Graph assortativity
Weblation. In general, assortativity can be used as a tool measuring the association between any pair of vertex features. Let Xand Y be two quantitative features for all the vertices in a weighted and directed network G(V;E). Let (X i;Y i) be the two features for each ver-tex i2V. Our weighted and directed assortativity measure based on the sample ... WebJun 11, 2024 · The resulted multi-relational graph has an enhanced level of assortativity and, more importantly, preserves rich information from the original graph. We then propose to run GNNs on this computation graph and show that adaptively choosing between structure and proximity leads to improved performance under diverse mixing. Empirically, …

WebFeb 27, 2003 · We also propose several models of assortatively mixed networks, both analytic ones based on generating function methods, and numerical ones based on Monte Carlo graph generation techniques. We use these models to probe the properties of networks as their level of assortativity is varied.
