Error Analysis for Matrix Elastic-Net Regularization Algorithms

IEEE Transactions on Neural Networks and Learning Systems, 2012
Elastic-net regularization is a successful approach in statistical modeling. It can avoid large variations which occur in estimating complex models. In this paper, elastic-net regularization is extended to a more general setting, the matrix recovery (matrix completion) setting.

Regularization and Variable Selection Via the Elastic Net [PDF]

Journal of the Royal Statistical Society Series B: Statistical Methodology, 2005
SummaryWe propose the elastic net, a new regularization and variable selection method. Real world data and a simulation study show that the elastic net often outperforms the lasso, while enjoying a similar sparsity of representation. In addition, the elastic net encourages a grouping effect, where strongly correlated predictors tend to be in or out of ...

Type-1 fuzzy forecasting functions with elastic net regularization

Expert Systems With Applications, 2022
Fuzzy functions have recently been used for forecasting problems. The main concepts behind a fuzzy functions are to cluster the inputs using a fuzzy clustering method and to include the obtained membership grades and their non-linear transformations as new variables in the input matrix.

Learning performance of elastic-net regularization

Mathematical and Computer Modelling, 2013
In this paper, within the framework of statistical learning theory we address the elastic-net regularization problem. Based on the capacity assumption of hypothesis space composed by infinite features, significant contributions are made in several aspects.

ELASTIC-NET REGULARIZATION FOR LOW-RANK MATRIX RECOVERY

International Journal of Wavelets, Multiresolution and Information Processing, 2012
This paper considers the problem of recovering a low-rank matrix from a small number of measurements consisting of linear combinations of the matrix entries. We extend the elastic-net regularization in compressive sensing to a more general setting, the matrix recovery setting, and consider the elastic-net regularization scheme for matrix recovery.

Elastic Net Regularization in Diffuse Optical Tomography Applications

2019 IEEE 16th International Symposium on Biomedical Imaging (ISBI 2019), 2019
Diffuse optical tomography (DOT) uses near-infrared light to obtain quantitative information about the optical coefficients in biological tissues. Such an information can be clinically exploited for diagnostic purposes. In DOT, the surface of the investigated tissue is illuminated with a light source and the emerging light is measured at various ...

Elastic-Net Regularization: Iterative Algorithms and Asymptotic Behavior of Solutions

Numerical Functional Analysis and Optimization, 2010
We derive strongly convergent algorithms to solve inverse problems involving elastic-net regularization. Moreover, using functional analysis techniques, we provide a rigorous study of the asymptotic properties of the regularized solutions that allows to cast in a unified framework l1, elastic-net and classical Tikhonov regularization.

Elastic Net Regularization in Lorentz force evaluation

NDT & E International, 2018
Abstract Lorentz force evaluation is a nondestructive evaluation method applied for the characterization of sub-surface defects in specimen consisting of layers of conducting material. The movement of a specimen under investigation relative to a permanent magnet leads to Lorentz forces that are perturbed in the presence of a defect.
