feature_selection(
    estimator: BaseEstimator,
    X: ndarray,
    y: ndarray,
    n_features_to_select: int = 3,
    feature_names: list[str] | None = None,
    **kwargs
) -> SequentialFeatureSelector

Perform feature selection to find the most important features.

Uses forward sequential feature selection to identify the most important features for the given estimator and data.

Parameters:

Name	Type	Description	Default
estimator	BaseEstimator	The model to use for feature selection	required
X	ndarray	Input features, shape (n_samples, n_features)	required
y	ndarray	Target values, shape (n_samples,)	required
n_features_to_select	int	Number of features to select	3
feature_names	list[str] | None	Names of the features (optional)	None
**kwargs		Additional parameters to pass to SequentialFeatureSelector	{}

Returns:

Name	Type	Description
SequentialFeatureSelector	SequentialFeatureSelector	Fitted feature selector that can be used to transform data to use only the selected features
