Xiangrui Meng updated SPARK-4596: --------------------------------- Assignee: DB Tsai > Refactorize Normalizer to make code cleaner > ------------------------------------------- > > Key: SPARK-4596 > URL: https://issues.apache.org/jira/browse/SPARK-4596 > Project: Spark > Issue Type: Improvement > Components: MLlib > Reporter: DB Tsai > Assignee: DB Tsai > Fix For: 1.2.0 > > > In this refactoring, the performance is slightly increased by removing the > overhead from breeze vector. The bottleneck is still in breeze norm which is > implemented by activeIterator. This inefficiency of breeze norm will be > addressed in next PR. At least, this PR makes the code more consistent in the > codebase. -- 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
