Statistical machine learning techniques are seeing
increased interest by the neuroimaging community.
Simultaneously clinicians and researchers are also
studying the functional connectivity patterns of brains
and how these relations might change in conditions like
Alzheimers disease or clinical depression. In this
study we investigate the performance of Gaussian process
classifiers to perform patient stratification from
functional connectivity patterns of brains at rest. The
majority of previous approaches to such problems have
focused on using support vector machines to perform
classification in this setting. Our results confirm that
Gaussian process classifiers form a promising direction
for future research.
