Indiscernibility Relation, Rough Sets and Information Systemf some equivalence relations in knowledge base and then it is also an equivalence relation. This chapter introduced the basic concepts of Pawlak’s rough set, Ziarko’s variable precision rough set and Qian’s multigranulation rough sets. These models were all proposed on the basis of indiscernibility
