Subject Re: [DISCUSS] Roadmap SystemML 1.0
Date Tue, 17 Jan 2017 02:20:45 GMT
Now that we've had some discussion here, it would be good to transfer this discussion into
a JIRA epic, containing sub tasks. That way, we can properly track our progress on these items
and facilitate contributions from the community.  Note that some of the sub tasks may already
exist as individual issues.

Would anyone in the community like to volunteer for creating these issues?

it contains several user-facing items.  However, to echo what Luciano said, I'm also concerned
about the timeline.  At this stage, I agree that we need to release more often, and with a
more user-oriented "product" focus as a guide for timelines.  I.e. we should orient our release
timelines around items that focus on the "product" of allowing the user to work on a wide
range of ML problems in a simple and easy manner on top of Spark.
