Learning from Ambiguous Demonstrations with Self-Explanation Guided Reinforcement Learning

AAAI 2024technical

Our work aims at efficiently leveraging ambiguous demonstrations for the training of a reinforcement learning (RL) agent. An ambiguous demonstration can usually be interpreted in multiple ways, which severely hinders the RL agent from learning stably and efficiently. Since an optimal demonstration m…

Contrastively Learning Visual Attention as Affordance Cues from Demonstrations for Robotic Grasping

IROS 2021poster

Conventional works that learn grasping affordance from demonstrations need to explicitly predict grasping configurations, such as gripper approaching angles or grasping preshapes. Classic motion planners could then sample trajectories by using such predicted configurations. In this work, our goal is…
