Train DDPG Agent with Pretrained Actor Network - MathWorks
WebMay 26, 2024 · The target actor’s parameters are updated periodically to match the agent’s actor parameters. Actor Updates Similar to single-agent DDPG, we use the deterministic policy gradient to update each of the agent’s actor parameters. where mu denotes an agent’s actor. Let’s dig into this update equation just a little bit. WebMay 12, 2024 · MADDPG is the multi-agent counterpart of the Deep Deterministic Policy Gradients algorithm (DDPG) based on the actor-critic framework. While in DDPG, we have just one agent. Here we have multiple agents with their own actor and critic networks. dawson creek kijiji
