Ikumasa Mukai updated MAHOUT-840:
---------------------------------
Attachment: regression.patch
Hi Hakim-san.
Thank you for reviewing!
> DataLoader.parseString() and DataConverter.convert() don't take into account
> that the dataset is in "regression" mode.
I attached new patch which has the additional modifications for
DataLoader.parseString().
For DataConverter.convert(),
my old patch has the modification, so no change is made on this.
> Did you try to run BuildForest and TestForest on a regression dataset ?
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?
Regards,
> Decision Forests should support Regression problems
