DDPG: replay and target networks for deterministic continuous-control actors

Contribution grade

Continuous-action deep reinforcement learning · Human-designed research method or resource

Reference score170,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Combined deterministic actor-critic policy gradients with replay, slowly updated targets and normalization to train deep policies over continuous actions.

Scientific scope

Combined deterministic actor-critic policy gradients with replay, slowly updated targets and normalization to train deep policies over continuous actions. Extends earlier deterministic policy-gradient algorithms and DQN stabilization, not invention of either. More than20simulated physics tasks and selected pixel-control results do not ensure convergence, physical deployment safety or universal control performance; first two authors source-marked equal contribution.

Evidence

The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
