MklDependentLearners maybe? it just separation of standard/additional learner is unclear from the names #Closed

There was a problem hiding this comment. was thinking that we could use it for other learners, that we don;t want on the core package because of other dependencies. We could bundle them all in one package.. In reply to: 206356744 [](ancestors = 206356744)

There was a problem hiding this comment. I suggest we continue the discussion in the other comment (Learners.nupkgproj) and close this one In reply to: 206357569 [](ancestors = 206357569,206356744) |

| <remarks> | ||
| <a href='https://en.wikipedia.org/wiki/Ordinary_least_squares'>Ordinary least squares (OLS)</a> is a parameterized regression method. | ||
| It assumes that the conditional mean of the dependent variable follows a linear function of the dependent variables. | ||
| The parameters of the regressor can be estimated by minimizing the squares of the difference between observed values and the predictions. | ||

The name "additional learners" is something we might want to reconsider, since in future as we publish more wrappers we will surely want descriptive names.
I think naming it
OrdinaryLeastSquaresis probably a fine choice since that's literally all it is? #PendingThere was a problem hiding this comment.

I was thinking that maybe we can have SymSGD here too, and other learners that need to drag dependencies?
@Ivanidzo4ka didn't like it either and suggested MklDepsLearners.

MklDeps also doesn't feel good, but it's better. Can we have a name that conveys 'these learners use MKL's optimized linear algebra', without actually saying 'MKL' in the name?
I don't think this should be 'all learners with big dependencies', because it doesn't actually improve the experience too much (if you need one of these learners, you have to grab all). I'd much rather have 'learners depending on MKL' and 'learners depending on OtherHeaveDependency' separate

renaming it to HalLearners. If that doesn's sound good, please suggest a name :)
