WebMar 21, 2024 · Louvain’s algorithm aims at optimizing modularity. Modularity is a score between -0.5 and 1 which indicates the density of edges within communities with respect to edges outside communities [2]. The closer the modularity is to -0.5 implies non modular clustering and the closer it is to 1 implies fully modular clustering. Webty (Q) as Fine-tuned Q while the one based on Modularity Density (Qds) is referred to as Fine-tuned Qds. Finally, we evaluate the greedy algorithm of modularity max-imization (denoted as Greedy Q), Fine-tuned Q, and Fine-tuned Qds by using seven community quality metrics based on ground truth communities. These evaluations
Web当modularity这个度量被认可后,后续很多算法的思路就是如何找到一个partitioning的方法,使得modularity最大。 将community detection转化成了最优化的问题。 而因为查找全局最优的modularity是一个NP-hard问 … WebThe weights of the edges. It must be a positive numeric vector, NULL or NA. If it is NULL and the input graph has a ‘weight’ edge attribute, then that attribute will be used. If NULL and no such attribute is present, then the edges will have equal weights. Set this to NA if the graph was a ‘weight’ edge attribute, but you don't want to ...
WebApr 27, 2015 · A precise definition of the modularity from wikipedia: Modularity is the fraction of the edges that fall within the given groups minus the expected such fraction if edges were distributed at random. The value of the modularity lies in the range [−1/2,1). It is positive if the number of edges within groups exceeds the number expected on the ...
