[jira] [Updated] (SPARK-9231) DistributedLDAModel method for top topics per document

["Joseph K. Bradley (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SPARK-9231?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Joseph K. Bradley updated SPARK-9231:
-------------------------------------
    Description: 
Helper method in DistributedLDAModel of this form:
{code}
/**
 * For each document, return the top k weighted topics for that document.
 * @return RDD of (doc ID, topic indices, topic weights)
 */
def topTopicsPerDocument(k: Int): RDD[(Long, Array[Int], Array[Double])]
{code}

I believe the above method signature will be Java-friendly.
