'Graph Neural Networks are neural architectures specifically designed for graph-structured data, which have been receiving increasing attention recently and applied to different domains and applications. In this chapter, we focus on a fundamental task on graphs: node classification.We will give a detailed definition of node classification and also introduce some classical approaches such as label propagation. Afterwards, we will introduce a few representative architectures of graph neural networks for node classification. We will further point out the main difficulty— the oversmoothing problem—of training deep graph neural networks and present some latest advancement along this direction such as continuous graph neural networks.'
