Feat is a feature engineering automation tool that learns new representations of raw data to improve classifier and regressor performance. The underlying methods use Pareto optimization and evolutionary computation to search the space of possible transformations.

Feat wraps around a user-chosen ML method and provides a set of representations that give the best performance for that method. Each individual in Feat's population is its own data representation.

Feat uses the Shogun C++ ML toolbox to fit models.
