How to creating Machine Learning Systems with JRuby

All the different programming languages out there seem to be a better fit for machine learning tasks than Ruby, right?All the different programming languages out there seem to be a better fit for machine learning tasks than Ruby, right? Python has scikit-learn, Java has Weka , and there’s Shogun for machine learning in C , just to name a few. On the other hand, Ruby has an excellent reputation for fast prototyping.So, why shouldn’t you prototype machine learning systems with Ruby? Challenge accepted! In this tutorial, we will build a system that can automatically categorize BBC sports articles for you.Oh, and we’ll do it in Ruby,OK? Well, that’s not entirely true—we will use JRuby and Java’s Weka library via the weka gem.
