WebMy understanding from the DDPG paper was that batch norm was mostly used to compensate for the diverse input spaces of the experiments they used (so a single hyperparam setting for everything else would be more flexible). That's as opposed to DQN on Atari games which all have similar input distributions. WebBATCH-SIZE is primarily intended to limit the number of rows added to a top buffer in a ProDataSet, or to a non-top buffer whose parent table normally has only one row. However, it can be set at any level of the hierarchy. The counter used to compare the rows read against the BATCH-SIZE for a buffer is reset for every FILL action.
WebTwin Delayed DDPG (TD3) Addressing Function Approximation Error in Actor-Critic Methods. TD3 is a direct successor of DDPG and improves it using three major tricks: clipped double Q-Learning, delayed policy update and target policy smoothing. We recommend reading OpenAI Spinning guide on TD3 to learn more about those.

WebSep 21, 2024 · DDPG uses two more techniques not present in the original DQN: **First, it uses two Target networks.** **Why?** Because it add stability to training. In short, we are learning from estimated targets and Target networks are updated slowly, hence keeping our estimated targets stable.
