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.

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 classifier, since it seems well suited to the problem I'm trying to tackle, before I give up and use something else. I've done tests and see no difference when -c is passed on the command line for training or testing. I also wrote a program to print the scores using StandardNaiveBayesClassifier and ComplementaryNaiveBayesClassifier in a binary classification problem and see no difference between the scores, so it seems complementary naïve bayes is completely disabled.
