| Abstract: | In this paper,variable precision rough set model based on the most similar type is researched.In this model,the basis of the variable precision rough set is expanded to conditions similar to the relationship between the weak form the equivalence relation,makes better use of data between the relevant information,the expansion the rough set theory applications.The nature and attribute reduction about the similar variable precision rough set is discussed,examples of similar variable precision rough set in data... |
