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.

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>.*

Prof. Simone Scotti [ LPMA, Université Paris Diderot ], will be hosted by the Computer Science Department of the University of Verona (Strada le Grazie, 15, Verona) https://goo.gl/maps/7uSSJWCiZtC2 the next 11st of January 2017 (Wednesday). He will give the seminar *Alpha-CIR Model with Branching Processes in Sovereign Interest Rate Modelling* scheduled at the *Green Hall*, *starting from 15:00*, with the following *Abstract* We introduce a class of interest rate models, called the alpha-CIR model, which gives a natural extension of the standard CIR model by adopting the alpha-stable Lévy process and preserving the branching property. This model allows to describe in a unified and parsimonious way several recent observations on the sovereign bond market such as the persistency of low interest rate together with the presence of large jumps at local extent. We emphasise on a general integral representation of the model by using random fields, with which we establish the link to the CBI processes and the affine models. Finally we analyse the jump behaviours and in particular the large jumps, and we provide numerical illustrations. This is a joint work with Ying Jiao and Chunhua Ma. *Here you can find more details*: http://www.di.univr.it/?ent=seminario&id=3847&lang=en Do not hesitate to contact me for further infos: luca.dipersio(a)univr.it Best, LuCa __ Luca Di Persio - PhD assistant professor of Probability and Mathematical Finance Dept.

One-day workshop on Algebraic Statistics
by Eva Riccomagno 27 Dec '16

27 Dec '16

Buongiorno a Tutti, Si informa che lunedi’ 23 gennaio presso il Dipartimento di Matematica dell’Universita’ di Genova, aula 705, si terra’ un workshop di Statistica Algebrica con il programma in calce. Gli interessati sono cordialmente invitati a partecipare. Cordiali saluti, Eva Riccomagno ore 10.:30 Gherardo Varando, Computational Intelligence Group, Department of Artificial Intelligence, Technical University of Madrid http://cig.fi.upm.es/CIGmembers/gherardo_varando <http://cig.fi.upm.es/CIGmembers/gherardo_varando> TITLE: Polynomial representations of Bayesian network classifiers ABSTRACT: We briefly review our previous works on how to define families of polynomial that sign-represent decision functions induced by Bayesian network classifiers (BNCs). We show how to use those representations to bound the number of decision representable by BNCs and to study some extensions of BNCs to multi-label classification problems. We then expose the connections with algebraic statistic and in particular with the algebraic representation of discrete probability and conditional independence models. We conclude with some possible future lines of research. ore 11:30 Luigi Malago', Romanian Institute of Science and Technology - RIST TITLE: On the Geometry of Neural Networks: from 20-year-old Amari's natural gradient to these days ABSTRACT: Artificial neural networks consist of interconnected computational units, called neurons, which act as mathematical functions. From a mathematical perspective, a neural network is commonly defined as a composition of non-linear weighted sums, which transform input vectors to output vectors. Equivalently, from a probabilistic perspective, given an unknown probability distribution for the inputs, the network encodes a parametric conditional probability distribution, where the parameters are given by the connection weights. Information Geometry studies the geometry of statistical models with tools from differential and Riemannian geometry. Not surprisingly, one of the first applications of Information Geometry was related to the training of neural networks using the natural gradient. Neural networks were quite promising in the 80s in the machine learning community, but later on other methods gradually became more popular. More recently, starting from 2011-12, neural networks and their use in deep learning architectures have become prominent, thanks to their state-of-the-art performance in several different fields. In this talk we review the geometry of neural networks from the perspective of Information Geometry after almost 20 years from its conception, and we present some more recent applications of natural gradient-based methods for the training of deep neural networks. ore 14:00 Giovanni Pistone, ', de Castro Statistics, Collegio Carlo Alberto, Moncalieri TITLE: Geometries of the Gaussian Model ABSTRACT: In Information geometry, it is possible to define a number of different geometrical structures on the full Gaussian model: the Fisher-Rao Riemannian Manifold (S.T. Skovgaard 1981), the Wasserstein Riemannian Manifold (A. Takatsu 2011), the Exponential and Mixture Affine manifolds (G. Pistone & C. Sempi 1995). We discuss the features of these geometries, including the second order properties (e.g. Hessians), with special emphasis of the Wasserstein case. This turns out to be a special case of a more general set-up introduced in 2001 by R. Otto. Applications, due to L. Malagò (in progress), are presented. ————————————————————————————— Prof. Eva Riccomagno Dipartimento di Matematica - Universita` degli Studi di Genova Via Dodecaneso, 35 - 16146 Genova - ITALIA Tel: +39 - 010 - 353 6938 Fax: +39 - 010 - 353 6960 www.dima.unige.it/~riccomag

