Hi Sean,

Thank you for you reply! Would you mind if I ask for the reasons why Spark is not interested
in HDP?

>                 Key: SPARK-8555
>                 URL: https://issues.apache.org/jira/browse/SPARK-8555
>             Project: Spark
>          Issue Type: New Feature
>          Components: MLlib
>            Reporter: yuhao yang
>            Priority: Minor

> The task is created for exploration on the online HDP algorithm described in
> http://jmlr.csail.mit.edu/proceedings/papers/v15/wang11a/wang11a.pdf.
> Major advantage for the algorithm: one pass on corpus, streaming friendly, automatic
K (topic number).
> Currently the scope is to support online HDP for topic modeling, i.e. probably an optimizer
for LDA.
