Fig. 3

Discriminative patterns (arbitrary units) between ALS and PP determined by PCA-LR (a), PCA-SVM (b), and SVM (c). The values in each voxel represent the weights of the contribution of the voxel for the classifier. Positive values (red) indicate regions of relative hypermetabolism of ALS patients compared to PP patients, whereas negative values (blue) correspond to relative hypometabolism of ALS patients compared to PP patients
