Geometric design of the tangent term in landing algorithms for orthogonality constraints

2025-07-21 · Florentin Goyens, P. -A. Absil, Florian Feppon arxiv

We propose a family a metrics over the set of full-rank $n\times p$ real matrices, and apply them to the landing framework for optimization under orthogonality constraints. The family of metrics we propose is a natural extension of the $β$-metric, defined on the Stiefel manifold.

A second-order method landing on the Stiefel manifold via Newton$\unicode{x2013}$Schulz iteration

2026-05-04 · Xinhui Xiong, Bin Gao, P. -A. Absil arxiv

Retraction-free approaches offer attractive low-cost alternatives to Riemannian methods on the Stiefel manifold, but they are often first-order, which may limit the efficiency under high-accuracy requirements. To this en…

Fast and accurate optimization on the orthogonal manifold without retraction

2021-02-15 · Pierre Ablin, Gabriel Peyré

We consider the problem of minimizing a function over the manifold of orthogonal matrices. The majority of algorithms for this problem compute a direction in the tangent space, and then use a retraction to move in that d…
