本文研究了用时间序列数据估计离散时间网络病毒传播模型的参数。我们探讨了多种挑战对估计过程的影响,包括系统噪声、缺失数据、时变网络结构和测量的量化。我们还演示了如何很好地通过同构模型参数捕获异构模型。我们利用正在进行的2019年新型冠状病毒(2019- ncov)疫情收集的最新数据进一步说明了这些挑战,激励了未来的工作。
In this paper we investigate estimating the parameters of a discrete time networked virus spread model from time series data. We explore the effect of multiple challenges on the estimation process including system noise, missing data, time-varying network structure, and quantization of the measurements. We also demonstrate how well a heterogeneous model can be captured by homogeneous model parameters. We further illustrate these challenges by employing recent data collected from the ongoing 2019 novel coronavirus (2019-nCoV) outbreak, motivating future work.
