******************************************************************* STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO ******************************************************************* Venerdi 20 Novembre 2015 alle ore 12:00, presso l’Aula Rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: Paul JENKINS (University of Warwick) EXACT SIMULATION OF THE WRIGHT-FISHER DIFFUSION The Wright-Fisher family of diffusion processes is a class of evolutionary models widely used in population genetics, with applications also in finance and Bayesian statistics. Simulation and inference from these diffusions is therefore of widespread interest. However, simulating a Wright-Fisher diffusion is difficult because there is no known closed-form formula for its transition function. In this talk I show how it is possible to simulate exactly from the scalar Wright-Fisher diffusion with general drift, extending ideas based on retrospective simulation. The key idea is to exploit an eigenfunction expansion representation of the transition function. This approach also yields methods for exact simulation from several processes related to the Wright-Fisher diffusion: (i) its moment dual, the ancestral process of an infinite-leaf Kingman coalescent tree; (ii) its infinite-dimensional counterpart, the Fleming-Viot process; and (iii) its bridges. This is joint work with Dario Spanò. 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

Da: peter.jacko(a)gmail.com [peter.jacko(a)gmail.com] per conto di Peter Jacko [p.jacko(a)lancaster.ac.uk] Oggetto: Multi-armed Bandit Workshop 2016 at STOR-i, Lancaster University, UK -------- Multi-armed Bandit Workshop 2016 at STOR-i, Lancaster University, UK Dates: 11-12 January 2016 Webpage: http://www.stor-i.lancs.ac.uk/research/Workshops/Multi-armed-Bandit-Workshop The STOR-i Centre for Doctoral Training, which is a joint venture of the Operational Research group at the Department of Managment Science and the Statistics group at the Department of Mathematics at Lancaster University with strong links to the industry, will be holding a specialist workshop on multi-armed bandits. Lancaster university has a long tradition of research on this topic and several STOR-i PhD students have contributed to it. The multi-armed bandit problem has become classic because of its extreme difficulty. Researchers from different fields, especially statistics, operational research, applied probability and computer science, have made theoretical contributions that in the recent years started gaining wider popularity in practice due to the huge modelling power of this problem. This workshop will provide a forum for stimulating discussions, especially across the approaches that have developed independently of each other. The list of invited speakers includes recognised experts on reinforcement learning bandits, restless bandits, non-parametric bandits, Bayesian bandits, etc., covering both theoretical advances and applications in information technology, business & management, communications networks, health care, etc. We are grateful to EPSRC for support of the series of specialed workshops at STOR-i and to the London Mathematical Society for additional support for this workshop, in particular for significantly enhanced support for UK PhD students. Important Dates Friday 20th November 2015: Abstract submission and student bursaries request deadline Monday 14th December 2015: Registration deadline Monday 11th - Tuesday 12 January 2016: Workshop Invited Speakers (confirmed) Alexandra Carpentier - University of Potsdam, Germany Chris Gamble - Google UK Kevin Glazebrook - Lancaster University, UK Michael N.

