New features

  • Turn off steps in :class:pipeline.Pipeline using the None
    object. By Christos Aridas_.

  • Add a fetching function :func:datasets.fetch_datasets in order to get some
    imbalanced datasets useful for benchmarking. :issue:249 by Guillaume Lemaitre_.

Enhancement

  • All samplers accepts sparse matrices with defaulting on CSR type. :issue:316 by
    Guillaume Lemaitre_.

  • :func:datasets.make_imbalance take a ratio similarly to other samplers. It
    supports multiclass. :issue:312 by Guillaume Lemaitre_.

  • All the unit tests have been factorized and a :func:utils.check_estimators

  • __init__ has been removed from the :class:base.SamplerMixin to
    create a real mixin class. :issue:242 by Guillaume Lemaitre_.

  • creation of a module :mod:exceptions to handle consistant raising of
