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. ..

de Finetti Risk seminar - november 2015
by Emanuela Rosazza 04 Nov '15

04 Nov '15

On behalf of the Scientific Committee of the de Finetti Risk Seminars, we are glad to invite you to participate at the following Lecture Title: Dynamic programming approach to Principal-Agent problems NIZAR TOUZI Ecole Polytechnique, Paris - France Abstract: We consider a general formulation of the Principal-Agent problem from Contract Theory, on a finite horizon. We show how to reduce the problem to a stochastic control problem which may be analyzed by the standard tools of control theory. In particular, Agent’s value function appears naturally as a controlled state variable for the Principal’s problem. Our argument relies on the Backward Stochastic Differential Equations approach to non-Markovian stochastic control, and more specifically, on the most recent extensions to the second order case. LOCATION: The seminar will be held on Wednesday, November 18, at 18.00, Aula di rappresentanza, Dept. of Mathematics, Milano University, Via C. Saldini 50, Milano. A refreshment will be offered at 17.30. Scientific Committee Prof. Simone Cerreia-Voglio (Univ. Bocconi) Prof. Marco Frittelli (Univ. degli Studi di Milano) Prof. Fabio Maccheroni (Univ.

Seminario di Economia e Probabilita' a RM1
by Fabio Spizzichino 01 Nov '15

01 Nov '15

La Dr.ssa Eleonora Perversi (Dipartimento di Matematica, Universita' di Pavia) terrà, presso il Dipartimento di Matematica dell'Universita' La Sapienza, un seminario su *Inequality and risk aversion in economies open to altruistic attitudes* Mercoledi' 4 Novembre, ore 14.00, Aula Picone Dipartimento di Matematica, Piazzale A. Moro, Roma Tutte le persone interessate sono invitate ad intervenire Fabio Spizzichino Abstract: In recent years there has been a great interest in the phenomenon of economic inequality, especially in relation to its connection with other important aspects of an advanced economy, for example attitude towards risk, growth, financial developments, and so on. In this talk, based on a joint work with Eugenio Regazzini, I will introduce a model for the surplus/deficit distribution, which points out a relationship between agents' risk aversion and inequality. More precisely, on the one hand, the long-time surplus/deficit distribution turns out to be a weak Pareto law whose exponent is given by an affine transformation of the agents relative risk aversion index, supposed to be the same for every agent. On the other hand, it is proved that concentration in a weak Pareto law can be measured through a function of its exponent. This way, a link is established between inequality and risk aversion. Finally, some feasible actions of economic policies suitable for the control of inequality are derived.

Peano" dell'Università degli Studi di Torino, Via Carlo Alberto 10, Il Prof. ENRICO SCALAS (Department of Mathematics, University of Sussex, UK) terrà un seminario dal titolo EXACTLY-SOLVABLE NON-MARKOVIAN DYNAMIC NETWORK Abstract: Non-Markovian processes are widespread in natural and human-made systems, yet explicit modelling and analysis of such systems is underdeveloped. In this letter we consider a dynamic network with random link activation and deletion (RLAD) with non-exponential inter-event times. We study a semi-Markov random process when the inter-event times are heavy tailed Mittag-Leffler distributed, thus considerably slowing down the corresponding Markovian dynamics and study the system far from equilibrium. We derive an analytically and computationally tractable system of forward equations utilizing the Caputo derivative for the probability of having a given number of active links in the network. http://journals.aps.org/pre/abstract/10.1103/PhysRevE.92.042801 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

Politecnico di Milano - Seminari Jim Ramsay e Michelle Carey
by Laura M. Sangalli 28 Oct '15

