Patterns within subnetworks. (a) The toy network in Fig. 2 with edge weights assigned. (b) The associated directed clique complex of the entire directed network in (a). (c) A 1-cycle consisting of the sum of four directed edges and a 2-cycle consisting of the sum of six 2-simplices embedded in the directed clique complex in (b). (d) A subnetwork obtained by including only edges of weight exactly 1. (e) The associated directed clique complex of the subnetwork in (c). (f) Three 1-cycles detected in the directed clique complex in (e)
