Research paper questions grokking transition mechanism in neural networks

A new research paper explores the phenomenon of "grokking" in neural networks, where a model initially performs poorly but then rapidly improves its generalization ability after memorizing the training data. The study investigates whether this sharp transition is caused by a loss of normal hyperbolicity in the interpolation manifold, a concept from dynamical systems. Using a diagnostic tool based on the smallest nonzero singular value of the residual Jacobian, the researchers found that this value does not collapse during the transition, suggesting that the generalization improvement might be a smooth drift rather than a bifurcation event.
