WebHow is this different from Recursive Feature Elimination (RFE) -- e.g., as implemented in sklearn.feature_selection.RFE? RFE is computationally less complex using the feature weight coefficients (e.g., linear models) or feature importance (tree-based algorithms) to eliminate features recursively, whereas SFSs eliminate (or add) features based ...
