A Consistent and Scalable Algorithm for Best Subset Selection in Single Index Models

no code implementations12 Sep 2023 Borui Tang, Jin Zhu, Junxian Zhu, Xueqin Wang, Heping Zhang

SIMs provide an interpretable and flexible modeling framework for high-dimensional data, while best subset selection aims to find a sparse model from a large set of predictors.

Optimal and Safe Estimation for High-Dimensional Semi-Supervised Learning

no code implementations28 Nov 2020 Siyi Deng, Yang Ning, Jiwei Zhao, Heping Zhang

Our goal is to investigate when and how the unlabeled data can be exploited to improve the estimation of the regression parameters of linear model in light of the fact that such linear models may be misspecified in data analysis.
