Package elki.outlier.trivial

Class TrivialGeneratedOutlier

java.lang.Object

elki.outlier.trivial.TrivialGeneratedOutlier

All Implemented Interfaces:

Algorithm, OutlierAlgorithm

public class TrivialGeneratedOutlier
extends java.lang.Object
implements OutlierAlgorithm

Extract outlier score from the model the objects were generated by.

This algorithm can only be applied to data that was freshly generated, to the generator model information is still available.

Since:

0.5.0
