1、粗糙集在医疗诊断中的应用研究摘要：为了提高医疗诊断效率，缓解医院人才短缺的压力，将粗糙集应用于医疗诊断中。分析了医疗诊断研究目的及意义，以及医疗诊断和粗糙集理论的发展现状。将广西壮族自治区一医院中的真实病例作为研究对象。分析了粗糙集基本知识，对不同疾病特征进行选择，通过基于信息熵的离散算法对连续数据进行离散处理，结合约简算法，制成理想的分类器，完成精确的分类。将粗糙集方法应用于广西一医院中风湿病诊断中风湿病的诊断中，给出具体实例。结果表明，将粗糙集应用于医疗诊断后，能够有效提高医疗诊断，且可保证医疗诊断的可靠性。关键词：粗糙集；医疗；诊断；病历Application of rough set

2、in medical diagnosisAbstract: in order to improve the efficiency of medical diagnosis and alleviate the shortage of talent in hospital, rough set is applied to medical diagnosis. The purpose and significance of medical diagnosis research, and the development of medical diagnosis and rough set theory

3、 are analyzed. The real cases in a hospital in the Guangxi Zhuang Autonomous Region were taken as subjects. Analysis of the basic knowledge of rough set, the selection of different diseases characterized by discrete algorithm based on information entropy of continuous data discretization, combined with the reduction algorithm, made the ideal classifier, accurate classification. The rough
