Numerical methods for stochastic models: control, uncertainty, quantification, mean-field
by Tiziano Vargiolu 30 Jan '17

30 Jan '17

Numerical methods for stochastic models: control, uncertainty quantification, mean-field July 17 - August 25, CIRM, Marseille http://smai.emath.fr/cemracs/cemracs17/ The goal of this event is to bring together scientists from both the academic and industrial communities and discuss these topics. During the first week, a classical summer school is proposed. It consists of several lectures given by leading scientists and related to the topics of the research projects. The remaining 5 weeks are dedicated to working on the rechearch projects, possibly after a morning seminar. Cemracs'17 will be the twenty-second of the series, devoted this year to the study of advanced numerical methods for the analysis of stochastic models associated with stochastic control problems, uncertainty propagation analysis or mean-field type interaction phenomena. These models are echoes many industrial applications (production optimization systems, life sciences, neuroscience, geophysics, fluid mechanics, risk management in finance, etc.). The main difficulty is the non-linearity or the high dimension of the problems encountered in practice. -- Stefano Pagliarani, DEAMS, Universit? di Trieste Via Tigor 22, 34124 Trieste, Italy Cell.

Indeed, the volatile demand, the strong seasonality of sales, the wide number of items with short life cycle or the lack of historical data, make the traditional forecasting models, based on time series, unsuitable or at least very difficult to implement. Therefore, researchers and practitioners have investigated other techniques such as Artificial Intelligence. The emergence of the “big data” era has also opened new opportunities and generated new issues. In this presentation, we propose an overview of the different constraints related to the sales forecasting in the fashion industry. Some examples are introduced to illustrate the problematics and the potential solutions. Finally, the new opportunities which could be explored are discussed. r. -- --------------------------------------------------- Roberta Sirovich Department of Mathematics G.

Avviso di seminario al Politecnico di Milano

Si avvisa che in data 3/2/2017, alle ore 12:00 precise, presso Aula seminari del terzo piano del dipartimento di Matematica del Politecnico di Milano, nell'ambito delle iniziative della sezione di Probabilità e Statistica Matematica, si svolgerà il seguente seminario: Titolo: MIsure invarianti per l'equazione stocastica di Navier-Stokes nel piano/ Invariant measures for Navier Stokes equation in the plane Relatore: Benedetta Ferrario, Universita' di Pavia Abstract: Si presenta un risultato di esistenza di una misura invariante per l'equazione di Navier-Stokes nel piano con forzante di tipo rumore bianco nel tempo. Poiche' si lavora in un dominio spaziale illimitato, l'immersione dello spazio di Hilbert H^1 in H^0 non e` compatta e questo richiede una tecnica diversa dal caso di dominio spaziale finito per la dimostrazione dell'esistenza di una misura invariante. Invece del metodo di Krylov e Bogoliubov si ricorre al metodo di Maslowski e Seidler (On sequentially weakly Feller solutions to SPDE's. Atti Accad. Naz. Lincei, Cl. Sci. Fis. Mat. Natur. Rend. Lincei (9) Mat. Appl. 10 (1999), no. 2, 69-78). Questo lavoro e` in collaborazione con Z. Brzezniak (Universita` di York). The existence of an invariant measure for 2d Navier Stokes with white noise (in time) forcing term is given. Due to the unboundedness of the domain a different technique in proving this existence result used. In fact, rather then using Krylov-Bogoliubov method we follow the approach introduced by Maslowsly and Seidler (On sequentially weakly Feller solutions to SPDE\'s. Atti Accad. Naz. Lincei, Cl. Sci. Fis. Mat. Natur. Rend. Lincei (9) Mat. Appl. 10 (1999), no. 2, 69-78). This is a joint paper with Z. Brzezniak, University of York. Tutti gli interessati sono invitati a partecipare.

Martedì 31 gennaio 2017 Seminari di Probabilità e Statistica Matematica Aula G, Dipartimento di Matematica, Sapienza Università di Roma Ore 14 Valentina Cammarota (Sapienza Università di Roma) On the critical values of random spherical harmonics. Abstract: We study the limiting distribution, in the high energy limit, of critical points and extrema of random spherical harmonics. In particular, we first derive the density functions of extrema and saddles and then we provide analytic expressions for the variances. Our arguments require a careful investigation of the validity of the Kac-Rice formula in nonstandard circumstances, entailing degeneracies of covariance matrices for first and second derivatives of the processes being analyzed. It is well known that after proper rescaling random spherical harmonics converge to Berry's random plane waves; in the second part of the talk we focus on the spatial distribution of critical points of random plane waves. Based on joint works with Dmitry Beliaev, Domenico Marinucci and Igor Wigman. Ore 15 Sokol Ndreca (University Center of Belo Horizonte) Abstract: In this talk we consider a stochastic point process $i + \xi_i$, where $i\in \mathbb{N}$ and the $\xi_i's$ are i.i.d exponential random variables with standard deviation $\sigma$. Some properties of this process are investigated. We then study a discrete time single server queueing system with this process as arrival process and deterministic unit service time. We obtain a functional equation of the bivariate probability generating function of the stationary distribution for the system. The functional equation is quite singular, does not admit simple solution. We find the solution of such equation on a subset of its set of definition. Finally we prove that the stationary distribution of the system decays super-exponentially fast in the quarter plane. The queueing model, motivated by air and railway traffic, has been proposed by Kendall and others some five decades ago, but no solution of it has been found so far. This is a joint work with Gianluca Guadagni, Carlo Lancia and Benedetto Scoppola. Tutti gli interessati sono invitati a partecipare. Per informazioni rivolgersi a piccioni(a)mat.uniroma1.it.

