| Abstract: | This paper is focused on using neural networks (NN) method to predict stock market- Firstly, the complexity of stock market and the existed prediction methods are summarized. Secondly, a noval method for optimizing the strucutre and weights of NN is proposed, which combines genetic algorithm (GA) and Davidon,s least squares algorithm. Finally, Shanghai stock indexes are fitted and predicted. The good results confirms the performance of the method. |
