报告题目:Manifold Identification and Second-Order Algorithms for l1-Regularization on the Stiefel Manifold

报告内容:In this talk, we will discuss manifold identification for the l1-regularization problem on the Stiefel manifold. First, we will demonstrate that the intersection of the identified manifold with the Stiefel-like manifold forms a submanifold. Building on this, we will propose a novel second-order retraction-based algorithm specifically designed for the intersected submanifold. Numerical experiments confirm that the new algorithm exhibits superlinear convergence and outperforms existing methods.
