This paper uses image augmentation to improve RL algorithms. It contains the following paragraph - "Our approach, DrQ, is the union of the three separate regularization mechanisms introduced above:
- transformations of the input image (Section 3.1).
- averaging the Q target over K image transformations (Equation (1)).
- averaging the Q function itself over M image transformations (Equation (3))."
I do not understand how part 2 and 3 (Equation 1 and 3) and would highly appreciate some detailed elaboration on it.
Here are the equations -
