新的LLQR+SAM方法通过几何感知锐度最小化改进模型训练

研究人员开发了一种新的优化技术,称为LLQR+SAM,它通过整合损失景观的几何信息来增强锐度感知最小化(SAM)的有效性。该方法使用来自LLQR框架的学习预条件器来指导SAM的参数扰动,专注于局部尖锐但全局平坦的方向。该方法旨在更有效地导航复杂的损失景观,与单独使用SAM或LLQR相比,在视觉和序列建模任务上取得了更好的性能。 AI

影响 引入了一种新颖的优化技术,可能导致更有效的视觉和序列模型训练。

    利用几何感知锐度最小化来应对颠簸路面

    Sharpness-aware minimization (SAM) encourages flat minima by perturbing parameters along directions of high loss curvature, but treats all parameter directions uniformly, ignoring the underlying loss geometry. We introduce LLQR+SAM, which combines SAM with a learned preconditione…
