Graph Optimized Convolutional Networks

by   Bo Jiang, et al.
Anhui University

Graph Convolutional Networks (GCNs) have been widely studied for graph data representation and learning tasks. Existing GCNs generally use a fixed single graph which may lead to weak suboptimal for data representation/learning and are also hard to deal with multiple graphs. To address these issues, we propose a novel Graph Optimized Convolutional Network (GOCN) for graph data representation and learning. Our GOCN is motivated based on our re-interpretation of graph convolution from a regularization/optimization framework. The core idea of GOCN is to formulate graph optimization and graph convolutional representation into a unified framework and thus conducts both of them cooperatively to boost their respective performance in GCN learning scheme. Moreover, based on the proposed unified graph optimization-convolution framework, we propose a novel Multiple Graph Optimized Convolutional Network (M-GOCN) to naturally address the data with multiple graphs. Experimental results demonstrate the effectiveness and benefit of the proposed GOCN and M-GOCN.
