The Mahout's side of the story for LDA was resolved as part of this feature request and patch file.
https://issues.apache.org/jira/browse/MAHOUT-458 But the Mahout version I have does not include the options specified in this report. What am I missing? Do I need to download a patch and then recompile Mahout? or download the latest (stable/unstable) version? Have these changes been reverted? If it is the latest version then where can I find it and how can one update the documentation to reflect the changes?
