Hi,

After using FPG within Mahout, you get raw results like this:

Key: i: Value: ([i],K1), ([i, j],K2), ([l, i],K3), etc...

This means that for the key i, the top associations with i are first i
in K1 transactions, then i and j appears in K2 transactions, etc...

 with K1 > K2 > K3 > ...

Then, you have to use the raw results to measure your associations
rules. You can use several metrics, e.g conviction measure (see
http://en.wikipedia.org/wiki/Association_rule_learning#Alternative_measures_of_interestingness
).

I hope it helped,

Louis
