> 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
> 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.
