I will soon update first version of patch.
> Solving linear solution with Conjugate Gradient Method
> ------------------------------------------------------
>
> Key: HAMA-233
> URL: https://issues.apache.org/jira/browse/HAMA-233
> Project: Hama
> Issue Type: New Feature
> Components: matrix
> Affects Versions: 0.1.0
> Reporter: Sangwon Seo
> Assignee: Sangwon Seo
> Priority: Minor
> Fix For: 0.1.0
>
>
> For spase matrix, CG method is good in a way of iterative learning.
> This can be applied to many applications (MLP, descent gradient search,
> etc..) as a primitive, not even in linear solution.
> Related paper (From Carnegie Mellon, It presents in verry simple way to
> understand everything behind the CG) is as bellow.
