摘要
针对传统属性集和依赖度概念的局限性,定义了新的属性集和依赖度概念,通过不同的多属性集依赖度的研究,给出了从属性集依赖度出发求解属性约简和核的方法,即依赖度法,开辟了独立于分辨矩阵法之外又一新途径.研究表明,依赖度法的时空性能比分辨矩阵法更加优越.
Set against the limitations on the traditional attributes and dependability concept, a new concept of attribute sets and dependability was defined . By researching on different kinds of dependability, the solution to resolve the reduct and core attribute was given from the view of attribute sets dependability. That was the method of dependability, which developed another independent new path outside distinguish matrix method. The space - time performance of this method was superior to discernibility matrix＇s.
