Goal Representations for Instruction Following: A Semi-Supervised Language Interface to Control

no code implementations30 Jun 2023 Vivek Myers, Andre He, Kuan Fang, Homer Walke, Philippe Hansen-Estruch, Ching-An Cheng, Mihai Jalobeanu, Andrey Kolobov, Anca Dragan, Sergey Levine

Our method achieves robust performance in the real world by learning an embedding from the labeled data that aligns language not to the goal image, but rather to the desired change between the start and goal images that the instruction corresponds to.

Stabilizing Contrastive RL: Techniques for Robotic Goal Reaching from Offline Data

1 code implementation6 Jun 2023 Chongyi Zheng, Benjamin Eysenbach, Homer Walke, Patrick Yin, Kuan Fang, Ruslan Salakhutdinov, Sergey Levine

Robotic systems that rely primarily on self-supervised learning have the potential to decrease the amount of human annotation and engineering effort required to learn control strategies.

Generalization with Lossy Affordances: Leveraging Broad Offline Data for Learning Visuomotor Tasks

no code implementations12 Oct 2022 Kuan Fang, Patrick Yin, Ashvin Nair, Homer Walke, Gengchen Yan, Sergey Levine

The utilization of broad datasets has proven to be crucial for generalization for a wide range of fields.

Learning Finite Linear Temporal Logic Specifications with a Specialized Neural Operator

no code implementations7 Nov 2021 Homer Walke, Daniel Ritter, Carl Trimbach, Michael Littman

Finite linear temporal logic ($\mathsf{LTL}_f$) is a powerful formal representation for modeling temporal sequences.

PLAD: Learning to Infer Shape Programs with Pseudo-Labels and Approximate Distributions

1 code implementation CVPR 2022 R. Kenny Jones, Homer Walke, Daniel Ritchie

Related to these approaches, we introduce a novel self-training variant unique to program inference, where program pseudo-labels are paired with their executed output shapes, avoiding label mismatch at the cost of an approximate shape distribution.
