Knowledge Distillation on Graphs: A Survey

Tian, Yijun, Pei, Shichao, Zhang, Xiangliang et al.

Understand

Graph Neural Networks (GNNs) have attracted tremendous attention by demonstrating their capability to handle graph data.

  • However, they are difficult to be deployed in resource-limited devices due to model sizes and scalability constraints imposed by the multi-hop data dependency.
  • In addition, real-world graphs usually possess complex structural information and features.
  • Therefore, to improve the applicability of GNNs and fully encode the complicated topological information, knowledge distillation on graphs (KDG) has been introduced to build a smaller yet effective model and exploit more knowledge from data, leading to model compression and performance improvement.
