项目集发生变化的关联规则增量式更新算法

Incremental updating algorithms of mining association rules for itemsets changed

从项目集发生变化的角度考虑数据库的增量式更新问题,并有效的改进了著名的FUP算法,提出了项目集发生变化的快速增量式更新算法FUPIC(FastUPdatealgorithmforItemsetsChanged)。

The incremental updating problem with itemsets changed was discussed. The famous Fast Update Algorithm was improved and the new fast update algorithm for itemsets changed, which was significant to new products on sales was presented.
