Class LabelEvaluationUtil.ROC

java.lang.Object
org.tribuo.classification.evaluation.LabelEvaluationUtil.ROC
Enclosing class:
LabelEvaluationUtil
public static class LabelEvaluationUtil.ROC extends Object
Stores the ROC curve as three arrays: the false positive rate, the true positive rate, and the thresholds associated with those rates.

By definition if both tpr and fpr are zero for the first value, the threshold is positive infinity.

Not yet a record, but it will be one day.
