RSAlgorithms

Recently, we have launched an open source project RSAlgorithms, which provides an integrated training and testing framework. In this framework, we implement a set of classical traditional recommendation methods which make predictions only using rating data and social recommendation methods which utilize trust/social information in order to alleviate the sparsity of ratings data. Besides, we have collected some classical methods implemented by others for your convenience.
