Hyperspectral Target Detection With Target Prior Augmentation and Background Suppression-Based Multidetector Fusion

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Hyperspectral target detection (HTD) methods aim to exploit the abundant hyperspectral information to distinguish the key target pixels from multifarious background pixels.

Relative-Error $CUR$ Matrix Decompositions [PDF]

SIAM Journal on Matrix Analysis and Applications, 2008
Many data analysis applications deal with large matrices and involve approximating the matrix using a small number of ``components.'' Typically, these components are linear combinations of the rows and columns of the matrix, and are thus difficult to interpret in terms of the original features of the input data.

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

Advanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

An Improved Coordinated Multi-point Multi-user Precoding Algorithm

Journal of Harbin University of Science and Technology, 2018
In Long Term Evolution-Advanced ( LTE-A) system，existing coordinated multi-point ( CoMP) multiuser precoding algorithm can not suppress multi-user，intra-user and noise interference at the same time and its computational complexity is high.

Sparse and Low-Rank Matrix Decompositions [PDF]

IFAC Proceedings Volumes, 2009
Abstract Suppose we are given a matrix that is formed by adding an unknown sparse matrix to an unknown low-rank matrix. Our goal is to decompose the given matrix into its sparse and low-rank components. Such a problem arises in a number of applications in model and system identification, but obtaining an exact solution is NP-hard in general.

Investigating the Low‐Temperature Phase Stability of the Binary Ta–W System

Advanced Engineering Materials, EarlyView.
Atomistic simulations show that the binary Ta–W system forms ordered intermetallic phases, B2‐TaW and D03‐TaW3, as 0 K ground states. Configurational entropy, however, lowers the free energy of the disordered bcc solid solution, which becomes the stable phase above about 400 K.

On the use of certain matrix algebras associated with trigonometric transforms in matrix displacement decomposition

, 1995
The authors extend some recent results of Di Fiore and Zellini [Linear Algebra Appl., to appear], obtaining new classes of formulas for the displacement operator-based decomposition of matrices. It is shown how an arbitrary matrix can be expressed as the

Matrix algebras with Multiplicative Decomposition Property [PDF]

, 2011
We consider the Multiplicative Decomposition Property (the multiplicative analogue of the Riesz Decomposition Property) for entry-wise ordered matrix algebras over the reals. We characterize for which matrix pairs such a decomposition exists and use this
