Recommandation et analyse de sentiments dans un espace latent textuel

Recommender systems were developed to cherry-pick interesting content in an always growing environment to help users discover new products or information that they might like. Traditional collaborative filtering methods mainly focus on the ratings to establish user profiles, ignoring the joint review text. Our work does the opposite. We use the written comments as the primary source of informat...

Partage d'autorité dans un essaim de drones auto-organisé

This paper addresses the human control of a large number of unmanned air vehicles (UAVs) for the surveillance of a sensitive outdoor area. We leverage the combination of sensor network and environment marking for swarm intelligence. This grants autonomy to the UAVs system and allows the operator to focus on noteworthy tasks like counter-intrusion. This paper presents the experimental results of...

Complexité en espace de l'exploration de graphes

Graph Exploration is a problem motivated by several aspects of theoretical computer science, including logic and computational complexity. It has also numerous applications in robotics. In all these contexts, the amount of memory used by the mobile entity (robot, finite automaton, etc.) performing exploration is a key parameter. In this thesis, we study in depth the space complexity of graph ex...
