Singular rough sets (S-rough sets) have three classes of forms:one-directional S-rough sets,dual of one- directional S-rough sets,and two-directional S-rough sets.Dynamic,hereditary,mnemonic,and hiding properties are the basic characteristics of S-rough sets.By using the S-rough sets,the concepts of f-hiding knowledge,F-hiding knowledge,hiding degree,and hiding dependence degree are given.Then,both the hiding theorem and the hiding dependence theorem of hiding knowledge are proposed.Finally,an application of hiding knowledge is discussed. Two sets of one-directional S-rough sets, and two-directional S-rough sets. Dynamic, hereditary, mnemonic, and hiding properties are the basic characteristics of S-rough sets.By using the S-rough sets, the concepts of f-hiding knowledge, F-hiding knowledge, hiding degree, and hiding dependence degree are given.Then, both the hiding theorem and the hiding dependence theorem of hiding knowledge are proposed .Finally, an application of hiding knowledge is discussed.
