Knowledge-Guided Exploration in Deep Reinforcement Learning
Not on the map. Why?
Abstract (arXiv)
This paper proposes a new method to drastically speed up deep reinforcement learning (deep RL) training for problems that have the property of state-action permissibility (SAP). Two types of permissibility are defined under SAP. The first type says that after an action at is performed in a state st and the agent has reached the new state st+1, the agent can decide whether at is permissible or not permissible in st. The second type says that even without performing at in st, the agent can already decide whether at is permissible or not in st. An action is not permissible in a state if the action can never lead to an optimal solution and thus should not be tried (over and over again). We incorporate the proposed SAP property and encode action permissibility knowledge into two state-of-the-art deep RL algorithms to guide their state-action exploration together with a virtual stopping strategy. Results show that the SAP-based guidance can markedly speed up RL training.
