# Weka

[![Gem Version](https://badge.fury.io/rb/weka.svg)](http://badge.fury.io/rb/weka)
[![Travis Build](https://travis-ci.org/paulgoetze/weka-jruby.svg)](https://travis-ci.org/paulgoetze/weka-jruby)

Machine Learning & Data Mining with JRuby based on the [Weka](http://www.cs.waikato.ac.nz/~ml/weka/index.html) Java library.

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'weka'
```

And then execute:

    $ bundle install

Or install it yourself as:

    $ gem install weka

## Usage

Use Weka's Machine Learning and Data Mining algorithms by requiring the gem:

```ruby
require 'weka'
```

The weka gem tries to carry over the namespaces defined in Weka and enhances some interfaces in order to allow a more Ruby-ish programming style when using the Weka library.

The idea behind keeping the namespaces is, that you can also use the [Weka documentation](http://weka.sourceforge.net/doc.dev/) for looking up functionality and classes.

Please refer to [the gem’s Wiki](https://github.com/paulgoetze/weka-jruby/wiki) for
detailed information about how to use weka with JRuby and some examplary code snippets.

## Development

After checking out the repo, run `bin/setup` to install dependencies.
To install this gem onto your local machine, run `bundle exec rake install`.

Then, run `rake spec` to run the tests. You can also run `bin/console` or `rake irb` for an interactive prompt that will allow you to experiment.

## Acknowledgement

The original ideas for wrapping Weka in JRuby come from [@arrigonialberto86](https://github.com/arrigonialberto86) and his [ruby-band](https://github.com/arrigonialberto86/ruby-band) gem. Great thanks!
