SSFG: Stochastically Scaling Features and Gradients for Regularizing Graph Convolutional Networks

Zhang, Haimin, Xu, Min, Zhang, Guoqiang et al.

Understand

Graph convolutional networks have been successfully applied in various graph-based tasks.

  • In a typical graph convolutional layer, node features are updated by aggregating neighborhood information.
  • Repeatedly applying graph convolutions can cause the oversmoothing issue, i.e., node features at deep layers converge to similar values.
  • Previous studies have suggested that oversmoothing is one of the major issues that restrict the performance of graph convolutional networks.
