Multi-View Learning With Robust Generalized Eigenvalue Proximal SVM

open access: yesIEEE Access, 2019
Multi-view learning mechanism, which enhances learning performance by training multi-model data sets, is a popular filed in recent years. Multi-view generalized eigenvalue proximal support vector machine (MvGSVM), as a most recently proposed classifier ...

An Adaptive Lp Norm Minimization Algorithm for Direction of Arrival Estimation

open access: yesRemote Sensing, 2022
In this paper, we propose a new direction of arrival (DOA) estimation algorithm, in which DOA estimation is achieved by finding the sparsest support set of multiple measurement vectors (MMV) in an over-complete dictionary. The proposed algorithm is based

An Improved Proportionate Normalized Least-Mean-Square Algorithm for Broadband Multipath Channel Estimation

open access: yesThe Scientific World Journal, 2014
To make use of the sparsity property of broadband multipath wireless communication channels, we mathematically propose an lp-norm-constrained proportionate normalized least-mean-square (LP-PNLMS) sparse channel estimation algorithm.

A new robust dynamic state estimation approach for power systems with non-Gaussian noise

open access: yesInternational Journal of Electrical Power & Energy Systems
The Gaussian noise distribution is typically used in dynamic state estimation (DSE) but it is not always true in practice because of abnormal system inputs, impulsive noise and measurement outliers. In this paper, a new robust DSE approach based on a new

Sparse FIR Filter Design Based on Signomial Programming

open access: yesElektronika ir Elektrotechnika, 2020
The goal of sparse FIR filter design is to minimize the number of nonzero filter coefficients, while keeping its frequency response within specified boundaries.

On approximation in the Lp-norm by Hermit interpolation

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1992
Lp-approximation by the Hermite interpolation based on the zeros of the Tchebycheff polynomials of the first kind is considered. The corresponding result of Varma and Prasad [1] is generalized and perfected.

Maximum norm a posteriori error estimate for a 2d singularly perturbed semilinear reaction-diffusion problem

open access: yes, 2008
A singularly perturbed semilinear reaction-diffusion equation, posed in the unit square, is discretized on arbitrary nonuniform tensor-product meshes. We establish a second-order maximum norm a posteriori error estimate that holds true uniformly in the ...

Superconvergence of a finite element method for linear integro-differential problems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
We introduce a new way of approximating initial condition to the semidiscrete finite element method for integro-differential equations using any degree of elements. We obtain several superconvergence results for the error between the approximate solution
