Yanbo Liang commented on SPARK-17134: ------------------------------------- This is interesting. We also trying to use BLAS to accelerate linear algebra operations in other algorithms such as {{KMeans/ALS}} and I have some basic performance test result. I would like to contribute to this task. Thanks! > Use level 2 BLAS operations in LogisticAggregator > ------------------------------------------------- > > Key: SPARK-17134 > URL: https://issues.apache.org/jira/browse/SPARK-17134 > Project: Spark > Issue Type: Sub-task > Components: ML > Reporter: Seth Hendrickson > > Multinomial logistic regression uses LogisticAggregator class for gradient > updates. We should look into refactoring MLOR to use level 2 BLAS operations > for the updates. Performance testing should be done to show improvements. -- 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
