Navigating Potholes with Geometry-Aware Sharpness Minimization
Simon Dufort-Labbé, Mehrab Hamidi, Razvan Pascanu +3
Sharpness-aware minimization (SAM) encourages flat minima by perturbing parameters along directions of high loss curvature, but treats all parameter directions uniformly, ignoring…

Layerwise LQR for Geometry-Aware Optimization of Deep Networks
Simon Dufort-Labbé, Pierre-Luc Bacon, Razvan Pascanu +2
Geometry-aware optimizers such as Newton and natural gradient can improve conditioning in deep learning, but scalable variants such as K-FAC, Shampoo, and related preconditioners u…
