Subject [jira] [Created] (SPARK-23742) Filter out redundant AssociationRules
Date Mon, 19 Mar 2018 21:17:00 GMT
Joseph K. Bradley created SPARK-23742:
-----------------------------------------

             Summary: Filter out redundant AssociationRules
                 Key: SPARK-23742
                 URL: https://issues.apache.org/jira/browse/SPARK-23742
             Project: Spark
          Issue Type: Improvement
          Components: ML
    Affects Versions: 2.3.0
            Reporter: Joseph K. Bradley


AssociationRules can generate redundant rules such as:
* (A) => C
* (A,B) => C  (redundant)

It should optionally filter out redundant rules.  It'd be nice to have it optional (but maybe
defaulting to filtering) so that users could compare the confidences of more general vs. more
specific rules.
