[jira] [Created] (MADLIB-1056) Add filtering options to Apriori to improve performance

Frank McQuillan created MADLIB-1056:
---------------------------------------

             Summary: Add filtering options to Apriori to improve performance
                 Key: MADLIB-1056
                 URL: https://issues.apache.org/jira/browse/MADLIB-1056
             Project: Apache MADlib
          Issue Type: Improvement
          Components: Module: Association Rules
            Reporter: Frank McQuillan
             Fix For: v2.0


Consider adding something like a WHERE clause for LHS and RHS in order to reduce execution time, but still need the existence of the filtered transactions for support and confidence computation. (That is you can't filter them out ahead of time because would skew support and confidence values.)
