Joseph K. Bradley updated SPARK-8536:
-------------------------------------
Description:
Several users have requested LDA using asymmetric priors, including learning
those hyperparameters. We should add this functionality.
Note that it could be added to EM, online LDA, or both. I suggest adding it to
online LDA initially, followed by EM in a separate PR.
This JIRA is now limited to the document-topic prior (docConcentration). See
linked JIRA for topicConcentration, which is lower priority.
