Granular association rules reveal patterns hide in many-to-many relationships which are common in databases. An example of such rules might be "40% men like at least 30% kinds of alcohol; 45% customers are men and 6% products are alcohol." Mining all rules satisfying four thresholds is a challenging problem due to pattern explosion. In this paper, we propose a new type of parametric rough sets on two universes to study this problem. The model is deliberately defined such that the parameter corresponds to one threshold of rules. With the lower approximation operator in the new parametric rough sets, a backward algorithm is designed to deal with the rule mining problem. Experiments on a real world dataset show that the new algorithm is significantly faster than the existing sandwich algorithm. This study builds connections among granular computing, association rule mining and rough sets.
