How to generate the param_whitening.pkl?

[qingtianwu]

Hello,

I am very impressed by your wonderfull work. But I met one problem that:

param_std = meta.get('param_std')
param_mean = meta.get('param_mean')

The 'meta' come from the "param_whitening.pkl" file. I wonder how to calculate the two variables, i.e., param_std and param_mean? Or how to generate the "param_whitening.pkl" file?

Looking forward to your reply.

Best