Like in the past four years, the 2017 school will be held in the magnificent Villa del Grumello, in Como (Italy), on the Lake Como shore. Raffaele Argiento ABS17 Executive Director Guido Consonni and Fabrizio Ruggeri ABS17 Directors ------------------------------------------------------------------------ ******************************* * ABS17 * ******************************* Applied Bayesian Statistics School MODELING SPATIAL AND SPATIO-TEMPORAL DATA WITH ENVIRONMENTAL APPLICATIONS June 19-23, 2017 Villa del Grumello, Como, Italy Lecturer: Bruno Sanso', Professor of Statistics, University of California Santa Cruz https://users.soe.ucsc.edu/~bruno/ The conference webpage is >>>> web.mi.imati.cnr.it/conferences/abs17.html <<<< Registration is now open. Please note that the conference room allows only for a limited number of participants. The ABS17 Secretariat can be contacted at abs17(a)mi.imati.cnr.it COURSE OUTLINE This course is intended for students who have a background in statistical methods and modeling. The course is focused on models for data that are spatially referenced and that evolve in time. We will develop models for stochastic processes that are indexed at irregularly scattered, fixed, locations. We will look into the theoretical properties of those models as well as into the computational issues involved in the estimation of their parameters. We will extend the analysis of fields of spatial observations that are collected in time. In particular, we will consider dynamically varying process where space and time interact. Real-data applications of Bayesian methods with MCMC techniques will be illustrated. Day 1: Introduction to Bayesian methods and hierarchical models. Examples of spatially referenced data. Basic properties of Gaussian random fields. Graphical exploration of spatial fields. Day 2: Variograms. Examples of families of correlations functions. Bayesian approach to estimation and prediction of spatial random fields. Day 3: The big data problem: reduced rank models and other modern approaches to dimension reduction. Day 4: Spatio-temporal models. Dynamic linear models: integro-differential equations. Day 5: Extensions 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. -- Dr. Raffaele Argiento University of Torino and Collegio Carlo Alberto www.raffaeleargiento.it

Avviso di seminari Prof. Eva LÖCHERBACH
by Enrica Pirozzi 07 Dec '16

Prof. Eva LÖCHERBACH Département de Mathématiques Faculté des Sciences et Techniques Université de Cergy-Pontoise TITLE: Modeling spike trains by systems of interacting Hawkes processes with (or without) memory of variable length Tuesday, December 13 at 15:30 Part I Wednesday, December 14 at 15:00 Part II Friday, December 16 at 11:00 Part III at Dipartimento Matematica e Applicazioni, Università di Napoli FEDERICO II, Complesso di Monte Sant'Angelo, Via Cintia, Napoli. ABSTRACT: Let us consider a class of non Markovian processes with a countable number of interacting components, both in discrete and continuous time. Each component is represented by a point process indicating if this component has a spike or not at a given time. The system evolves as follows. For each component, the rate (in continuous time) or the probability (in discrete time) of having a spike depends on the entire time evolution of the system since the last spike time of the component. In discrete time this class of systems extends in a non trivial way both Spitzer's interacting particle systems, which are Markovian, and Rissanen's stochastic chains with memory of variable length which have finite state space. In continuous time they can be seen as a kind of Rissanen's variable length memory version of the class of self-exciting point processes which are also called ``Hawkes processes'', however with infinitely many components. These features make this class a good candidate to describe the time evolution of networks of spiking neurons. In the lectures, I will present the model, both in discrete and in continuous time. I will then sketch results concerning perfect simulation and existence issues, de-correlation between successive interspike intervals, the longtime behavior of finite systems and propagation of chaos in mean field systems. ------ -- Enrica Pirozzi Dipartimento di Matematica e Applicazioni Universita' di Napoli FEDERICO II Via Cintia, Monte S.Angelo, 80126, NAPOLI, ITALY Tel. 081 675634 https://www.docenti.unina.it/ENRICA.PIROZZI

Seminario RAO
by Matteo Ruggiero 07 Dec '16

07 Dec '16

************************************************************************ STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO ************************************************************************ Mercoledì 14 Dicembre 2016 alle ore 12:00, presso l’Aula Rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: Vinayak RAO (Purdue University) PATH AND PARAMETER INFERENCE FOR MARKOV JUMP PROCESSES A variety of phenomena are best described using dynamical models which operate on a discrete state-space and in continuous time. The most common example is the Markov jump processes whose applications range from systems biology, genetics, computing networks and human-computer interactions. Posterior computations typically involve approximations like time discretization and can be computationally intensive. In the first half of this talk, I will describe some previous work (joint with Yee Whye Teh) on a class of Markov chain Monte Carlo methods that allow efficient computations while still being exact. The core idea builds on the idea of 'uniformization', and is an auxiliary variable Gibbs sampler that alternately resamples a random discretization of time given the state-trajectory of the system, and then samples a new trajectory given this discretization. In the second half, I will talk about more recent work (joint with Boqian Zhang) that extends these ideas to allow efficient Bayesian inference over the process parameters. Here we reformulate the earlier idea to develop an efficient Metropolis-Hastings algorithm that more naturally exploits the symmetry of the problem. In our experiments, we show improved performance over the current state of the art. Tutti gli interessati sono invitati a partecipare. Il seminario e' organizzato dalla "de Castro" Statistics Initiative (http://www.carloalberto.org/stats <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 <http://www.matteoruggiero.it/>
