It is intuitive that different actions prefer different information in human decisions. However, classical reinforcement learning models use the same information process procedure for all actions. In order to imitate human decision-making process closer, in this paper we investigate a new policy model, i.e., Action-Specific Focuses (ASF) framework, which enables different focuses when learning different actions. In the ASF framework, the whole action set is taken as part of the queries for the attention module, in which state-dependent action-specific features can be generated. Through extracting different action-specific features, our approach enables the agent to learn the action-focus map for each action separately. The ASF framework is also different from the previous usages of attention mechanisms in reinforcement learning that are mostly based on the state. Experiments on the Atari benchmark show that ASF is able to improve the performance in various types of games. Moreover, the visualizations of the attention weights suggest that ASF can learn meaningful focuses when taking different actions. |
