A Hybrid Two-layer Feature Selection Method Using GeneticAlgorithm and Elastic Net

30 Jan 2020 Fatemeh Amini Guiping Hu

Feature selection, as a critical pre-processing step for machine learning, aims at determining representative predictors from a high-dimensional feature space dataset to improve the prediction accuracy. However, the increase in feature space dimensionality, comparing to the number of observations, poses a severe challenge to many existing feature selection methods with respect to computational efficiency and prediction performance...
