Description

I suggest to add target encoding processor based on "Daniele Miccii-Barreca (2001). A Preprocessing Scheme for High-Cardinality Categorical Attributes in Classification and Prediction Problems. SIGKDD Explor. Newsl. 3, 1. From http://dx.doi.org/10.1145/507533.507538" and implemented in "scikit-learn-contrib/category_encoders" as TargetEncoder (https://github.com/scikit-learn-contrib/category_encoders/blob/master/category_encoders/target_encoder.py).
