Abstract：Average reward reinforcement learning is an important undiscounted optimality framework. However, most of the work was based on discrete state space tasks. In this paper, how to combine function approximation with average reward learning is studied, and the parameter update condition is modified according to the continuous space. Besides, a close study on the performance of G-learning and its insensitivity to learning parameters is made. Finally, experimental results and relevant analysis are presented. The experimental results validate the solutions of R-learning and G-learning are prone to diverge when ε is relatively small. And the results also show that the Tile Coding is effective in function approximation as a feature extraction method and it can be taken as a comparative standard for other methods.
