In addition, an effective method is proposed to select the β-reducts. First, we calculate a precision parameter value to obtain the subsets of information system that are based on the least upper bound of the data misclassification error. Next, we measure the quality of classification and remove redundant attributes from each subset.
本论文也提出一个根据精确参数来选择最简化集合的方法,这方法首先利用资料错误率的最小上界来决定精确参数值,并利用所获得的精确参数值来寻找资讯系统的子集合;接著计算每一个子集合的分类品质并利用分类品质的量测移除子集合中多余的属性,而删除多余属性的子集合即β的最简化属性集合。
