TL;DR本文研究了基于 SIR 模型的信息源检测问题,在给定快照和网络拓扑的情况下,提出了一种基于样本路径和反向感染算法的信息源估计方法,并在实验中验证了其性能优于传统方法。
Abstract
This paper studies the problem of detecting the information source in a
network in which the spread of information follows the popular
Susceptible-Infected-Recovered (SIR) model. We assume all nodes in the network
are in the susceptible state initially except the information source which is
in the infected state. Susceptible nodes may then be infected by inf
