强化学习常见算法的实现,Q-Learning/DQN/PG/AC/DDPG/PPO/SAC
You have done a very nice work! I have some questions to ask you...
In the RL-demo/PPO/agent.py folder, I see the loss function in the 70th line. I think the function, that you have written, should be ppo_actor's objective function, which is expected to be larger. However, ppo_actor's loss should be smaller... So, is a minus sign missing here? Or, is my understanding of PPO not deep enough? Expect your answer!
The following is a Chinese translation.
大佬你好,我观察到在你RL-demo/PPO/agent.py的第70行里面出现了PPO_actor的loss公式,但是我觉得那个应该是PPO_actor的目标函数,即一个越大越好的指标,Loss应该是越小越好的。所以这里是不是缺了一个负号?还是我对公式的理解不够透彻?希望您不吝赐教。
