WebAug 22, 2024 · 5. In Deep Deterministic Policy Gradients (DDPG) method, we use two neural networks, one is Actor and the other is Critic. From actor-network, we can directly map states to actions (the output of the network directly the output) instead of outputting the probability distribution across a discrete action space. WebOct 30, 2024 · Action is determined by the same actor network in both parts. Compared with PID method, parameter adjustment is less complicated. If enough states value with various reward are taken, the parameter can suit the given environment well. It has been shown that DDPG can have better rapidity and robustness.
