Abstract
Public hospitals are facing the dual pressure of coping with external medical market competition and performing public health duties. Due to the influence of various risk factors, public hospitals are facing increasing financial risks. How to effectively prevent and control financial risks and maintain the normal operation and sustainable development of the hospital is a very important topic that needs to be studied in the development of public hospitals. Because the traditional principal component analysis method only pays attention to the global structural features and ignores the local structural features, a financial risk early-warning model based on improved kernel principal component analysis in public hospitals is proposed to improve the ability of risk assessment. The core ideas of the method in this paper for financial risk forecasting are as follows: the nonlinear features of the financial data are firstly extracted under different conditions, and then the feature matrix and the optimal feature vector are calculated to construct the distance statistics so as to determines the threshold by kernel density estimation; finally the Fisher discriminant analysis is used for similarity measurement to identify the risk types. Through experiments on the financial data of a number of public hospitals and listed companies, the experimental results verify the feasibility and effectiveness of the method used in this paper for financial risk analysis. This further shows that this research has a certain display significance.
Highlights
Public hospitals are responsible for the important role of medical services and carry out medical research, cultivate medical talents, and respond to public emergencies, which are characterized by public welfare
Wagstaff et al analyzed the annual financial data of public hospital and developed a financial distress prediction model based on the support vector machine with radial basis function (RSVM) [14]. e empirical results show that RSVM is always better than other models in the performance of financial risk prediction
In order to prevent the correlation in the financial information from affecting the early warning, the accuracy has further processed the index data and a public-hospital financial crisis early-warning model constructed was based on principal component analysis and support vector machine methods. en the model is compared with the financial early-warning model based on logistic regression, BP neural network model, and single SVM in the empirical research
Summary
Public hospitals are responsible for the important role of medical services and carry out medical research, cultivate medical talents, and respond to public emergencies, which are characterized by public welfare. Victor et al analyzed the application of linear discriminant model, multilayer perceptron neural network, and wavelet network in the prediction of hospital financial risk and proposed an improved algorithm to select expansion and translation parameters to produce a wavelet network classifier with good simplicity features. Wagstaff et al analyzed the annual financial data of public hospital and developed a financial distress prediction model based on the support vector machine with radial basis function (RSVM) [14]. In order to prevent the correlation in the financial information from affecting the early warning, the accuracy has further processed the index data and a public-hospital financial crisis early-warning model constructed was based on principal component analysis and support vector machine methods.
