Graph Barlow Twins: A self-supervised representation learning framework for graphs

Bielak, Piotr, Kajdanowicz, Tomasz, Chawla, Nitesh V.

Understand

The self-supervised learning (SSL) paradigm is an essential exploration area, which tries to eliminate the need for expensive data labeling.

  • Despite the great success of SSL methods in computer vision and natural language processing, most of them employ contrastive learning objectives that require negative samples, which are hard to define.
  • This becomes even more challenging in the case of graphs and is a bottleneck for achieving robust representations.
  • To overcome such limitations, we propose a framework for self-supervised graph representation learning - Graph Barlow Twins, which utilizes a cross-correlation-based loss function instead of negative samples.
