New theory advances self-supervised pre-training analysis

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a new asymptotic theory for self-supervised pre-training using two-stage M-estimation. This approach addresses the challenge of group symmetries inherent in representation learning by employing tools from Riemannian geometry. The theory precisely characterizes the limiting distribution of downstream test risk, offering improvements over existing methods in specific applications like spectral pre-training and factor models.

    On the Asymptotics of Self-Supervised Pre-training: Two-Stage M-Estimation and Representation Symmetry

    arXiv:2603.27631v2 Announce Type: replace-cross Abstract: Self-supervised pre-training, where large corpora of unlabeled data are used to learn representations for downstream fine-tuning, has become a cornerstone of modern machine learning. While a growing body of theoretical wor…
