Efficiently Escaping Saddle Points for Non-Convex Policy Optimization

no code implementations15 Nov 2023 Sadegh Khorasani, Saber Salehkaleybar, Negar Kiyavash, Niao He, Matthias Grossglauser

Policy gradient (PG) is widely used in reinforcement learning due to its scalability and good performance.

Momentum-Based Policy Gradient with Second-Order Information

no code implementations17 May 2022 Saber Salehkaleybar, Sadegh Khorasani, Negar Kiyavash, Niao He, Patrick Thiran

SHARP algorithm is parameter-free, achieving $\epsilon$-approximate first-order stationary point with $O(\epsilon^{-3})$ number of trajectories, while using a batch size of $O(1)$ at each iteration.
