论文摘要

复杂网络的大多数经验研究不会返回网络结构的直接无错误测量。相反,他们通常依赖于通常容易出错且不可靠的间接测量结果。经验网络科学中的一个基本问题是如何在这种不可靠的数据给定网络结构的最佳估计中进行最佳估计。在本文中,我们描述了一种完全贝叶斯的方法,用于以任何格式从观察数据重建网络,即使数据包含大量的测量误差以及该误差的性质和幅度何时未知。该方法是通过使用现实世界示例网络的教学案例研究引入的,并专门针对最少的技术输入允许直接,计算有效的实现。实施该方法的计算机代码已公开可用。

Most empirical studies of complex networks do not return direct, error-free measurements of network structure. Instead, they typically rely on indirect measurements that are often error-prone and unreliable. A fundamental problem in empirical network science is how to make the best possible estimates of network structure given such unreliable data. In this paper we describe a fully Bayesian method for reconstructing networks from observational data in any format, even when the data contain substantial measurement error and when the nature and magnitude of that error is unknown. The method is introduced through pedagogical case studies using real-world example networks, and specifically tailored to allow straightforward, computationally efficient implementation with a minimum of technical input. Computer code implementing the method is publicly available.
