Package elki.evaluation.outlier

Class OutlierROCCurve

  • All Implemented Interfaces:
    Evaluator, ResultProcessor
    public class OutlierROCCurve
extends java.lang.Object
implements Evaluator
    Compute a ROC curve to evaluate a ranking algorithm and compute the corresponding AUROC value.

    The parameter -AUROC.positive specifies the class label of "positive" hits.

    The nested algorithm -algorithm will be run, the result will be searched for an iterable or ordering result, which then is compared with the clustering obtained via the given class label.
