Figure 3. Receiver operator characteristics curves for different models.

Receiver operator characteristics curves for the response predictor model obtained based on QUS+QUS-Tex¹ (dotted line) and based on QUS + QUS-Tex¹ + QUS-Tex¹-Tex² (solid line) using FLD, SVM, and KNN classifiers. QUS: Quantitative ultrasound; FLD: Fisher’s linear discriminant; SVM: Support vector machine; KNN: k-nearest-neighbors; AUC: Area under curve.
