【摘要】 在教学评估过程中,采用粗集理论的属性约简算法可以优化指标评价体系,剔出冗余指标。该方法根据区分矩阵原理构建属性频率函数,进而分析出关键性指标。算例结果显示,根据选出的5个指标依然有很高的分类质量和分类精度,证明了该方法是可行的。更多还原

【Abstract】 It’s difficult to estimate teaching quality with too many indexes in the teaching estimation system.Some indexes are redundant.The paper introduces reduction algorithm of attributes based on rough set theory to extract important indexes. According to the reduction,a new decision table is built and the result shows the classification quality and classification accuracy are high.So the method is feasible.更多还原
