Abstract


This article chooses in data mining, the attribute reduction as the research object, using rough set theory, this paper puts forward a higher efficiency of genetic reduction algorithm, can quickly find the system minimum reduction or time small reduction; Based on the classification subsystem of the attribute reduction method, the decision-making system is divided into several child decision-making system to achieve the minimum reduction system, analyzes and proves that the system of minimum reduction and reduction of each subsystem, the relationship between the set is given of the subsystems of the reduction structure system minimum reduction method, and proved that the method is completeness. Finally, this paper gives two algorithm each given a reduction examples.
