Due to the growing number of disabilities in elderly, Attention to this period of life is essential to be considered. Few studies focused on the physical, mental, disabilities, and disorders affecting the quality of life in elderly people. SA is related to various factors influencing the elderly's life. So, the objective of the current study is to build an intelligent system for SA prediction through ANN algorithms to investigate better all factors affecting the elderly life and promote them.
This study was performed on 1156 SA and non-SA cases. We applied statistical feature reduction method to obtain the best factors predicting the SA. Two models of ANNs with 5, 10, 15, and 20 neurons in hidden layers were used for model construction. Finally, the best ANN configuration was obtained for predicting the SA using sensitivity, specificity, accuracy, and cross-entropy loss function.
The study showed that 25 factors correlated with SA at the statistical level of < 0.05. Assessing all ANN structures resulted in FF-BP algorithm having the configuration of 25-15-1 with accuracy-train of 0.92, accuracy-test of 0.86, and accuracy-validation of 0.87 gaining the best performance over other ANN algorithms.
Developing the CDSS for predicting SA has crucial role to effectively inform geriatrics and health care policymakers decision making.
由于老年人残疾数量不断增加,关注这一生命阶段至关重要。很少有研究关注影响老年人生活质量的身体、心理、残疾和疾病。衰弱与影响老年人生活的各种因素有关。因此,本研究的目的是通过人工神经网络算法构建一个用于衰弱预测的智能系统,以更好地研究影响老年人生活的所有因素并促进这些因素。
本研究对1156例衰弱和非衰弱病例进行。我们应用统计特征约简方法以获得预测衰弱的最佳因素。使用隐藏层具有5、10、15和20个神经元的两种人工神经网络模型进行模型构建。最后,使用灵敏度、特异性、准确性和交叉熵损失函数获得用于预测衰弱的最佳人工神经网络配置。
研究表明,在统计学水平<0.05时,有25个因素与衰弱相关。评估所有人工神经网络结构后发现,前馈反向传播(FF-BP)算法的配置为25-15-1,训练准确率为0.92,测试准确率为0.86,验证准确率为0.87,在其他人工神经网络算法中表现最佳。
开发用于预测衰弱的临床决策支持系统对于有效地为老年医学和医疗保健政策制定者的决策提供信息具有至关重要的作用。
