In this article, we present an on-line variational Bayes (VB) method for the identification of linear state space models. The learning algorithm is implemented as alternate maximization of an on-line free energy, which can be used for determining the dimension of the internal state. We also propose a reinforcement learning (RL) method using this system identification method. Our RL method is applied to a simple automatic control problem. The result shows that our method is able to determine correctly the dimension of the internal state and to acquire a good control, even in a partially observable environment.
