Ruby library for interfacing with FANN (Fast Artificial Neural Network)

RubyFann, or "ruby-fann" is a Ruby Gem (no Rails required) that binds to FANN (Fast Artificial Neural Network) from within a ruby/rails environment. FANN is a is a free native open source neural network library, which implements multilayer artificial neural networks, supporting both fully-connected and sparsely-connected networks. It is easy to use, versatile, well documented, and fast. RubyFann makes working with neural networks a breeze using ruby, with the added benefit that most of the heavy lifting is done natively.A talk given by our friend Ethan from Big-Oh Studios at Lone Star Ruby 2013: http://confreaks.com/videos/2609-lonestarruby2013-neural-networks-with-rubyfann.
