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 … WebApr 9, 2024 · Deriving the policy gradient We need to retrieve an explicit gradient of the objective function. Let’s go through it step by step. We start by taking the gradient of the expected rewards: Step 1: express as gradient of expected reward As seen before, we can rewrite this to the sum over all trajectory probabilities multiplied by trajectory rewards:
