The solution is based on Prediction IO platform, which offers a fullstack architecture based on MongoDB database, Hadoop framework for distributed processing, Apache Mahout scalable machine learning library, and RESTful API. We implemented an item-based recommendation engine for product suggestions in an online retail store using realworld data. Preliminary results are quite promising achieving Mean Average Precision of 6 %.
