In the context of team Cornet’s seminars, Olivier Bilenne (LIA) will present his research work on Implementing fictitious play in partially observable stochastic games, on November 24, 2023, 11:35 in the meeting room. Abstract: Extensions of fictitious play to stochastic games have been recently examined in combination with reinforcement learning techniques inherent to Markov decision processes. We revisit this approach in the context of partially observable stochastic games. For this, we consider a two-player (finite-state) zero-sum stochastic game where one player (the attacker) has full visibility of the system, whereas the other player (the defender) has no access to the state of the opponent and must instead compose with public sources of information (in our setting: the actions played and their associated payoffs). We study a fictitious play dynamics where the players best response to the estimated empirical frequencies of action of their opponent. This sequence of play requires from the players to form beliefs on both their opponent’s strategy and on their own continuation payoff (modeled by a Q-function), based on the (full or partial) information that is available to them. The strategy estimation scheme, in particular, features a correction mechanism making up for delayed symptoms in the partially Plus d'infos

In the context of team Cornet’s seminars, Willie Kouam (LIA) will present his research work on Asymmetric Centrality Game against Network Epidemic Propagation, on September 29, 2023, at 11:35 in the meeting room.

In the context of team Cornet’s seminars, Wesley Coelho (Pasqal) will present his research work on Solving optimization problems with PASQAL quantum computers, on September 14, 2023, at 11:35 in the meeting room. Abstract: The emergence of quantum devices opens many exciting perspectives in the high-performance computing world. Among other quantum platforms, fully programmable neutral atom devices display unique characteristics and, by better controlling quantum entanglement and superposition, they represent a powerful tool to tackle complex problems and computing challenges. In this talk, Clément de Terrasson and Wesley Coelho will show how PASQAL Quantum Computers are used to address complex optimization problems. They will also propose a workshop where participants will be able to use PASQAL solutions to solve optimization problems.

In the context of team Cornet’s seminars, Éric Bourreau (LIRMM) will present his research work on Quantum Computers, a New Information Technology Revolution?, on June 23, 2023, at 11:35 in the meeting room. Abstract: The concept of quantum computing dates back to the late 1980s, and the first quantum algorithms were born in the 1990s. However, the novelty of recent years is the construction of actual quantum machines that are beginning to validate the theory. This seminar will attempt to explain how the definition of QuBits (quantum bits) gives rise to a new paradigm of computation. We will try to understand what computational power is now being offered and at what point quantum optimization could become competitive with ‘classical’ optimization methods.
