Receiver Operating Characteristic curves of three basic classifiers. The horizontal axis indicates the false positive rate and the vertical axis indicates the true positive rate. The diagonal line represents the pure opportunity line, which is considered the reference line. The AUC values of ResNet-18, Handcraft feature and Denoising Auto Encoder were 0.85, 0.72 and 0.74, respectively, which was considered significant for nodules classification. AUC, area under the curve.
