Takeshi Yamamuro commented on SPARK-23742:
------------------------------------------

Can't we control this case by a new config implemented in SPARK-24802?

> 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.
