Hi Andrey, Yes, this would be great. Actually, it was on my todo list for some time now. And now that you have requested it, it should become top priority for me. I'm just waiting for the release of Mahout-0.4 and the end of the code freeze and I will add both the "maxDepth" to DefaultTreeBuilder and start working on this one. I also found what was causing the infinite recursion on your dataset, a patch is available here: https://issues.apache.org/jira/browse/MAHOUT-526 I should commit it as soon as the code freeze ends.
Thanks for your feedback, Deneche On Tue, Oct 26, 2010 at 10:00 PM, Andrey Gusev <[email protected]> wrote: > Hey Deneche, > I wanted to also let you know about another feature that may be useful for > bagged decision trees.
