             Summary: Add rule counts to assoc_rules results
                 Key: MADLIB-1044
                 URL: https://issues.apache.org/jira/browse/MADLIB-1044
             Project: Apache MADlib
          Issue Type: Improvement
          Components: Module: Association Rules
            Reporter: Afshin Rahimi


The association rules modules works great but it could be improved by showing the count of candidates besides support.

count = support * num_transactions

The reason is that within the business you need to show the significance of a rule but you won't be able to do it just by support while you can do it by count (The number of times two items co-occured).

One can manually multiply the number of transactions by support but working with big data, you need to compute the count first and then create a query over the assoc_rules result table to do the multiplication.

It would be very nice to have the count within the assoc_rules table itself.
