Description:

MyMediaLite is a lightweight, multi-purpose library of recommender system algorithms.

It addresses the two most common scenarios in collaborative filtering: - rating prediction (e.g. on a scale of 1 to 5 stars), and - item prediction from implicit feedback (e.g. from clicks or purchase actions).

MyMediaLite gives you a choice of many recommendation methods: - dozens of different recommender engines - methods can use collaborative and attribute/content data

MyMediaLite is ready to use: - MyMediaLite includes evaluation routines for rating prediction and item prediction; it can measure MAE, RMSE, AUC, prec@N, MAP, NDCG. - It also comes with command line tools for both tasks that read a simple text-based input format.

MyMediaLite is compact: The core library has a size of less than 100KB.

Portability: Written in C#, for the .NET platform; runs on every architecture supported by Mono: Linux, Windows, Mac OS X.

Freedom: MyMediaLite is free software/open source software. It can be used, modified, and distributed under the terms of the GNU General Public License (GPL).

Additional features: - Serialization: save and reload recommender engine models - Real-time online updates for many recommender engines
