Nettet20. mar. 2024 · How recursive feature elimination (RFE) works? In recursive feature elimination, we repeatedly train a model multiple times and each time we remove the least important feature from model determined by coef_ or feature_importance_ attribute of the model. We do this process until the model performance become worse. Nettet28. feb. 2024 · To understand what that means, remember that Recursive Feature Elimination (RFE) works by training the model, evaluating it, then removing the step least significant features, and repeating. So, _grid_score[-1] will be the score of the estimator trained on all features. _grid_score[-2] will be the score of the estimator with step …
