Class Summary
HeDESNormalizationOutlierScaling Normalization used by HeDES
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.Parameterizer Parameterization class.
MinusLogStandardDeviationScaling Scaling that can map arbitrary values to a probability in the range of [0:1].
MinusLogStandardDeviationScaling.Parameterizer Parameterization class.
MixtureModelOutlierScalingFunction Tries to fit a mixture model (exponential for inliers and gaussian for outliers) to the outlier score distribution.
MultiplicativeInverseScaling Scaling function to invert values basically 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.Parameterizer Parameterization class.
OutlierLinearScaling Scaling that can map arbitrary values to a probability in the range of [0:1].
OutlierLinearScaling.Parameterizer Parameterization class.
OutlierMinusLogScaling Scaling function to invert values by computing -1 * Math.log(x) Useful for example for scaling ABOD, but see MinusLogStandardDeviationScaling and MinusLogGammaScaling for more advanced scalings for this algorithm.
OutlierSqrtScaling Scaling that can map arbitrary positive values to a value in the range of [0:1].
OutlierSqrtScaling.Parameterizer Parameterization class.
RankingPseudoOutlierScaling This is a pseudo outlier scoring obtained by only considering the ranks of the objects.
SigmoidOutlierScalingFunction 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.Parameterizer Parameterization class.
StandardDeviationScaling Scaling that can map arbitrary values to a probability in the range of [0:1].
StandardDeviationScaling.Parameterizer Parameterization class.
TopKOutlierScaling Outlier scaling function that only keeps the top k outliers.
TopKOutlierScaling.Parameterizer Parameterization class.
