【摘要】 Rough集理论提供了一种新的处理不精确、不完全与不相容知识的数学方法。从不一致决策表中快速、有效地挖掘出缺省规则是决策规则挖掘研究的一个热点。该文改进了MDRBR算法,引入了广义支持度概念,并提出了一种基于多元组决策表的缺省规则挖掘算法-MTMDRBR算法,有效地解决了不一致多元组决策表的缺省规则挖掘问题,具有重要的实用意义。更多还原

【Abstract】 Rough Sets theory is a new mathematical method to de al with imprecise,incomplete and inconsistent data.How to efficiently and eff ectively mine default rules is a key focus from inconsistent decision table.Th is paper intro-duces the concept of general support measure,and propose s an algorithm Based on Multi-Tuple decision table for Min-ing Default Rules-MTMDR BR.algorithm MTMDRBR can effectively mine default rules from multi-tuple decis ion table,so the algorithm has real importance.更多还原
