The Construction of Support Vector Machine Classifier Using the Firefly Algorithm

Table 6

Performance indices for the firefly-SVM based and LIBSVM based OAA-FSVM.

Measures	Firefly-SVM based OAA-FSVM	LIBSVM based OAA-FSVM
Accuracy (%)	92.5	89.1
Sensitivity (%)	96.6	90.0
Specificity (%)	87.1	86.0
Youden’s index^* (%)	83.7	76.0
-score	95.9	92.6

Youden’s index = Sensitivity + Specificity – 1.
