Researchers have developed a novel second-order actor-critic method for reinforcement learning in discounted Markov Decision Processes. This approach aims to accelerate convergence by incorporating curvature information from the policy Hessian, overcoming the computational complexity typically associated with second-order optimization in RL. The method leverages Hessian-vector product computations within a two-timescale framework, treating the critic as quasi-stationary during actor updates for efficiency and stability. AI
