The binomial sequence spaces which include the spaces ℓ p $\ell_{p}$ and ℓ ∞ $\ell_{\infty}$ and geometric properties

open access: yesJournal of Inequalities and Applications, 2016
In this work, we introduce the binomial sequence spaces b p r , s $b^{r,s}_{p}$ and b ∞ r , s $b^{r,s}_{\infty}$ which include the spaces ℓ p $\ell_{p}$ and ℓ ∞ $\ell _{\infty}$ , in turn. Moreover, we show that the spaces b p r , s $b^{r,s}_{p}$ and b ∞

Ridge estimation of covariance matrix from data in two classes [PDF]

open access: yes, 2000
summary:This paper deals with the problem of estimating a covariance matrix from the data in two classes: (1) good data with the covariance matrix of interest and (2) contamination coming from a Gaussian distribution with a different covariance matrix ...

Compactness of quadruple band matrix operator and geometric properties

open access: yesAnnales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2022
In this work, we characterize the class of compact matrix operators from c0(Q), c(Q) and l∞(Q) into c0, c and l∞, respectively, with the notion of the Hausdorff measure of noncompactness.

The Q-Matrix Anchored Mixture Rasch Model

open access: yesFrontiers in Psychology, 2021
Mixture item response theory (IRT) models include a mixture of latent subpopulations such that there are qualitative differences between subgroups but within each subpopulation the measure model based on a continuous latent variable holds.

Hierarchical CNN Classification of Hyperspectral Images Based on 3-D Attention Soft Augmentation

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
The distinction of similar classes has always been the core issue in image classification. In this article, a new hierarchical classification process based on three-dimensional attention soft augmentation (HC-3DAA) is proposed to improve the accuracy of ...

The Hadamard Product of a Nonsingular General H-Matrix and Its Inverse Transpose Is Diagonally Dominant

open access: yesJournal of Applied Mathematics, 2015
We study the combined matrix of a nonsingular H-matrix. These matrices can belong to two different H-matrices classes: the most common, invertible class, and one particular class named mixed class.
