Apache Spark reassigned SPARK-23568: ------------------------------------ Assignee: Apache Spark > Silhouette should get number of features from metadata if available > ------------------------------------------------------------------- > > Key: SPARK-23568 > URL: https://issues.apache.org/jira/browse/SPARK-23568 > Project: Spark > Issue Type: Improvement > Components: ML > Affects Versions: 2.4.0 > Reporter: Marco Gaido > Assignee: Apache Spark > Priority: Minor > > In Silhouette computation we need to know the number of features. This is > done taking the first row and checking the size of the features vector. > Despite it works fine, if the number of attributes is present in the metadata > of the column, we can avoid the additional job which is generated by using > `first`. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
