AUC histograms based on the comparison methods for the three classification tasks. (A) Classification performance of different methods for AD and NC in the ADNI cohort. (B) Classification performance of different methods for LMCI and EMCI in the ADNI cohort. (C) In the ADNI cohort, pMCI and sMCI were classified based on the AD vs. NC classifier. AUC, area under the curve; AGNN, attention-based graph neural network; GAT, graph attention network; AD, Alzheimer’s disease; NC, normal control; pMCI, progressive mild cognitive impairment; sMCI, stable mild cognitive impairment; LMCI, late mild cognitive impairment; EMCI, early mild cognitive impairment; ADNI, Alzheimer’s Disease Neuroimaging Initiative.
