Layer Imbalance Aware Multiplex Network Embedding

Kejia Chen, Yinchu Qiu, Zheng Liu

摘要:

多路网络嵌入是一种跨网络层联合学习节点低维表示的有效技术。然而,层之间的边缘的数量可以显著变化。这种数据不平衡将导致性能下降,特别是在稀疏层,由于学习偏差和其他层中的不相关或冲突的数据的不利影响。本文提出了一种层不平衡感知的多路复用网络嵌入(LIAMNE)方法,该方法基于目标层嵌入空间中节点的相似性对辅助层中的边缘进行欠采样,以实现边缘分布的平衡,并最小化与目标层不太相关的噪声关系。具有不同程度的层不平衡的真实世界数据集用于实验。结果表明,LIAMNE显着优于几个国家的最先进的复用网络嵌入方法在目标层的链接预测。同时,整个多路复用网络的全面代表性是不妥协的抽样方法,其性能评估的节点分类任务。

英文摘要:

Multiplex network embedding is an effective technique to jointly learn the low-dimensional representations of nodes across network layers. However, the number of edges among layers may vary significantly. This data imbalance will lead to performance degradation especially on the sparse layer due to learning bias and the adverse effects of irrelevant or conflicting data in other layers. In this paper, a Layer Imbalance Aware Multiplex Network Embedding (LIAMNE) method is proposed where the edges in auxiliary layers are under-sampled based on the node similarity in the embedding space of the target layer to achieve balanced edge distribution and to minimize noisy relations that are less relevant to the target layer. Real-world datasets with different degrees of layer imbalance are used for experimentation. The results demonstrate that LIAMNE significantly outperforms several state-of-the-art multiplex network embedding methods in link prediction on the target layer. Meantime, the comprehensive representation of the entire multiplex network is not compromised by the sampling method as evaluated by its performance on the node classification task.
