LibRec is a Java library for recommender systems (Java version 1.7 or higher required). It implements a suit of state-of-the-art and up-to-date recommendation algorithms. It consists of three major components: Generic Interfaces, Data Structures and Recommendation Algorithms. To learn more, check out the home page, or look into the detailed tutorial.
- Cross-platform: as a Java software, LibRec can be easily deployed and executed in any platforms, including MS Windows, Linux and Mac OS.
- Fast execution: LibRec runs much faster than other libraries, and a detailed comparison over different algorithms on various datasets is available via here.
- Easy configuration: LibRec configs recommenders using a configuration file: librec.conf.
- Easy expansion: LibRec provides a set of well-designed recommendation interfaces by which new algorithms can be easily implemented.
- Baseline: GlobalAvg, UserAvg, ItemAvg, Random, Constant, MostPop
- Rating Prediction: UserKNN, ItemKNN, RegSVD, PMF, SVD++, BiasedMF, BPMF, SocialMF, TrustMF, SoRec, SoReg, RSTE
- Item Ranking: BPRMF, CLiMF, RankALS, RankSGD, WRMF
- Extension: NMF, SlopeOne, Hybrid, PD, AR, PRankD
