Abstract base class for streaming filters that produce vectors.
• ### Uses of AbstractStreamConversionFilter in de.lmu.ifi.dbs.elki.datasource.filter.normalization.instancewise

Modifier and Type Class and Description
class  HellingerHistogramNormalization<V extends 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  InstanceLogRankNormalization<V extends NumberVector>
Normalize vectors such that the smallest value of each instance is 0, the largest is 1, but using $$\log_2(1+x)$$.
class  InstanceMeanVarianceNormalization<V extends NumberVector>
Normalize vectors such that they have zero mean and unit variance.
class  InstanceMinMaxNormalization<V extends NumberVector>
Normalize vectors with respect to a given minimum and maximum in each dimension.
class  InstanceRankNormalization<V extends NumberVector>
Normalize vectors such that the smallest value of each instance is 0, the largest is 1.
class  LengthNormalization<V extends NumberVector>
Class to perform a normalization on vectors to norm 1.
class  Log1PlusNormalization<V extends NumberVector>
Normalize the data set by applying $$\frac{\log(1+|x|b)}{\log 1+b}$$ to any value.
