CompGCN
COMPOSITION-BASED MULTI-RELATIONAL GRAPH CONVOLUTIONAL NETWORKS
1 INTRODUCTION
原来的CNN, RNN等方法不能直接应用到graph上,因此最近GCN被提出来了。
但是初始的GCN方法主要集中与无向图,最近的针对有向图的方法类如R-GCN,存在over-parameterization问题。
there is a need for a framework which can utilize KG embedding techniques for learning task-specific node and relation embeddings.
COMPGCN addresses the shortcomings of previously proposed GCN models by jointly learning vector representations for both nodes and relations in the graph
