> Key: MAHOUT-1124
> URL: https://issues.apache.org/jira/browse/MAHOUT-1124
> Project: Mahout
> Issue Type: Task
> Components: Collaborative Filtering
> Affects Versions: 0.8
> Reporter: Sebastian Schelter
> Assignee: Sean Owen
> Fix For: 0.8
>
>
> Deprecating some recommenders for the following reasons:
> org.apache.mahout.cf.taste.impl.recommender.svd.FunkSVDFactorizer
> RatingSGDFactorizer should be learning faster and has a nicer model as
> it includes user/item biases
> org.apache.mahout.cf.taste.impl.recommender.svd.ImplicitLinearRegressionFactorizer
> Seems to be using the same model as ALSWRFactorizer, however there are
> no tests and ALSWR can handle more explicit and implicit feedback
> org.apache.mahout.cf.taste.impl.recommender.TreeClusteringRecommender
> org.apache.mahout.cf.taste.impl.recommender.TreeClusteringRecommender2
> org.apache.mahout.cf.taste.impl.recommender.knn
> I don't recall anybody using those or asking about them the last years.
