On Oracle-Efficient PAC RL with Rich Observations

Dann, Christoph, Jiang, Nan, Krishnamurthy, Akshay et al.

Understand

We study the computational tractability of PAC reinforcement learning with rich observations.

  • We present new provably sample-efficient algorithms for environments with deterministic hidden state dynamics and stochastic rich observations.
  • These methods operate in an oracle model of computation -- accessing policy and value function classes exclusively through standard optimization primitives -- and therefore represent computationally efficient alternatives to prior algorithms that require enumeration.
  • With stochastic hidden state dynamics, we prove that the only known sample-efficient algorithm, OLIVE, cannot be implemented in the oracle model.
