ELA: Exploited Level Augmentation for Offline Learning in Zero-Sum Games

no code implementations28 Feb 2024 Shiqi Lei, Kanghoon Lee, Linjing Li, Jinkyoo Park, Jiachen Li

Offline learning has become widely used due to its ability to derive effective policies from offline datasets gathered by expert demonstrators without interacting with the environment directly.

Interactive Autonomous Navigation with Internal State Inference and Interactivity Estimation

no code implementations27 Nov 2023 Jiachen Li, David Isele, Kanghoon Lee, Jinkyoo Park, Kikuo Fujimura, Mykel J. Kochenderfer

Moreover, we propose an interactivity estimation mechanism based on the difference between predicted trajectories in these two situations, which indicates the degree of influence of the ego agent on other agents.

Robust Driving Policy Learning with Guided Meta Reinforcement Learning

no code implementations19 Jul 2023 Kanghoon Lee, Jiachen Li, David Isele, Jinkyoo Park, Kikuo Fujimura, Mykel J. Kochenderfer

Although deep reinforcement learning (DRL) has shown promising results for autonomous navigation in interactive traffic scenarios, existing work typically adopts a fixed behavior policy to control social vehicles in the training environment.
