摘要
目的采用SARIMA、BP神经网络、RBF神经网络及小波神经网络模型对贵州省某专科医院的精神类疾病患者数进行拟合及预测,并比较各类预测模型的预测效果。方法将贵州省某专科医院2016年1月1日~12月31日HIS系统中精神类疾病的数据作为训练集,建立SARIMA(1,1,1)×(1,1,1)3模型、BP神经网络、RBF神经网络、小波神经网络模型。分别对2017年1月1日~16日精神类疾病患者数进行预测,将2017年1月1日~16日数据作为验证集。分别用3类误差分析指标衡量模型的拟合效果,并比较模型预测的准确性。结果RBF神经网络模型对该医院精神类疾病患者数的拟合效果优于BP神经网络和小波神经网络模型,平均绝对误差为(1.84×10^-7)%,平均相对误差为4.92×10-6,均方根误差为4.74×10^-6。3类预测误差平均值分别为23.70%、3.633、93.72。结论4种模型均能用于医院精神类疾病患者数的预测,但就预测效果而言,小波神经网络模型的各项误差指标均低于其他3种预测模型,小波神经网络模型可作为预防和医院管理的理论依据。
Objective To fit and predict the number of mental illness patients in a specialized hospital in Guizhou Province by SARIMA, BP neural network, RBF neural network and wavelet neural network model, and compare the prediction effects of these types of prediction models. Methods The data of mental illness in the HIS system from January 1 to December 31, 2016 in a specialized hospital in Guizhou Province was used as a training set to establish the SARIMA (1,1,1)×(1,1,1)3 model. BP neural network, RBF neural network, wavelet neural network model. The number of patients with mental illness was predicted from January 1st to 16th, 2017, and the data from January 1st to 16th, 2017 was used as the verification set. The three types of error analysis indicators were used to measure the fitting effect of the model, and the accuracy of the model prediction was compared. Results The RBF neural network model was better than BP neural network and wavelet neural network model in fitting the number of patients with psychiatric diseases. The average absolute error was (1.84×10^-7)%, and the average relative error was 4.92×10-6. The square root error is 4.74×10^-6. The average values of the three types of prediction errors are 23.70%, 3.633, and 93.72, respectively. Conclusion The four models can be used to predict the number of patients with mental illness in hospitals. However, in terms of prediction results, the error indicators of wavelet neural network model are lower than the other three prediction models. The wavelet neural network model can be used as prevention and The theoretical basis of hospital management.