Seminario Dr. Cosetta Minelli - Mendelian Randomisation - 9 novembre 2015

Gentilissimi/e, vi invio un avviso di seminario, con preghiera di massima diffusione. Sede del seminario: Istituti Biologici 2, Università di Verona, strada Le Grazie 8 (VERONA). Distinti saluti, Alessandro Marcon Alessandro Marcon, PhD Unit of Epidemiology & Medical Statistics Department of Diagnostics and Public Health University of Verona Strada Le Grazie 8, 37134 Verona, Italy tel. +39 045 8027668 Avviso di SEMINARIO Lunedì 9 novembre 2015 (ore 13.00-13.45) Aula E - Istituti Biologici (Istituti Biologici 2, blocco B, secondo piano) Dr. Cosetta Minelli Senior Lecturer in Medical Statistics, National Heart and Lung Institute, Imperial College London *Mendelian randomization: * *The use of genes as instruments to strengthen causal inference in epidemiology* Mendelian randomization is an approach that uses genes as instrumental variables to derive unconfounded estimates of the effects of risk factors (e.g. biomarkers) on disease traits, and is therefore increasingly being used in epidemiology to distinguish causal from spurious associations. Since genes are randomly allocated at conception, genetic effects on a biomarker cannot be affected by classical confounding (e.g. lifestyle factors) or reverse causation (e.g. biomarker level being influenced by the presence of disease). Demonstration that a genetic variant known to modify the biomarker also modifies the disease trait represents indirect evidence of a causal biomarker-disease association. The validity of Mendelian Randomization, however, is based on instrumental variable assumptions, the most important being absence of pleiotropy. This talk will describe the approach, discuss ways to assess pleiotropy, highlight opportunities and challenges offered by available genome-wide data, and discuss its extension to the field of epigenetics (two-step epigenetic Mendelian randomization).

Ciclo di Seminari - Progetto ERC grant PASCAL (Probabilistic and Statistical Techniques for Cosmological Applications) Annuncio di Colloquium al Dipartimento di Matematica, Universita` di Roma Tor Vergata Mercoledi` 18 novembre 2015 in Aula Dal Passo Ore 15 Giovanni PECCATI (Universite' du Luxenbourg) Connecting and projecting random points: a gate to novel functional estimates Abstract: I will formulate two simple models of stochastic geometry: the first one involves the projection of a random Gaussian point on a closed convex cone, and the second one consists in the construction of a random graph on the plane. For each of them, I will explain how the fluctuations of several key quantities can be controlled by using functional inequalities, like Poincare', logarithmic Sobolev and information/transport estimates. The resulting bounds will allow us to present a number of quantitative results that are part of a growing body of literature focussing on probabilistic approximations via variational techniques, that have been successfully applied to fields as diverse as compressed sensing, the geometry of random fields on homogeneous spaces, polymer models, computer sciences and time series analysis. The presentation will be adapted to a general mathematical audience, and is based on a large number of contributions by many authors, spread over almost a decade. Ore 16: coffee break Ore 16:45 Seminario Alessandro Arlotto (Duke University) Finite Horizon Markov Decision Problems and a Central Limit Theorem for Total Reward Abstract: We prove a central limit theorem for a class of additive processes that arise naturally in the theory of finite horizon Markov decision problems. The main theorem generalizes a classic result of Dobrushin (1956) for temporally non-homogeneous Markov chains, and the principal innovation is that here the summands are permitted to depend on both the current state and a bounded number of future states of the chain. We show through several examples that this added flexibility gives one a direct path to asymptotic normality of the optimal total reward of finite horizon Markov decision problems. The same examples also explain why such results are not easily obtained by alternative Markovian techniques such as enlargement of the state space. Tutti gli interessati sono invitati a partecipare. ..

Si avvisa che nei giorni 9-11 dicembre il prof. Nizar Touzi dell'Ecole Polytechnique terrÃ un mini-corso dal titolo "Martingale Optimal Transport" presso il Dipartimento di Matematica dell'UniversitÃ di Pisa. L'abstract ed il calendario sono riportati di seguito. -------------------------------------------------------------- - MER 9/12: ore 16 - 18 (Aula riunioni) - GIO 10/12: ore 10 - 12 (Aula seminari) - GIO 10/12: ore 15 - 17 (Aula seminari) - VEN 11/12: ore 9 - 13 (Aula seminari) Abstract: We provide an introduction to martingale optimal transport. In the context of the one-period version of the problem, we establish the Kantorovitch duality, we discuss the existence for the primal and the dual problems, and we provide the martingale version of the cyclic monotonicity condition together with of the one-dimensional Brenier theorem. We finally show the connection between continuous-time martingale transport and the Skorohod embedding problem, and we provide some applications.
