Class Summary

Class	Description
COPOutlierScaling	CDF based outlier score scaling.
COPOutlierScaling.Par	Parameterization class.
HeDESNormalizationOutlierScaling	Normalization used by HeDES
LogRankingPseudoOutlierScaling	This is a pseudo outlier scoring obtained by only considering the ranks of the objects.
MinusLogGammaScaling	Scaling that can map arbitrary values to a probability in the range of [0:1], by assuming a Gamma distribution on the data and evaluating the Gamma CDF.
MinusLogGammaScaling.Par	Parameterization class.
MinusLogStandardDeviationScaling	Scaling that can map arbitrary values to a probability in the range of [0:1].
MinusLogStandardDeviationScaling.Par	Parameterization class.
MixtureModelOutlierScaling	Tries to fit a mixture model (exponential for inliers and gaussian for outliers) to the outlier score distribution.
MultiplicativeInverseScaling	Scaling function to invert values by computing 1/x, but in a variation that maps the values to the [0:1] interval and avoiding division by 0.
OutlierGammaScaling	Scaling that can map arbitrary values to a probability in the range of [0:1] by assuming a Gamma distribution on the values.
OutlierGammaScaling.Par	Parameterization class.
OutlierLinearScaling	Scaling that can map arbitrary values to a value in the range of [0:1].
OutlierLinearScaling.Par	Parameterization class.
OutlierMinusLogScaling	Scaling function to invert values by computing -log(x)
OutlierSqrtScaling	Scaling that can map arbitrary positive values to a value in the range of [0:1].
OutlierSqrtScaling.Par	Parameterization class.
RankingPseudoOutlierScaling	This is a pseudo outlier scoring obtained by only considering the ranks of the objects.
SigmoidOutlierScaling	Tries to fit a sigmoid to the outlier scores and use it to convert the values to probability estimates in the range of 0.0 to 1.0
SqrtStandardDeviationScaling	Scaling that can map arbitrary values to a probability in the range of [0:1].
SqrtStandardDeviationScaling.Par	Parameterization class.
StandardDeviationScaling	Scaling that can map arbitrary values to a probability in the range of [0:1].
StandardDeviationScaling.Par	Parameterization class.
TopKOutlierScaling	Outlier scaling function that only keeps the top k outliers.
