Table 4 The calculation formulas of evaluation indices
| Evaluation indices | Calculation formulas |
|---|---|
| Accuracy | \(Acc = \frac{TP + TN}{{TP + FN + FP + TN}}\) |
| Sensitivity | \(Sen = \frac{TP}{{TP + FN}}\) |
| Specificity | \(Spe = \frac{TN}{{FP + TN}}\) |
| Precision | \(\Pr e = \frac{TP}{{FP + TP}}\) |
| F1 score | \(F1 = \frac{2*\Pr e*Sen}{{\Pr e + Sen}}\) |
