abstract = {Recent studies show that overlapping community structure is
an important feature of the brain functional network.
However, alterations in such overlapping community structure
in Alzheimer’s disease (AD) patients have not been
examined yet. In this study, we investigate the overlapping
community structure in AD by using resting-state functional
magnetic resonance imaging (rs-fMRI) data. The collective
sparse symmetric non-negative matrix factorization (cssNMF)
is adopted to detect the overlapping community structure.
Experimental results on 28 AD patients and 32 normal
controls (NCs) from the ADNI2 dataset show that the two
groups have remarkable differences in terms of the optimal
number of communities, the hierarchy of communities detected
at different scales, network functional segregation, and
nodal functional diversity. In particular, the
frontal-parietal and basal ganglia networks exhibit
significant differences between the two groups. A machine
learning framework proposed in this paper for AD detection
achieved an accuracy of $76.7\%$ when using the detected
community strengths of the frontal-parietal and basal
ganglia networks only as input features. These findings
provide novel insights into the understanding of
pathological changes in the brain functional network
organization of AD and show the potential of the community
structure-related features for AD detection.},
