总结的超级好,谢谢博主! |

代码部分我有一个小小的疑问:为什么actor的输出(即输入state,产生action的概率)要命名为dist呀?是distance的简写吗? |
我理解成是动作的分布,所以是distribution的意思

啊啊,是哈,我疏忽了,Thanks♪(・ω・)ノ |
啊,代码部分我还有一个critic_loss计算问题:是Q_value(old)-critic_value(new),这样算的吗?不知道理解的对不对~ |
请问博主PPO算法里的θk多久更新一次?如果是每次迭代都更新的话,那采样效率岂不是依然不高? |
update policy every n steps
看代码,频率可以自己设置的。 |
critic_loss = (returns - values).pow(2).mean() |
