Distilling and Retrieving Generalizable Knowledge for Robot Manipulation via Language Corrections

1 code implementation17 Nov 2023 Lihan Zha, Yuchen Cui, Li-Heng Lin, Minae Kwon, Montserrat Gonzalez Arenas, Andy Zeng, Fei Xia, Dorsa Sadigh

DROC is able to respond to a sequence of online language corrections that address failures in both high-level task plans and low-level skill primitives.

"No, to the Right" -- Online Language Corrections for Robotic Manipulation via Shared Autonomy

1 code implementation6 Jan 2023 Yuchen Cui, Siddharth Karamcheti, Raj Palleti, Nidhya Shivakumar, Percy Liang, Dorsa Sadigh

Instead of discrete turn-taking between a human and robot, LILAC splits agency between the human and robot: language is an input to a learned model that produces a meaningful, low-dimensional control space that the human can use to guide the robot.

The EMPATHIC Framework for Task Learning from Implicit Human Feedback

1 code implementation28 Sep 2020 Yuchen Cui, Qiping Zhang, Alessandro Allievi, Peter Stone, Scott Niekum, W. Bradley Knox

We train a deep neural network on this data and demonstrate its ability to (1) infer relative reward ranking of events in the training task from prerecorded human facial reactions; (2) improve the policy of an agent in the training task using live human facial reactions; and (3) transfer to a novel domain in which it evaluates robot manipulation trajectories.
