属性辅助异构图嵌入方法旨在对复杂结构和多个属性进行编码,以学习节点嵌入。与直接融合邻居属性更新节点嵌入的图神经网络(graph neural network, GNNs)不同,由于节点和边的类型不同,HGNNs需要克服属性的异质性,设计有效的融合方法来利用邻居信息,这带来了更多的挑战。在本节中,我们将异构网络表示分为无监督和半监督。
Existing survey papers of heterogeneous graph representation learning summarize all possible embedding techniques for graphs and make insufficient analysis for deep neural network models. To tackle this issue, in this paper, we systematically summarize and analyze existing heterogeneous graph neural networks ...
To study a general heterogeneous graph embedding model framework, we explore how to generate node embeddings in heterogeneous graphs by a graph neural network without using a meta-path. However, it is not easy to generate node embeddings in heterogeneous graphs by graph neural networks without ...
