Automatic Discovery of Subgoals in Reinforcement Learning using Diverse Density

  title={Automatic Discovery of Subgoals in Reinforcement Learning using Diverse Density},
  author={Amy McGovern and Andrew G. Barto},
This paper presents a method by which a reinforcement learning agent can automatically discover certain types of subgoals online. By creating useful new subgoals while learning, the agent is able to accelerate learning on the current task and to transfer its expertise to other, related tasks through the reuse of its ability to attain subgoals. The agent discovers subgoals based on commonalities across multiple paths to a solution. We cast the task of finding these commonalities as a multiple… CONTINUE READING
