Design and implementation of financial prewarning model based on data-mining
基于数据挖掘的财务预警模型设计与实现

Since the ID3 algorism has obvious advantage on attribute screening, the algorism so as to get a simplified financial index system was modified in this paper. Then, as artificial neural network is better in constructing financial prewarning model than other linear and regression models, a new financial prewarning model based on B-P model was constructed. At last, the ability to prewarn the financial risk between the new financial prewarning model and the classic Z-score model were compared in terms of first error ratio and second error ratio. The prewarning ability of the new model has been proved.
