-----------------------------------
Multi-class is just binary with n=2. It's trivial to do binary classification.
> Binary classification using Naive bayes

> spark naive bayes does not support for binary classification . I checked with
> both ML and MLLIB . According to current scenario Naive bayes only support
> multi class classification . We have to write code for binary classification
> also .As we know logistic regression support binary classification .
