基于两层模糊划分的时间差分算法
TD algorithm based on double-layer fuzzy partitioning
摘要
Abstract
When dealing with the continuous space problems, the traditional Q-iteration algorithms based on lookup-table or function approximation converge slowly and are difficult to get a continuous policy. To overcome the above weak-nesses, an on-policy TD algorithm named DFP-OPTD was proposed based on double-layer fuzzy partitioning and its convergence was proved. The first layer of fuzzy partitioning was applied for state space, the second layer of fuzzy parti-tioning was applied for action space, and Q-value functions were computed by the combination of the two layer fuzzy partitioning. Based on the Q-value function, the consequent parameters of fuzzy rules were updated by gradient descent method. Applying DFP-OPTD on two classical reinforcement learning problems, experimental results show that the algo-rithm not only can be used to get a continuous action policy, but also has a better convergence performance.关键词
