您要查找的是不是:
- Arrays and bit operation are adopted by the algorithm,the database will not be scanned for many times and the enormous candidate itemsets will not be produced. 该算法采用简单的数组和位运算,在执行关联规则的更新时,既不用多次扫描数据库,也不产生庞大的候选项集。
- The thrice pruning strategy is used in the algorithm, and the number of candidate itemsets and mining time are reduced substantially.The mining efficiency is improved. 该算法采用三种剪枝策略,候选项集数量和挖掘时间明显减少,提高了挖掘效率。
- Unlike Algorithm Apriori our algorithm constructlarge unit submatrix in whole matrix (under certain condition construct maximum unitsubmatrix) and avoid complex process calculating candidate itemset. 这些算法不同于Apriori算法,它们从关注矩阵M满足某种性质的行出发,迭代构造较大全1子阵(在一定条件下能得出最大全1子阵),避开了求候选项目集的复杂过程,使算法成为有效算法。
