WebOct 6, 2024 · The graphlet degree distribution is one of the metrics to check the similarity between two networks. In a network, the distribution of a 2-node graphlet is the standard degree distribution, which is just one among the 30 graphlet distributions. Thus, the graphlet-based method is more general and provides a more in-depth examination of … WebApr 1, 2024 · Graphlets are used to provide node-level subgraph metrics and enable the generalisation of the notion of degree from the count of the number of edges a node has to the number of graphlets that it touches: …
WebFeb 2, 2016 · Given a graph G i from time window i, we count the occurrences of all graphlets up to size k, and store these graphlet counts in a graphlet degree vector, denoted g i. See Figure 1 for an example graph G i. with graphlet degree vector. g i. The notion of graphlets is easily extended to include colored vertices and edges as well as … WebAug 26, 2024 · The Graphlet Degree Vector (GDV) of a particular node is thus defined as a vector of the frequencies of 73 orbits. GDV, or sometimes normalised GDV, has been widely applied in various domains and has become a standard structural feature when measuring the similarities and differences between nodes [ 15 – 17 ].
