Normalize (attribute)
Package
weka.filters.unsupervised.attribute
Synopsis
Normalizes all numeric values in the given dataset (apart from the class attribute, if set). The resulting values are by default in 0,1 for the data used to compute the normalization intervals. But with the scale and translation parameters one can change that, e.g., with scale = 2.0 and translation = -1.0 you get values in the range [-1,+1].
