How can we speed up the DQN training process?

ByAdmin October 9, 2021October 9, 2021

Use a smaller model.

Do not use pooling.

Stack more layers.

Use stacked state and action as input.

Use smaller input.

Use upsampling.

Use strides.

Parallelize learning.

Stack 4 last states together.

Question 6

What are the possible ways to improve experience replay (buffer)?

1 point

Use smaller buffer (up to 1 thousand).

Sample whole sessions from an experience replay instead of single experience (S,A,R,S’) tuples.

Use larger buffer (up to 1 million).

Use samples more wisely – taking into account their contribution to the training process.

Add more statistics to it, such as gamma, current learning rate, current step/epoch.
