Why use this standardization method in the Analytics? #21

Why use 'x = (x-mean)/mean' standardization In line 15 of file analyze_kmeans.py? Why not use max-min standardization or z-score standardization ？

13o-bbr-bbq commented 6 years ago

in my past experiment, accuracy of x = (x-mean)/mean is higher than max-min, z-score.
but, i'll try to use max-min, z-score again.
thanks for your advise!!
