Tamas Jambor commented on MAHOUT-737:
-------------------------------------
Sebastian,
yes, it is based on that paper. the changes look good. I can run it on my
implicit dataset I wrote the code originally, but cannot really share the
results. or alternatively we could run it on this last.fm data

> 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).
