There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract: The objective of the proposed research is to investigate the human-in-the-loop reinforcement learning (RL) in an interpretable way via inductive logic programming (ILP). Although the state-of-art deep RL algorithms have achieved success in many fields from robotic control to video-based games, few of them have been deployed into real-world applications. It is primarily prohibited by data inefficiency and lack of interpretability. To tackle these problems, the proposed research is primarily to investigate the interpretable RL with human in the loop. Since ILP is a popular and powerful tool to induce logic rules from practical data, to realize the interpretability of deep RL algorithms, we adopt ILP models based on modern differentiable deep neural architectures to learn interpretable policies or transitions models. Further, to improve sample efficiency, we incorporate human assistance into the learning loop of RL agent. We propose to investigate interpretable hierarchical RL, interpretable RL with human feedback, and text-based games as an application example.
