In OHPL: Ordered Homogeneity Pursuit Lasso for Group Variable Selection

Ordered Homogeneity Pursuit Lasso (OHPL)

Introduction

OHPL implements the ordered homogeneity pursuit lasso (OHPL) algorithm for group variable selection proposed in Lin et al. (2017) <DOI:10.1016/j.chemolab.2017.07.004> (PDF). The OHPL method exploits the homogeneity structure in high-dimensional data and enjoys the grouping effect to select groups of important variables automatically. This feature makes it particularly useful for high-dimensional datasets with strongly correlated variables, such as spectroscopic data.
