Stability and Generalization of Graph Convolutional Neural Networks

Verma, Saurabh, Zhang, Zhi-Li

Understand

Inspired by convolutional neural networks on 1D and 2D data, graph convolutional neural networks (GCNNs) have been developed for various learning tasks on graph data, and have shown superior performance on real-world datasets.

  • Despite their success, there is a dearth of theoretical explorations of GCNN models such as their generalization properties.
  • In this paper, we take a first step towards developing a deeper theoretical understanding of GCNN models by analyzing the stability of single-layer GCNN models and deriving their generalization guarantees in a semi-supervised graph learning setting.
  • In particular, we show that the algorithmic stability of a GCNN model depends upon the largest absolute eigenvalue of its graph convolution filter.
