Sebastian Schelter commented on MAHOUT-737:
-------------------------------------------

It would be great if you could run it on your proprietary dataset and simply tell if you get
reasonable results.

> 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).
