The sklearn.feature_extraction module can be used to extract features in a format supported by machine learning algorithms from datasets consisting of formats such as text and image. Note Feature extraction is very different from Feature selection : the former consists in transforming arbitrary data, such as text or images, into numerical features usable for machine learning.
Attributes estimator_ an estimator The base estimator from which the transformer is built. This is stored only when a non-fitted estimator is passed to the SelectFromModel, i.e when prefit is False. n_features_in_ int Number of features seen during fit.. feature_names_in_ ndarray of shape (n_features_in_,) Names of features seen during fit.Defined only when X has feature names …
The estimator should have a feature_importances_ or coef_ attribute after fitting. Otherwise, the importance_getter parameter should be used. threshold str or float, default=None. The threshold value to use for feature selection. Features whose importance is greater or equal are kept while the others are discarded.

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. In the case of unsupervised learning, this Sequential Feature Selector looks ...
