基于时序网络数据的流行病控制资源分配

Resource Allocation for Containing Epidemics from Temporal Network Data

Masaki Ogura, Junichi Harada

摘要:

研究了时间网络中的传染病传播问题。我们特别关注的问题,找到一个资源分配,以抑制流行病的感染,提供了一个经验的时间序列数据的节点之间的连接。虽然这个问题具有实际意义,但由于问题的计算复杂性,还不清楚经验时间序列数据如何告知我们的资源分配策略。在这个方向上,我们提出了一个计算效率的框架,找到一个资源分配,满足给定的预算约束,并实现了给定的控制性能。该框架是基于凸规划,而且,允许的性能指标来描述的一类广泛的泛函称为posynomials与非负指数。我们说明我们的理论结果使用的时间互动网络的数据在一所小学。

英文摘要:

We study the problem of containing epidemic spreading processes in temporal networks. We specifically focus on the problem of finding a resource allocation to suppress epidemic infection, provided that an empirical time-series data of connectivities between nodes is available. Although this problem is of practical relevance, it has not been clear how an empirical time-series data can inform our strategy of resource allocations, due to the computational complexity of the problem. In this direction, we present a computationally efficient framework for finding a resource allocation that satisfies a given budget constraint and achieves a given control performance. The framework is based on convex programming and, moreover, allows the performance measure to be described by a wide class of functionals called posynomials with nonnegative exponents. We illustrate our theoretical results using a data of temporal interaction networks within a primary school.
