We have a class called SVDRecommender that takes a Factorizer as input. Each implementation of a Factorizer corresponds to an algorithm, we have biased matrix factorization, SVD++ and two different ALS implementations. > I found both > KnnItem and TreeClustering are deprecated on the newest version of Mahout > (0.8-SNAPSHOT) ? Why is this the case? We are not aware of anyone using these algorithms, that's why we chose to deprecate them.
