| 摘 要： | 为提高心血管功能计算机辅助诊断的可靠性,将粗糙集引入到心血管功能的计算机诊断中。通过对获取的参数进行统计分析,建立条件属性表、决策属性表和决策表;通过利用粗糙集相关矩阵,采用贪婪策略构造的寻找最小属性约简的启发式算法,对条件属性进行约简并建立相应的决策表和规则集。大量实例分析诊断表明,该方法确能提高机器辅助诊断心血管功能的正确性并且较容易实现。

| Abstract: | In order to improve the reliability of cardiovascular function diagnosis by computer,the rough set was introduced.The condition attribution table and decision table were set up by analysing parameters obtained by computer and the reductionn of the condition attribution table was obtained by using the relation matrix of rough set and greedy strategy.The study of lots of case show that this method can improve the reliability of cardiovascular function diagnosis by compter and can be realized easily. |
