall and others some five decades ago, but no solution of it has been found so far. This is a joint work with Gianluca Guadagni, Carlo Lancia and Benedetto Scoppola. Tutti gli interessati sono invitati a partecipare. Per informazioni rivolgersi a piccioni(a)mat.uniroma1.it.

Seminario BOUCHERON
by Matteo Ruggiero 20 Jan '17

20 Jan '17

************************************************************************ STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO ************************************************************************ Venerdì 27 Gennaio 2017 alle ore 12:00, presso l’Aula Rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: Stéphane BOUCHERON (Université Paris-Diderot) CONCENTRATION INEQUALITIES IN THE INFINITE URN SCHEME FOR OCCUPANCY COUNTS AND THE MISSING MASS, WITH APPLICATIONS TO GOOD-TURING ESTIMATORS AND ADAPTIVE STATISTICAL TEXT COMPRESSION An infinite urn scheme is defined by a probability mass function over positive integers. A random allocation consists of a sample of N independent drawings according to this probability distribution where N may be deterministic or Poisson-distributed. We are concerned with occupancy counts, that is with the number of symbols with r or at least r occurrences in the sample, and with the missing mass that is the total probability of all symbols that do not occur in the sample. Without any further assumption on the sampling distribution, these random quantities are shown to satisfy Bernstein-type concentration inequalities. The variance factors in these concentration inequalities are shown to be tight if the sampling distribution satisfies a regular variation property. Among other applications, these concentration inequalities allow us to derive tight confidence intervals for the Good--Turing estimator of the missing mass. In statistical text compression, adaptive (or twice-universal) coding faces the following problem: given a collection of source classes such that each class in the collection has a non-trivial minimax redundancy rate, can we design a single code which is asymptotically minimax over each class in the collection? We deal with classes of sources over an infinite alphabet (that is with infinite urn schemes), that are characterized by a dominating envelope. We provide asymptotic equivalents for the redundancy of envelope classes enjoying a regular variation property. We construct a computationally efficient online code, which is shown to be adaptive, within a loglog(n) factor, over the collection of regularly varying envelope classes. 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. Cordiali saluti, Matteo Ruggiero --- Matteo Ruggiero University of Torino and Collegio Carlo Alberto www.matteoruggiero.it

ENBIS Spring Meeting on Predictive Maintenance and Reliability with Big and Complex Data
by antonio.pievatolo＠cnr.it 19 Jan '17

19 Jan '17

Call for papers *ENBIS Spring Meeting on Predictive Maintenance and Reliability with Big and Complex Data* Monastery of Schlägl in Upper Austria, from 28th to 30th May, 2017 Abstract submission deadline: *26 February 2017* Web page: http://www.enbis.org/activities/events/current/533_ENBIS_Spring_Meeting_201… Description The meeting will focus on predictive maintenance and reliability with big and complex data. Industrial statistics and in particular reliability engineering is a strongly growing field of interest as technical products determine more and more our daily life (communication, mobility, logistics, energy, nutrition, etc.). This dependence motivates the importance of high reliability of processes and devices. The 2017 ENBIS Spring Meeting will contribute to the discussion of current problems and challenges in reliability and maintenance and to the exchange of knowledge among experts from industry, consultancy and academia. The meeting will focus on the application of statistical methods in the contemporary big data and internet of things context, where the sustained flow of failure and maintenance data can be of great value for prognosis and decision making if properly integrated with data analytic methods. Contributions are welcome on the illustration of particularly challenging reliability and maintenance problems, as well as on methodologies such as stochastic modelling, association modelling and data analysis methods designed for big data. -- Dr Antonio Pievatolo IMATI-CNR http://www.imati.cnr.it/joomla/index.php/people?layout=edit&id=101
