【Abstract】 This paper first introduces the online association rule mining algorithm named Carma presented by Christian Hidber,and then proposes some improvements of this algorithm.We weaken the condition of inserting a subset v of cur-rent transaction in lattice of potentially large itemsets V.We modify the expression of maxMissed to make the calculation more simple.Experiments showthe improvements speed up the algorithm.更多还原
