Joseph K. Bradley resolved SPARK-5567. -------------------------------------- Resolution: Fixed Fix Version/s: 1.5.0 Issue resolved by pull request 7760 [https://github.com/apache/spark/pull/7760] > 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 > Fix For: 1.5.0 > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
