Global explainability of BPE classification: For each BPE class, the most important radiomic feature types are depicted: the vector length is color-coded in the 1st heatmap, and the corresponding orientation values are color-coded in the 2nd heatmap. The white places in the diagrams correspond to vector length values below the 75th percentile per BPE class, with the corresponding change values also indicated in white. The color scale is the same as in Figure 3e.
