seminario il 19 Dicembre al CNR-IMATI
by Antonella Bodini 04 Dec '14

04 Dec '14

Venerdi 19 dicembre, alle ore 11, presso la sede di Milano dell'IMATI Via Bassini 15, nella Sala Pentagonale al secondo piano, *Ting Wang* (Department of Mathematics and Statistics, University of Otago, New Zealand) presentera' un seminario dal titolo Modelling of seismic activity using Markov-modulated Hawkes process and its extensions. Abstract: Earthquakes are processes in which the internal workings are only observed indirectly, although the final effects are all too observable! Hidden Markov models (HMMs, a general statistical framework for modelling partially observed systems) are an intuitively attractive idea for analysing seismicity. I will introduce the Markov-modulated Hawkes process that we developed for investigating long-term patterns in seismicity rate. The catalogue of the Landers earthquake sequence, which included multiple mainshocks, was used as a case study. I will show how this model captures the cyclic parent-generating-offspring feature of the temporal behaviour of earthquakes. I will also discuss our current work on extending this temporal model by including spatial variation of the seismic activity and the earthquake magnitude. Our aim is to categorize spatiotemporal seismic hazards holistically, using the entire earthquake record in a selected region to identify patterns correlated with subsequent large earthquakes, rather than the traditional way of hunting for individual foreshocks. Tutti gli interessati sono invitati a partecipare. Cordiali saluti, Antonella. -- Dott.

A general framework to analyze these kinds of inexact data with statistical tools developed for Hilbertian random variables will be presented. Robust estimation in Hilbert spaces is specially relevant for its applications in the treatment of contaminated functional data. Specifically, the trimmed mean was already defined and analyzed under ideal conditions. However its estimation has not been efficiently implemented. An algorithm to compute the sample trimmed mean in Hilbert spaces is presented and its robust properties are briefly discussed. To show the performance of the algorithm some case studies concerning functional and fuzzy data will be presented.

Saldini 50, Milano *BRUNO GALERNE* (MAP5, Université Paris Descartes) terrà un seminario dal titolo *Random Fields of Bounded Variation and Computation of their Variation Intensity* ABSTRACT: The purpose of this talk is to define and characterize random fields of bounded variation, that is random fields with sample paths in the space of functions of bounded variation, and to study their mean total variation. We will mainly focus on the mean variation of random fields with stationary increments. We will show that this mean variation is proportional to the Lebesgue measure, and an expression of the constant of proportionality, called the variation intensity, will be established. This expression shows in particular that the variation intensity only depends on the family of two-dimensional distributions of the stationary increment random field. When restricting to random sets, the obtained results give generalizations of well-known formulas from stochastic geometry and mathematical morphology. The interest of these general results will be illustrated by computing the variation intensities of several classical stationary random field and random set models, namely Gaussian random fields and excursion sets, Poisson shot noises, Boolean models, dead leaves models, and random tessellations. Tutti gli interessati sono invitati a partecipare.

Peano" dell'Università degli Studi di Torino, Via Carlo Alberto 10, La Dott.ssa VALENTINA CAMMAROTA (Department of Mathematics, Università degli Studi di Roma "Tor Vergata") terrà un seminario dal titolo ON THE DISTRIBUTION OF THE CRITICAL VALUES OF RANDOM SPHERICAL HARMONICS Abstract: We study the limiting distribution of critical points and extrema of random spherical harmonics, in the high energy limit. In particular, we first derive the density functions of extrema and saddles; we then provide analytic expressions for the variances and we show that the empirical measures in the high-energy limits converge weakly to their expected values. 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 analysed.

More often than not, we misestimate risk, and do so unwittingly. I will illustrate such issues and share thoughts that have guided my current research. http://www.stats.uwo.ca/faculty/zitikis/main.htm <http://www.stats.uwo.ca/faculty/zitikis/main.htm> -----------------------------------------------------------------------------
