English(EN) A Rod Flow Model for Adam at the Edge of Stability

新的杆流模型跟踪Adam优化器在稳定性边缘

作者 PulseAugur 编辑部 · [2 个来源] · 2026-05-07 18:21

研究人员开发了一种新的“杆流”模型，以更好地理解像Adam这样的自适应梯度优化方法在稳定性边缘的运行方式。该模型将之前关于梯度下降的工作扩展到包括基于动量的方法，将优化迭代视为一维“杆”。新框架准确地跟踪了包括Adam和RMSProp在内的八种不同优化器在各种机器学习架构上的离散迭代。 AI

影响为理解和潜在地提高机器学习中常用优化算法的稳定性提供了更准确的理论框架。

A Rod Flow Model for Adam at the Edge of Stability

Cohen et al. (arXiv:2207.14484) observed that adaptive gradient methods such as Adam operate at the edge of stability. While there has been significant work on continuous-time modeling of gradient descent at the edge of stability, extending these models to momentum methods remain…
