ARDiff: Anisotropic Residual Diffusion for Heterogeneous Graph Learning
Yong Chen, Li Li, Nannan Zong, Zhihui Liu, Song-Zhi Su
Abstract
Learning representations on graphs is foundational for many downstream tasks, and its synergy with diffusion models has emerged as a promising direction. However, diffusion-based methods for heterogeneous graphs remain underexplored, confronting two principal challenges: (1) The presence of noise and structural heterogeneity in graphs makes it challenging to accurately capture semantic transitions among diverse relation types. (2) The isotropic Gaussian noise used in forward diffusion fails to reflect graphs
