We compute the statistical difference of the learned connectivity matrices for OASIS ICA when predicting dementia, age and gender. The results show that the learned connectivity matrices are highly statistically different and SMN gets higher connectivity scores than DMN for dementia prediction whereas the opposite is seen for gender prediction.
