Table 5 Classification accuracy (Q3) for structurally ambivalent residues. Average accuracy as measured by Q3 of 3-class categorical prediction of residues that have a structural ambivalence equal to or exceeding an entropy of 0.0 (all residues), 0.3 and 0.5. "CV": average (standard error) of five randomized repeats of 10-fold cross-validation on the training set (set-174). "test": average error on the test dataset (set-286).
