本程序是对粮虫的3类回归的具体实现中的C和g的参数优化选择程序(This procedure is a Class 3 grain insects in the concrete realization of the return of C and g the parameter optimization selection process)

This Artificial Network model can be used to simulate a real transmission line in one or more of these respects.

ICA(独立成分分解),可实现采集信号中源信号的分离，便于提取特征量，实现模式识别。同时由于可以将源信号分离开来，可实现信号的降噪，去掉基波、三次谐波、五次谐波等(ICA (independent component decomposition) can realize the separation of the source signals in the acquisition signal, and facilitate the extraction of the feature quantity, and realize the pattern recognition. At the same time, because the source signal can be separated, it can realize the noise reduction of signal, remove the fundamental wave, the three harmonic, the five harmonic, etc.)
