Abstract : This thesis studies the use of connectionist algorithms for solving reinforcement learning problems. Connectionist algorithms are inspired by the way information is processed by the brain: they rely on a large network of highly interconnected simple units, which process numerical information in a distributed and massively parallel way. Reinforcement learning is a computational theory that describes the interaction between an agent and an environment: it enables to precisely formalize goal-directed learning from interaction.

We have considered three problems, with increasing complexity, and shown that they can be solved with connectionist algorithms: 1) Reinforcement learning in a small state space: we exploit a well-known algorithm in order to build a connectionist network: the problem's paramaters are stored into weighted units and connections and the planning is the result of a distributed activity in the network. 2) Learning a representation for approximating a reinforcement learning problem with a large state space: we provide an algorithm for automatically building a state space partition in order to approximate a large problem. 3) Self-organization of specialized modules for approximating various reinforcement problems with a large state space: we exploit a divide and conquer'' approach and show that various tasks can efficiently be spread over a little number of specialized functional modules.
