Global linear and local superlinear convergence of IRLS for non-smooth robust regression

L Peng, C Kümmerle, R Vidal - Advances in neural …, 2022 - proceedings.neurips.cc
We advance both the theory and practice of robust $\ell_p $-quasinorm regression for $ p\in
(0, 1] $ by using novel variants of iteratively reweighted least-squares (IRLS) to solve the …

Block coordinate descent on smooth manifolds: Convergence theory and twenty-one examples

L Peng, R Vidal - arXiv preprint arXiv:2305.14744, 2023 - arxiv.org
Block coordinate descent is an optimization paradigm that iteratively updates one block of
variables at a time, making it quite amenable to big data applications due to its scalability …

Outlier-Robust Orthogonal Regression on Manifolds

T Ding, L Peng, R Vidal - openreview.net
Motivated by machine learning and computer vision applications, we formulate the problem
of Outlier-Robust Orthogonal Regression to find a point in a manifold that satisfies as many …
