WebAug 17, 2005 · Abstract. Feature selection is the task of finding a subset of original features which is as small as possible yet still sufficiently describes the target concepts. Feature selection has been approached through both heuristic and meta-heuristic approaches.

This Sequential Feature Selector adds (forward selection) or removes (backward selection) features to form a feature subset in a greedy fashion. At each stage, this estimator chooses the best feature to add or remove based on the cross-validation score of an estimator.

WebApr 27, 2024 · The feature selection method called F_regression in scikit-learn will sequentially include features that improve the model the most, until there are K features in the model (K is an input). It starts by regression the labels on each feature individually, and then observing which feature improved the model the most using the F-statistic.
