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 實現了經驗模態分解方法在非線性和非穩態信號瞬時特征提取中的應用;同時利用實驗數據證明了經驗模態分解方法與多層反饋神經網絡fp算法相結合,來完成股票數據預測中的相似模式匹配的可行性。
