Group ICA for identifying biomarkers in schizophrenia: 'Adaptive' networks via spatially constrained ICA show more sensitivity to group differences than spatio-temporal regression.

The results indicate a clear trend toward higher classification performance using GIG-ICA estimated networks in predicting independent data. 3.3 Comparison results of the functional network connectivity In addition to the statistical analysis and classification on the subject-level spatially independent networks, we also examined the differences in FNC estimated by GIG-ICA and STR.
