中文说明： 本程序的性能已经超过其他算法，小波包分析提取振动信号中的特征频率，最大似然（ML）准则和最大后验概率（MAP）准则，是机器学习的例程，esprit算法对有干扰的信号频率进行估计,Relief计算分类权重。
English Description：
The program performance has more than other algorithm, wavelet packet analysis and extraction of characteristic frequency in the vibration signal, the maximum likelihood (ML) criterion and the maximum a posteriori (map) criterion, is machine learning routines, the ESPRIT algorithm is used to estimate the interference signal frequency and relief meter calculate weights in classification.
