arXiv:2511.01938v3 Announce Type: replace Abstract: Grokking is a puzzling phenomenon in neural networks where full generalization occurs only after a substantial delay following the complete memorization of the training data. Previous research has linked this delayed generalization to representation learning driven by weight decay, but the precise underlying dynamics remain elusive. In this paper, we argue that post-memorization learning can be understood through the lens of constrained optimization: gradient descent effectively minimizes the weight norm on the zero-loss manifold.

This research provides a theoretical framework for understanding 'grokking', a persistent puzzle in AI development, at a time when deep learning models are becoming increasingly complex and critical. The paper is published in 2026, suggesting ongoing efforts to demystify core AI phenomena.
A deeper theoretical understanding of how neural networks generalize, especially phenomena like grokking, is crucial for developing more reliable, efficient, and interpretable AI systems. This knowledge can lead to breakthroughs in training methodologies and AI capabilities.
This work shifts the understanding of post-memorization learning towards a constrained optimization view, offering a new lens for debugging and optimizing neural network training dynamics. It provides a formal basis for empirical observations.
