Current recommender systems need to recommend items that are relevant to users (exploitation), but they must also be able to continuously obtain new information about items and users (exploration). This is the exploration / exploitation dilemma. Such an environment is part of what is called "reinforcement learning". In the statistical literature, bandit strategies are known to provide solutions to this dilemma. The contributions of this multidisciplinary thesis the adaptation of these strategies to deal with some problems of the recommendation systems, such as the recommendation of several items simultaneously, taking into account the aging of the popularity of an items or the recommendation in real time.Les systèmes de recommandation actue...
