Some Two-Step Procedures for Variable Selection in High-Dimensional Linear Regression

Jian Zhang, Xinge Jessie Jeng, Han Liu

We study the problem of high-dimensional variable selection via some two-step procedures. First we show that given some good initial estimator which is $ℓ_{\infty}$ -consistent b…

On the $ℓ_{1} - ℓ_{q}$ Regularized Regression

Han Liu, Jian Zhang

In this paper we consider the problem of grouped variable selection in high-dimensional regression using $ℓ_{1} - ℓ_{q}$ regularization ( $1 \leq q \leq \infty$ ), which can be viewed…
