Résumé HAL : Lilian Besson

I am Lilian Besson, a former student in Mathematics and Computer Science at ENS de Cachan. I am a passionnate programmer, open-source enthusiast and young researcher in machine learning, learning theory and cognitive radio.

From August 2019, I am now a junior professor (agrégé) at ENS Rennes, in charge of the class preparing the "agrégation" national exam, with a major in mathematics and a minor in computer science, level M2, and in charge of lectures for introduction and advanced algorithms.

I am also an associate researcher with the PANAMA team at IRISA and INRIA Rennes. My research interests lie between sequential learning, tensor decomposition, cognitive radio, Python and open source software, and other directions.

Between september 2016 and fall 2019 :

  • I was pursuing my PhD at CentraleSupélec (SCEE team, IETR lab) in Rennes (France), with Christophe Moy and Emilie Kaufmann (Inria, SequeL team, CRIStAL lab, at Lille). My PhD is on multi-players multi-arms bandits models applied to radio-telecommunication, especially Internet-of-Things problems. I defended in November, and I now hold a PhD in telecommunications.
  • And I have been teaching 64 hours by year, in theoretical computer science at ENS Rennes (for a class preparing for the "agrégation" national exam, with a major in mathematics and a minor in computer science, level M2), at ENSAI (complexity and calculabilty, level L3).
