Nakul Jindal commented on SPARK-11439: -------------------------------------- Thanks [~lewuathe]. I've also updated the comment in the LinearRegressionSuite.scala file with an R snippet to reproduce the results. > Optimization of creating sparse feature without dense one > --------------------------------------------------------- > > Key: SPARK-11439 > URL: https://issues.apache.org/jira/browse/SPARK-11439 > Project: Spark > Issue Type: Improvement > Components: ML > Reporter: Kai Sasaki > Priority: Minor > > Currently, sparse feature generated in {{LinearDataGenerator}} needs to > create dense vectors once. It is cost efficient to prevent from generating > dense feature when creating sparse features. -- 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
