用于社区发现的具有非负矩阵分解的深度图卷积神经网络

Deep graph convolution neural network with non-negative matrix factorization for community discovery

Shuliang Xu, Shenglan Liu, Lin Feng

摘要:

社区发现是图挖掘的一个重要任务。由于图数据的非结构性、高维性和稀疏性,很难得到合适的社区划分。提出了一种基于非负矩阵分解的深度图卷积神经网络(DGCN-NMF)用于社区发现。DGCN-NMF采用多个图卷积层来获得低维嵌入。在每一层中,最后一个输出和前一个输出的非负矩阵分解的结果被输入到当前层。输入图的社区划分可以通过端到端的方法输出。在实验数据集上对所提出的算法和比较算法进行了验证。实验结果表明,该算法优于比较算法的实验数据集。实验结果表明,DGCN-NMF是一种有效的社区发现算法。

英文摘要:

Community discovery is an important task for graph mining. Owing to the nonstructure, the high dimensionality, and the sparsity of graph data, it is not easy to obtain an appropriate community partition. In this paper, a deep graph convolution neural network with non-negative matrix factorization (DGCN-NMF) is proposed for community discovery. DGCN-NMF employs multiple graph convolution layers to obtain the low dimensional embedding. In each layer, the last output and the non-negative matrix factorization's results of the previous outputs are inputted into the current layer. The community partition of the inputted graph can be outputted by an end-to-end approach. The proposed algorithm and the comparison algorithms are conducted on the experimental data sets. The experimental results show that the proposed algorithm outperforms the comparison algorithms on the experimental data sets. The experimental results demonstrate that DGCN-NMF is an effective algorithm for community discovery.
