摘要:

大规模动态网络(LDNs)在互联网时代日益重要,然而这些网络的动态特性捕捉了网络结构的演化以及边权重随时间变化的方式,给数据分析和建模带来了独特挑战。张量隐因子分解(LFT)模型有助于为LDN实现高效的表示学习。但现有的LFT模型几乎都基于典型多元分解(CPF)。因此,本文提出一种基于张量环(TR)分解的模型,用于LDN的高效表示学习。具体而言,我们将单隐因子依赖、非负和乘法更新(SLF-NMU)原则融入TR分解模型,并分析了TR分解的特定偏置形式。在两个真实LDN上的实验研究表明,所提方法比现有模型取得了更高的精度。

英文摘要:

Large-scale Dynamic Networks (LDNs) are becoming increasingly important in the Internet age, yet the dynamic nature of these networks captures the evolution of the network structure and how edge weights change over time, posing unique challenges for data analysis and modeling. A Latent Factorization of Tensors (LFT) model facilitates efficient representation learning for a LDN. But the existing LFT models are almost based on Canonical Polyadic Factorization (CPF). Therefore, this work proposes a model based on Tensor Ring (TR) decomposition for efficient representation learning for a LDN. Specifically, we incorporate the principle of single latent factor-dependent, non-negative, and multiplicative update (SLF-NMU) into the TR decomposition model, and analyze the particular bias form of TR decomposition. Experimental studies on two real LDNs demonstrate that the propose method achieves higher accuracy than existing models.
