Learning to Compose Skills

Understand

We present a differentiable framework capable of learning a wide variety of compositions of simple policies that we call skills.

  • By recursively composing skills with themselves, we can create hierarchies that display complex behavior.
  • Skill networks are trained to generate skill-state embeddings that are provided as inputs to a trainable composition function, which in turn outputs a policy for the overall task.
  • Our experiments on an environment consisting of multiple collect and evade tasks show that this architecture is able to quickly build complex skills from simpler ones.
