In a neural network field, there are several techniques how data can be pre-processed (normalization, standardization, whitening...) in order to obtain higher accuracy of a network without changing its architecture. Even if fuzzy is broadly spread in data/image processing, I did not find any pre-processing technique based on fuzzy. There are fuzzy neural networks, but they do not realize data pre-processing without original architecture modification. Also, a transformation from the original data range into [0, 1] cannot be considered as a fuzzy pre-processing.
So, the question is: do you know some fuzzy-based data pre-processing technique?
