Project: Ignite
Issue Type: Improvement
Components: ml
Reporter: Mark Andreev

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).]
