Yell At Your Robot: Improving On-the-Fly from Language Corrections

no code implementations19 Mar 2024 Lucy Xiaoyang Shi, Zheyuan Hu, Tony Z. Zhao, Archit Sharma, Karl Pertsch, Jianlan Luo, Sergey Levine, Chelsea Finn

In this paper, we make the following observation: high-level policies that index into sufficiently rich and expressive low-level language-conditioned skills can be readily supervised with human feedback in the form of language corrections.

Waypoint-Based Imitation Learning for Robotic Manipulation

no code implementations26 Jul 2023 Lucy Xiaoyang Shi, Archit Sharma, Tony Z. Zhao, Chelsea Finn

AWE can be combined with any BC algorithm, and we find that AWE can increase the success rate of state-of-the-art algorithms by up to 25% in simulation and by 4-28% on real-world bimanual manipulation tasks, reducing the decision making horizon by up to a factor of 10.

Skill-based Model-based Reinforcement Learning

no code implementations15 Jul 2022 Lucy Xiaoyang Shi, Joseph J. Lim, Youngwoon Lee

From this intuition, we propose a Skill-based Model-based RL framework (SkiMo) that enables planning in the skill space using a skill dynamics model, which directly predicts the skill outcomes, rather than predicting all small details in the intermediate states, step by step.
