Abstract
This paper discussed the attribute reduction in rough set theory. By analyzing the common process of reduction algorithm based on the discernibility matrix, a kind of heuristic reduction algorithm utilizing the frequencies of attributes has been presented. According to the application in fault feature extraction of diesel engine, the validity and feasibility of the algorithm was demonstrated.
