Table 2.

Formulae for model evaluation metrics.

Abbreviation Full Name or Calculation Formulas Serial Number
TP Positive samples predicted as positive by the model (correctly predicted positive samples) (1)
TN Negative samples predicted as negative by the model (correctly predicted negative samples) (2)
FP Negative samples predicted as positive by the model (positive samples with incorrect predictions) (3)
FN Positive samples predicted as negative by the model (negatively classified samples with incorrect predictions) (4)
Iou IoU=TPTP+FP+FN (5)
Accuracy Acc=TP+TNTP+TN+FP+FN (6)
F1-score F1=2*P*RP+R (7)
Precision P=TPTP+FP (8)
Recall R=TPTP+FN (9)
