摘要
发现频繁项目集是关联规则数据挖掘中的关键问题。随着数据集的增减,就会产生不同的频繁项目集。在数据集变化情况下频繁项目集的快速高效更新问题仍亟待解决。
Discovering frequent itemsets is important in data mining association rules.With the addition and subtraction of the data sets,there are different frequent itemsets.It attemps to looking for a solution to solve the problem that maintains the renewal of frequent itemsets fastly and efficiently under the variance of data sets.
