粗集理论在调查数据可信度评判中的应用OA北大核心CSCDCSTPCD
APPLYING ROUGH SET THEORY IN CREDIBILITY JUDGEMENT OF SURVEY DATA
在教育领域中常常会进行教学评价、学习评价等调查活动,而学生填写的数据有很大的随意性.为评判调查数据的可信度,引入粗集理论,先对属性集合进行初步约简,再利用条件属性的重要度确定约简中各属性权重,最后由模糊评判方法来衡量调查数据的可信度.其中,模糊关系矩阵由选择可信度来确定.实例分析结果表明,该方法是可行的、有效的.

For the judgement of the credibility of survey data, the rough set theory is introduced. First, a primary reduction is conducted on the attributes set, and then each attribute weight is confirmed according to the significance degree of condition attributes. At last the…查看全部>>
