+## Naive Bayes
+
+[Naive Bayes](http://en.wikipedia.org/wiki/Naive_Bayes_classifier) are a family of simple 
+probabilistic classifiers based on applying Bayes' theorem with strong (naive) independence 
+assumptions between the features. The spark.ml implementation currently supports both [multinomial
+naive Bayes](http://nlp.stanford.edu/IR-book/html/htmledition/naive-bayes-text-classification-1.html)
+and [Bernoulli naive Bayes](http://nlp.stanford.edu/IR-book/html/htmledition/the-bernoulli-model-1.html).
+More information can be found in the section on [Naive Bayes in MLlib](mllib-naive-bayes.html#naive-bayes-sparkmllib).
