New models L-GRACE and L-BGRL advance graph link prediction

Researchers have adapted instance discrimination models, typically used for self-supervised learning in computer vision, for link prediction tasks in graph domains. Their evaluation showed that augmentation strategies significantly impact performance, similar to image-based methods. The study introduces two novel models, L-GRACE and L-BGRL, which focus on link representations rather than node representations, achieving state-of-the-art results, particularly on unattributed graphs.
