One-Shot Hierarchical Imitation Learning of Compound Visuomotor Tasks

Yu, Tianhe, Abbeel, Pieter, Levine, Sergey et al.

Understand

We consider the problem of learning multi-stage vision-based tasks on a real robot from a single video of a human performing the task, while leveraging demonstration data of subtasks with other objects.

  • This problem presents a number of major challenges.
  • Video demonstrations without teleoperation are easy for humans to provide, but do not provide any direct supervision.
  • Learning policies from raw pixels enables full generality but calls for large function approximators with many parameters to be learned.
