Deneche A. Hakim commented on MAHOUT-840:
-----------------------------------------
DecisionForests use the Dataset class to get informations about the attributes:
whether they are numerical or categorical, and to get all possible values of
categorical attributes. The target attribute is treated apart and supposed
always to be categorical. The first step should be to modify Dataset in order
to treat the target attribute as any other attribute, of course the remaining
code still asumes it is categorical
> Decision Forests should support Regression problems
