| Abstract: | Based on one direction S-rough sets(one direction singular rough sets), dual of one direction S-rough sets(dual of one direction singular rough sets), the concepts and structures of S-rough equivalent classes, dual of S rough equivalent classes and rough equivalent classes are proposed. The relationship among the three kinds of equivalent classes is analysed. And attribute theorems and dynamic separate theorems about S-rough equivalent classes and dual of S-rough equivalent classes are obtained. Finally, theories about dual of S rough equivalent classes given in the paper are applied to knowledge dynamic mining-discovery. |
