Proximal Policy Optimization (PPO) - Hugging Face
Aug 5, 2022 · Today we'll learn about Proximal Policy Optimization (PPO), an architecture that improves our agent's training stability by avoiding too large policy updates. To do that, we use a ratio that will indicates the difference between our current and old policy and clip this ratio from a specific range [1 - \epsilon, 1 + \epsilon] [1−ϵ,1+ϵ] .
PPO — Intuitive guide to state-of-the-art Reinforcement Learning
Dec 15, 2022 · PPO is a (model-free) Policy Optimization Gradient-based algorithm. The algorithm aims to learn a policy that maximizes the obtained cumulative rewards given the experience during training.
