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.
