= Naive Bayes Classifier

This is an extremely simple, straight forward Naive Bayes implementation.

== Install

gem sources -a -http://gemcutter.org sudo gem install naive_bayes

== How To Use

require 'rubygems' require 'naive_bayes'

a = NaiveBayes.new(:spam, :ham)

a.train(:spam, 'bad', 'word') a.train(:ham, 'good', 'word')

b = "this is a bad sentence".split(' ')

a.classify(*b) #=> [:spam, 0.03125]

You can also tell your classifier to save itself, so its easy for you to pick up where you left off:

require 'rubygems' require 'naive_bayes'

a = NaiveBayes.new(:spam, :ham) a.db_filepath = 'path/to/anywhere.nb'

a.train(:spam, 'bad', 'word') a.train(:ham, 'good', 'word')

a.save

Some time goes past and we want to classify a new document we just received...

require 'rubygems' require 'naive_bayes'

a = NaiveBayes.load('path/to/file')

b = "this is a bad sentence".split(' ')

It's as if we were never apart

a.classify(*b) #=> [:spam, 0.03125]
