Xiangrui Meng closed SPARK-3820. -------------------------------- Resolution: Won't Fix > Specialize columnSimilarity() without any threshold > --------------------------------------------------- > > Key: SPARK-3820 > URL: https://issues.apache.org/jira/browse/SPARK-3820 > Project: Spark > Issue Type: Improvement > Components: MLlib > Reporter: Xiangrui Meng > Assignee: Reza Zadeh > > `RowMatrix.columnSimilarities` calls `RowMatrix.columnSimilarity(0.0)` to > compute the exact cosine similarities. It still requires sampling, which is > unnecessary for this case. We should have a specialized version for it, in > order to have a fair comparison with DIMSUM. -- 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
