Mini Course at GSSI on "Information Spreading, Consensus and Community Detection"
by clementi＠axp.mat.uniroma2.it 22 Jun '17

22 Jun '17

LECTURER: Andrea Clementi (Universita' degli Studi TOR VERGATA) PERIOD: 11-12/07/2017 LOCATION: GSSI, L'AQUILA, http://cs.gssi.infn.it/contacts/ SCHEDULING: http://cs.gssi.infn.it/phd-program/calendar/ TITLE: Gossip Algorithms for Information Spreading, Consensus and Community Detection ABSTRACT: The course will focus on a set of analytic tools to analyze some basic epidemic processes in networks. 1) We start giving the main concepts and results on spectral graph theory and on expander graphs. 2) We analyze the convergence time of randomized gossip algorithms in graphs having good expansion properties. 3) We analyze some simple probabilistic dynamics that achieve fast and stable consensus. 4) We consider distributed averaging processes on well-clustered graphs and look at the metastable phase in which the states of the nodes reflect the hidden clusters of the graph.

Politecnico di Milano - Seminario S. Castruccio
by Laura M. Sangalli 08 Jun '17

08 Jun '17

Si avvisa che in data 13-06-2017, alle ore 14:30 precise, presso l'Aula Seminari "F. Saleri" VI piano - Dipartimento di Matematica, Politecnico di Milano, nell'ambito delle iniziative MOX, si svolgerà il seguente seminario: Relatore: Stefano Castruccio, Newcastle University, UK Titolo: Stochastic Approximations of Complex Deterministic Models: Environmental Applications Sommario: Climate models are among the most used tools for impact assessment and policy making, and they are instrumental to obtain physically consistent projections of future climate. While it is of crucial importance to assess the sensitivity of such models to different input such as scenarios and parametrizations, a comprehensive analysis is not feasible due to computational and memory constraints. In this talk I will present new classes of global space-time statistical models (emulators) that can provide useful stochastic approximations to climate models. Emulators trained on a small set of model runs allow to perform sensitivity analysis with surrogate runs that are orders of magnitude faster to compute than the original climate model. I will also discuss some of my methodological research on global space-time statistical models, spanning from nonstationary Gaussian processes in the sphere x time domain that can account for land/ocean regimes and vertical profiles of temperatures, to skew-t processes for daily data. The large dimensionality of the model output, comprising of hundreds of millions data points, poses significant computational challenges, and in this talk I will also introduce a new sequential likelihood approximation that will allow scalable, parallelizable and asymptotically consistent inference for massive datasets. Tutti gli interessati sono invitati a partecipare. Cordiali saluti, Laura Sangalli -- Laura Maria Sangalli MOX - Dipartimento di Matematica Politecnico di Milano Piazza Leonardo da Vinci 32 20133 Milano - Italy tel: +39 02 2399 4554 fax: +39 02 2399 4568 email: laura.sangalli(a)polimi.it url: http://mox.polimi.it/~sangalli
