----------------------------------
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.
