Hakim commented on MAHOUT-840: ----------------------------------------- Hi Ikumasa > I attached new patch which has the additional modifications for DataLoader.parseString(). Cool, thanks. > For DataConverter.convert(), > my old patch has the modification, so no change is made on this. Ah, I thought your last patch included all the modifications. So should I apply all three patches one after another ? > Yes, I have an own TreeBuilder and ResultAnalyzer for regression dataset. > But I feel it is better that the patch for MAHOUT-840 doesn't have them. > Is it good? If you can add them to the patch as well that would be awesome !!! > Decision Forests should support Regression problems > --------------------------------------------------- > > Key: MAHOUT-840 > URL: https://issues.apache.org/jira/browse/MAHOUT-840 > Project: Mahout > Issue Type: New Feature > Components: Classification > Reporter: Deneche A.
