Ikumasa Mukai commented on MAHOUT-840:
--------------------------------------
Thank you so much for adopting my patch!
I am glad I can contribute to your project.
> DecisionTreeBuilder supports both classification and regression tree.
> Should we remove DefaultTreeBuilder and just use DecisionTreeBuilder instead ?
Yes, I think so.
Because we can get same result if we use DecisionTreeBuilder with disabling
pruning and complementing functions.
(I made DecisionTreeBuilder refering to DefaultTreeBuilder.)
So I will make an additional patch for enabling to change the
params(minSplitNum, complemented etc..) for DecisionTreeBuilder from
outside(command line), and will attach to this jira.
Regards,