Seminario BOUCHERON

20 Jan '17

************************************************************************ STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO ************************************************************************ Venerdì 27 Gennaio 2017 alle ore 12:00, presso l’Aula Rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: Stéphane BOUCHERON (Université Paris-Diderot) CONCENTRATION INEQUALITIES IN THE INFINITE URN SCHEME FOR OCCUPANCY COUNTS AND THE MISSING MASS, WITH APPLICATIONS TO GOOD-TURING ESTIMATORS AND ADAPTIVE STATISTICAL TEXT COMPRESSION An infinite urn scheme is defined by a probability mass function over positive integers. A random allocation consists of a sample of N independent drawings according to this probability distribution where N may be deterministic or Poisson-distributed. We are concerned with occupancy counts, that is with the number of symbols with r or at least r occurrences in the sample, and with the missing mass that is the total probability of all symbols that do not occur in the sample. Without any further assumption on the sampling distribution, these random quantities are shown to satisfy Bernstein-type concentration inequalities. The variance factors in these concentration inequalities are shown to be tight if the sampling distribution satisfies a regular variation property. Among other applications, these concentration inequalities allow us to derive tight confidence intervals for the Good--Turing estimator of the missing mass. In statistical text compression, adaptive (or twice-universal) coding faces the following problem: given a collection of source classes such that each class in the collection has a non-trivial minimax redundancy rate, can we design a single code which is asymptotically minimax over each class in the collection? We deal with classes of sources over an infinite alphabet (that is with infinite urn schemes), that are characterized by a dominating envelope. We provide asymptotic equivalents for the redundancy of envelope classes enjoying a regular variation property. We construct a computationally efficient online code, which is shown to be adaptive, within a loglog(n) factor, over the collection of regularly varying envelope classes. 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.

ENBIS Spring Meeting on Predictive Maintenance and Reliability with Big and Complex Data
by antonio.pievatolo＠cnr.it 19 Jan '17

19 Jan '17

Call for papers *ENBIS Spring Meeting on Predictive Maintenance and Reliability with Big and Complex Data* Monastery of Schlägl in Upper Austria, from 28th to 30th May, 2017 Abstract submission deadline: *26 February 2017* Web page: http://www.enbis.org/activities/events/current/533_ENBIS_Spring_Meeting_201… Description The meeting will focus on predictive maintenance and reliability with big and complex data. Industrial statistics and in particular reliability engineering is a strongly growing field of interest as technical products determine more and more our daily life (communication, mobility, logistics, energy, nutrition, etc.). This dependence motivates the importance of high reliability of processes and devices. The 2017 ENBIS Spring Meeting will contribute to the discussion of current problems and challenges in reliability and maintenance and to the exchange of knowledge among experts from industry, consultancy and academia. The meeting will focus on the application of statistical methods in the contemporary big data and internet of things context, where the sustained flow of failure and maintenance data can be of great value for prognosis and decision making if properly integrated with data analytic methods. Contributions are welcome on the illustration of particularly challenging reliability and maintenance problems, as well as on methodologies such as stochastic modelling, association modelling and data analysis methods designed for big data. -- Dr Antonio Pievatolo IMATI-CNR http://www.imati.cnr.it/joomla/index.php/people?layout=edit&id=101

Our proof is based upon adecomposition of the Euler-Poincaré Characteristic into differentWiener-chaos components: we prove that its asymptotic behaviour isdominated by a single term, corresponding to the chaotic component oforder two. As a consequence, we show how the asymptotic dependence on the threshold level u is fully degenerate, i.e. the Euler-PoincaréCharacteristic converges to a single random variable times a deterministicfunction of the threshold. This deterministic function has a zero at theorigin, where the variance is thus asymptotically of smaller order. Ourresults can be written as an asymptotic second-order Gaussian KinematicFormula for the excursion sets of Gaussian spherical harmonics.Based on a joint work with Valentina Cammarota.* *Prossimo seminario: Valentina Cammarota, 31/1* *Tutti gli interessati sono invitati ad intervenire.* *Per richieste di informazioni scrivere a piccioni(a)mat.uniroma1.it.*

