Description
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.
