Chart of the top 20 relevant features with their importance scores
measured by Shapley additive explanations (SHAP) values. The feature
names are labeled as region of interest 1 (ROI1) and ROI2, representing
the whole tumor and the nonenhancing tumor (NET), necrosis (NCR), and
edema (ED) region of interests, respectively. glcm = gray-level
co-occurrence matrix, glszm = gray-level size zone matrix, log =
Laplacian of Gaussian, ROI = region of interest, wavelet-LH = wavelet
filtering with low-pass and high-pass filters, wavelet-LL = wavelet
filtering with low-pass filters.
