Yanli Zhu, Xiaojuan Guo, Shun-Ping Wang, Ji-Fu Cheng · 2010
In this paper, a new prediction model, based on chaos theory and BP artificial neural network, is developed to predict the risk of credit card transactions. Embedding dimension of phase-space reconstruction is used to determine network structure, and overcomes the dependence on large amount of samples. Experiments shows that the method based on combination of chaos theory and neural network can improve the accuracy and speed of forecasting.
