多尺度链接预测

Multi-Scale Link Prediction

Donghyuk Shin, Si Si, Inderjit S. Dhillon

摘要:

由于社交网络(例如LiveJournal、Flickr和Facebook)的激增,社交网络的自动分析已经成为重要问题。这些社交网络的规模巨大,并继续快速增长。社会网络分析中的一个重要问题是邻近度估计,即推断不同用户的接近程度。链接预测又是邻近度估计的重要应用。然而,许多用于计算邻近度测量的方法具有高计算复杂性,并且因此对于大规模链接预测问题是禁止的。解决这个问题的一种方法是通过低秩近似来估计邻近度。然而,单个低秩近似可能不足以表示整个网络的行为。在本文中,我们提出了多尺度链接预测(MSLP),链接预测的框架,它可以处理大规模的网络。MSLP的基本思想是以有效的方式在多个尺度上构造网络的低秩近似。基于这种方法,MSLP将多个尺度的预测组合在一起,以做出稳健而准确的预测。在超过一百万节点的真实数据集上的实验结果表明,我们的方法具有优越的性能和可扩展性。

英文摘要:

The automated analysis of social networks has become an important problem due to the proliferation of social networks, such as LiveJournal, Flickr and Facebook. The scale of these social networks is massive and continues to grow rapidly. An important problem in social network analysis is proximity estimation that infers the closeness of different users. Link prediction, in turn, is an important application of proximity estimation. However, many methods for computing proximity measures have high computational complexity and are thus prohibitive for large-scale link prediction problems. One way to address this problem is to estimate proximity measures via low-rank approximation. However, a single low-rank approximation may not be sufficient to represent the behavior of the entire network. In this paper, we propose Multi-Scale Link Prediction (MSLP), a framework for link prediction, which can handle massive networks. The basis idea of MSLP is to construct low rank approximations of the network at multiple scales in an efficient manner. Based on this approach, MSLP combines predictions at multiple scales to make robust and accurate predictions. Experimental results on real-life datasets with more than a million nodes show the superior performance and scalability of our method.
