Abstract

It is very important to enhance the accuracy of financial crisis prediction (FCP). Because the traditional probabilistic neural network (PNN) has some deficiencies, such as the difficult estimation of parameters and the high computational complexity, this paper proposes a new combination model, which combines back-propagation (BP) with PNN on the basis of adaptive boosting algorithm, to predict financial crisis. The BP algorithm is introduced to modify weights and smoothing parameters of PNN. In process of constructing BP-PNN models, the training set is divided into study and training samples to save the computational time. And the trained models are regarded as weak classifiers. Then these weak classifiers are integrated to constitute a stronger classifier by adaboost algorithm. To verify the superiority of the new model in terms of FCP, this article uses financial data of Chinese listed companies from Shenzhen and Shanghai Stock Exchange, and compares with adaboost BP, PNN and support vector machine models. The result shows that the new model has the highest prediction accuracy. Therefore, the new combination model is an excellent method to predict financial crisis.
