黎曼流形上的凸优化的新框架

作者 PulseAugur 编辑部 · [1 个来源] · 2026-09-29 04:00

研究人员开发了一个黎曼流形上的凸优化的新框架，引入了特定于收缩的凸集和基于收缩的梯度投影算法的概念。该框架扩展了标准的梯度投影算法，并包括了各种步长规则的收敛性证明。该方法已应用于加权低秩逼近，并在图像补全任务上进行了数值验证。 AI

流形上的基于回撤的梯度投影算法

arXiv:2609.30885v1 Announce Type: cross Abstract: We introduce a framework for retraction-based convex optimization on Riemannian manifolds, which includes a notion of retraction-specific convex sets and retraction-based gradient projection algorithms. The standard theory of grad…
