# How to validate Association Role Mining

I have used apriori to mine roles on a training set and the result is similar to the below

I have been looking around for a kind of validation or measure of such association but it seems pretty vague and there no specific method yet, I come across an opinion which suggests using precision which is defined as TP / TP + FP my questions are

• is using precision would be a sufficient ?
• is it correct to assume that ...
• TP = transactions having both A and B
• FP = transactions not containing A and B + transcation not containig A + transactions not containing B
• would I just calculate the coinefidence on the test set ?
