论文摘要
如今，必须处理多层网络上的传播并经常发现所述传播的来源可能是一项至关重要的任务，这并不少见。在本文中，我们通过最大似然方法解决了这个确切的问题，我们扩展到在多层图上进行操作。我们测试了我们的方法，以在合成网络上估算源位置，并概述其潜在的优势和局限性。我们还观察到了一些非平凡的，也许令人惊讶的现象，在这种现象中，人们观察到的越越好，结果越好，而以更多层的形式增加了问题的复杂性，实际上可以改善我们的性能。
Nowadays it is not uncommon to have to deal with dissemination on multi-layered networks and often finding the source of said propagation can be a crucial task. In this paper we tackle this exact problem with a maximum likelihood approach that we extend to be operational on multi-layered graphs. We test our method for source location estimation on synthetic networks and outline its potential strengths and limitations. We also observe some non-trivial and perhaps surprising phenomena where the more of the system one observes the worse the results become whereas increased problem complexity in the form of more layers can actually improve our performance.
