--------------------------------------
Jake, I've run the new version without an error and checked a few documents if
they are related with the inferred topics.
It works for me.
> InMemoryCollapsedVariationalBayes0 to load input vectors with docIDs

> Key: MAHOUT-1051
> URL: https://issues.apache.org/jira/browse/MAHOUT-1051
> Project: Mahout
> Issue Type: Improvement
> Components: Clustering
> Affects Versions: 0.8
> Reporter: Gokhan Capan
> Priority: Minor
> Labels: cvb, lda
> Fix For: 0.8
>
> Attachments: MAHOUT-1051.patch, MAHOUT-1051.patch
>
>
> Based upon our conversation with Jake in the user-list, I have modified the
> o.a.m.clustering.lda.cvb.InMemoryCollapsedVariationalBayes0.loadVectors so
> that it does not ignore document ids in input. To preserve backwards
> compatibility, it behaves as it did earlier if a ClassCastException is
> thrown; which occurs when ids are not integers, and/or the document vector
> (or getDelegate() if it is a NamedVector) cannot be cast to a
> RandomAccessSparseVector.
