- W2377037977 abstract "In order to resolve the errors of reduction algorithms for the existence of inconsistent objects in the decision table and enhance the efficiency of reduction algorithm,firstly,the definition of simplied decision table is proposed,and it is proved that the core and attribute reduction acquired from the method are equivalent to the core and attribute reduction of original decision table.Then,the notion and characters of the conflict region are given.The features of the core attribute and attribution importance based on the change of the number of conflict objects are studied,and the corresponding algorithms of computing core attributes and attribute importance are designed respectively.On the basis of above,an attribute reduction algorithm based on conflict region decreasing is designed,which time complexity and space complexity of the algorithm are O(|C|~2|U/C|) and O(|U|).Finally,an example and the experimental results show that the algorithm is correct and efficient." @default.
