Ikumasa Mukai updated MAHOUT-840:
---------------------------------
Attachment: regression.patch
Hello,
This is my first comment on jira.
Now I am trying to implement a TreeBuilder which can also be used for
Regression problems with MAHOUT-840 modifications.
For this, I think some additional modifications are needed (patch attached).
Could you please check this patch?
This patch contains these points.
1) Changed target and prediction params from int to double.
2) Added the prediction for regression problem (using majority rule if target
param is numeric)
3) Added changes for using numeric target param.
4) Added changes for detecting the target param type.
5) Added a func on Dataset for getting the number of category type params.
cheers