28 Oct '15

Si avvisa che in data 6-11-2015, alle ore 10:30 precise, presso l'Aula Seminari "F. Saleri" VI piano - Dipartimento di Matematica, Politecnico di Milano, nell'ambito delle iniziative MOX, si svolgeranno i seguente seminari: ore 10:30 Jim Ramsay, McGill University, Exploring Functional Data with Dynamic Models ore 11:30 Michelle Carey, McGill University, Data2PDE: an iterative scheme for obtaining data driven estimates of the parameters of PDEs defined over complex domains Seguono gli abstracts dei due seminari. Jim Ramsay Exploring Functional Data with Dynamic Models Discrete observations of curves are often smoothed by attaching a penalty to the error sum of squares, and the most popular penalty is the integrated squared second derivative of the function that fits the data. But it has been known since the earliest days of smoothing splines that, if the linear differential operator D^2 is replaced by a more general differential operator L that annihilates most of the variation in the observed curves, then the resulting smooth has less bias and greatly reduced mean squared error. This talk will show how we can use the data to estimate such an operator. The differential equation estimated in this way is already an interesting model for the data that represents the dynamics of the processes being estimated. But, in addition to the advantages in bias and MSE, it emerges that exciting new ways of representing the data emerge that use an orthogonal basis system defined by the estimated operator. M. Carey Data2PDE: an iterative scheme for obtaining data driven estimates of the parameters of PDEs defined over complex domains Spatial data are abundant in many scientific fields, some examples include; satellite images of the earth, temperature readings from multiple weather stations and the spread of an infectious disease over a particular region. In many instances the spatial data are accompanied by mathematical models expressed in terms of partial differential equations (PDEs). These PDEs determine the theoretical aspects of the behaviour of the physical, chemical or biological phenomena considered. The parameters of the PDEs are typically unknown and must be inferred from expert knowledge of the phenomena considered. In this talk I will discuss extending the profiling with parameter cascading procedure outlined in Ramsay et al (2007) to incorporate PDE parameter estimation. Furthermore, following from Sangalli et al. (2013) the estimation procedure is extended to include nite element methods (FEMs). This allows the proposed method to account for attributes of the geometry of the physical problem such as irregular shaped domains, external and internal boundary features and strong concavities. Thus this talk introduces a methodology for data driven estimates of the parameters of PDEs dened over complex domains. Tutti gli interessati sono invitati a partecipare.

PIETRO CAPUTO - GIOVEDI 29 - TOR VERGATA - CICLO SEMINARI PASCAL

Ciclo di Seminari - Progetto ERC grant PASCAL (Probabilistic and Statistical Techniques for Cosmological Applications) Giovedi` 29 ottobre ore 15:00 Aula Dal Passo Dipartimento di Matematica Università di Roma Tor Vergata Prof. Pietro Caputo Dipartimento di Matematica e Fisica, Università Roma Tre Titolo: Dynamical phase transition in random lattice triangulations Abstract: We consider lattice triangulations, i.e., triangulations of the integer points in Euclidean plane. Our focus is on random triangulations in which a triangulation \sigma has weight \lambda^{|\sigma|}, where \lambda is a positive real parameter and |\sigma| is the total length of the edges in \sigma. Empirically, this model exhibits a phase transition at \lambda=1 (corresponding to the uniform distribution): for \lambda<1 distant edges behave essentially independently, while for \lambda>1 very large regions of aligned edges appear. We substantiate this picture as follows. For \lambda<1 sufficiently small, we show that correlations between edges decay exponentially with distance (suitably defined), and also that the Glauber dynamics, namely the local Markov chain based on flipping edges, is rapidly mixing (in time polynomial in the number of edges in the triangulation). By contrast, for \lambda>1 we show that the mixing time is exponential. For thin rectangular regions we obtain sharp mixing time bounds for all values of \lambda<1. This is joint work with F. Martinelli, A. Sinclair and A. Stauffer Tutti gli interessati sono invitati a partecipare. .

Doctoral Seminar at LUISS
by Marco Scarsini 27 Oct '15

27 Oct '15

This is to invite you to our next doctoral seminar, on Thursday, October 29th, from 13:00 to 14:00 in room 405b. The speakers is Anna Zseleva (Maastricht University). The work presented will be: Title: Zero-sum games with charges Abstract: We consider two-player zero-sum games with infinite action spaces and bounded payoff functions. The players' strategies are finitely additive probability measures, called charges. Since a strategy profile does not always induce a unique expected payoff, we distinguish two extreme attitudes of players. A player is viewed as pessimistic if he always evaluates the range of possible expected payoffs by the worst one, and a player is viewed as optimistic if he always evaluates it by the best one. This approach results in a definition of a pessimistic and an optimistic value for each player. We provide an extensive analysis of the relation between these values, and connect them to the classical values. In addition, we also examine existence of optimal strategies with respect to these values.
