WebJun 4, 2024 · Introduction. Deep Deterministic Policy Gradient (DDPG) is a model-free off-policy algorithm for learning continous actions. It combines ideas from DPG (Deterministic Policy Gradient) and DQN (Deep Q-Network). It uses Experience Replay and slow-learning target networks from DQN, and it is based on DPG, which can operate over continuous …
