Summary: Parallelize YtransposeY in
ImplicitFeedbackAlternatingLeastSquaresSolver
Key: MAHOUT-1429
URL: https://issues.apache.org/jira/browse/MAHOUT-1429
Project: Mahout
Issue Type: Improvement
Components: Collaborative Filtering
Affects Versions: 0.9
Reporter: Adam Ilardi
Priority: Minor
I wrote a simple patch to do the calculation in threads. It could be better but
it gets the job done. Is there some other (Matrix transpose dot matrix) code in
mahout that is already parallel? I will reuse that if it exists.
