ControlBurn: Feature Selection by Sparse Forests [article]

Brian Liu and Miaolan Xie and Madeleine Udell
2021 pre-print
In this paper we present ControlBurn, a feature selection algorithm that uses a weighted LASSO-based feature selection method to prune unnecessary features from tree ensembles, just as low-intensity fire  ...  We show that ControlBurn performs substantially better than feature selection methods with comparable computational costs on datasets with correlated features.  ...  We fit a random forest classifier on the features selected by ControlBurn and the features selected by our random forest baseline and compare the difference in test performance.  ...

ControlBurn: Nonlinear Feature Selection with Sparse Tree Ensembles [article]

Brian Liu, Miaolan Xie, Haoyue Yang, Madeleine Udell
2022 arXiv   pre-print
ControlBurn is a Python package to construct feature-sparse tree ensembles that support nonlinear feature selection and interpretable machine learning.  ...  The package includes visualizations to analyze the features selected by the ensemble and their impact on predictions.  ...  As a result, ControlBurn will select either all or none of the features; there is no feature-sparse subforest (except the empty forest).  ...
