WebNov 23, 2024 · Several methodologies of feature selection are available in Sci-Kit in the sklearn.feature_selection module. They include Recursive Feature Elimination (RFE) and Univariate Feature Selection. Feature selection using SelectFromModel allows the analyst to make use of L1-based feature selection (e.g. Lasso) and tree-based feature selection.
