Sebastian is working on this
> Remove old LDA implementation from codebase
> -------------------------------------------
>
> Key: MAHOUT-1009
> URL: https://issues.apache.org/jira/browse/MAHOUT-1009
> Project: Mahout
> Issue Type: Improvement
> Components: Clustering
> Affects Versions: 0.7
> Reporter: Jake Mannix
> Assignee: Sebastian Schelter
> Priority: Minor
> Fix For: 0.7
>
>
> The old LDA is unmaintained and unsupported. We already (since 0.6) have a
> newer, faster version in the o.a.m.clustering.lda.cvb package, which I'm
> actively working on and using in production at Twitter. We should delete the
> old o.a.m.clustering.lda codebase.
> Normally, I'd say that we should at the same time promote
> o.a.m.clustering.lda.cvb up a package-level, but that would cause some
> serious merge conflicts on my GitHub branch (with updates/improvements/new
> features targetted for 0.8), so we can get users on this new code by simply
> changing the driver.classes.props to have "lda" point to CVB0Driver as the
> main().
> One thing which goes away entirely, is the LDAPrintTopics class, but it's
> replaced by simply doing VectorDumper with the -sort option on the model
> files, which is more standard anyways.
