Package elki.outlier.trivial

Class TrivialGeneratedOutlier

  • All Implemented Interfaces:
    elki.Algorithm, elki.outlier.OutlierAlgorithm
    public class TrivialGeneratedOutlier
extends java.lang.Object
implements elki.outlier.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
