Apologies for cross posting --------------------------------- SEMINARIO DI MATEMATICA APPLICATA Giovedi 25 Febbraio 2016, ore 10.30 Aula Rappresentanza, Dipartimento di Matematica (Via Saldini 50, Milano) Robust statistical techniques for the analysis of high dimensional gene expression data Dr. Aurora Torrente Gregorio Millan Institute Escuela Politecnica Superior Universidad Carlos III de Madrid ABSTRACT Microarray and Next Generation Sequencing experiments provide data on the expression level of thousands of genes simultaneously, suggesting several serious challenges in the pre-processing, management and analysis of these high dimensional datasets. In this talk, we will describe some robust statistical tools, based on the concept of functional data depth, which measures the centrality of a function within a sample. These techniques include, for example, the scale curve, as a way to visualise the dispersion of a set of multivariate observations, and supervised classifications techniques, to assign new observations to one of a given set of (known) groups. When these tools make use of the so-called Modified Band Depth, adapted to high-dimensional data, they prove to be very efficient and of low computational cost, specially when a suitable implementation is considered. The use of these techniques will be illustrated on real gene expression data. La S.V. e` cordialmente invitata. ----------------------------------------------------------------------- Home page del seminario: http://www.mat.unimi.it/users/veeser/sma/ Il seminario e` organizzato da: - Dipartimento di Matematica dell'Universita` di Milano, - Scuola di Dottorato in Scienze Matematiche. -- ------------------------------------ Alessandra Micheletti Associate Professor - Probability and Mathematical Statistics Dept. of Mathematics Università degli Studi di Milano via Saldini 50, 20133 Milano, Italy phone: +39-02503-16130 fax: +39-02503-16090 http://users.mat.unimi.it/users/michel <http://www.mat.unimi.it/users/michel>

********************************************************************* SEMINARI DI PROBABILITA' E STATISTICA MATEMATICA DIPARTIMENTO DI MATEMATICA "G. PEANO" UNIVERSITA' DEGLI STUDI DI TORINO ********************************************************************* Venerdì 4 Marzo 2016 alle ore 15:00 in Aula C presso il Dipartimento di Matematica "G. Peano" dell'Università degli Studi di Torino, Via Carlo Alberto 10, La Dott.ssa MARTA PITTAVINO (University of Zurich) terrà un seminario dal titolo "Modelling multivariate data with additive Bayesian networks" Abstract: Bayesian networks are a form of graphical model which derives from empirical data a directed acyclic graph describing the dependency structure between random variables. Especially, additive Bayesian networks (ABNs) extend the usual generalized linear models to multiple dependent variables without involving dimension reduction. Existing software for working with ABNs are useful for dealing with these models for heterogeneous applications in systems epidemiology and biology. However, limitations in terms of computation and feasibility can be still open challenges. In this talk, an introduction to ABN model will be provided, together with a description of the R package abn, whereby applications of these models to systems epidemiology and biology are showed. Moreover, a theoretical development will be presented as an initial step to overcome open questions. Specifically, the result of fitting an ABN to a data set is translated into optimizing the likelihood of observing the data under the studied model: the marginal likelihood (ABN network score). A novel conjugate prior distribution for ABNs models is introduced that helps us to address the goodness of fit computation and the posterior parameter estimation. Tutti gli interessati sono invitati a partecipare. -- Federico Polito Department of Mathematics University of Torino Via Carlo Alberto, 10 10123, Torino, Italy Email: federico.polito(a)unito.it Tel: +39 011 6702937 Web: www.federicopolito.it

16 Feb '16

Dear Colleagues, You are cordially invited to attend the Eighth International Workshop on Applied Probability (IWAP2016), which will take place in Toronto, Canada, on June 20-23, 2016. This will mark the first Canadian IWAP, following previous successful IWAPs held in Turkey (2014), Israel (2012), Spain (2010), France (2008), USA (2006), Greece (2004), and Venezuela (2002). The venue of IWAP2016 is located in the heart of vibrant downtown Toronto, and is easily accessible by road, rail, and air. For more details, please visit the conference website <http://iwap2016.com/>http://iwap2016.com . IWAP2016 aims to bring together researchers and scientists engaged in applied probability, covering methodology and applications from diverse fields such as mathematics, statistics, physics, computer science, economics, engineering, biology, chemistry, and social and health sciences. In addition to research presentations, there will be ample networking opportunities throughout the event. Abstracts for contributed presentations will be accepted until April 15, 2016. Research presenters will be invited to submit for journal publication in a special issue of Methodology and Computing in Applied Probability. Should you have any questions regarding IWAP2016, please feel free to contact <mailto:info@iwap2016.com>info(a)iwap2016.com. Yours sincerely, Wendy Lou & Joseph Glaz Co-Chairs of IWAP2016 --

TIME-VARYING SIS PREVALENCE IN NETWORKS: THEORY AND A NEW APPROXIMATE FORMULA 25 febbraio 2016 *Luogo:* Dipartimento di Matematica, via Sommarive, 14 - Povo (TN) - Aula Seminari *Ore* 10:00 *Relatore:* - *Piet Van Mieghem** (*TU Delft Olanda*)* *Abstract: * Currently, epidemic spreading processes on networks are popular to model diffusion phenomena in real-world networks. After reviewing some basics about the continuous-time SIS Markov process on networks, we will focus on the prevalence, the average fraction of infected nodes in the network. Based on a recent exact differential equation containing the Laplacian matrix of the underlying graph, the time dependence of the SIS prevalence is first studied and then upper and lower bounded by a new, explicit analytic function of time. Our new approximate formula obeys a Riccati differential equation and bears resemblence to the classical expression in epidemiology of Kermack and McKendrick (1927), but enhanced with graph specific properties, such as the algebraic connectivity, the second smallest eigenvalue of the Laplacian of the graph. A comparison with the N-Interwined Mean-Field Approximation (NIMFA) and simulations of the exact continuous-time Markovian SIS process on a graph exhibit the accuracy and the potential of the new analytic formula. *Referente: *Stefano Bonaccorsi
