Gradient Descent with Large Step Size Restores Symmetry in Deep Linear Networks with Multi-Pathway

Hee-Sung Kim, Sungyoon Lee

ICML, 2026

Large-step gradient descent at the Edge of Stability overrides the winner-takes-all architectural bias of multi-pathway deep linear networks, restoring shared representations across parallel pathways.

Inconsistency-Aware Minimization: Improving Generalization with Unlabeled Data

Hee-Sung Kim, Hyeonseong Kim, Sungyoon Lee

ICML, 2026

We recover SAM’s flat-minima bias from unlabeled data alone by regularizing local inconsistency, enabling flat-minima methods for semi- and self-supervised learning.
