Version 0.4

October, 2018

.. warning::

Version 0.4 is the last version of imbalanced-learn to support Python 2.7
and Python 3.4. Imbalanced-learn 0.5 will require Python 3.5 or higher.

Highlights

This release brings its set of new feature as well as some API changes to
strengthen the foundation of imbalanced-learn.

As new feature, 2 new modules imblearn.keras and
imblearn.tensorflow have been added in which imbalanced-learn samplers
can be used to generate balanced mini-batches.

The module imblearn.ensemble has been consolidated with new classifier:
imblearn.ensemble.BalancedRandomForestClassifier,
imblearn.ensemble.EasyEnsembleClassifier,
imblearn.ensemble.RUSBoostClassifier.

Support for string has been added in
imblearn.over_sampling.RandomOverSampler and
imblearn.under_sampling.RandomUnderSampler. In addition, a new class
imblearn.over_sampling.SMOTENC allows to generate sample with data
sets containing both continuous and categorical features.

The imblearn.over_sampling.SMOTE has been simplified and break down
to 2 additional classes:
imblearn.over_sampling.SVMSMOTE and
imblearn.over_sampling.BorderlineSMOTE.

There is also some changes regarding the API:
the parameter sampling_strategy has been introduced to replace the
ratio parameter. In addition, the return_indices argument has been
deprecated and all samplers will exposed a sample_indices_ whenever this is
possible.
