摘要
为了有效识别大学生心理危机,根据教育统计学理论,采用优势关系分类方法,建立了不完备偏序大学生心理危机预警信息系统的双限制优势粗糙集模型和计算方法。给出了根据信息系统每个属性各自的已知属性值,进行概率分布的计算,选定概率阈值,与已获得的优势概率进行比较,实现对象间的优势关系判断,完成双限制优势关系的分类。并通过改变阈值概率,较全面地比较分析不同概率水平下的属性约简效果,从而获取大学生心理危机的引致要素。通过问卷调查和对比分析计算,表明该方法获取的约简结果更具适用性,且具有更高的准确性和更低的分类误判率。
In order to recognize psychological crisis of college students effectively,according to the education statistics theory,a classification method based on dominance relation is used and a double limited dominance rough set approach and calculation method for early warning information system of psychological crisis of college students is established in this paper.According to the known properties values of each attribute of information system,the probability distribution is calculated.And the probability threshold is selected and compared with the obtained advantages of probability to realize the dominance relation judgment between each object.In addition,a comprehensive comparison and analysis of attribute reduction effect under different threshold probability is made to obtain the main factors of psychological crisis of college students.According to the questionnaire survey and comparative analysis and calculation,it indicates that the obtained simplified results is more applicable,and has higher accuracy and a lower error rate of classification.
