The components obtained from the scICA procedure Neuromark are shown in different colors. Each map shows the components belonging to a particular subdomains i.e., networks of brain. The 7 subdomains include: default mode network (DMN), visual (VIS), auditory (AU), cognitive control (CC), sensorimotor (SM), cerebellar (CB) and sub-cortical (SC). subdomain interaction (SDI) features built using these subdomains and components were used as input to the multi-branch MLP architecture optimized for variable branch-depth by the TPE algorithm. The SDI features are comprised of functional connectivity (static time-series correlation) between pairs of components belonging the same subdomain (intra-network connections) or different subdomains (inter-network conenctions). The 7 subdomains shown above lead to the creation of 28 SDIs, with 7C2 = 21 corresponding to the inter-network connections (Eg. DMN-VIS) and 7 corresponding to the intra-network connections (Eg. DMN-DMN).
