Joseph K. Bradley commented on SPARK-7857: ------------------------------------------ Sure, please do! > IDF w/ minDocFreq on SparseVectors results in literal zeros > ----------------------------------------------------------- > > Key: SPARK-7857 > URL: https://issues.apache.org/jira/browse/SPARK-7857 > Project: Spark > Issue Type: Bug > Components: MLlib > Reporter: Karl Higley > Priority: Minor > > When the IDF model's minDocFreq parameter is set to a non-zero threshold, the > IDF for any feature below that threshold is set to zero. When the model is > used to transform a set of SparseVectors containing that feature, the > resulting SparseVectors contain entries whose values are zero. The zero > entries should be omitted in order to simplify downstream processing. -- 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
