Realizing the application of the empirical mode decomposition in the instantaneous characters extraction of the non - linear and non - stationary signals . in the meanwhile , it has proved that it is feasible to realize the similar pattern matching of the stocks " forecasting , if the empirical mode decomposition and the forward propagation learning algorithm of multi layered neural networks with feed back connections are related 实现了经验模态分解方法在非线性和非稳态信号瞬时特征提取中的应用;同时利用实验数据证明了经验模态分解方法与多层反馈神经网络fp算法相结合,来完成股票数据预测中的相似模式匹配的可行性。
