[jira] [Created] (MAHOUT-861) Simultaneously update left and right
vectors while training ExpectationMaximizationSVDFactorizer
Simultaneously update left and right vectors while training ExpectationMaximizationSVDFactorizer
------------------------------------------------------------------------------------------------
Key: MAHOUT-861
URL: https://issues.apache.org/jira/browse/MAHOUT-861
Project: Mahout
Issue Type: Bug
Components: Collaborative Filtering
Affects Versions: 0.6
Reporter: Gokhan Capan
Assignee: Sean Owen
Priority: Minor
I guess the updates on left and right vectors in ExpectationMaximizationSVDFactorizer#train(int i, int j, int f, SVDPreference pref) should be done simultaneously according to the original algorithm (http://sifter.org/~simon/journal/20061211.html)
