Webedge to measure graph homophily level. H edge is defined as the proportion of inter-class edges over all edges. Follow-up works invent other criteria to measure graph ho-mophily level, including node homophily ratio H node (Pei et al.,2024) and class homophily H class (Lim et al.,2024). These works state that high and low homophily levels re- WebGenerally, the homophily degree of a graph can be measured by node homophily ratio [11]. Definition1 (Node homophily ratio) [11] It is the average ratio of same-class neighbor nodes to the total neighbor nodes in a graph.
