摘要
对动态约简的思想进行了阐述.详细分析了其中子表抽取的有关问题,指出了存在的不足.给出了一种新的计算动态约简子表族大小的方法和几个评估动态约简样本族的参数.实验证明了算法的有效性.*
The thought of dynamic reduct is described, its sub-table extraction problem is analyzed in detail, and the shortage is pointed out. A new algorithm is given to calculate the size of the dynamic reduct sub-table family, and some parameters are also presented to evaluate the dynamic reduct sampling family. Experiment analysis shows that algorithm is efficient.
