Muon learns balanced solutions in matrix factorization without slow saddle-to-saddle dynamics
arXiv:2606.30509v1 Announce Type: new Abstract: Matrix factorization (i.e., problems of the form $\min_{\mathbf{P},\mathbf{Q}} \|\mathbf{M}^\star - \mathbf{P}^\top\mathbf{Q}\|_\mathrm{F}^2$) is a minimal learning problem that exhibits both nonlinear parameter dynamics and representation learning. In this setting, we study how parameter trajectories under the Muon optimizer differ from those of gradient descent. We identify three main dynamical differences: 1) Muon avoids the slow saddle-to-saddle dynamics from small initialization. Muon instead learns all the top modes of $\mathbf{M}^\star$ at
The paper was just published on arXiv, indicating a new development in optimization algorithms for machine learning, specifically addressing bottlenecks in matrix factorization.
Improved optimization techniques can significantly enhance the efficiency and performance of AI models, particularly in foundational tasks like representation learning, leading to faster training and potentially more robust outcomes.
Traditional gradient descent's slow saddle-to-saddle dynamics in matrix factorization can be circumvented, potentially accelerating the training and learning processes in various AI applications.
