von Neumann type trace inequality for dual quaternion matrices
Chen Ling, Hongjin He, Liqun Qi +1
Dual quaternion matrices have important applications in multi-agent formation control. In this paper, we first address the concept of spectral norm of dual quaternion matrices. The…
Inexact Krylov Subspace Algorithms for Large Matrix Exponential Eigenproblem from Dimensionality Reduction
Gang Wu, Ting-ting Feng, Li-jia Zhang +1
Matrix exponential discriminant analysis (EDA) is a generalized discriminant analysis method based on matrix exponential. It can essentially overcome the intrinsic difficulty of sm…
Inexact Shift-and-Invert Arnoldi for Toeplitz Matrix Exponential
Ting-ting Feng, Gang Wu, Yimin Wei
We revisit the shift-and-invert Arnoldi method proposed in [S. Lee, H. Pang, and H. Sun. {\it Shift-invert Arnoldi approximation to the Toeplitz matrix exponential}, SIAM J. Sci. C…
A theoretical contribution to the fast implementation of null linear discriminant analysis method using random matrix multiplication with scatter matrices
Ting-ting Feng, Gang Wu
The null linear discriminant analysis method is a competitive approach for dimensionality reduction. The implementation of this method, however, is computationally expensive. Recen…
