We can learn a model that provides shaped "process rewards" for robotic RL, that evolves automatically as the policy gets better. This improves performance on benchmarks, and works in the real world! Some fun new work with Raymond Tsao & Andrew Wagenmaker

In the real world, this leads to drastically faster learning, in just a few thousand time steps.

@ajwagenmaker This is cool! Every time I do robotics research I remember dense reward is still overpowered for task mastery, and the more self supervised we can learn the better :)

@ajwagenmaker Cool!

@ajwagenmaker Does that hold with actual robots, or just in simulation?
