Séminaire de Andrea Simonetto

19/01/2021 – 14h00-15h00 – Online Personalized optimization for cyber-physical and social systems Andrea Simonetto (IBM Research Ireland) Abstract. Optimization is the cornerstone of many engineering systems and cyber-physical systems including smart homes, energy grids, and intelligent transportation systems. In many situations however, state-of-the-art optimization algorithms may fail to provide acceptable (and feasible) solutions e.g. because […]

Efficient MCMC sampling via asymptotically exact data augmentation

Speaker — Maxime Vono (IRIT — INP-ENSEEIHT) https://s3-seminar.github.io/seminars/maxime-vono/ Abstract — Performing exact Bayesian inference for complex models is computationally intractable. Markov chain Monte Carlo (MCMC) algorithms can provide reliable approximations of the posterior distribution but are expensive for large datasets and high-dimensional models. A standard approach to mitigate this complexity consists in using subsampling techniques […]

Séminaire de Guilherme Mazanti

08/12/2020 – 14h00-15h00 – Online The multiplicity-induced-dominancy property for scalar differential equations with time-delays Guilherme Mazanti (INRIA équipe DISCO, L2S, CentraleSupélec) Abstract. Even in simple situations with time-delays such as that of linear equations with constant coefficients and constant delays, the spectral analysis of time-delay systems can be a challenging question. Indeed, contrarily to the […]

Fast fault identification in meshed HVDC grids: a fault parameter estimation approach (Paul Verrax)

Paul Verrax, PhD student at L2S and SuperGrid Institute. Tuesday 8th December at 11:00 via Microsoft Teams at Join Microsoft Teams MeetingLearn more about Teams Abstract: The emergence of meshed HVDC grids is seen as a promising option to interconnect large amount of renewable energies over long distances.  The protection of such grids requires the fast […]
