Apache Spark commented on SPARK-8519: ------------------------------------- User 'yanboliang' has created a pull request for this issue: https://github.com/apache/spark/pull/10306 > Blockify distance computation in k-means > ---------------------------------------- > > Key: SPARK-8519 > URL: https://issues.apache.org/jira/browse/SPARK-8519 > Project: Spark > Issue Type: Improvement > Components: MLlib > Affects Versions: 1.4.0 > Reporter: Xiangrui Meng > Assignee: Apache Spark > Labels: advanced > > The performance of pairwise distance computation in k-means can benefit from > BLAS Level 3 matrix-matrix multiplications. It requires we update the > implementation to use blocks. Even for sparse data, we might be able to see > some performance gain. -- 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
