In recent years, graph neural networks (GNN) have succeeded in many structural data analyses, including information retrieval, recommendation system, and social network analysis. Although the first-order graph convolutional networks are initially designed for single-view node-level representation learning, the graph-level analysis using GNNs applies according to recent studies, e.g., the shared structures can be learned from single-view graph data. The dissertation focuses on the efficient and robust graph-level representation learning using GNNs. Several effective methods are proposed to address the critical problems in graph representation learning, including over-smoothing, graph structural difference, and fast training. The application of graph representation learning on medical data is also studied, including new methods for single-view, multi-view, and unsupervised medical data analysis.
