A SPRING DAY IN PROBABILITY AND STATISTICAL PHYSICS
by Francesca Romana Nardi 30 Jan '18

30 Jan '18

Carissimi, stiamo cercando di organizzare in Italia, sulla falsariga del M. Kac Seminar in Olanda, una serie di incontri di probabilita` e delle sue applicazioni alla Fisica, Biologia e Scienze sociali, per stimolare lo scambio di idee e offrire ai piu` giovani l'opportunita` di venire a contatto con un ampio panorama di temi di ricerca. E` con grande gioia che vi comunico che il primo di questi eventi si terra` venerdì 26 Maggio 2017 a Firenze, in un'aula universitaria vicino alla stazione di S. Maria Novella. Sara` un'occasione per goderci una giornata scientifica insieme e per esplorare le possibilita` e le modalita` piu` opportune per ripetere questo tipo di incontri. Di seguito trovate i dettagli della giornata del 26 Maggio, che vedra` come oratori R. Fernandez (University of Utrecht, Olanda) e R. Morris (IMPA Instituto Nacional de Matemática Pura e Aplicada Rio de Janeiro, Brazil). A SPRING DAY IN PROBABILITY AND STATISTICAL PHYSICS University of Florence Friday 26 May 2017 Lecturers: R. Fernandez (Utrecht) and R. Morris (IMPA). Location: Aula Magna di Via S. Gallo 10, Firenze Prof. Roberto Fernandez Title: Signal description: process or Gibbs? Abstract: The distribution of signals such as spike trains is naturally modeled through stochastic processes where the probability of future states depend on the pattern of past spikes. Mathematically, this corresponds to distributions *conditioned on the past*. From a signal-theoretic point of view, however, one could wonder whether a more efficient description could be obtained through the simultaneous conditioning of past *and* future. Furthermore, such a formalism could be appropriate when discussing string without a particular "time" order, such as the distribution of DNA nucleotides, or even issues related to anticipation and prediction in neuroscience. On the mathematical level this double conditioning would correspond to a Gibbsian description analogous to the one adopted in statistical mechanics. In this talk I will introduce and contrast both approaches ---process and Gibbsian based--- reviewing existing results on scope and limitations of them. Prof. Robert Morris Title: Monotone cellular automata Abstract: Cellular automata are interacting particle systems whose update rules are local and homogeneous. Since their introduction by von Neumann almost 50 years ago, many particular such systems have been investigated, but no general theory has been developed for their study, and for many simple examples surprisingly little is known. Understanding their (typical) global behaviour is an important and challenging problem in statistical physics, probability theory and combinatorics. In this talk I will outline some recent progress in understanding the behaviour of a particular (large) family of monotone cellular automata -- those which can naturally be embedded in d-dimensional space -- with random initial conditions. For example, in the case where a site updates (from inactive to active) if at least r of its neighbours are already active, these models are known as bootstrap percolation, and have been extensively studied for various specific underlying graphs. Apart from their inherent mathematical interest, the study of these processes is motivated by their close connection to models in statistical physics, and I will discuss some applications to a family of models of the liquid-glass transition known as kinetically constrained spin models.

We are glad to announce that the 2018 Applied Bayesian Statistics Summer School (15th edition) will be held in the magnificent Villa del Grumello, Como (Italy) along the Lake Como shore. BAYESIAN STATISTICAL MODELLING AND ANALYSIS IN SPORT 4-8 June, 2018 Lecturer: Kerrie MENGERSEN, Distinguished Professor of Statistics, Queensland University of Technology, Brisbane, Australia. Further details are provided below. Guido Consonni and Fabrizio Ruggeri ABS18 Directors Raffaele Argiento ABS18 Executive Director ------------------------------------------------------------------------ ******************************* * ABS18 * ******************************* Applied Bayesian Statistics School BAYESIAN STATISTICAL MODELLING AND ANALYSIS IN SPORT Villa del Grumello, Como, Italy 4-8 June, 2018 Lecturer: Kerrie MENGERSEN, Distinguished Professor of Statistics, Queensland University of Technology, Brisbane, Australia. The conference webpage is >>>> web.mi.imati.cnr.it/conferences/abs18.html <<<< Registration is now open. Please note that the conference room allows only for a limited number of participants. The ABS18 Secretariat can be contacted at fabrizio(a)mi.imati.cnr.it COURSE OUTLINE The aim of this course is to increase students' ability to develop Bayesian models and computational solutions for real problems in the world of sport. A case study based teaching approach will be taken for the course. Each day, students will be presented with one or two problems posed by Sports Institutes regarding aspects of athlete training for world games. Through participatory problem solving, the students will be challenged to learn about theory, methods and applications of a range of Bayesian models including mixtures, spatio- temporal models, hidden Markov models and experimental design, and computational approaches including Markov chain Monte Carlo and Approximate Bayesian Computation. This hands-on course pays equivalent attention to theory and application, foundation and frontiers in Bayesian modelling and analysis. While the focus of the case studies is on sport, both sporting novices and lovers of sports are welcome, noting that the learning obtained in the course will be widely applicable to many other areas. COURSE SCHEDULE Day 1: Lectures on introduction to Bayesian modelling and computation. Presentation of Problem 1: ranking and benchmarking athletes. Discussion and implementation of potential Bayesian hierarchical models and computational solutions. Communication of results. Day 2: Lectures on foundational Bayesian theory. Presentation of Problem 3: modelling swimmers' effective work per stroke. Discussion and implementation of potential Bayesian high dimensional regression models and computational solutions. Communication of results. Presentation of Problem 4: modelling cyclists' wearable data. Discussion and implementation of potential (marked) time series models and computational solutions. Communication of results. Day 3: Lectures on foundational Bayesian computation. Presentation of Problem 5: optimising athletes' resilience. Discussion and implementation of potential Bayesian mixture models to relate performance, fatigue and recovery. Communication of results. Day 4: Lectures on foundational Bayesian computation and frontier Bayesian theory. Presentation of Problem 6: optimal sampling strategies. Discussion and implementation of potential Bayesian experimental design methods for acquiring data from athletes. Presentation of Problem 7: using video data to compare planned and set play in team sports. Discussion and implementation of potential Bayesian spatio-temporal models. Communication of results. Day 5: Lectures on frontier Bayesian computation. Finalisation of problems 1-7. Extensions. Concluding remarks. PRACTICAL INFORMATION The school will replicate the successful format of the previous years, and will feature lectures and practical sessions (run by a junior researcher), as well as participants' talks. It will start on Monday after lunch and end on Friday before lunch; Wednesday afternoon is free. Accommodation is available either at the Villa guesthouse or in downtown hotels (info will appear soon on the website). Como can be easily reached by train from Milan and its airports. More details are available on the website.

