5. 争议的高潮——"scale-free networks are rare" 回顾前述的有关power-law拟合的技术手段的进步,从log-log坐标系下的线性拟合,到MLE估计+KS检验,再到对最优估计区间的估计,再到对其余的类power-law分布的估计,再到借助对数似然比来比较不同拟合分布哪个更契合实际数据,前人发展了一整套针对“网络度分布是否符...

A central claim in modern network science is that real-world networks are typically "scale free," meaning that the fraction of nodes with degree follows a power law, decaying like , often with . However, empirical evidence for this belief derives from a relatively small number of real-world ...

Are scale-free networks rare or universal? Important or not? We present the recent research about degree distributions of networks. This is a controversial topic, but, we argue, with some adjustments of the terminology, it does not have to be....
Scale-free networks are networks with a scale-free degree distribution, i.e., where the distribution of the number of links per node is a power-law, p(k)=ck -λ . We review results for the properties of such networks, emphasizing the structural propertie
In this paper I propose a novel method to model real online social networks where the growing scale-free networks have tunable clustering coefficient independently of the average degree and the exponent of the degree distribution. Models based on purely
The participation and response rates for the survey are given in Table 1. The networks included not only participants of the survey, but also non-participants recalled by the survey respondents, e.g., team members who did not participate, members of other teams, or those in supporting roles....
Recently, the term AI, particularly, has renewedly received widespread attention and describes techniques from computer science that gather many different concepts like machine learning, deep learning or neural networks, which are the basis of autonomous functionality and pervasive implementation. As a con...
The dimensions of what would have been a significant initial response to the pandemic are broadly emphasising health, having a global understanding, recognising competencies, not losing control and prioritising trust. These gender-neutral and style-free dimensions could form the dimensions of an “...
