二进制结点元数据混合模式的网络约束

Network constraints on the mixing patterns of binary node metadata

Matteo Cinelli, Leto Peel, Antonio Iovanella, Jean-Charles Delvenne

摘要:

我们考虑了网络约束的边界上的互联性系数,它衡量的趋势,具有相同的属性值的节点互连。相关系数是跨网络边的节点属性值的皮尔逊相关系数,范围在-1到1之间。在这里,我们专注于二进制节点属性的可重性,并表明网络的属性,如度分布和每个属性值的节点数的地方限制可重性系数的可达到的值。我们探讨了在三个不同的空间,即,合奏的图形配置和节点属性分配,是有效的一组给定的网络约束的可追溯性。我们提供了获得这些空间的可拓性的极值上的界限的手段。最后,我们证明,在某些条件下的网络约束严重限制的最大值和最小值的反导性,这可能会出现问题,我们如何解释反导性系数。

英文摘要:

We consider the network constraints on the bounds of the assortativity coefficient, which measures the tendency of nodes with the same attribute values to be interconnected. The assortativity coefficient is the Pearson's correlation coefficient of node attribute values across network edges and ranges between -1 and 1. We focus here on the assortativity of binary node attributes and show that properties of the network, such as degree distribution and the number of nodes with each attribute value place constraints upon the attainable values of the assortativity coefficient. We explore the assortativity in three different spaces, that is, ensembles of graph configurations and node-attribute assignments that are valid for a given set of network constraints. We provide means for obtaining bounds on the extremal values of assortativity for each of these spaces. Finally, we demonstrate that under certain conditions the network constraints severely limit the maximum and minimum values of assortativity, which may present issues in how we interpret the assortativity coefficient.
