Subject: Naive-Bayes work flow


Efficiency is not normally a term used with classifiers.  Can you define it?

>From you confusion matrix, it looks like nearly all of your documents are
being classified into one class.  That usually indicates that there is some
fundamental formatting difference between your original training data and
your test data.

Without being able to see any of your data or the output of your training
run, it is impossible to say more.
