| Abstract: | Attribute reduction is one of the key problems of rough set.In this paper,some relative conclusions of attribute reduction and definition of attribute significance were proposed based on decision rule.This paper also gives heuristic algorithm,which used golden-section thinking to improve algorithm efficiency.The algorithm efficiency and correctness have been illustrated with an example. |
