= 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]
