摘要
提出了几种组合粒下的粗糙集模型,并将其与单一粒下的粗糙集进行了比较,同时与粒逻辑运算下的粗糙集模型进行了比对,创造性地得到了组合粒、单一粒以及粒逻辑运算下的粗糙集模型之间的关系。结果表明,组合粒与粒逻辑运算组成了一个链结构,这为研究基于信息粒的知识获取以及动态粒的推理奠定了基础。
This paper proposed the rough set model under combination granule,and compared it with that under single granular,also with rough set model under logical computing of granule,which contributed to the relationship between rough set models under combination granule,singular granules and logical computing of granules.Results show that combination granule and logical computing of granule construct a chain,which will lay a foundation for knowledge acquisition based on information granule and induction based on dynamic granule.
