Mahout contains a long list of them, which you can still use. However in about 2013 there was a revolution in recommenders, which favored what we might call âMultimodalâ, meaning they could take in data of all sortsâbasically anything we might think was an indicator of user taste. The new Samsara algorithm, called Correlated Cross-Occurrence (CCO) is just such a next gen recommender algorithm but Mahout-Samsara only implements the model building part.
