Abstract

Spreading processes on networks (graphs) have become ubiquitous in modern society with prominent examples such as infections, rumors, excitations, contaminations, or disturbances. Finding the source of such processes based on observations is important and difficult. We abstract the problem mathematically as an optimization problem on graphs. For the deterministic setting we make connections to the metric dimension of a graph and introduce the concept of spread resolving sets. For the stochastic setting we propose a new algorithm combining parameter estimation and experimental design. We discuss well-posedness of the algorithm and show encouraging numerical results on a benchmark library.

图上的源检测

网络(图)上的传播过程在现代社会中无处不在，例如感染、谣言、兴奋、污染或干扰。根据观察发现这些过程的来源是重要而困难的。我们将这个问题抽象为图上的最优化问题。对于确定性集，我们与图的度量维建立联系，并引入扩展解析集的概念。对于随机设置，我们提出了一种结合参数估计和实验设计的新算法。我们讨论了该算法的适定性，并在一个基准库上展示了令人鼓舞的数值结果。
