Matthias Boehm commented on SYSTEMML-1351:
------------------------------------------
thanks [~bdwyer] - making the model layouts consistent across algorithms
(including their predict scripts) is certainly useful. Note that some
algorithms such as L2SVM further encode additional information (pos/neg labels)
in the model. I'd recommend to make this change in our 1.0 release as it would
change the "signature" of our algorithms.
> Consistent intercept return

> Key: SYSTEMML-1351
> URL: https://issues.apache.org/jira/browse/SYSTEMML-1351
> Project: SystemML
> Issue Type: Brainstorming
> Components: Algorithms
> Reporter: Brendan Dwyer
> Priority: Trivial
> Labels: easyfix
> Original Estimate: 10m
> Remaining Estimate: 10m

> Some algorithms return the intercept as the first column (for example
> [GLM.dml:448|https://github.com/apache/incubator-systemml/blob/master/scripts/algorithms/GLM.dml#L448])
> while other algorithms return it as the last column (for example
> [LinearRegDS.dml:219|https://github.com/apache/incubator-systemml/blob/master/scripts/algorithms/LinearRegDS.dml#L219])
> I think it would be nice if it was consistently returned as either the first
> or the last column.
