Table 2 Validation parameters
From: Fundus images analysis using deep features for detection of exudates, hemorrhages and microaneurysms
Parameter | Equation |
|---|---|
Accuracy | \( \frac{\mathrm{TP}+\mathrm{TN}}{\mathrm{TP}+\mathrm{TN}+\mathrm{FP}+\mathrm{FN}} \) |
Error rate | \( \frac{\mathrm{FP}+\mathrm{FN}}{\mathrm{TP}+\mathrm{TN}+\mathrm{FP}+\mathrm{FN}} \) |
Positive predict value (PPV) | \( \frac{\mathrm{TP}}{\mathrm{TP}+\mathrm{FP}} \) |
Sensitivity | \( \frac{\mathrm{TP}}{\mathrm{TP}+\mathrm{FN}} \) |
Specificity | \( \frac{\mathrm{TN}}{\mathrm{TN}+\mathrm{FP}} \) |
