New estimator advances quantile distributional reinforcement learning accuracy

Researchers have developed a new estimator for quantile distributional reinforcement learning, aiming to accurately approximate the return distribution under a given policy. The study establishes non-asymptotic error bounds for this estimator, particularly under Wasserstein distances, and analyzes its performance across various quantile resolutions. The findings reveal that the estimator can achieve a root-n high-probability bound simultaneously over all resolutions under certain conditions, while also characterizing the exact local asymptotic minimax risk.
