org.tribuo.multilabel.evaluation.MultiLabelEvaluationImpl
All Implemented Interfaces:
com.oracle.labs.mlrg.olcut.provenance.Provenancable<EvaluationProvenance>, ClassifierEvaluation<MultiLabel>, Evaluation<MultiLabel>, MultiLabelEvaluation
public final class MultiLabelEvaluationImpl extends Object implements MultiLabelEvaluation
The implementation of a MultiLabelEvaluation using the default metrics.

The classification metrics consider labels independently.

    Method
    Description

    double
    balancedErrorRate()
    Returns the balanced error rate, i.e., the mean of the per label recalls.
    double
    confusion(MultiLabel predicted, MultiLabel truth)
    Returns the number of times label truth was predicted as label predicted.
    double
    f1(MultiLabel label)

    double
    fn()
    Returns the micro averaged number of false negatives.
    double
    fn(MultiLabel label)
    Returns the number of false negatives, i.e., the number of times the true label was incorrectly predicted as another label.
    double
    fp()
    Returns the micro average of the number of false positives across all the labels, i.e., the total number of false positives.
    double
    fp(MultiLabel label)
    Returns the number of false positives, i.e., the number of times this label was predicted but it was not the true label..
    ConfusionMatrix<MultiLabel>
    getConfusionMatrix()
    Returns the underlying confusion matrix.
    List<Prediction<MultiLabel>>
    getPredictions()
    Gets the predictions stored in this evaluation.
    EvaluationProvenance
    getProvenance()

    double
    precision(MultiLabel label)
    Returns the precision of this label, i.e., the number of true positives divided by the number of true positives plus false positives.
    double
    recall(MultiLabel label)
    Returns the recall of this label, i.e., the number of true positives divided by the number of true positives plus false negatives.
    double
    tn()
    Returns the total number of true negatives.
    double
    tn(MultiLabel label)
    Returns the number of true negatives for that label, i.e., the number of times it wasn't predicted, and was not the true label.
    String
    toString()
     
    double
    tp()
    Returns the micro average of the number of true positives across all the labels, i.e., the total number of true positives.
    double
    tp(MultiLabel label)
    Returns the number of true positives, i.e., the number of times the label was correctly predicted.
