A convertible, t motone r anti-motone r succinct constraint cant be pushed deep into the an Apriori mining algorithm Within the level wise framework, direct pruning based on the constraint can be made Itemset df violates constraint C: avg(x)>=25 Since adf satisfies C, Apriori needs df to assemble adf, df cant be pruned But it can be pushed into frequent-pattern growth framework!
