Illustration of how the functional connectivity matrix for the 53 components (53 × 53 in size) is divided into subdomain interactions (SDIs) that form the input to the branched Multilayer Perceptron (MLP) architecture. Each colored sub-matrix represents a certain SDI i.e., the set of functional connectivity values between components of a given pair of subdomains. The 7 subdomains include: default mode network (DMN), visual (VIS), auditory (AU), cognitive control (CC), sensorimotor (SM), cerebellar (CB) and sub-cortical (SC). A total of 28 SDIs, which are sub-matrices of the full functional connectivity matrix, are colored in different colors. Since the number of subdomains is 7, a total of 7C2 = 21 out of the 28 SDIs correspond to inter-network connections (e.g. DMN-VIS) while 7 correspond to intra-network connections (e.g. DMN-DMN).
