Jan 27, 2022 · Katz中心性是特征向量中心性的一个变体，它不仅考虑了邻居的中心性，而且包含了一个常数来考虑中心节点本身。 具体来说，节点 vi 的Katz中心性可以定义为： c k ( v i ) = α ∑ j = 1 N A i , j c k ( v j ) + β c_k (v_i)= {\alpha}\sum_ {j=1}^NA_ {i,j}c_k (v_j)+\beta ck(vi) = α j=1∑N Ai,j ck(vj)+β 式中， β 是一个常数。 一个图中所有节点的Katz中心性可以用矩阵形式表示为： I I I 表示单位矩阵。 值得注意的是，如果令. λ m a x {\lambda}_ {max} λmax 是邻接矩阵 A 的最大 …

文章介绍了图论和网络分析中的中心性指标，包括特征向量中心性、Katz中心性和PageRank。 特征向量中心性基于节点的邻居重要性，Katz中心性解决了有向图的问题，而PageRank则用于网页排序，考虑了节点的出度来调整影响。 这些概念在社交网络和信息检索中有广泛应用。 维基百科：在图论和网络分析中，中心性指标为图中相应网络位置的节点分配排名或数值。 中心性这一概念最初起源于 社交网络分析，因此很多衡量中心性的术语也反映了其社会学背景。 不同中心性 …

当考虑 有向图 时， 特征向量中心性 就产生了一个主要问题. 中心性仅通过出边传递，并且在某节点位于有向 非循环图 中（只进不出）等特殊情况下，中心性变为零. –这个节点可以有许多连通的边. 若要解决此问题，我们将向所有节点的中心性值添加 偏差项 \beta. C_ {Katz}\left ( v_ {i} \right)=\alpha \Sigma_ {j=1}^ {n}A_ {j,i}C_ {Katz}\left ( v_ {j} \right)+\beta 特征向量中心性.
