Weichen Xu created SPARK-16499: ---------------------------------- Summary: Improve applyInPlace function for matrix in ANN code Key: SPARK-16499 URL: https://issues.apache.org/jira/browse/SPARK-16499 Project: Spark Issue Type: Improvement Components: ML, MLlib Reporter: Weichen Xu
The ApplyInPlace function in ANN code: ` def apply(x: BDM[Double], y: BDM[Double], func: Double => Double): Unit ` is implemented using simple while loop. It should be replaced with breeze BDM matrix operating function, so that it can take advantage of breeze lib's optimization. -- 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
