One of the major challenges of providing reliable healthcare services is to diagnose and treat diseases in an accurate and timely manner. Recently, many researchers have successfully used artificial neural networks as a diagnostic assessment tool. In this study, the validation of such an assessment tool has been developed for treatment of the femoral peripheral arterial disease using a radial basis function neural network (RBFNN). A data set for training the RBFNN has been prepared by analyzing records of patients who had been treated by the thoracic and cardiovascular surgery clinic of a university hospital. The data set includes 186 patient records having 16 characteristic features associated with a binary treatment decision, namely, being a medical or a surgical one. K-means clustering algorithm has been used to determine the parameters of radial basis functions and the number of hidden nodes of the RBFNN is determined experimentally. For performance evaluation, the proposed RBFNN was compared to three different multilayer perceptron models having Pareto optimal hidden layer combinations using various performance indicators. Results of comparison indicate that the RBFNN can be used as an effective assessment tool for femoral peripheral arterial disease treatment.
提供可靠医疗服务的主要挑战之一是准确及时地诊断和治疗疾病。最近,许多研究人员成功地将人工神经网络用作诊断评估工具。在这项研究中,使用径向基函数神经网络 (RBFNN) 为治疗股外周动脉疾病开发了这种评估工具的验证。通过分析在一所大学医院的胸心血管外科诊所接受治疗的患者记录,准备了用于训练 RBFNN 的数据集。该数据集包括 186 个患者记录,具有 16 个与二元治疗决策(即医疗或手术)相关的特征。K-均值聚类算法用于确定径向基函数的参数,并且 RBFNN 的隐藏节点数通过实验确定。为了进行性能评估,使用各种性能指标将所提出的 RBFNN 与具有帕累托最优隐藏层组合的三个不同的多层感知器模型进行了比较。比较结果表明,RBFNN 可作为股外周动脉疾病治疗的有效评估工具。
