Interface Summary

Normalization<O extends DatabaseObject>

Normalization performs a normalization on a set of feature vectors and is capable to transform a set of feature vectors to the original attribute ranges.

Class Summary

AbstractNormalization<O extends DatabaseObject>	Abstract super class for all normalizations.
AttributeWiseMinMaxNormalization<V extends NumberVector<V,?>>	Class to perform and undo a normalization on real vectors with respect to given minimum and maximum in each dimension.
AttributeWiseVarianceNormalization<V extends NumberVector<V,?>>	Class to perform and undo a normalization on real vectors with respect to given mean and standard deviation in each dimension.
DummyNormalization<O extends DatabaseObject>	Dummy normalization that does nothing.
MultiRepresentedObjectNormalization<O extends DatabaseObject>	Class to perform and undo a normalization on multi-represented objects with respect to given normalizations for each representation.

Exception Summary

NonNumericFeaturesException

An exception to signal the encounter of non numeric features where numeric features have been expected.
