de.lmu.ifi.dbs.elki.datasource.filter.normalization.instancewise |
Instancewise normalization, where each instance is normalized independently.
|
Class and Description |
---|
HellingerHistogramNormalization
Normalize histograms by scaling them to L1 norm 1, then taking the square
root in each attribute.
|
InstanceLogRankNormalization
Normalize vectors such that the smallest value of each instance is 0, the
largest is 1, but using log_2(1+x).
|
InstanceMeanVarianceNormalization
Normalize vectors such that they have zero mean and unit variance.
|
InstanceMinMaxNormalization
Normalize vectors such that the smallest attribute is 0, the largest is 1.
|
InstanceRankNormalization
Normalize vectors such that the smallest value of each instance is 0, the
largest is 1.
|
LengthNormalization
Class to perform a normalization on vectors to norm 1.
|
Log1PlusNormalization
Normalize the data set by applying log(1+|x|*b)/log(b+1) to any value.
