| Abstract: | According to the practical situation that more accurate information is required in the process of information communication,using two-direction S-rough sets theory,a new dynamic rough communication model is proposed,i.e.two-direction S-lower approximation dynamic rough communication model.Its properties are discussed,and the relationships between information invariability and knowledge,between information loss and knowledge are obtained.A method of improving dynamic rough communication accuracy is presented.In the end,an application of the model is given. |
