Re: Add support of distributed matrices for OLS regression. (PR #3030 / IGNITE-5846)

[Alexey Zinoviev]

The documentation is corect, all changes are added for internals in
reality, without changes in API.

Hi Alex,

Impressive, thanks for sharing this with us. Btw, do we need to tweak the 
existing OLS documentation to mention the contributed changes?

Add support of distributed matrices for OLS regression. (PR #3030 / IGNITE-5846)

[Alexey Zinoviev]

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]
