Major depressive disorder (MDD) requires study of brain functional
connectivity alterations for patients, which can be uncovered by resting-state
functional magnetic resonance imaging (rs-fMRI) data. We consider the problem
of identifying alterations of brain functional connectivity for a single MDD
patient. This is particularly difficult since the amount of data collected
during an fMRI scan is too limited to provide sufficient information for
individual analysis. Additionally, rs-fMRI data usually has the characteristics
of incompleteness, sparsity, variability, high dimensionality and high …
