Methods

train(data[, lambda_])

Train a Naive Bayes model given an RDD of (label, features) vectors.

Methods Documentation

classmethod train(data, lambda_=1.0)

Train a Naive Bayes model given an RDD of (label, features) vectors.

This is the Multinomial NB 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. The input feature values must be nonnegative.

New in version 0.9.0.

Parameters
