Andrew Palumbo commented on MAHOUT-1932:
----------------------------------------
+1 there are also several in-core native options that we may want to consider,
some in ViennaCL even.

> Interchangeable Solvers
> ------------------------

> Key: MAHOUT-1932
> URL: https://issues.apache.org/jira/browse/MAHOUT-1932
> Project: Mahout
> Issue Type: Improvement
> Components: Algorithms
> Affects Versions: 0.13.0
> Reporter: Trevor Grant
>
> Currently all algorithms are solving 'closed' form.
> It would be good to create open form solvers and optionally invoke them.
> Two such solvers are Stochastic Gradient Descent, and Genetic Algorithms.
> An abstract solver trait, and implementations of at least these two solving
> mechanisms (to avoid bias in choosing what to include/not include in the
> Solver trait).
> Refactoring current algorithms to accept optional Solver.
