myrrix-recommender

Myrrix is a complete, real-time, scalable recommender system, evolved from Apache Mahout™. Just as we take for granted easy access to powerful, economical storage and computing today, Myrrix will let you take for granted easy access to large-scale learning from data. The Serving Layer component ... [More] of Myrrix is open source, and can even function as a stand-alone system suitable for moderate scale. This project hosts the open source Serving Layer from Myrrix. [Less]
