To make rough set theory can deal with incomplete information system with noise effectively,combining the generalized rough set model based on set pair situation with the majority inclusion relation proposed by professor Ziarko,the variable precision set pair situation rough set model is proposed.Then the definition of positive region similarity is given.A heuristic attribute reduction algorithm based on positive region similarity is presented.The time complexity of the algorithm is analyzed… CONTINUE READING
