Deneche A. Hakim commented on MAHOUT-840:
-----------------------------------------
the examples went all fine, I just committed the patch after making the
following changes:
- removed TreePrinter, ForestPrinter, ArffDataLoader, ArffData,
ArffInvalidFormatException. These are really helpful additions but they aren't
needed to support Regression. So they should probably be submitted in a new
jira post (go ahead and create one)
- I made some style modifications using IntelliJ code inspection
I do have one question: I see that DecisionTreeBuilder supports both
classification and regression tree. Should we remove DefaultTreeBuilder and
just use DecisionTreeBuilder instead ?
> Decision Forests should support Regression problems
