WebDec 30, 2024 · Some other modifications to the agent, such as Dueling Network Architectures (Wang et al., 2015), can be added to this implementation to improve the agent’s performance. The algorithm is also generalizable to other environments. Web其中actor和target部分的网络参数会延迟更新，也就是说critic1和critic2参数在不断更新，训练好critic之后才能知道actor做出理想的动作。Critic网络更新的频率要比Actor网络更新的频率要大（类似GAN的思想，先训练好Critic才能更好的对actor指指点点）。1、运用两个Critic网络。
