Cost-Sensitive Radial Basis Function Neural Network Classifier for Software Defect Prediction

Table 4

Confusion matrix.

	Predicted as defective module	Predicted as nondefective module
Observed as defective module	True positive; (TP)	False negative; (FN)
Observed as nondefective module	False positive; (FP)	True negative; (TN)

True positive: correctly classified as defective module.
True negative: correctly classified as nondefective module.
False positive: classifies nondefective module as defective module.
False negative: classifies defective module as nondefective module.
