Defensive Policy Gradient algorithm improves reinforcement learning sample complexity

A new algorithm called Defensive Policy Gradient (DPG) has been developed, which improves upon existing variance-reduced policy gradient methods for reinforcement learning. Unlike previous approaches that required unrealistic assumptions about variance, DPG achieves an improved sample complexity of O(ε−3) without such constraints. The research also establishes theoretical lower bounds for policy optimization, suggesting that DPG's faster rate is optimal. AI
