A contribution to condition numbers of the multidimensional total least squares problem with linear equality constraint
Qiaohua Liu, Zhigang Jia, Yimin Wei
This paper is devoted to condition numbers of the multidimensional total least squares problem with linear equality constraint (TLSE). Based on the perturbation theory of invariant…
Randomized Quaternion Singular Value Decomposition for Low-Rank Approximation
Qiaohua Liu, Sitao Ling, Zhigang Jia
This paper presents a randomized quaternion singular value decomposition (QSVD) algorithm for low-rank matrix approximation problems, which are widely used in color face recognitio…
The Multi-Symplectic Lanczos Algorithm and Its Applications to Color Image Processing
Zhigang Jia, Xuan Liu, Mei-Xiang Zhao
Low-rank approximations of original samples are playing more and more an important role in many recently proposed mathematical models from data science. A natural and initial requi…
Log orthogonal functions: approximation properties and applications
Sheng Chen, Jie Shen
We present two new classes of orthogonal functions, log orthogonal functions (LOFs) and generalized log orthogonal functions (GLOFs), which are constructed by applying a map…
