我们调查了关于接触结构的错误信息对预测疾病爆发的能力的影响。我们的研究基于31个经验的时间网络,并调整了节点身份或联系人时间戳中的错误频率。我们发现,对于这两种传播情景,疫情规模和灭绝时间的最大错误预测都遵循作为错误频率的函数的延伸的指数收敛。此外,我们还确定了影响收敛参数的时间网络结构因素。
We investigate the impact of misinformation about the contact structure on the ability to predict disease outbreaks. We base our study on 31 empirical temporal networks and tune the frequencies in errors in the node identities or time stamps of contacts. We find that for both these spreading scenarios, the maximal misprediction of both the outbreak size and time to extinction follows an stretched exponential convergence as a function of the error frequency. We furthermore determine the temporal-network structural factors influencing the parameters of this convergence.
