Graph Convolutional Attention: A Spectral Perspective on Graph Denoising and Diffusion
This paper introduces Spectral Attention and Graph Convolutional Attention (GCA) for denoising graphs, which outperforms linear attention and provably utilizes the input graph spectrum.
DiPhon: Diffusion on Graphons for Scalable Graph Generation
This paper introduces DiPhon, a diffusion framework for size-scalable graph generation, using a continuous diffusion process on the graphon space and a discretized graph-level process.
