Performance measure Definition
TPRa TP/(TP + FN)
FPR FP/(FP + TN)
Precisionb TP/(TP + FP)
Accuracy (TP + TN)/(TP + TN + FP + FN)
F-score 2 × TPR × Precision/(TPR + Precision)
MCC T P × T N - F P × F N T P + F P T P + F N T N + F P T N + F N
AUC Area under the ROC curve
  1. aTrue Positive Rate is also known as Sensitivity or Recall.
  2. bPrecision is also known as Positive Predictive Value.
