Yoan Russac

PhD Student in Machine Learning

Ecole Normale Supérieure


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.
