一种计算时态网络中节点通过因果路径的可通性的方法

A method to compute the communicability of nodes through causal paths in temporal networks

Agostino Funel

摘要:

我们提出了一种方法,旨在计算通过因果路径的时间网络中的节点的可通信性(广播和接收)。该方法考虑了网络快照邻接矩阵按时间顺序排列的乘积的所有可能组合,并通过阻尼过程有利于具有高通信效率的路径。我们将该方法应用于四个真实世界的面对面的人类接触网络,并确定具有高通信能力的节点。通过研究一种流行病在网络中的传播,证明了该方法的准确性,使用的模型是不可预测的感染-恢复。我们发现,如果一个节点与高广播被选为感染的爆发的起源,那么流行病传播早期,而它被延迟和抑制,如果感染的起源是一个节点与低广播。如果时间箭头颠倒,则接收节点可以被视为广播者。

英文摘要:

We present a method aimed to compute the communicability (broadcast and receive) of nodes through causal paths in temporal networks. The method considers all possible combinations of chronologically ordered products of adjacency matrices of the network snapshots and by means of a damping procedure favors the paths that have high communication efficiency. We apply the method to four real-world networks of face-to-face human contacts and identify the nodes with high communicability. The accuracy of the method is proved by studying the spread of an epidemic in the networks using the susceptible-infected-recovered model. We show that if a node with high broadcast is chosen as the origin of the outbreak of infection then the epidemic spreads early while it is delayed and inhibited if the origin of infection is a node with low broadcast. Receiving nodes can be treated as broadcasters if the arrow of time is reversed.
