Sebastian Schelter commented on MAHOUT-737:
-------------------------------------------
I concur, the goal should definitely be to have interchangeable implementations
of our Factorizer interface that can all be used with SVDRecommender, so our
users can pick the implementation that works best for them in their usecase.

> I am sharing this Java implementation of mine that is based on the paper -
> Collaborative Filtering with Implicit Datasets. The implementation is
> multi-treading and can be easily extended to use it on Hadoop. In fact this
> approach would possibly work with non-implicit datasets, but further testing
> is needed. The algorithm is tried and tested on an implicit TV-viewing
> dataset, and the performance was pretty good (details to follow).
