WebOct 26, 2024 · Download PDF Abstract: Policy optimization is a fundamental principle for designing reinforcement learning algorithms, and one example is the proximal policy optimization algorithm with a clipped surrogate objective (PPO-Clip), which has been popularly used in deep reinforcement learning due to its simplicity and effectiveness. …
WebJan 27, 2024 · The Clipped Surrogate Objective is a drop-in replacement for the policy gradient objective that is designed to improve training stability by limiting the change you make to your policy at each step. For vanilla policy gradients (e.g., REINFORCE) — which you should be familiar with, or familiarize yourself with before you read this — the ...
