WARP-RM: A Warp-Augmented Relative Progress Reward Model for Data Curation

Justin Yu, Andrew Goldberg, Kavish Kondap +7

Scaling imitation learning requires large datasets, yet human teleoperation inevitably produces mixed-quality demonstrations containing hesitations and recoveries. Prior frame-leve…

Scalable Behavior Cloning with Open Data, Training, and Evaluation

Arthur Allshire, Himanshu Gaurav Singh, Ritvik Singh +15

We introduce ABC, a fully open-source stack for manipulation with behavior cloning. At its core is ABC-130K: the largest open-source teleoperation dataset to date, featuring 3,500…
