基于交易清单的关联规则挖掘

Association Rule Mining Based On Trade List

Sanober Shaikh, Madhuri rao

摘要:

提出了一种基于频繁项集的挖掘算法。Apriori算法每次发现频繁项集时都要扫描数据库,因此非常耗时,而且每一步都要生成候选项集。在无向项集图中,它是对先验知识的改进,但生成树需要时间和空间。定义的算法在开始时只扫描数据库一次,然后从扫描的数据库中生成贸易清单。它包含了整个数据库的信息。它通过考虑最小支持度来寻找频繁项集,并通过考虑最小置信度来生成关联规则。当数据库和最小支持度发生变化时,新算法通过扫描交易列表来发现新的频繁项。因此,与传统算法相比,它的执行效率有了明显的提高。

英文摘要:

In this paper a new mining algorithm is defined based on frequent item set. Apriori Algorithm scans the database every time when it finds the frequent item set so it is very time consuming and at each step it generates candidate item set. So for large databases it takes lots of space to store candidate item set .In undirected item set graph, it is improvement on apriori but it takes time and space for tree generation. The defined algorithm scans the database at the start only once and then from that scanned data base it generates the Trade List. It contains the information of whole database. By considering minimum support it finds the frequent item set and by considering the minimum confidence it generates the association rule. If database and minimum support is changed, the new algorithm finds the new frequent items by scanning Trade List. That is why it's executing efficiency is improved distinctly compared to traditional algorithm.
