Shirokumas

A set of scikit-learn style transformers for Polars. The transformers have the following property:

• Support for polars DataFrame as an input and output
• Can explicitly configure which columns will be encoded

How to install

$ pip install git+https://github.com/momijiame/shirokumas.git

How to use

import shirokumas as sk

encoder = sk.AggregateEncoder(...)
encoder = sk.CountEncoder(...)
encoder = sk.NullEncoder(...)
encoder = sk.OneHotEncoder(...)
encoder = sk.OrdinalEncoder(...)
encoder = sk.TargetEncoder(...)

train_x, train_y, test_x = ...

encoder.fit(train_x, train_y)
encoded_train_x = encoder.transform(train_x, train_y)
encoded_test_x = encoder.transform(test_x)
