New analysis explores faster convergence for Natural Actor-Critic algorithms

Researchers have analyzed a single-loop, entropy-regularized Natural Actor-Critic algorithm, focusing on its convergence rates for unregularized objectives. The study explores two optimization regimes: Stochastic, using a joint Lyapunov recurrence, and Deterministic, employing Policy Mirror Descent. By introducing an Exponential Translation mechanism and exploiting a positive Minimal Action Gap, the algorithm achieves accelerated convergence rates, outperforming existing methods in specific settings.
