Proximal Policy Optimization

Definition

Proximal Policy Optimization (PPO) is a reinforcement learning algorithm used to train agents to make better decisions in complex environments. PPO seeks to improve a policy by taking small, conservative steps, preventing large policy changes that could destabilize the learning process. It balances ease of implementation with strong performance, making it a popular choice for training agents in various simulation and real-world control tasks. The algorithm optimizes an agent’s actions by maximizing expected rewards within certain constraints.
