class NaiveBayes extends Serializable with Logging
Trains a Naive Bayes model given an RDD of (label, features)
pairs.
This is the Multinomial NB (see here) which can handle all kinds of discrete data. For example, by converting documents into TF-IDF vectors, it can be used for document classification. By making every vector a 0-1 vector, it can also be used as Bernoulli NB (see here). The input feature values must be nonnegative.
