11 Apr '19

Luned' 15 Aprile avremo il seguente seminario in Aula di Consiglio (Dipartimento di Matematica, La Sapienza, Roma), alle ore 16.00: Speaker: Marco Romito (Universita' di Pisa). Title: Fluctuations for point vortices Abstract: The first part of the presentation is a short review of a statistical mechanics model of point vortices for the 2D Euler equations and their mean field limit. In the second part we outline a proof of Gaussian fluctuations from the mean field limit. The result holds on the torus, on the sphere and on bounded domains. This is a work in collaboration with Francesco Grotto (Scuola Normale Superiore, Pisa). saluti 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 *************************************************

Dear Colleagues, a special session entitled ‘Challenges in modelling sparse and noisy data’ will take place during the AMASES Annual Conference, which will be held in Perugia on September 9-11, 2019 (http://amases2019.unipg.it<http://amases2019.unipg.it/>). [http://amases2019.unipg.it/images/piazza4novembre.jpg]<http://amases2019.unipg.it/> AMASES 2019<http://amases2019.unipg.it/> amases2019.unipg.it 43 rd Annual Meeting of the AMASES Association for Mathematics Applied to Social and Economic Sciences Perugia, September 9-11, 2019. The meeting is organized both by the Department of Mathematics and Computer Science and the Department of Economics of the University of Perugia. As in the AMASES established tradition, the purpose of the meeting is to stimulate discussion among scholars and ... Topic of the session Far more than in the past, policy makers, investors, and data scientists are required to take decisions based on sparse and noisy data. Observations from heterogeneous sources, typically sampled at different frequencies, and contaminated by noise, need to be aggregated and analyzed jointly. This is customary in several economic applications, including macroeconomics, high-frequency finance, climate economics, and data science. Traditional mathematical and statistical methods can lead to misleading conclusions when these features are not properly accounted for. The objective of this session is to present the latest methodologies and to foster discussions among researchers from different fields. Theoretical and empirical papers are welcome. Topics include but are not limited to: - high-frequency time series modelling - mixed-frequency data modelling in economic and social sciences - dimensionality reduction and factor analysis - sparse data modelling - noisy data filtering and smoothing It is a great pleasure to invite you to submit an extended abstract. To be considered for the stream, please submit your abstract by specifying the stream code (MSND) in the file name (MSND-[surname of author who will present the paper].pdf). Please refer to the official web page of the conference for further details on the submission. Important dates: May 1, 2019: deadline for abstract submission June 10, 2019: notification of acceptance June 17, 2019: early registration July 1, 2019: late registration For information, please contact: Giacomo Bormetti (giacomo.bormetti(a)unibo.it) Giuseppe Buccheri (giuseppe.buccheri(a)sns.it) Fabrizio Lillo (fabrizio.lillo(a)unibo.it) We are looking forward to meeting you in Perugia.

Seminario PAULIN

05 Apr '19

STATISTICS SEMINARS @ COLLEGIO CARLO ALBERTO Venerdì 12 Aprile 2019, alle ore 12:00, presso il nuovo edificio del Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terrà il seguente seminario: ------------------------------------------------ Daniel PAULIN (University of Oxford) CONNECTIONS BETWEEN OPTIMIZATION AND SAMPLING In this talk, I am going to look at some connections between optimization and sampling. In “Hamiltonian descent methods’’, we introduce a new optimization method is based on conformal Hamiltonian dynamics. It was inspired by the literature on Hamiltonian MCMC methods. The use of general kinetic energies allows us to obtain linear rates of convergence for a much larger class than strongly convex and smooth functions. “Dual Space Preconditioning for Gradient Descent” applies a similar idea to gradient descent. We introduce a new optimization method based on nonlinear preconditioning of gradient descent, with simple and transparent conditions for convergence. “Randomized Hamiltonian Monte Carlo as Scaling Limit of the Bouncy Particle Sampler and Dimension-Free Convergence Rates” studies the high dimensional behaviour of the Bouncy Particle Sampler (BPS), a non-reversible piecewise deterministic MCMC method. Although the paths of this method are straight lines, we show that in high dimensions they converge to a Randomised Hamiltonian Monte Carlo (RHMC) process, whose paths are determined by the Hamiltonian dynamics. We also give a characterization of the mixing rate of the RHMC process for log-concave target distributions that can be used to tune the parameters of BPS. ------------------------------------------------ Tutti gli interessati sono invitati a partecipare. Il seminario è organizzato dalla "de Castro" Statistics Initiative (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
