PPO Algorithm

Definitions

1. Proximal Policy Optimization, a reinforcement-learning algorithm often used in policy training and historically common in RLHF pipelines.

   In plain English: A reinforcement-learning method often used to train behavior in AI systems.

   Example: "The original alignment stack relied on the PPO algorithm after preference modeling."
