TPR^a

TP/(TP + FN)

FPR

FP/(FP + TN)

Precision^b

TP/(TP + FP)

Accuracy

(TP + TN)/(TP + TN + FP + FN)

F-score

2 × TPR × Precision/(TPR + Precision)

MCC

$\frac{TP\times TN-FP\times FN}{\sqrt{\left(TP+FP\right)\left(TP+FN\right)\left(TN+FP\right)\left(TN+FN\right)}}$

AUC

Area under the ROC curve
