I saw several comparison between SGD, RMSPROP and ADAM but what I am looking for is their comparsion in DQN algorithm?

What is best to select as optimizer SGD or Adam in DQN? Why?

Please check the accuracy of my thinking:

-What is their main differences?

  • Adam is more stable than SGD in training of DQN?

  • Speed of convergence of ADAM is more in training of DQN? why? Because of considering 2 coefficient?

  • In Testing case SGD with momentum is more stable than ADAM?why?

-the speed of convergence of Adam and adaptive approach is more higher but in long time SGD has a better performance? if correct why?

-What we are able to say in comparison between ADAM and RMSPROP?
