[jira] [Commented] (SYSTEMML-1351) Consistent intercept return

["Matthias Boehm (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SYSTEMML-1351?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15883941#comment-15883941 ] 

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.

> 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.