Following the paradigm of preferential attachment, these models offer a simple explanation to why power laws can be observed in real-life networks such as the world wide web. The basic rule is that when new nodes are introduced into the network, they prefer to establish connections to old nodes that already have many connections. In this project we will consider the preferential network model with fitness. Here, the classical preferential attachment mechanism is modified by equipping each node with a random fitness. This models the fact that not every new node in a real-life network has the same initial attractiveness. The aim of the project is to understand how this extra randomness modifies the structure of the network. The mathematical analysis is closely related to studying processes in random environment and in particular to non-homogeneous branching processes. > > The project will be based at the internationally recognised probability laboratory at the University of Bath and the PhD candidate would benefit from a vibrant research environment and the interaction with other postgraduate students and other specialists working on closely related topics. >

de Finetti Risk Seminar - January 24, 2017
by Emanuela Rosazza 17 Jan '17

17 Jan '17

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: Partial Differential Equations (PDEs) in Infinite Dimension: Economic and Financial models Fausto Gozzi LUISS, Italy ABSTRACT: "PDEs in Infinite Dimension" seems, already from the name, a very abstract and difficult subject. We aim to show how it can be very useful in treating, in particular, economic and financial models. We start by presenting some motivating problems in Economic and Finance (e.g. Growth and Pricing/Hedging) which can be naturally attacked using, as main mathematical tools, infinite dimensional PDEs. We then point out the state of the art on these kind of problems and present some recent results on them. Finally we will discuss the applicability of such results to the motivating problems and give some ideas on possible future developments. LOCATION: The seminar will be held on Tuesday, January 24, at 18.00, Aula di rappresentanza, Dept. of Mathematics, Milano University, Via C. Saldini 50, Milano. A refreshment will be offered at 19.00. Scientific Committee Prof. Simone Cerreia-Voglio (Univ. Bocconi) Prof. Marco Frittelli (Univ. degli Studi di Milano) Prof. Fabio Maccheroni (Univ.

----- Annuncio Seminario di Probabilità, Pisa ---- Dipartmento di Matematica, Università di Pisa Mercoledi, 18 gennaio, ore 11:00, Sala Riunioni. Seminario di Probabilità SPEAKER 1: Dario Trevisan, Universita di Pisa TITLE: A PDE approach to a 2-dimensional matching problem ABSTRACT: We prove asymptotic results for 2-dimensional random matching problems. In particular, we obtain the leading term in the asymptotic expansion of the expected quadratic transportation cost for empirical measures of two samples of independent uniform random variables in the square. Our technique is based on a rigorous formulation of the challenging PDE ansatz by S. Caracciolo et al. (Phys. Rev. E, 90, 012118, 2014) that linearizes the Monge-Ampère equation. Moreover, it provides a new approach to classical bounds due to Ajtai et al. (Combinatorica, 4, 1984). Joint work with L. Ambrosio and F. Stra. Dopo una pausa di circa 15min, proseguiamo con SPEAKER 2: Franco Flandoli, Università di Pisa TITLE: Sistemi di particelle (proseguimento): l'idea dell'equilibrio locale. ABSTRACT. Si prosegue la breve introduzione ai limiti macroscopici in diversi regimi approfondendo, pur solo euristicamente, il caso del limite idrodinamico, basato sull'idea di equilibrio locale. Tutti gli interessati sono invitati a partecipare. Per informazioni scrivere a carina.geldhauser(a)dm.unipi.it

Seminario di Tiziano De Angelis (School of Mathematics - The University of Leeds) Giovedi' 19 gennaio 2017 - ore 11:00 - aula 200 Università Cattolica del Sacro cuore, Milano, Dipartimento di di Discipline matematiche, Finanza matematica ed Econometria Viale Necchi, 9 - Milano TITLE: The dividend problem with a finite horizon ABSTRACT: We characterize the value function of the optimal dividend problem with a finite time horizon as the unique classical solution of a suitable Hamilton-Jacobi-Bellman equation. The optimal dividend strategy is realized by a Skorokhod reflection of the fund's value at a time-dependent optimal boundary. Our results are obtained by establishing for the first time a new connection between singular control problems with an absorbing boundary and optimal stopping problems on a diffusion reflected at an elastic boundary.

Indeed, dependent nonparametric priors are useful tools for drawing inferences on data that arise from different, though related, studies or experiments and for which the usual exchangeability assumption is not satisfied. The presentation will focus on models based on completely random measures, or suitable transformations thereof, that have an additive, a hierarchical and a nested structure. Some of their distributional properties relevant for prediction will be discussed. These theoretical results are, then, used for devising Markov chain Monte Carlo algorithms that will be implemented within some illustrative examples for analyzing data in the contexts of species sampling problems and survival analysis.* *Tutti gli interessati sono invitati ad intervenire.* *Per richieste di informazioni scrivere a piccioni(a)mat.uniroma1.it <piccioni(a)mat.uniroma1.it>.*
