Questions about the data normalization #25
Comments
|
Thanks for your reply! One more question, when the program is being used in production environment, is there any difference between using local mean and variance from each input file and using global train mean and stdvariance? If so, which should I choose? |
Hi Kim,
Apologize for disturbing you for many times, but I have problem understanding your normalization code. I found some code in the
acoustic_feat_ex.m
:and in every
data_reader_XXX.py
:My questions are:
acoustic_feat_ex.m
? Why don't calculate factor for every single train file and apply normalization on it?data_reader_XXX.py
s are also used during the prediction)? Is this a mistake?Thanks in advance!
