Functional inequalities, flows, symmetry and spectral estimates

Event Date: Dec 07, 2018 in CMM Modeling, Seminars

ABSTRACT:   In this talk I will review recent result about how the use of linear and nonlinear flows has been key to prove functional inequalities and qualitative properties for their extremal functions. I will also explain how from these inequalities and their best constants, optimal spectral estimates can be obtained for Schrödinger operators. This is a topic which is at the crossroads of nonlinear analysis and probability, with implications in differential geometry and potential applications in modelling in physics and...

Particles-based simulations and GPU computing for soft matter science and computer graphics applications

Event Date: Oct 25, 2018 in CMM Modeling, Seminars

Summary:   Particle-based simulation codes used in soft matter science aim at represent the interactions that occur in colloidal suspensions at nanoscale level. These suspensions are a mixture of solid particles of diameter between 100 and 1000 nanometers and a solvent (usually water), all interacting with each other. The main goal when implementing these codes on the GPU is to accelerate the “particle neighbour searching” phase, which is the bottleneck in most lagrangian-based simulations. I will present recent results obtained for Brownian Dynamics, where the solvent is...

“Deep Variational Transfer: Transfer Learning through Semi-supervised Deep Generative Models”

Event Date: Jun 14, 2018 in CMM Modeling, Seminars

Abstract: “In real-world applications, it is expensive and time-consuming to obtain labeled examples. In such cases, knowledge transfer from related domains, where labels are abundant, could greatly reduce the need for extensive labeling efforts. In this scenario, transfer and multi-task learning come in hand. In this paper, we propose Deep Variational Transfer (DVT), a variational autoencoder that transfers knowledge across domains using a shared latent Gaussian mixture model. More in details, we align all supervised examples of the same class into the same Gaussian Mixture component,...

“A brief introduction to Mean Field Games”

Event Date: Jan 19, 2015 in CMM Modeling, Seminars

Abstract: Mean Field Games (MFG) is a theory recently introduced by J.-M. Lasry and P.-L. Lions in order to approximate Nash equilibria of symmetric stochastic differential games when the number of players is very large. This theory has found several applications in mathematical economics and congestion models. The aim of this course is to introduce the theory from the very basics. In the three lectures we will address the following topics: Lecture 1: The case of static games. In this lecture we will discuss the  relation between games with a finite number of players and mean field games in...
