Abstract : This thesis studies the automatic acquisition by machine learning of a context model for a user in a ubiquitous environment. In such an environment, devices can communicate and cooperate in order to create a consistent computerized space. Some devices possess perceptual capabilities. The environment uses them to detect the user's situation - his context. Other devices are able to execute actions. Our problematics consists in determining the optimal associations, for a given user, between situations and actions. Machine learning seems to be a sound approach since it results in a customized environment without requiring an explicit specification from the user. A life long learning lets the environment adapt itself continuously to world changes and user preferences changes. Reinforcement learning can be a solution to this problem, as long as it is adapted to some particular constraints due to our application setting.
