Mining Efficacious Association Rules Under Length-Decreasing Support Constraint

In mining association rules, Item sets with high-length usually has lower support, but still have potential value. To mine efficacious association rules under long-pattern, a new mining method of efficacious association rules is proposed under length-decreasing support constraint. Compare to other mining methods of association rules, the new method can mine more efficacious long-patterns and improve correlation between the antecedent and the consequent of the rules.
