Adaptive Cross-stitch Graph Convolutional Networks

Abstract

Graph convolutional networks (GCN) have been widely used in processing graphs and networks data. However, some recent research experiments show that the existing graph convolutional networks have isseus when integrating node features and topology structure. In order to remedy the weakness, we propose a new GCN architecture. Firstly, the proposed architecture introduces the cross-stitch networks into GCN with improved cross-stitch units. Cross-stitch networks spread information/knowledge between node features and topology structure, and obtains consistent learned representation by integrating information of node features and topology structure at the same time. Therefore, the proposed model can capture various channel information in all images through multiple channels. Secondly, an attention mechanism is to further extract the most relevant information between channel embeddings. Experiments on six benchmark datasets shows that our method outperforms all comparison methods on different evaluation indicators.
