Support vector classification is applied to predict disease state (MDD) from resting state functional connectivity. Additionally two feature selection methods are proposed that score features based on reliability. The resulting classifier was able to distinguish MDD from controls 100% of the time. The two reliability based feature selection algorithms outperform t-test filter and recursive feature elimination methods.
