采用BP神经网络实现图像压缩，方法简单易行。(Image compression is realized by using the BP neural network，Method is simple。)

As significant work was done in machine learning in past two decades, we have limited to recent articles in machine learning. A brief review of machine learning and its application can found in [Duttion and Conroy,1996). The most common supervised learning method and major implementation to various machine learning applications is artificial neural network as ANNs.

this programs transforms a matrix to a vector which is used after applying a hamming window with 50 overlap and totally useful for speech enhancement

这是一个使用EMD分解出IMF的例子，一个试验信号由一个tone信号，一个chirp信号，叠加得到，目的是使用EMD将这两个信号分离，得到的预期结果应该是chirp信号在高阶，tone信号在低阶，（原因是chirp信号在各个局部的频率都比tone信号高）。(This is an example of using EMD to decompose the IMF. A test signal consists of a tone signal and a chirp signal. The purpose is to separate the two signals using EMD. The expected result should be that the chirp signal is at a higher order, the tone The signal is in the low order, (because the chirp signal is higher in all local frequencies than the tone signal).)
