  Abstract: We study the computational tractability of provably sample-efficient (PAC) reinforcement learning in episodic environments with high-dimensional observations. We present new sample efficient algorithms for environments with deterministic hidden state dynamics but stochastic rich observations. These methods represent computationally efficient alternatives to prior algorithms that rely on enumerating exponentially many functions. We show that the only known statistically efficient algorithm for the more general stochastic transition setting requires NP-hard computation which cannot be implemented via standard optimization primitives. We also present several examples that illustrate fundamental challenges of tractable PAC reinforcement learning in such general settings.
