摘要
为了提高传统Z-Score财务预警模型的预警能力,本文将改进FOA算法的良好寻优能力和Z-Score财务预警模型相结合,提出了一种改进FOA算法的上市公司Z-Score财务预警模型.采用改进FOA算法来优化ZScore模型的参数,降低预测值和目标值之间的均方根误差(RMSE).经对选取上市公司财务数据的预测值和目标值对比,且检验其准确率.实验结果:传统的Z-Score模型、基本FOA算法优化Z-Score模型和改进FOA算法优化Z-Score模型的预测准确率分别为65%、70%和80%.实验表明改进的算法较大提升了Z-Score财务预警模型的预测能力,也表明了该算法的有效性.
In order to improve the prediction ability of the traditional Z-Score financial prediction model, this paper proposes a financial prediction model of Z-Score for listed companies based on improved Fruit fly Optimization Algorithm(FOA) by combining the good searching ability of improved FOA algorithm and the Z-Score financial prediction model. The Root Mean Square Error(RMSE) between the predicted value and target value is reduced by improved FOA algorithm being applied to optimize the parameters of Z-Score model. We compare the predicted value and target value of the financial data of listed companies to test the accuracy of financial prediction. The experimental results are as follows: accuracies of the traditional Z-Score financial prediction model, FOA algorithm optimized Z-Score model, and improved FOA algorithm optimized Z-Score model are 65%, 70%, and 80%, respectively. Experiments show that the improved algorithm significantly improves the predictive ability of Z-Score financial prediction model, it is also illustrated the validity of the algorithm.
