Query: Diversity-Inducing Policy Gradient: Using Maximum Mean Discrepancy to
  Find a Set of Diverse Policies   Standard reinforcement learning methods aim to master one way of solving a
task whereas there may exist multiple near-optimal policies. Being able to
identify this collection of near-optimal policies can allow a domain expert to
efficiently explore the space of reasonable solutions. Unfortunately, existing
approaches that quantify uncertainty over policies are not ultimately relevant
to finding policies with qualitatively distinct behaviors. In this work, we
formalize the difference between policies as a difference between the
distribution of trajectories induced by each policy, which encourages diversity
with respect to both state visitation and action choices. We derive a
gradient-based optimization technique that can be combined with existing policy
gradient methods to now identify diverse collections of well-performing
policies. We demonstrate our approach on benchmarks and a healthcare task.
