Figure 4. The influence of key model parameters for linear SVM and IBk classifiers.

Figure 4

(A) The classification performance of LibSVM (linear) classifier using different c. When using c=2-3, the best classification performance was achieved for both LGG and HGG (Accuracy/AUC = 0.945/0.945) as well as grade II, III, and IV (Accuracy/AUC = 0.961/0.971) gliomas classification. (B) The classification accuracy and AUC values of IBk classifiers using different K in KNN for LGG and HGG as well as grade II, III, IV gliomas classification, respectively.
