A Guide for Sparse PCA: Model Comparison and Applications [PDF]

open access: yesPsychometrika, 2021
PCA is a popular tool for exploring and summarizing multivariate data, especially those consisting of many variables. PCA, however, is often not simple to interpret, as the components are a linear combination of the variables. To address this issue, numerous methods have been proposed to sparsify the nonzero coefficients in the components, including ...

Hyperspectral Image Denoising via Nonlocal Spectral Sparse Subspace Representation

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
Hyperspectral image (HSI) denoising based on nonlocal subspace representation has attracted a lot of attention recently. However, most of the existing works mainly focus on refining the representation coefficient images (RCIs) using certain nonlocal ...

Fast acquisition method using modified PCA with a sparse factor for burst DS spread-spectrum transmission

open access: yesICT Express, 2023
To improve the acquisition speed and inbound capacity of the ground station in a burst direct-sequence (DS) spread-spectrum transmission system, an acquisition method based on a modified parallel code-phase acquisition (PCA) scheme is proposed. By taking

Online Tensor Robust Principal Component Analysis

open access: yesIEEE Access, 2022
Online robust principal component analysis (RPCA) algorithms recursively decompose incoming data into low-rank and sparse components. However, they operate on data vectors and cannot directly be applied to higher-order data arrays (e.g. video frames). In
