TODO: Bayes Classification added to your model

Status: unstable but under development

Travis: Build Status


Add this line to your application's Gemfile:

gem 'acts_as_bayes'

And then execute:

$ bundle

Or install it yourself as:

$ gem install acts_as_bayes


In your Model, add it:

 class Foo
   include Mongoid::Document
   include ActsAsBayes

   field :title, :type=>String, :default=>""
   acts_as_bayes :on=>:title

Now as soon as you update a document, we calculate the frequency of words and then Lorem ipsum dolor sit amet, consectetur clamat pars. Remota et neque ingeniis ipsas. Collegerunt octo summum et invidiosum. Beate ut viderent defensionis procul modo propositum autem, quosdam, animadverti insitam modo beate seditiose nec.

 Foo.create!(:title=>"wow, that is sexy, right?)
 Foo.last.words => [:wow=>1, :sex=>1, :right=>1]

There is a class named BayesCategory. It will be populated automatically. Maybe it would be better to populate it before with train data

if you want to use Map Reduce, you must add to your application.rb:

 config.mongoid.observers = :acts_as_bayes_observer


  • write more tests
  • write a test app using it
  • maybe find a way to use a custom categories model
