【摘要】 为了有效挖掘一阶谓词逻辑规则,提出了一种基于基因表达式编程(GEP)技术的挖掘算法:PHVB算法。提出了规范一阶谓词规则概念;设计了量词隐含、变元绑定策略,将一阶谓词规则挖掘问题转化为GEP算法能够解决的形式;提出了基于GEP的一阶谓词逻辑规则挖掘算法PHVB算法。实验结果表明,采用PHVB算法可以有效发现一阶谓词关联规则。更多还原

【Abstract】 In order to mining the first-order predicate logic rule effectivly,a novel first-order predicate logic rule mining algorithm,named PHVB algorithm,was proposed based on Gene Expression Programming(GEP).The main contributions includes:A new formal concept of the first-order predicate logic rule was proposed;two strategies,quantifier-free strategy and variables bounding strategy,which make it easy to deal with the first-order predicate logic rule mining with GEP,were proposed;a novel first-order predicate rule mining algorithm,named PHVB algorithm,was proposed.Extensive experiments demonstrated that the feasibility and the efficiency of PHVB is high.更多还原
