title: How to integrate Machine learning into a ruby on rails application
body: <p>Given Python and R have huge machine learning libraries that make it easy to train a machine learning model, and given rails provides a very fast way of building a web app, is there a 'best practice' for integrating a machine learning model (written in python or R) into a rails application? </p>
  
  <p>If so what tools can we use? What are pros and cons of each?</p>
