Seminario Lionel Levine (Cornell), Università La Sapienza
by Silvestri, Vittoria 16 Dec '19

16 Dec '19

PREANNUNCIO DI SEMINARIO (seguirà un reminder) Seminario di Probabilità Speaker: Lionel Levine (Cornell University) Title: Random walks with local memory Martedì 7 Gennaio, ore 14:00 (sharp) Aula di Consiglio Dipartimento di Matematica Università di Roma La Sapienza Piazzale Aldo Moro, 5 Abstract: The theme of this talk is walks in a random environment of "signposts" altered by the walker. I'll focus on three related examples: 1. Rotor walk on Z^2. Your initial signposts are independent with the uniform distribution on {North,East,South,West}. At each step you rotate the signpost at your current location clockwise 90 degrees and then follow it to a nearest neighbor. Priezzhev et al. conjectured that in n such steps you will visit order n^{2/3} distinct sites. I'll outline an elementary proof of a lower bound of this order. The upper bound, which is still open, is related to a famous question about the path of a light ray in a grid of randomly oriented mirrors. This part is joint work with Laura Florescu and Yuval Peres. 2. p-rotor walk on Z. In this walk you flip the signpost at your current location with probability 1-p and then follow it. I'll explain why your scaling limit will be a Brownian motion perturbed at its extrema. This part is joint work with Wilfried Huss and Ecaterina Sava-Huss. 3. p-rotor walk on Z^2. Rotate the signpost at your current location clockwise with probability p and counterclockwise with probability 1-p, and then follow it. This walk “organizes” its environment by destroying cycles of signposts. A native environment -- stationary in time, from your perspective as the walker -- is an orientation of the uniform spanning forest, plus one additional edge. This part is joint work with Swee Hong Chan, Lila Greco, and Peter Li: https://arxiv.org/abs/1809.04710 ******************************** Vittoria Silvestri Assistant Professor Department of Mathematics University "La Sapienza" Piazzale Aldo Moro, 5 00185 - Rome ********************************

Seminar at Scuola Normale Superiore, 17 December 2019, Luciano Campi
by Giulia Livieri 13 Dec '19

13 Dec '19

Dear all, On Tuesday, 17 December 2019 — at 11:30 — at the Scuola Normale Superiore (Room: Aula Bianchi Scienze) Prof. Luciano Campi (London School of Economics) will hold the following Seminar: Title : Correlated Equilibria and Mean Field Game Abstract: Mean field games are limit models for symmetric N-player games, as N tends to infinity, where the pre-limit models are solved in terms of Nash equilibria. A generalization of the notion of Nash equilibrium, due to Robert Aumann (1973, 1987), is that of a correlated equilibrium. Here, we discuss, in a simple non-static setting, the mean field game limit for correlated equilibria. We give a definition of correlated mean field game solution, prove that it arises as limit of N-player correlated equilibria in restricted (”open-loop”) Markov feedback strategies, and show how to construct approximate N-player equilibria starting from a correlated mean field game solution. We also compare our definition to the one by Lacker (2018) of weak solutions for mean field games without a common noise. (Joint work with Markus Fischer, Padova University) Fill free to forward this announcement to your colleagues.

Doppio Seminario PELUCHETTI & KOWAL
by Pierpaolo De Blasi 13 Dec '19

13 Dec '19

Mercoledi 18 Dicembre 2019, presso il nuovo edificio del Collegio Carlo Alberto, in Piazza Arbarello 8, Torino, si terranno i seguenti due seminari: ———————————————————————— ore 11.00 Stefano PELUCHETTI (Cogent Labs Tokyo) DEEP NEURAL NETWORKS AND STOCHASTIC PROCESSES We review deep neural networks and their training, and then focus on the connection between neural networks and stochastic processes. Deep neural networks at initialization correspond to prior models in function space, and under appropriate assumptions they converge to Gaussian processes in the limit of infinite width. While this connection holds "a priori", it is possible to derive similar results for "a posteriori" training via gradient descent. In this talk we discuss these and related results, and we introduce a recent line of research which generalizes established results to non-Gaussian initializations and stochastic processes arising in the limit of infinite depth. ———————————————————————— ore 12.00 Daniel KOWAL (Rice University) SCALABLE BAYESIAN INFERENCE AND SUMMARIZATION FOR FUNCYIONAL DATA Modern scientific monitoring systems, such as wearable and implantable devices, commonly record data over a continuous domain at high resolutions. These functional data are high-dimensional, strongly correlated, and usually measured concurrently with other variables of interest. Bayesians models for functional data are particularly appealing: they accommodate multiple dependence structures, handle missing or irregularly-spaced data, and provide regularization via shrinkage priors. However, these models are often complex, computationally intensive, and difficult to interpret. This talk will focus on two fundamental challenges for Bayesian functional data analysis: (1) constructing sufficiently flexible and scalable functional regression models and (2) extracting interpretable posterior summaries. The proposed modeling framework is nonparametric and uses an unknown functional basis to learn prominent functional features, which are associated with scalar predictors within a regression model. A customized projection-based Gibbs sampler provides posterior inference with linear time complexity in the number of predictors, which is empirically faster than existing frequentist and Bayesian alternatives. Using the posterior distribution, a decision theoretic approach for Bayesian variable selection is developed, which identifies a subset of covariates that retains nearly the predictive accuracy of the full model. The methodology is applied to actigraphy data to investigate the association between intraday physical activity and responses to a sleep questionnaire. ———————————————————————— Tutti gli interessati sono invitati a partecipare. Il seminario è organizzato dalla "de Castro" Statistics Initiative (www.carloalberto.org/stats <http://www.carloalberto.org/stats>) in collaborazione con il Collegio Carlo Alberto.
