Implicit Alternating Least Squares SVD
--------------------------------------
Key: MAHOUT-737
URL: https://issues.apache.org/jira/browse/MAHOUT-737
Project: Mahout
Issue Type: Improvement
Reporter: Tamas Jambor
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).
