Hyukjin Kwon resolved SPARK-23740. ---------------------------------- Resolution: Incomplete > Add FPGrowth Param for filtering out very common items > ------------------------------------------------------ > > Key: SPARK-23740 > URL: https://issues.apache.org/jira/browse/SPARK-23740 > Project: Spark > Issue Type: Improvement > Components: ML > Affects Versions: 2.3.0 > Reporter: Joseph K. Bradley > Priority: Major > Labels: bulk-closed > > It would be handy to have a Param in FPGrowth for filtering out very common > items. This is from a use case where the dataset had items appearing in > 99.9%+ of the rows. These common items were useless, but they caused the > algorithm to generate many unnecessary itemsets. Filtering useless common > items beforehand can make the algorithm much faster. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
