论文摘要

诚然,图形卷积网络(GCN)在图形数据集(例如社交网络,引用网络等)上取得了出色的结果。但是,通过梯度下降,使用数千次迭代来优化这些框架中的SoftMax作为决策层。此外,由于忽略了图节点的内部分布,决策层可能会导致半监视学习的性能不令人满意,而标签支持较少。为了解决引用的问题,我们提出了一个新的图形深模型,该模型具有用于图形挖掘的非梯度决策层。首先,流形学习与标签局部结构保存统一,以捕获节点的拓扑信息。此外,由于非梯度特性,封闭式解决方案被用作GCN的决策层。特别是,为该图模型设计了联合优化方法,该方法极大地加速了该模型的收敛性。最后,广泛的实验表明,与当前模型相比,所提出的模型已经达到了最先进的性能。

Admittedly, Graph Convolution Network (GCN) has achieved excellent results on graph datasets such as social networks, citation networks, etc. However, softmax used as the decision layer in these frameworks is generally optimized with thousands of iterations via gradient descent. Furthermore, due to ignoring the inner distribution of the graph nodes, the decision layer might lead to an unsatisfactory performance in semi-supervised learning with less label support. To address the referred issues, we propose a novel graph deep model with a non-gradient decision layer for graph mining. Firstly, manifold learning is unified with label local-structure preservation to capture the topological information of the nodes. Moreover, owing to the non-gradient property, closed-form solutions is achieved to be employed as the decision layer for GCN. Particularly, a joint optimization method is designed for this graph model, which extremely accelerates the convergence of the model. Finally, extensive experiments show that the proposed model has achieved state-of-the-art performance compared to the current models.
