Robust Variable Selection and Regularization in Quantile Regression Based on Adaptive-LASSO and Adaptive E-NET

open access: yesComputation, 2022
Although the variable selection and regularization procedures have been extensively considered in the literature for the quantile regression (QR) scenario via penalization, many such procedures fail to deal with data aberrations in the design space ...

Simultaneous Feature Selection and Classification for Data-Adaptive Kernel-Penalized SVM

open access: yesMathematics, 2020
Simultaneous feature selection and classification have been explored in the literature to extend the support vector machine (SVM) techniques by adding penalty terms to the loss function directly.

An Analysis of Finite Element Approximation in Electrical Impedance Tomography [PDF]

open access: yes, 2013
We present a finite element analysis of electrical impedance tomography for reconstructing the conductivity distribution from electrode voltage measurements by means of Tikhonov regularization. Two popular choices of the penalty term, i.e., $H^1(\Omega)$-

Detecting Changes in Slope With an L0 Penalty [PDF]

open access: yesJournal of Computational And Graphical Statistics, 2017
While there are many approaches to detecting changes in mean for a univariate time series, the problem of detecting multiple changes in slope has comparatively been ignored.

A Theoretical Model of Sequential Combinatorial Games of Subsidies and Penalties: From Waste to Renewable Energy

open access: yesFrontiers in Energy Research, 2021
Subsidies and penalties are two main regulation methods adopted by authorities to promote the development of renewable energy. Due to the possibility of subsidy fraud, it is necessary to explore effective ways to combine these two policies.

The use of pseudo-inertia in asymptotic modelling of constraints in boundary value problems [PDF]

open access: yes, 2009
In recent publications, the validity of using positive and negative inertial penalty parameters and the advantage of this approach over the conventional positive penalty function approach have been established for linear eigenvalue problems.

Adverse childhood experience and non-suicidal self-injury in male prisoners: a chain mediating effect through sense of security and emotional problems

open access: yesFrontiers in Psychology
IntroductionNon-suicidal self-injury (NSSI) is highly prevalent among prisoners and poses substantial challenges to prison management. This study examined the mechanisms linking adverse childhood experiences (ACEs) to NSSI among male prisoners, with a ...

A unifying theory of exactness of linear penalty functions II: parametric penalty functions

open access: yes, 2017
In this article we develop a general theory of exact parametric penalty functions for constrained optimization problems. The main advantage of the method of parametric penalty functions is the fact that a parametric penalty function can be both smooth ...
