Webb13 jan. 2024 · Note that despite both A2C and DDPG belonging to the A2C family, critic is used in different ways. In A2C, critic is used as a baseline for calculating advantage for improving stability. In DDPG, as our policy is deterministic, we can calculate the gradient from Q, obtained from critic up to actor’s weights, so the whole system is end-to-end … cheetah hard case cylindercle https://ashleysauve.com
