What the literature leaves open
The complexity of characterizing the network system's behavior due to the emergent behaviors that cannot be explained by examining the system's units individually or in pairs. The difficulty in disentangling the joint mutual information between the target and the pair of sources into non-negative information terms indicative of the unique, redundant, and synergistic contributions of the sources to the target variable. The need for a framework to investigate how pairs of signals contribute individually and jointly to determine the overall state of the network.
