WebJan 27, 2024 · Uniform homophily and differential homophily: When diff=FALSE , this term adds one network statistic to the model, which counts the number of edges (i,j) for which attr(i)==attr(j) . This is also called uniform homophily, because each group is assumed to have the same propensity for within-group ties. Webheterogeneity: [noun] the quality or state of consisting of dissimilar or diverse elements : the quality or state of being heterogeneous.

WebThe edge homophily ratio h = (u,v):(u,v)∈E∧yu=yv E is the fraction of edges in a graph which connect nodes that have the same class label, i.e., intra-class edges [21]. The homophily ratio h is a measure of the graph homophily level and we have h ∈ [0,1]. The larger the h value, the higher the homophily. 4 The Framework 4.1 Overview

Homophily of edges in graphs is typically defined based on the probability of edge connection between nodes within the same class. In accordance with intuition following (Zhu et al., 2024), the homophily ratio of edges is the fraction of edges in a graph that connect nodes with the same class label, described by: h= 1 E X (i,j)∈E ... chervonograd newsWebThat measure is called the edge homophily ratio.
