Biography

I am a PhD student in Machine Learning at Ecole Normale Supérieure in the Inria VALDA team. I am lucky to be supervised by Olivier Cappé and Aurélien Garivier. My research interests include sequential learning with partial information feedback and more precisely bandits models. The main objective of my research is to improve decision-making in uncertain and dynamic environments. In particular, I have worked on passively forgetting strategies that are well-suited for non-stationary environments.
