Learning Robot Skills with Temporal Variational Inference

Shankar, Tanmay, Gupta, Abhinav

Understand

In this paper, we address the discovery of robotic options from demonstrations in an unsupervised manner.

  • Specifically, we present a framework to jointly learn low-level control policies and higher-level policies of how to use them from demonstrations of a robot performing various tasks.
  • By representing options as continuous latent variables, we frame the problem of learning these options as latent variable inference.
  • We then present a temporal formulation of variational inference based on a temporal factorization of trajectory likelihoods,that allows us to infer options in an unsupervised manner.
