Self-Supervised Learning with Gaussian Processes

Summary

The article presents Gaussian Process Self-Supervised Learning (GPSSL), a method that enhances self-supervised learning by leveraging Gaussian processes to impose priors on representations. This approach addresses the challenges of generating similar observation pairs and incorporates uncertainty quantification, which is often overlooked in traditional self-supervised methods. The authors demonstrate that GPSSL not only improves accuracy in classification and regression tasks but also provides better uncertainty management compared to existing techniques. The paper situates GPSSL within the broader context of kernel PCA and VICReg, highlighting its unique ability to propagate posterior uncertainties to downstream applications.
