[jira] [Commented] (MAHOUT-1519) Remove StandardThetaTrainer

    [ https://issues.apache.org/jira/browse/MAHOUT-1519?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13975306#comment-13975306 ] 

Andrew Palumbo commented on MAHOUT-1519:
----------------------------------------

Will work on this later tonight/tomorrow.  I'll remove StandardThetaTrainer and set the thetaMapper job to only run for CBayes for now.   Will deal with the possibility of optimizing by caching weights in another issue if needed.

> [~Andrew_Palumbo] if I understand your work in MAHOUT-1504 correctly, the theta training is only necessary for complementary naive bayes, right?
> Then, we should remove the StandardthetaTrainer and make the TrainNaiveBayesJob only do the theta training in the complementary case.
> Correct me if I miss something here.
