摘要:

动态通信网络(DCN)描述了各种通信节点之间随时间的交互,作为数据源被广泛应用于大数据应用中。随着通信节点数量的增加和时间段的累积,每个节点在给定时间段内仅与少数节点进行交互,DCN可以由高维稀疏(HDS)张量表示。为了从DCN中的HDS张量中提取丰富的行为模式,本文提出了一种自适应时间依赖张量低秩表示(ATT)模型。它采用三重方法:a)设计一种时间依赖方法来重建时间特征矩阵,从而通过捕获时间模式来精确表示数据;b)通过差分进化算法(DEA)实现模型的超参数自适应,以避免繁琐的超参数调整;c)对模型参数采用非负学习方案,以有效处理HDS数据中固有的非负性。在四个真实世界DCN上的实验结果表明,所提出的ATT模型在预测误差和收敛轮数方面均显著优于几种最先进的模型。

英文摘要:

The Dynamic Communication Network (DCN) describes the interactions over time among various communication nodes, and it is widely used in Big-data applications as a data source. As the number of communication nodes increases and temporal slots accumulate, each node interacts in with only a few nodes in a given temporal slot, the DCN can be represented by an High-Dimensional Sparse (HDS) tensor. In order to extract rich behavioral patterns from an HDS tensor in DCN, this paper proposes an Adaptive Temporal-dependent Tensor low-rank representation (ATT) model. It adopts a three-fold approach: a) designing a temporal-dependent method to reconstruct temporal feature matrix, thereby precisely represent the data by capturing the temporal patterns; b) achieving hyper-parameters adaptation of the model via the Differential Evolutionary Algorithms (DEA) to avoid tedious hyper-parameters tuning; c) employing nonnegative learning schemes for the model parameters to effectively handle an the nonnegativity inherent in HDS data. The experimental results on four real-world DCNs demonstrate that the proposed ATT model significantly outperforms several state-of-the-art models in both prediction errors and convergence rounds.
