FEW

Feature Engineering Wrapper

Few is a feature engineering wrapper that pairs with any ML estimator to generate a readable representation that facilitates learning. It is implemented to pair easily with any scikit-learn-base estimator.

Few uses genetic programming to generate, search and update engineered features. It incorporates feedback from the ML process to select important features, while also scoring them internally.
