Prediction algorithm based on the combination of chaos and neural network and it’s applications
【摘要】 探讨了混沌理论与前馈人工神经网络相结合进行非线性时间序列预测的基本原理,并对影响短波通信的两个参数:年太阳黑子数和天10cm辐射强度,在SVD滤波的基础上进行了预测。
【Abstract】 In this paper, the principles of nonlinear time series prediction based on the combination of Chaos theory and FeedForward Neural Network are set forth. A noisefiltering algorithm based on SVD (Singular Value Decomposition) is discussed too. Two parameters in shortwave communication: Sunspot number and 10cm flux are predicted based on the algorithm.
