The Girvan–Newman algorithm detects communities by progressively removing edges from the original network. The connected components of the remaining network are the communities. Instead of trying to construct a measure that tells us which edges are the most central to communities, the Girvan–Newman algorithm focuses on edges that are most likely "between" communities. Web25 apr. 2024 · The Girvan-Newman algorithm is the most widely used algorithm to evaluate the quality of a partition of a network. However, since its inception in 2002, there have been many algorithms that have...

Modularity (networks) - Wikipedia

Webmodularity #. modularity. #. modularity(G, communities, weight='weight', resolution=1) [source] #. Returns the modularity of the given partition of the graph. Modularity is defined in [1] as. Q = 1 2 m ∑ i j ( A i j − γ k i k j 2 m) δ ( c i, c j) where m is the number of edges, A is the adjacency matrix of G , k i is the degree of i, γ ... Modularity is a measure of the structure of networks or graphs which measures the strength of division of a network into modules (also called groups, clusters or communities). Networks with high modularity have dense connections between the nodes within modules but sparse connections between nodes in different modules. Modularity is often used in optimization methods for detecting comm… how trustworthy is msnbc
