Adaptive bases for Q-learning
Abstract-- We consider reinforcement learning, and in particular, the Q-learning algorithm in large state and action spaces. In order to cope with the size of the spaces, a function approximation approach to the state and action value function is needed. We generalize the classical Q-learning algorithm to an algorithm where the basis of the linear function approximation change dynamically while interacting with the environment. A motivation for such an approach is maximizing the state-action value function fitness to the problem faced, thus obtaining better performance. The algorithm is shown to converge using two time scales stochastic approximation. Finally, we discuss how this technique can be applied to a rich family of RL algorithms with linear function approximation.
