Abstract:
By means of intersection of covering, two kinds of eovering rough set models are delined in the easeof absenee of equivalenee relations in addition to covering relations between the data elements. The properiesof lower approximation operator and upper approximation operator are diseussed by using comparable methodsin two covering rough set model, and the correetness of the corresponding point is proved by using mathematieal theory. Through analysis of the delinitions of two kinds of covering rough set models, the relationships olthe lower approximation operator and upper approximation operator and with other rough set models are illustra.ted. Through these researches, the rough set theory is expanded, the theory and method of knowledge diseovery is improved, and a simple way is provided for data mining of large databases.
