@luisquintanilla maybe we can add an opiton to re-sample dataset in advanced training option in order to deal with imbalanced data?

Currently, transformer to resample imbalanced data is missing in ml.net, but in the long run, it's definitely worthwhile to implement that.

@luisquintanilla Please take a look when you have a chance.

Thanks for looking into this @LittleLittleCloud. We can't implement anything in Model Builder until it's in the framework. Moving it to that repo for now.
