Adaptive Lasso and group-Lasso for functional Poisson regression

open access: yesJ. Mach. Learn. Res., 2014
High dimensional Poisson regression has become a standard framework for the analysis of massive counts datasets. In this work we estimate the intensity function of the Poisson regression model by using a dictionary approach, which generalizes the classical basis approach, combined with a Lasso or a group-Lasso procedure.

Bayesian Regularisation in Structured Additive Regression Models for Survival Data [PDF]

open access: yes, 2008
During recent years, penalized likelihood approaches have attracted a lot of interest both in the area of semiparametric regression and for the regularization of high-dimensional regression models.

Comparison of linear regression models Ordinary Lasso, Adaptive Group Lasso and Ordinary Least Squares models in selecting effective characteristics to predict the expected return [PDF]

open access: yesIranian Journal of Finance, 1999
In this study, for the selection of the characteristics of the company that provides the incremental information to investors and financial analysts, the linear models are adapted by the ordinary Lasso method (Tibshirani, 1996), Adaptive Group LASSO (Zu,

A fast adaptive Lasso for the cox regression via safe screening rules

open access: yes, 2021
Some interesting recent studies have shown that safe feature elimination screening algorithms are useful alternatives in solving large scale and/or ultra-high-dimensional Lasso-type problems.

Sparse Bayesian Learning Using Adaptive LASSO Priors

open access: yes, 2022
To improve the recovery accuracy of sparse signal, we study on sparse Bayesian learning (SBL) algorithm using adaptive least absolute shrinkage and selection operator (LASSO) priors.

Interval prediction of distribution network loop-closing current based on LASSO and GRU-attention mechanism

open access: yesDianzi Jishu Yingyong
Against the backdrop of large-scale integration of distributed energy resources, such as photovoltaic and wind power, into the power grid, traditional methods for calculating loop-closing currents face challenges of insufficient accuracy and difficulty ...

On Lasso and adaptive Lasso for non-random sample in credit scoring [PDF]

open access: yesStatistical Modelling, 2022
Prediction models in credit scoring are often formulated using available data on accepted applicants at the loan application stage. The use of this data to estimate probability of default (PD) may lead to bias due to non-random selection from the population of applicants.
