Journal ArticleDOI
Robust quaternion matrix completion with applications to image inpainting
TL;DR: The results of missing/noisy color image pixels as a robust quaternion matrix completion problem are given to show that the performance of the proposed approach is better than that of the testing methods, including image inpainting methods, the tensor‐based completion method, and the quaternions completion method using semidefinite programming.
Journal ArticleDOI
Learning Transferred Weights From Co-Occurrence Data for Heterogeneous Transfer Learning
TL;DR: The experimental results on synthetic and real-world data sets are reported to illustrate the effectiveness of the proposed method that can capture strong or weak relations among feature spaces, and enhance the learning performance of heterogeneous transfer learning.
Proceedings ArticleDOI
Semi-supervised low-rank mapping learning for multi-label classification
TL;DR: An efficient algorithm is designed to solve SLRM model based on alternating direction method of multipliers and thus it can efficiently deal with large-scale datasets and obtain promising and better label prediction results than state-of-the-art methods.
Journal ArticleDOI
Preconditioned Iterative Methods for Weighted Toeplitz Least Squares Problems
Michele Benzi,Michael K. Ng +1 more
TL;DR: This work considers the iterative solution of weighted Toeplitz least squares problems using a variant of constraint preconditioning, and the Hermitian/skew-Hermitian splitting (HSS) preconditionser, based on an augmented system formulation.
Journal ArticleDOI
Molecular subtyping of cancer: Current status and moving toward clinical applications
TL;DR: Five frequently applied techniques for generating molecular data, which are micro array, RNA sequencing, quantitative polymerase chain reaction, NanoString and tissue microarray, are introduced and standardized methods should be established to help identify intrinsic subgroup signatures and build robust classifiers that pave the way toward stratified treatment of cancer patients.
