基于最小生成树的自闭症辅助诊断研究
Research on Auxiliary Diagnosis of Autism Based on Minimum Spanning Tree
【摘要】 目前在针对自闭症的分类研究中,构建阈值连接网络时,大多因不合理的阈值设置而影响最终分类结果。为了避免传统方法阈值选择的问题,文章对自闭症患者的最小生成树脑功能网络进行了研究,报告了正常被试与自闭症患者脑功能连接网络的差异,并设计了基于支持向量机的分类模型,实现对自闭症的分类工作。文中获得的分类准确率达到81.76%,相比于传统方法具有更高的敏感度和特异性。
【Abstract】 In current classification studies for autism,the final classification results are mostly affected by unreasonable threshold settings when constructing threshold connectivity networks.In order to avoid the problem of threshold selection by traditional methods,the minimum spanning tree brain function network of autistic patients is studied in this paper,and the differences between the brain function connectivity network of normal subjects and autistic patients are reported,and a support vector machine-based classification model is designed to realize the classification work for autism.The classification accuracy obtained in this paper reaches 81.76%,which has higher sensitivity and specificity compared to traditional methods.
