- All network models are based on Random Network, a growing network adaptation of the Erdős-Rényi random network (Erdős and Rényi 1960). We focus on three mechanisms: preferential attachment, homophily, and diversity (through adding inter-group edges). Starting from a Random Network and adding preferential attachment results in the BA model. Starting from a Random Network and adding homophily results in the Random Homophily model. Starting from a Random Network and adding both preferential attachment and homophily results in the Homophily BA model. Starting from Random Homophily and adding diversity results in the Diversified Homophily model. Starting from Homophily BA and adding diversity gives us Diversified Homophily BA model. In our study, we treat BA and Random Homophily as the variations of the Homophily BA model, and Diversified Homophily as a variation of the Diversified Homophily BA
