> With the new Pipeline API, it is possible to seamlessly support machine learning reductions as meta algorithms.
> GBDT and SVM today are binary classifiers and we can implement multi class classification as a One vs All, or All vs All (or even more sophisticated reduction) using binary classifiers as primitives.
> This JIRA is to track the creation of a reduction API for multi class classification.
