C# Class MyMediaLite.RatingPrediction.BiPolarSlopeOne

Bi-polar frequency-weighted Slope-One rating prediction

Daniel Lemire, Anna Maclachlan: Slope One Predictors for Online Rating-Based Collaborative Filtering. SIAM Data Mining (SDM 2005) http://www.daniel-lemire.com/fr/abstracts/SDM2005.html This recommender does NOT support incremental updates. They would be easy to implement, though.
