Normalizer	Interface for data set normalization methods.

Class Summary

Class	Description
DecimalScaleNormalizer	Decimal scaling normalization method, which normalize data by moving decimal point in regard to max element in training set (by columns) Normalization is done according to formula: normalizedVector[i] = vector[i] / scaleFactor[i]
MaxMinNormalizer	MaxMin normalization method, which normalize data in regard to min and max elements in training set (by columns) Normalization is done according to formula: normalizedVector[i] = (vector[i] - min[i]) / (max[i] - min[i]) This class works fine if max and min are both positive and we want to normalize to [0,1]
MaxNormalizer	Max normalization method, which normalize data in regard to max element in training set (by columns) Normalization is done according to formula: normalizedVector[i] = vector[i] / abs(max[i])
RangeNormalizer	This class does normalization of a data set to specified range
ZeroMeanNormalizer	Normalizes data sets by shifting all values in such way that data set has mean of 0 and std deviation of 1
