The content discusses the challenges of class imbalance in graph data and introduces VIGraph as a solution. It delves into the shortcomings of existing methods, particularly in constructing imbalanced graphs. VIGraph relies on Variational Graph Autoencoder (VGAE) and introduces comprehensive training strategies to generate high-quality nodes for minority classes. Extensive experiments demonstrate the superiority and generality of VIGraph.
