Want to scale robot data with simulation, but don’t know how to get large numbers of realistic, diverse, and task-relevant scenes?

Our solution:
➊ Pretrain on broad procedural scene data
➋ Steer generation toward downstream objectives

Scaling imitation learning has been bottlenecked by the need for high-quality robot data, which are expensive to collect. But are we utilizing existing data to the fullest extent? A thread (1/11)
