Hi-LASSO in Python

This library provides Hi-LASSO(High-Dimensional LASSO).

What is Hi-LASSO?

Hi-LASSO(High-Dimensional LASSO) can theoretically improves a LASSO model providing better performance of both prediction and feature selection on extremely high-dimensional data. Hi-LASSO alleviates bias introduced from bootstrapping, refines importance scores, improves the performance taking advantage of global oracle property, provides a statistical strategy to determine the number of bootstrapping, and allows tests of significance for feature selection with appropriate distribution. In Hi-LASSO will be applied to use the pool of the python library to process parallel multiprocessing to reduce the time required for the model.


Hi-LASSO was primarily developed by Dr. Youngsoon Kim, with significant contributions and suggestions by Dr. Joongyang Park, Dr. Mingon Kang, and many others. The python package was developed by Jongkwon Jo. Initial supervision for the project was provided by Dr. Mingon Kang.

Development of Hi-LASSO is carried out in the DataX lab at University of Nevada, Las Vegas (UNLV).
