----------------------------------------
Summary: New transformcolmap builtin function
Key: SYSTEMML-1927
URL: https://issues.apache.org/jira/browse/SYSTEMML-1927
Project: SystemML
Issue Type: Task
Reporter: Matthias Boehm
Our decision tree script requires dummy coded inputs (in case of categorical
attributes) as well as a mapping matrix indicating which attributes where
mapped to which dummy coded features. This task aims to introduce a builtin
function {{transformcolmap}} that allows to directly compute this mapping
matrix from the frame meta data, returned from {{transformencode}}.
Once this builtin function is in place, we might want to simplify the decision
tree script, doing all this pre-processing internally instead of require the
user to handle it.
