Thanks to the rise of big data and the rapid improvement of computing power, machine learning technology has experienced revolutionary development in recent years. Machine learning tasks such as image classification, speech recognition, and natural language processing all process Euclidean data with a certain size, dimension, and ordered arrangement. However, in many real-world scenarios, data are represented by complex non-Euclidean data (e.g., graphs). These graphs contain not only data but also dependencies between data, such as social networks, protein molecular structures, customer data in e-commerce platforms, etc. The increase in data complexity has brought serious challenges to traditional machine learning algorithm design and implementation technology. In this context, many new graph-based machine learning algorithms or graph neural networks (GNN) are constantly emerging in academia and industry.
