＜正＞The application of neural network ensemble （NNE） to economic forecasting can heighten the generalization a-bility of learning systems through training multiple neural networks and combining their results. In this paper, principal component analysis （PCA） is developed to extract the principal component of the economic data under the prerequisite that the main information of original economic data is not lost, and the input nodes of forecasting model are effectively reduced. Based on Bagging, a NNE constituted by five BP neural networks is employed to forecast GDP of Jiangmen, Guangdong with favorable results obtained, which shows that NNE is superior to simplex neural network, and valid and feasible for economic forecasting.

Optimized Adaptive Fuzzy forecasting System with Application

引用

International Journal of Plant Engineering and Management 1998年第1期3卷 39-49页

作者： Yu Bin, Zhong Muliang, Zhang Hao, Mao Zongyuan, Zhou QijieDepartment of Automatic Control Engineering, South China University of TechnologyGuangzhou, 510641, P.R. China

In this paper, a fuzzy forecasting system is designed and implemented by which an original forecasting model can be obtained by data learning. The model parameters can then be adaptively optimized through gradient information of real-time data. Thus, the system is of extinguished adaptive feature and self-learning capability. Afterwards, experimental research efforts are put forward to carry out electric power load forecasting. Experimental results demonstrate the satisfactory performances of the intelligent forecasting system.

Measuring Nonlinear Dependence Between Time Series Based on Correlation Dimension

引用

Journal of Systems Science and Information 2009年第1期7卷 1-9页

In this paper, it is proved that the correlation dimension estimate of a nonlinear dynamical system with its multivariate observation series is the same as that with its univariate observation series. Based on this result, an inference method is presented, and the Nonlinear Dependence Coefficient is defined. This method is designed for testing nonlinear dependence between time series, and can be used in economic analysis and forecasting. Numerical results show the method is effective.
