Augment with Care: Enhancing Graph Contrastive Learning with Selective Spectrum Perturbation

no code implementations20 Oct 2023 Kaiqi Yang, Haoyu Han, Wei Jin, Hui Liu

Existing augmentation views with perturbed graph structures are usually based on random topology corruption in the spatial domain; however, from perspectives of the spectral domain, this approach may be ineffective as it fails to pose tailored impacts on the information of different frequencies, thus weakening the agreement between the augmentation views.
