Stochastic Stepwise Ensembles for Variable Selection

Published 2010 in Journal of Computational and Graphical Statistics

ABSTRACT

In this article, we advocate the ensemble approach for variable selection. We point out that the stochastic mechanism used to generate the variable-selection ensemble (VSE) must be picked with care. We construct a VSE using a stochastic stepwise algorithm and compare its performance with numerous state-of-the-art algorithms. Supplemental materials for the article are available online.
