Uses of AbstractStreamFilter in elki.datasource.filter.normalization.instancewise

Subclasses of AbstractStreamFilter in elki.datasource.filter.normalization.instancewise

Modifier and Type	Class	Description
class	HellingerHistogramNormalization<V extends elki.data.NumberVector>	Normalize histograms by scaling them to unit absolute sum, then taking the square root of the absolute value in each attribute, times the normalization constant \(1/\sqrt{2}\).

class	InstanceMinMaxNormalization<V extends elki.data.NumberVector>	Normalize vectors with respect to a given minimum and maximum in each dimension.
class	InstanceRankNormalization<V extends elki.data.NumberVector>	Normalize vectors such that the smallest value of each instance is 0, the largest is 1.
class	LengthNormalization<V extends elki.data.NumberVector>	Class to perform a normalization on vectors to norm 1.
class	Log1PlusNormalization<V extends elki.data.NumberVector>	Normalize the data set by applying \( \frac{\log(1+|x|b)}{\log 1+b} \) to any value.
