其实Google的PageRank和KatzCentrality都是EigenCentrality的变形。 EigenCentrality的基本思想跟google是一样的,都是认为与得分(centrality)高的点相连的点更加重要。EigenCentrality就是用图的邻接矩阵来计算EigenCentrality(engenvector centrality, 特征向量中心度)。具体的公式和推到可以参考上面给出的维基百科链接,代码实现...
首先我们需要简化G,简化为G_C,叫做degeneracy core,就是简化版的G,其中所有node的core number都是G中最大的。而我们的最佳传播者就在degeneracy core的正中心而eigenvector centrality(x(v))就是用来计算node到底有多中心。 eigenvector centralityforG_c中所有的node(v):v的centrality,也即x(v)=1/G_c中node...
Eigenvector centrality introduces a nuanced perspective by considering not only the quantity of connections but also the quality of those connections. A node's eigenvector centrality score is influenced by its connections to other highly influential nodes. In other words, a node connected to nodes w...
Specifically, the use of eigenvector centrality afforded a more accurate weighting of the variables for each complex. Because off-system situations were predominant in several game complexes, i.e.: Setting Condition C in Complex I (0.36), Complex II (0.55), Complex III (0.80) and Complex V ...
To identify global regulators of the GRN, we filtered the global GRN for co-expression module membership, and calculated network eigenvector centrality for each gene in a given GRN subnetwork. While these genes may not have a direct role in the biological activity of the co-expression module, ...

The high-level contribution of this paper is a correlation coefficient analysis of the well-known centrality metrics (degree centrality, eigenvector centrality, betweenness centrality, closeness centrality, farness centrality and eccentricity) for network analysis studies on real-world network graphs represe...
