This release adds the alternative scikit-learn 0.18 syntax (scikit-learn was released on Sep 28, 2016). Code that was written in scikit-learn remains compatible to future versions of scikit-learn (likely until scikit-learn 0.20).
However, to avoid deprecation warnings and to become familiar with the changes (e.g., the cross_validation and grid_search are now summarized in the new model_selection module), a scikit-learn 0.18 compatibility layer was added to the notebooks in this repository. The code is fully backwards compatible. For more information on scikit-learn 0.18, please refer to the official Release Notes.
