Nonconvex Low Tubal Rank Tensor Minimization

open access: yesIEEE Access, 2019
In the sparse vector recovery problem, the L0-norm can be approximated by a convex function or a nonconvex function to achieve sparse solutions. In the low-rank matrix recovery problem, the nonconvex matrix rank can be replaced by a convex function or a ...

Perceptual Low-Rank Learning and Geometry-Preserving Feature Selection for Categorizing High-Resolution Aerial Photos

open access: yesIEEE Access, 2023
Recognizing the multiple categories of an high-resolution (HR) aerial photos is an indispensable technique in geoscience and remote sensing. In this work, a perceptual low-rank algorithm combined with a geometry-preserving feature selection (FS) is ...

Low rank multivariate regression [PDF]

open access: yesElectronic Journal of Statistics, 2011
We consider in this paper the multivariate regression problem, when the target regression matrix $A$ is close to a low rank matrix. Our primary interest in on the practical case where the variance of the noise is unknown. Our main contribution is to propose in this setting a criterion to select among a family of low rank estimators and prove a non ...

Inference for low-rank models

open access: yesThe Annals of Statistics, 2023
This paper studies inference in linear models with a high-dimensional parameter matrix that can be well-approximated by a ``spiked low-rank matrix.'' A spiked low-rank matrix has rank that grows slowly compared to its dimensions and nonzero singular values that diverge to infinity.

Compressing Transformers: Features Are Low-Rank, but Weights Are Not!

open access: yesAAAI Conference on Artificial Intelligence, 2023
Transformer and its variants achieve excellent results in various computer vision and natural language processing tasks, but high computational costs and reliance on large training datasets restrict their deployment in resource-constrained settings.

Low-Rank Tensor Thresholding Ridge Regression

open access: yesIEEE Access, 2019
In the area of subspace clustering, methods combining self-representation and spectral clustering are predominant in recent years. For dealing with tensor data, most existing methods vectorize them into vectors and lose most of the spatial information ...

Low-Rank Matrix Factorization Method for Multiscale Simulations: A Review

open access: yesIEEE Open Journal of Antennas and Propagation, 2021
In this paper, a review of the low-rank factorization method is presented, with emphasis on their application to multiscale problems. Low-rank matrix factorization methods exploit the rankdeficient nature of coupling impedance matrix blocks between two ...
