Hello, I've added support of distributed OLS regression per IGNITE-5846 [1] and would want to push these to master.
Changes impact "ml" module, more details of portion of code can be found in PR #3030 [2]. Yury Babak [3], Oleg Ignatenko[4] did review and sanity check. The main idea was to keep OLS Regression as algorithm and add support of many operations on SparseDistributedMatrix and SparseBlockDistributedMatrix. To implement this functionality I added SparseBlockDistributedVector and SparseDistributedVector classes. Also a few operations on distributed vectors and matrices were implemented using power of affinity. The successful build could be found here [5] [1] <goog_1261495998>https://issues.apache.org/jira/browse/IGNITE-5846 [2] <goog_1261495993>https://github.com/apache/ignite/pull/3030 [3] https://github.com/ybabak [4] https://github.com/oignatenko [5] https://ci.ignite.apache.org/viewLog.html?buildId=945536&buildTypeId=Ignite20Tests_IgniteMl&tab=buildResultsDiv Sincerely yours, Alex
