Exploration in Approximate Hyper-State Space for Meta Reinforcement Learning

Zintgraf, Luisa, Feng, Leo, Lu, Cong et al.

Understand

To rapidly learn a new task, it is often essential for agents to explore efficiently -- especially when performance matters from the first timestep.

  • One way to learn such behaviour is via meta-learning.
  • Many existing methods however rely on dense rewards for meta-training, and can fail catastrophically if the rewards are sparse.
  • Without a suitable reward signal, the need for exploration during meta-training is exacerbated.
