Efficient Data Collection for Robotic Manipulation via Compositional Generalization

no code implementations8 Mar 2024 Jensen Gao, Annie Xie, Ted Xiao, Chelsea Finn, Dorsa Sadigh

Recent works on large-scale robotic data collection typically vary a wide range of environmental factors during data collection, such as object types and table textures.

Bootstrapping Adaptive Human-Machine Interfaces with Offline Reinforcement Learning

no code implementations7 Sep 2023 Jensen Gao, Siddharth Reddy, Glen Berseth, Anca D. Dragan, Sergey Levine

We further evaluate on a simulated Sawyer pushing task with eye gaze control, and the Lunar Lander game with simulated user commands, and find that our method improves over baseline interfaces in these domains as well.

Physically Grounded Vision-Language Models for Robotic Manipulation

no code implementations5 Sep 2023 Jensen Gao, Bidipta Sarkar, Fei Xia, Ted Xiao, Jiajun Wu, Brian Ichter, Anirudha Majumdar, Dorsa Sadigh

We incorporate this physically grounded VLM in an interactive framework with a large language model-based robotic planner, and show improved planning performance on tasks that require reasoning about physical object concepts, compared to baselines that do not leverage physically grounded VLMs.

Distance Weighted Supervised Learning for Offline Interaction Data

1 code implementation26 Apr 2023 Joey Hejna, Jensen Gao, Dorsa Sadigh

To bridge the gap between IL and RL, we introduce Distance Weighted Supervised Learning or DWSL, a supervised method for learning goal-conditioned policies from offline data.

ASHA: Assistive Teleoperation via Human-in-the-Loop Reinforcement Learning

no code implementations5 Feb 2022 Sean Chen, Jensen Gao, Siddharth Reddy, Glen Berseth, Anca D. Dragan, Sergey Levine

Building assistive interfaces for controlling robots through arbitrary, high-dimensional, noisy inputs (e. g., webcam images of eye gaze) can be challenging, especially when it involves inferring the user's desired action in the absence of a natural 'default' interface.
