------------------------------------
Summary: Multiclass to Binary Reduction
Key: SPARK-7015
URL: https://issues.apache.org/jira/browse/SPARK-7015
Project: Spark
Issue Type: Improvement
Components: MLlib
Reporter: Ram Sriharsha
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.
