Consistency of the total least squares estimator in the linear errors-in-variables regression

Modern Stochastics: Theory and Applications, 2018
This paper deals with a homoskedastic errors-in-variables linear regression model and properties of the total least squares (TLS) estimator. We partly revise the consistency results for the TLS estimator previously obtained by the author [18]. We present

Some bounds for the spectral norms of some circulant matrices with generalized Jacobsthal–Lucas numbers

Mathematics Open
The purpose of this paper is to investigate the bounds of the spectral norms of some circulant matrices whose elements are a generalization of Jacobsthal–Lucas numbers called bi-periodic Jacobsthal–Lucas numbers by three different ways.

Classification of Hyperspectral Images Using Kernel Fully Constrained Least Squares

ISPRS International Journal of Geo-Information, 2017
As a widely used classifier, sparse representation classification (SRC) has shown its good performance for hyperspectral image classification. Recent works have highlighted that it is the collaborative representation mechanism under SRC that makes SRC a ...

The spectral norm of a nonnegative matrix

Linear Algebra and its Applications, 1990
The author proves that for any matrix \(A=(a_{ij})\) with \(| A| =(| a_{ij}|)\) it holds that \(\| | A| \|_ 2=\min \{r_ 1(B)\cdot c_ 1(C):\) \(B\circ C=A\}\geq \| A\|_ 2\) and determines the case of equality and the conditions of the uniqueness of minimizers, where \(c_ 1(A)=\max_{j}(\sum_{i}| a_{ij}|^ 2)^{1/2}\) and \(r_ 1(A)=\max_{i}(\sum_{j}| a_{ij}|

Sparsity-Enhanced Constrained Least-Squares Spectral Analysis with Greedy-FISTA

Remote Sensing
The utilization of the inversion-based algorithm for spectral decomposition using constrained least-squares spectral analysis (CLSSA) facilitates a time–frequency spectrum with higher temporal and frequency resolution. The conventional CLSSA algorithm is

Global Existence and Convergence Rates for the Strong Solutions in H2 to the 3D Chemotaxis Model

Journal of Applied Mathematics, 2013
We are concerned with a 3D chemotaxis model arising from biology, which is a coupled hyperbolic-parabolic system. We prove the global existence of a strong solution when H2-norm of the initial perturbation around a constant state is sufficiently small ...

Spectral expression for the Frequency-Limited H2 -norm of LTI Dynamical Systems with High Order Poles

, 2014
International audienceIn this paper, the spectral expression of the frequency-limited H2-norm, firstly presented in [18], is ex-tended to the case of LTI dynamical systems which are not diagonalizable.
