pca 轴承故障诊断程序
最小均方算法，借助于最速下降算法发展起来的，通过维纳滤波所求维纳解，已知输入信号与期望信号的先验统计信息，以及再对输入信号的自相关矩阵进行求逆运算的情况下才能得以确定，计算复杂程度低，收敛性好(Least mean square algorithm, with the help of the steepest descent algorithm is developed, using wiener filtering for wiener solution of known prior statistical information input signal and the desired signal, and then the input signal under the condition of inversion of the autocorrelation matrix can be determined, low computing complexity and good convergence)

matlab表情识别
Matlab表情识别，特征脸[1 ]作为面部表情分类的方法。首先，利用训练图像创建低维人脸空间（pca）。这是通过训练图像集主成分分析（PCA）及图片主成分分析（即具有较大特征值的特征向量）获得的。
结果，所有的测试图像以所选择的主成分表示，计算投影图像与所有投影列车图像的欧几里得距离，选择最小值以找出与试验图像最相似的训练图像。(The feature face [1] is used as a facial expression classification method. Firstly, a low-dimensional face space (pca) is created using training images. This is obtained by training principal component analysis (PCA) of image set and principal component analysis of image (i.e. eigenvectors with larger eigenvalues).
As a result, all the test images are represented by the selected principal components, the Euclidean distance between the projected image and all the projected train images is calculated, and the minimum value is selected to find the training image most similar to the test image.)
