In this paper, researchers propose a new approach to graph contrastive learning (GCL) that focuses on efficiently learning edge features. The method, called AugmentationFree Edge Contrastive Learning (AFECL), consists of two parts: an edge feature generation method and an edge contrastive learning scheme. AFECL outperforms state-of-the-art GCL methods and even some supervised graph neural networks (GNNs) in link prediction and semi-supervised node classification tasks, achieving state-of-the-art performance on extremely scarce labels.

Graph contrastive learning is a type of machine learning that helps computers understand patterns in graphs. Graphs are like maps with nodes connected by edges. GCL works by teaching the computer to recognize similar patterns between different parts of the graph. The problem is that most GCL methods don’t pay much attention to the edges themselves, just using them as extra information to help learn about the nodes. This new approach focuses on learning from edges and uses a special way to generate features for each edge. The researchers tested this method and found it worked really well, even better than some other approaches that need more information.
