Deep Deterministic Policy Gradient — Spinning Up documentation …
Deep Deterministic Policy Gradient (DDPG) is an algorithm which concurrently learns a Q-function and a policy. It uses off-policy data and the Bellman equation to learn the Q-function, and uses …
Part 3: Intro to Policy Optimization — Spinning Up documentation …
In this section, we’ll discuss the mathematical foundations of policy optimization algorithms, and connect the material to sample code. We will cover three key results in the theory of policy …
Twin Delayed DDPG — Spinning Up documentation - OpenAI
Twin Delayed DDPG (TD3) is an algorithm that addresses this issue by introducing three critical tricks: Trick One: Clipped Double-Q Learning. TD3 learns two Q-functions instead of one …
Soft Actor-Critic — Spinning Up documentation - OpenAI
Soft Actor Critic (SAC) is an algorithm that optimizes a stochastic policy in an off-policy way, forming a bridge between stochastic policy optimization and DDPG-style approaches.
