中文摘要：
提出一种新的属性约简算法,该算法基于粗糙集理论认为知识是区分事物的能力的观点,对知识进行了新的量化,并以量化后的区分能力作为启发式信息进行约简,提高了约简效率,理论分析与实例证明该算法是有效的.
英文摘要：
Attribute reduction is an important problem in rough set theory. Based on the viewpoint that attributes have different discernihlity ability in rough set theory, a new attribute reduction algorithm is presented and it quantify knowledge and prove quantify reasonableness, quantified discerniblity ability as heuristic information guiding reduct computation that can improve reduct efficiency. Though running an example,we show that this algorithm is effective.
