Joseph K. Bradley resolved SPARK-9788. -------------------------------------- Resolution: Fixed Fix Version/s: 1.5.0 Issue resolved by pull request 8077 [https://github.com/apache/spark/pull/8077] > LDA docConcentration, gammaShape 1.5 binary incompatibility fixes > ----------------------------------------------------------------- > > Key: SPARK-9788 > URL: https://issues.apache.org/jira/browse/SPARK-9788 > Project: Spark > Issue Type: Improvement > Components: MLlib > Reporter: Joseph K. Bradley > Assignee: Feynman Liang > Fix For: 1.5.0 > > > From [SPARK-9658]: > 1. LDA.docConcentration > It will be nice to keep the old APIs unchanged. Proposal: > * Add “asymmetricDocConcentration” and revert docConcentration changes. > * If the (internal) doc concentration vector is a single value, > “getDocConcentration" returns it. If it is a constant vector, > getDocConcentration returns the first item, and fails otherwise. > 2. LDAModel.gammaShape > This should be given a default value. -- 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
