New framework uses Hilbert space for multi-dimensional reinforcement learning

A new research paper introduces KE-DRL, a framework for multi-dimensional distributional reinforcement learning that utilizes Hilbert space mappings. This approach estimates the kernel mean embedding of multi-dimensional value distributions, replacing computationally intensive Wasserstein metrics with integral probability metrics. The method is designed for complex, continuous state-action spaces and offers theoretical guarantees for convergence and contraction properties, demonstrating robust off-policy evaluation in simulations.
