原始语种摘要: Abstract(#br)Categorical Distributional Reinforcement Learning (CDRL) uses a categorical distribution with evenly spaced outcomes to model the entire distribution of returns and produces state-of-the-art empirical performance. However, using inappropriate bounds with CDRL may generate inaccurate estimated action values, which affect the policy update step and the final performance. In CDRL, the bounds of the distribution indicate the range of the action values that the agent can obtain in one task, without considering the policy’s performance and state–action pairs. The action values that the agent obtains are often far from the bounds, and this reduces the accuracy of the estimated action values. This paper describes a method of obtaining more accurate estimated action values for CDRL...
