22 Nov '17

Mercoledi` 29 novembre alle ore 14:30 in aula Beltrami del Dipartimento di Matematica dell'Università di Pavia si svolgerà il seguente seminario: *Titolo* On a class of stochastic transport equations for L^2_loc vector fields *Relatore * Christian Olivera (Universita` di Campinas) *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. Tutti gli interessati sono invitati a partecipare.

Buongiorno, Martedi' 28 Novembre alle ore 14.00 ci sara' il seguente seminario in Aula di Consiglio (Dipartimento di Matematica, Universita' La Sapienza) : *Speaker: *Lorenzo Dello Schiavo (Institut für Angewandte Mathematik — Universität Bonn) *Title: *Two characterizations of Dirichlet—Ferguson measures *Abstract:* We consider the Dirichlet—Ferguson (DF) measure, a random probability on a locally compact Polish space X introduced by Ferguson in [1]. The measure has ever since found many applications, widely ranging from Bayesian non-parametrics to population genetics and stochastic dynamics of infinite particle systems. Firstly, we compute the characteristic functional of DF measures (addressing, if time permits, connections of these measures with Lie algebra theory and Pólya Enumeration Theory). Secondly, we prove a characterization of DF measures via a Mecke-type integral identity. Profiting of connections between DF measures and Poisson measures on configuration spaces, we argue how DF measures may be regarded as ‘canonical' measures on the space P(X) of Borel probability measures on X. Partly based on joint work with E. W. Lytvynov, University of Swansea, Wales, UK. [1] Ferguson, T. S., Ann. Stat. 1(2), pp. 209-230, 1973 Cordialmente, Alessandra -- ************************************************* Prof. Alessandra Faggionato http://www1.mat.uniroma1.it/~faggionato/ Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome Office 5, Phone (0039) 06 49913252 *************************************************

avviso di seminario

Il giorno 22 novembre, alle ore 14.30, in Aula C del Dipartimento di Matematica dell'Università degli Studi di Milano (via Saldini, 50) il prof. Matteo Barigozzi (London School of Economics, Londra) terrà un seminario dal titolo "Statistical analysis of high-dimensional time series via factor models" Abstract High-dimensional time series are among the most common type of dataset available today, and have entered current practice in many areas, including meteorology, genomics, chemometrics, complex physics simulations, biological and environmental research, finance and econometrics. The analysis of such datasets poses significant challenges, both from a statistical as well as from a numerical point of view. Some of the most successful procedures so far have been based on dimension reduction techniques and, more particularly, on high-dimensional factor models which have been developed, essentially, within time series econometrics. In this talk I will first review the main results on the representation of high-dimensional stationary times series as generalized dynamic factor models. Then I will present two different estimation techniques based on principal component analysis and on Kalman filtering. Both a time and a frequency domain approach are considered. Last, some extensions to non-stationary time series are also discussed. Tutti gli interessati sono invitati a partecipare ------------------------------------------- Carati Andrea, Dipartimento di Matematica, Via Saldini 50, 20133 Milano, Italy ------------------------------------------- tel: ++39/02/5835.6139 fax: ++39/02/5835.6090 -------------------------------------------

Final announcement: "Winter school on Energy Systems", Eindhoven (NL), 11-15 December 2017
by Zocca, Alessandro 15 Nov '17

15 Nov '17

Dear colleagues, we are pleased to announce that the “Winter school on Energy Systems” will take place in the week of December 11-15, 2017, in Eindhoven (NL). This winter school is part of a longer tradition of workshops, called YEQT (Young European Queueing Theorists), organized annually by the Eurandom research institute for Stochastics located at the Eindhoven University of Technology. This year we organize the 11th edition of the YEQT workshop on the theme "Stochastic modelling and analysis of energy networks". This year’s YEQT has a different structure than usual, being structured as a winter school. The workshop consists of several tutorials presented by six renowned researchers: - Ana Bušić (INRIA, Paris) - James Cruise (Heriot-Watt University) - Pär Holmberg (Research Institute of Industrial Economics, Stockholm) - Pierre Pinson (Technical University of Denmark) - John Moriarty (Queen Mary University of London) - Kostya Turitsyn (MIT) Next to the tutorials, there will be 16 research talks given by invited young researchers and a poster session. For more information, program, titles and abstracts, we welcome you to take a look at the winter school webpage: https://www.eurandom.tue.nl/events/workshops/2017/YEQT_XI_2017/YEQT_XI_2017… Registration is free, but compulsory for organizational purposes (see the link in the webpage). Best wishes, Alessandro Zocca (Caltech) Nicolas Gast (INRIA, Grenoble) Fiona Sloothaak (Eindhoven University of Technology)

Seminario di probabilità al Politecnico di Milano
by Fabio Zucca 15 Nov '17

15 Nov '17

Si avvisa che in data 23/11/2017, alle ore 10:00 precise, presso l'Aula Seminari del III piano del DIpartimento di Matematica del Politecnico di Milano si svolgerà il seguente seminario: Titolo: On segmentation with hidden, pairwise and triplet Markov models Relatore: Juri Lember, University of Tartu, Estonia Abstract: The well-known hidden Markov model (HMM) is a two-dimensional stochastic process (X,Y), where Y is a Markov chain and conditionally on Y, the X-process consists of independent random variables, the distribution of the random variable X_t depending on Y_t, only. Over the last decades, HMM's have become very popular stochastic models with applications to speech recognition, signal processing, linguistic, computational molecular biology and so on. Often the Y-process is unobserved (hidden) and the goal of the inference is to estimate its unobserved realization based on a realization of X-process. This task is called the segmentation problem and the standard ways to solve it is to use either maximum likelihood (so-called Viterbi) path or pointwise maximum likelihood (so-called PMAP) path. A trivial but important property of HMM is that the process Z=(X,Y) is itself a Markov process with a product state space. This observation allows naturally enlarge the class of HMM's to the class of pairwise Markov models (PMM) as follows: Z=(X,Y) is a PMM if Z has Markov property. Now it is clear that PMM's are a much larger class of models whose HMM\'s is just a little subclass. We briefly discuss several PMM's like Markov switching models and HMM's with dependent noise. It is important to note that if (X,Y) is a Markov process, then neither X nor Y need to have Markov property, but conditionally on X, the Y-process is Markov and vice versa. It turns out that many good properties of HMM's are mainly due to the Markov property of Z and hence these properties carry on to PMM's as well. In particular the well-known Viterbi and forward-backward algorithms apply and so standard segmentation approaches can be applied in the case of PMM's. Moreover, PMM-models provide a rather flexible and realistic model for the homology of random sequences. A triplet Markov model (TMM), introduced by W. Pieczynski, is a three-dimensional Markov process (X,Y,U), where, as previously, X stands for observations and Y is the hidden state sequence of interest. But in addition, there is another hidden component U. Since conditionally on U, the pair (X,Y) is an inhomogeneous PMM, the U-component models now the change of environment. It turns out that adding the U-component makes the model really flexible. We give a general approach to the risk-based segmentation problem that also applies for PMM's and TMM's, discuss the weaknesses standard approaches and introduce a way to overcome these problems. We also discuss the asymptotics of Viterbi segmentation for PMM\'s. Tutti gli interessati sono invitati a partecipare Fabio Zucca
