----------------------------------------
Summary: Transformencode failing for mix of recode/dummycode
features
Key: SYSTEMML-1902
URL: https://issues.apache.org/jira/browse/SYSTEMML-1902
Project: SystemML
Issue Type: Bug
Reporter: Matthias Boehm
The frame transformapply is failing if the transform specification requests a
mix of recoded and dummy coded features. For example, consider the following
transform spec on the homes dataset:
{code}
{ "recode": [ "district", "zipcode", "view" ],
"dummycode": [ "zipcode" ] }
{code}
generates the following exception:
{code}
