=============================
Given an external estimator that assigns weights to features (e.g., the
-coefficients of a linear model), recursive feature elimination (:class:`RFE`)
+coefficients of a linear model), the goal of recursive feature elimination (:class:`RFE`)
is to select features by recursively considering smaller and smaller sets of
features. First, the estimator is trained on the initial set of features and
the importance of each feature is obtained either through any specific attribute
