| Abstract: | In order to improve the precision of stock price forecasting,in this paper,a stock price forecasting model based on improved support vector machine was proposed.Particle swarm optimization algorithm which has global optimization ability was used to optimize the parameters of support vector machine to improve the precision of prediction of stock price.The performance of the model was tested by stock price data,and the result showed that the improved support vector machine could describe the stock price change trend.and It was an effective,high precision stock price forecasting model. |
