New Q-learning framework offers stable infinite-dimensional linear approximation

Researchers have developed a novel framework for stable Q-learning using infinite-dimensional linear function approximation. This approach addresses instability issues in traditional Q-learning by preserving the Bellman contraction through a reconstruction and compression operator. The framework's learning variable is a coefficient field on a compact latent metric space, and it offers convergence bounds of order \(\\widetilde O(n^{-1/2})\). This method provides a powerful abstraction for understanding statistical difficulty and can adapt to the geometry and smoothness of the latent space. AI
