Comparison of rough set model under granular computing
粒计算下的粗糙集模型比较

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.
