On the Linear Convergence of Policy Gradient under Hadamard Parameterization

no code implementations31 May 2023 Jiacai Liu, Jinchi Chen, Ke Wei

To show the local linear convergence of the algorithm, we have indeed established the contraction of the sub-optimal probability $b_s^k$ (i. e., the probability of the output policy $\pi^k$ on non-optimal actions) when $k\ge k_0$.
