Hello all,
It seems Robin Anil hasn't responded, and no one is sure of the status on this.
What needs to be done on this, and/or what can I do to help? I'm no ML expert,
but I do have the paper and should be able to verify/fix the implementation.
I'm REALLY interested in using the CNB
Which Mahout version r u running? While its true that ThetaNormalizer is still
disabled today, Mahout-1389 fixes a bug wherein Complementary NB wasn't being
called when invoked.
Please test with Mahout 0.9 or trunk.

Hi Chandler,
I think a good way to go would be to reenable theta normalization and
run the classification examples that we already have to see how it
affects the result (and make sure it improves the result).
Would be great to have this fixed. I'm also planning to port NB to our

Hi Suneel,
I'm using 0.9. I did not train using Complementary NB, but was only using it
for testing. I'm not real familiar with the math but can see CNBClassifier is
scoring differently than SNBClassifier, so I thought I would see something, but
the scores and results from testnb didn't
Ok, I'll uncomment those lines and see. I also have plenty of test data
available too (I'm doing document classification with unbalanced classes), so
I'll see if it improves there as well.
Also, I'll try to make some time in the next week and go over the algorithm in
detail compared with the

Initial github repo:
Just checking , u r testing Cbayes on a model that's already been trained using
Cbayes correct?
Also the jira I mentioned earlier was fixed for .9, so u should be good. No
code changes were done to naive bayes since .9

The program I wrote didn't use a model that was trained with Cbayes. After
looking at the scorers in SNB and CNB, I figured they would give different
results even on a model not trained with CNB. That could very well be ignorance
on my part as to the math.
However, I did some command line
so the only distributed use here is the colsums summaries, right?
