Introducing Symmetries to Black Box Meta Reinforcement Learning

Kirsch, Louis, Flennerhag, Sebastian, van Hasselt, Hado et al.

Understand

Meta reinforcement learning (RL) attempts to discover new RL algorithms automatically from environment interaction.

  • In so-called black-box approaches, the policy and the learning algorithm are jointly represented by a single neural network.
  • These methods are very flexible, but they tend to underperform in terms of generalisation to new, unseen environments.
  • In this paper, we explore the role of symmetries in meta-generalisation.
