Exact Preprocessing

[CapnBloodBeard12345]

Hi I am trying to get some clarity on marrying the preprocessing mentioned in your paper versus what I see happening in this repo.

The preprocessing I see occurring in this repo is mean pose subtraction and division by the standard deviation pose. However, when I read your paper it appears that you are saying that your remove the translation about the XZ plane and the rotation about the Y-axis while specifying a fixed "forward" direction and rotating the skeleton to move in this direction. Am I misinterpreting something here?

Also, out of curiosity, I have used your read_all_data method from src/translate.py and have noticed that the inputs to your network seem belone to the range [-30,30] and I am wondering if you encountered any instability issues during training, or did you apply some further standarization to get the inputs in the range [-1,1]?

Thanks in advance for your help!
