Package de.lmu.ifi.dbs.elki.utilities.scaling.outlier

Scaling of Outlier scores, that require a statistical analysis of the occurring values

See:
          Description

Interface Summary
OutlierScalingFunction Interface for scaling functions used by Outlier evaluation such as Histograms and visualization.
 

Class Summary
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.
MinusLogStandardDeviationScaling Scaling that can map arbitrary values to a probability in the range of [0:1].
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.
OutlierLinearScaling Scaling that can map arbitrary values to a probability in the range of [0:1].
OutlierMinusLogScaling Scaling function to invert values by computing -1 * Math.log(x)
OutlierSqrtScaling Scaling that can map arbitrary positive values to a value in the range of [0:1].
SqrtStandardDeviationScaling Scaling that can map arbitrary values to a probability in the range of [0:1].
StandardDeviationScaling Scaling that can map arbitrary values to a probability in the range of [0:1].
TopKOutlierScaling Outlier scaling function that only keeps the top k outliers.
