Figure 5.
The four plots present A C C, p M C I sensitivity, s M C I specificity and A U C in per cent against the number of regions from 100 to 1000. The A C C plot shows Schaefer decreasing initially and then rising with fluctuations. C Atlas and C Atlas plus generally increase, with fluctuations at higher region counts. The p M C I sensitivity plot shows Schaefer fluctuating across the region counts. C Atlas and C Atlas plus generally increase from lower initial levels and fluctuate at higher region counts. The s M C I specificity plot shows Schaefer decreasing sharply at lower region counts before increasing gradually. C Atlas and C Atlas plus generally increase with fluctuations. The A U C plot shows all three methods fluctuating. Schaefer falls sharply at lower region counts before generally increasing. C Atlas and C Atlas plus generally rise after early fluctuations. Horizontal reference lines represent L P B A 40 with 56 features and A A L with 120 features. Shaded bands surround the three plotted series.Performance of multiscale atlases on the sMCI versus pMCI classification task, with 95% confidence-interval bands from 100 repeats of fivefold cross-validation. LPBA40 and AAL are shown as horizontal baselines
