摘要
介绍了目前关联规则挖掘中效率较高的FP-growth算法,并对FP-growth算法中存在的几点不足进行了相应的改进,改进后的算法从时间性能和空间性能两方面都得到了很大的提升。
This paper describes the FP-growth algorithm-one of the most efficient algorithm among al the association rule algo-rithms,and makes up for several deficiencies exist in FP-growth algorithm.The optimized algorithm improve the efficiency of the algorithm in time as wel as space.
