theta normalization fo naive bayes is commented out

[tuku <ut...@gmail.com>]

hello;

i searched wiki and the web but couldn't find the reason why theta
normalization is commented out for naive bayes classification.
there is a todo comment on top that states this will be enabled soon.

is there any schedule for this?
do anyone know the reason not to use theta normalization? I am developing
some classifiers using mahout, may be I can manage to get it to work.

best regards.

I believe this was something that was to be fixed when the old Naive Bayes code was replaced by the present implementation.
See Mahout-1001 for more info and history on this.
