Sensitivity and specificity (TPR, TNR, FPR)
A binary evaluator's error rates against a reference: sensitivity (TPR) is the probability it accepts a true positive, specificity (TNR) the probability it rejects a true negative, and the false-positive rate FPR = 1 − TNR.
Also called: TPR, TNR, FPR, true-positive rate, false-positive rate