Seminario C. Olivera @ UniTo
by Cristina Zucca 29 Nov '17

29 Nov '17

A tutti gli interessati. Lunedì 4 dicembre alle ore 14:30 in aula C presso il Dipartimento di Matematica "G. Peano" dell'Università degli Studi di Torino, Via Carlo Alberto 10, il Prof. Christian Olivera (Universita` di Campinas) terrà un seminario dal titolo: "On a class of stochastic transport equations for L^2_loc vector fields" Abstract: //In this talk we discuss the existence and uniqueness of solutions to a class of stochastic transport equations with irregular coefficients. Asking only boundedness of the divergence of the coefficients (a classical condition in both the deterministic and stochastic setting), we can lower the integrability regularity required in known results on the coefficients. This is based on a joint work with Ennio Fedrizzi and Wladimir Neves. -- Dr. Cristina Zucca Department of Mathematics University of Torino Via Carlo Alberto 10 10123 Torino, Italy tel: +39-011-6702850 fax: +39-011-6702878

seminar at LUISS
by Marco Scarsini 27 Nov '17

27 Nov '17

Tuesday December 5, at 12:00 room 209 LUISS Viale Romania 32 00197 Roma, ITALY Speaker: Tim Roughgarden (Stanford University) Title: Data-Driven Optimal Auction Theory Abstract: The traditional economic approach to revenue-maximizing auction design posits a known prior distribution over what bidders are willing to pay, and then solves for the auction that maximizes the seller's expected revenue with respect to this distribution. But where does this distribution come from? One obvious answer is from data, in the form of previous bids by comparable bidders in auctions for comparable items. We survey recent work that develops theory to help reason about questions such as: (i) How much data is necessary and sufficient to identify a near-optimal auction? (ii) What is the optimal way to use data? (iii) Are there fundamental trade-offs between auction complexity and auction optimality? ******************************************************* Marco Scarsini Dipartimento di Economia e Finanza LUISS Viale Romania 32 00197 Roma, ITALY URL: http://docenti.luiss.it/scarsini/

Seminario MLADEN SAVOV (presso Federico II - dip di Matematica)
by Bruno Toaldo 27 Nov '17

27 Nov '17

Lunedì 4 dicembre alle ore 15 in aula E al III livello del dipartimento di Matematica e Applicazioni "Renato Caccioppoli" dell'Università degli Studi di Napoli Federico II si svolgerà il seguente seminario: Speaker: Mladen Savov (Bulgarian Academy of Sciences) Titolo: Bernstein-gamma functions and exponential functionals of Lévy processes Abstract: In this talk we introduce a new class of special functions, called Bernstein-gamma functions. This simple class extends the classical Gamma function. We derive the Stirling asymptotic and describe the main analytic properties of the class of Bernstein-gamma functions. We then use these functions to evaluate explicitly the Mellin transform of the so-called exponential functionals of Levy processes which in turn allows a thorough study of these random variables. We also discuss the link between the Bernstein-gamma functions and many quantities related to one-dimensional self-similar Markov processes. The latter suggests that Bernstein-gamma functions can play the same role the Gamma function plays in the understanding of many continuous path stochastic processes. This is joint work with Pierre Patie (Cornel, US) Tutti gli interessati sono invitati a partecipare. Bruno Toaldo
