摘 要：

Recent years have seen a significantly growing amount of interests in graph neural networks (GNNs), especially on efforts devoted to developing more effective GNNs for node classification, graph classification, and graph generation. However, there are relatively less studies on other important topics such as graph-based encoder-decoder, deep graph matching, and deep graph learning. In the first part of the talk, I will introduce a Graph2Seq neural network framework, a novel attention-based encoder-decoder architecture for graph-to-sequence learning, and then talk about how to apply this model in different NLP tasks. In the second part of the talk, I will introduce a Hierarchical Graph Matching Network (HGMN) for computing the graph similarity between any pair of graph-structured objects. Our model jointly learns graph representations and a graph matching metric function for computing graph similarity in an end-to-end fashion. In the third part of the talk, I will introduce an end-to-end graph learning framework, namely Iterative Deep Graph Learning (IDGL), for jointly learning graph structure and graph embeddings simultaneously.
