Simone Scotti seminar [ Comp.Science Dept. UniVr ; January 11, 2017 - 3:00 PM ]
by Luca di persio 28 Dec '16

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

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.

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

************************************************************************ 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.

PhD course on "Rough Paths and Stochastic Differential Equations"
by Francesco Caravenna 06 Dec '16

06 Dec '16

This email is to announce a Ph.D. course on "Rough Paths and Stochastic Differential Equations" in the framework of the Pavia - Milano Bicocca - Indam PhD program in Mathematics. The course is devoted to students interested in analysis and/or probability (see below for the abstract). The course will last 30 hours and will be given in the period February-March 2017 at the University of Milano-Bicocca. In order to fix the precise dates, we kindly ask all interested people to contact us by Tuesday 13 December 2016 and let us know of their engagements in that period. Best regards, Francesco Caravenna and Gianmario Tessitore %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Title: Rough Paths and Stochastic Differential Equations Place: University of Milano-Bicocca Period: February-March 2017 Prerequisites: A basic knowledge of Holder functions and Brownian motion. Abstract: This course is an introduction to rough paths, a modern theory which provides an analytic counterpart to the probabilistic theory of stochastic integration. Rough paths allow to define a notion of integral with respect to the derivative of a Holder function, generalizing the usual Riemann-Steltjes integral. A key motivation of rough paths is to shed new light on the stochastic integration with respect to Brownian motion and on the corresponding stochastic differential equations. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% _________________________________________ Francesco Caravenna Dipartimento di Matematica e Applicazioni Università degli Studi di Milano-Bicocca Via Cozzi 55, 20125 Milano, Italy http://www.matapp.unimib.it/~fcaraven/ _________________________________________

Il Prof. A. Smith dell'universita' di Ottawa terra' tre lezioni nell'ambito del dottorato in matematica presso il Dip. di Matematica e Fisica di Roma Tre con il seguente programma: *MIXING OF MARKOV CHAINS ON MANIFOLDS* Martedi 6 Dicembre ore 11:00-13:00 aula 311 *Mixing Properties of Hamiltonian Monte Carlo* Abstract:* Hamiltonian Monte Carlo (HMC) and its variants are extremely popular Markov chain Monte Carlo algorithms in statistical computing. In practice, they seem to outperform classical algorithms such as the Gibbs sampler and the Metropolis-Hastings algorithm. Unfortunately, the characteristic long moves made by HMC also make it difficult to analyze. I will survey some existing results on HMC and competitor algorithms, including some recent results of myself and Mangoubi, and present open problems.* Mercoledi 7 Dicembre ore 14:30-16:30 aula 311 *Convex Sets, Conductance and Curvature.* Abstract: Geometric random walks are popular tools for sampling from the interior or boundary of convex sets. I will introduce some popular geometric random walks and describe the mathematical techniques developed by Dieker, Kannan, Lovasz, Vempala and others to analyze them. I will then describe how some recent work takes advantage of ideas from geometry and convex optimization to propose and analyze algorithms that can have improved performance. Martedi 13 Dicembre ore 11:00-13:00 aula 311 *Kac's Walks and Couplings.* Abstract: Kac's walks on the sphere and on the special orthogonal group. introduced in 1953 and 1970, have long histories in the statistical physics and computational statistics literatures. I will describe the history of these walks and review some of the many results on the mixing properties of these processes. I then present some recent work of myself and Pillai, which uses connections to random matrix theory to obtain substantially improved bounds on the mixing times of these two walks. -- Fabio Martinelli Department of Mathematics and Physics Roma Tre University Lg.

********************************************************************* SEMINARI DI PROBABILITA' E STATISTICA MATEMATICA DIPARTIMENTO DI MATEMATICA "G. PEANO" UNIVERSITA' DEGLI STUDI DI TORINO ********************************************************************* Martedì 6 dicembre alle ore 12:00 in aula C presso il Dipartimento di Matematica "G. Peano" dell'Università degli Studi di Torino, Via Carlo Alberto 10, Il Prof. SAMUEL HERRMANN (Université de Bourgogne) terrà un seminario dal titolo Initial-Boundary Value Problem for the heat equation - A stochastic algorithm Abstract: The Initial-Boundary Value Problem for the heat equation is solved using a new algorithm based on a random walk on heat balls. Even if it represents a sophisticated generalisation of the Walk on Spheres (WoS) algorithm introduced to solve the Dirichlet problem for Laplace's equation, its implementation is rather easy. The definition of the random walk is based on a new mean value formula for the heat equation. The convergence results and different numerical examples permit to emphasize the efficiency and accuracy of the algorithm. Tutti gli interessati sono invitati a partecipare. -- Dr. Cristina Zucca Department of Mathematics University of Torino Via Carlo Alberto 10 10123 Torino, Italy tel: +39-011-6702850 fax: +39-011-6702878
