Seminario di Probabilità - Padova
by Paolo Dai Pra 15 Jun '16

15 Jun '16

Ho il piacere di invitarvi al seguente seminario, che si terrà Giovedì 23 Giugno, alle 15:00, in aula 2AB40 della Torre Archimede presso il Dipartimento di Matematica dell'Università degli Studi di Padova. SPEAKER: Paolo Pigato AFFILIATION: INRIA Nancy-Grand Est TITLE: Statistical estimation of diffusion processes with discontinuous coefficients ABSTRACT: We consider the problem of estimating the parameters of the Oscillating Brownian Motion, a classical example of stochastic differential equation with discontinuous diffusion coefficient. We see how to construct this process as limit of Oscillating Random Walks, and consider the problem of statistical estimation of these discrete objects. We then study the convergence of some estimators for the parameters of the limiting process.

Seminario SCOTT

******************************************************************* STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO ******************************************************************* Mercoledi 22 Giugno 2016 alle ore 12:00, presso l’Aula Rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: Steven SCOTT (Google) PREDICTING THE PRESENT WITH BAYESIAN STRUCTURAL TIME SERIES This article describes a system for short term forecasting based on an ensemble prediction that averages over different combinations of predictors. The system combines a structural time series model for the target series with regression component capturing the contributions of contemporaneous search query data. A spike-and-slab prior on the regression coefficients induces sparsity, dramatically reducing the size of the regression problem. Our system averages over potential contributions from a very large set of models and gives easily digested reports of which coefficients are likely to be important. We illustrate with applications to initial claims for unemployment benefits and to retail sales. Although our exposition focuses on using search engine data to forecast economic time series, the underlying statistical methods can be applied to more general short term forecasting with large numbers of contemporaneous predictors. 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.

Politecnico di Milano - Seminario L. Calatroni

Si avvisa che in data 11/07/2016, alle ore 11:30 precise, presso Aula Seminari "Saleri" VI Piano, Dipartimento di Matematica, Politecnico di Milano, nell'ambito delle iniziative MOX, si svolgerà il seguente seminario: Relatore: Luca Calatroni, Experienced Researcher Marie-Curie fellow, Camelot Biomedical systems, Genova and MIDA group, Università degli studi di Genova Titolo: Design and optimisation of non-smooth Imaging models via Partial Differential Equations Abstract: Variational methods and Partial Differential Equations (PDEs) have been extensively employed for the mathematical formulation of a myriad of problems describing physical phenomena such as heat propagation, thermodynamic transformations and many more. In imaging, PDEs following variational principles are often considered. In their general form these models combine a regularisation and a data fitting term, balancing one against the other appropriately. Typically, Total variation (TV) regularisation is used due to its edge-preserving and smoothing properties. In this talk, we focus on the use of PDEs for the optimal design of several Imaging models. Starting from the use of higher-order and non-smooth variants of classical heat-type diffusion models often employed to counteract well-known TV reconstruction drawbacks (such as staircasing), we focus in particular on the use of non-smooth optimisation approaches with PDE constraints in the context of optimal parameter estimation for some non-standard image denoising problems. Finally, we consider some TV-based models recently reinterpreted in the framework of graphs and applied to some image segmentation problems. Tutti gli interessati sono invitati a partecipare.

******************************************************************* STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO ******************************************************************* Lunedi 20 Giugno 2016 alle ore 12:00, presso l’Aula Rossa del Collegio Carlo Alberto, Moncalieri (TO), si terra' il seguente seminario: Natesh PILLAI (Harvard University) BAYESIAN FACTOR MODELS IN HIGH DIMENSIONS Sparse Bayesian factor models are routinely implemented for parsimonious dependence modeling and dimensionality reduction in high-dimensional applications. We provide theoretical understanding of such Bayesian procedures in terms of posterior convergence rates in inferring high-dimensional covariance matrices where the dimension can be larger than the sample size. We will also discuss other high dimensional shrinkage priors and discuss them in the context of factor models. Tutti gli interessati sono invitati a partecipare.

Seminario Marina Santacroce
by Marco Maggis 08 Jun '16

08 Jun '16

Con preghiera di diffusione ai possibili interessati. Annuncio di Seminario, Martedì 21 Giugno, ore 12:30, Sala di Rappresentanza Dipartimento di Matematica (UniMi) Via C. Saldini 50 Milano Professoressa Marina Santacroce, Dipartimento di Matematica, Politecnico di Torino Title: From classical to general utilities maximization: control techniques versus other approaches. Abstract: In this talk we discuss methods which give constructive characterizations of the optimal strategies for expected utility maximization problems in a continuous semimartingale setting. In particular, we focus on a method which seems to provide a valid alternative to dynamic programming and works for general utilities and, besides, displays a clear link with convex duality.
