2.1 Power-Law Degree Distribution 下面我们来看一下,Natural Graph这种图到底有什么特点,为什么大部分分布式处理系统性能都比较低效,PowerGraph在Natural Graph有如此好的性能。Natural Graphs的属性特点是满足密率度分布。下面我们来看下什么叫幂律度分布。 简单来说,幂律有两个通俗的解释,一个是“长尾”理论,只有...
的问题就是:现有的图数据,如社交网络、Web网页等都是一种Power-law幂律图的特征。所谓Power-law幂律图就是指在图数据中顶点的度数分配不均匀。有的图顶点的度数很高,有的顶点度数很低。并且...我们来看一下自然图到底有什么特征。 2.1Power-LawDegreeDistribution 下面我们来看一下,NaturalGraph这种图到底有什么...
The degree statistics of a random graph in our model is governed by the control parameter η stirring the pure exponential statistics for the degree distribution (at η=0, when the threshold value is changed each time a new edge is added to the graph) to a power law (at η=1, when ...
A random graph model for power law graphs - Aiello, Chung, et al. () Citation Context ...s prevalent in all kinds of real world networks. First popularized by the Preferential attachment model [4], power-law degree distributions has been hot topic in networks across different disciplines =...
4.2.1 Power-law degree distribution Degree distribution refers to the probability distribution of nodes degree in the whole network, which is denoted by P(k). In random networks, degree distribution is highly homogeneous since the existence of each edge is equiprobable. Unlike random networks, Bar...

A power law is a special mathematical relationship between two quantities in which one quantity varies as a power of the other. Numerous examples of power laws occur in nature, for example, the frequency of any word in a language is inversely proportional to its ranking in a frequency table....
