    Assignee: Feynman Liang

> Add prediction methods to LDA

>                 Key: SPARK-5567
>                 URL: https://issues.apache.org/jira/browse/SPARK-5567
>             Project: Spark
>          Issue Type: Improvement
>          Components: MLlib
>    Affects Versions: 1.3.0
>            Reporter: Joseph K. Bradley
>            Assignee: Feynman Liang
>   Original Estimate: 168h
>  Remaining Estimate: 168h

> LDA currently supports prediction on the training set.  E.g., you can call 
> logLikelihood and topicDistributions to get that info for the training data.  
> However, it should support the same functionality for new (test) documents.
> This will require inference but should be able to use the same code, with a 
> few modification to keep the inferred topics fixed.
> Note: The API for these methods is already in the code but is commented out.
