（压缩包里一共有5个代码） pca+lda+粗糙集+模糊神经网络 saveORLimage.m将ORL人脸库分为测试集ptest和训练集pstudy存为imagedata.mat 1.savelda.m将人脸库先进行pca降维，再用lda进行特征提取，得到新的测试集ldatest和训练集ldastudy存为imageldadata.mat 2.对ldastudy进行离散化(discretimage.m)，得到离散化矩阵disdata,存入到imagedisdata.mat 3.将disdata组成决策表(savers.m)，通过对disdata的条件属性进行约简，得到其一个约简，组成新的测试集rstest和训练集rsstudy存为imagersdata.mat 4.对rsstudy进行模糊神经网络训练(savecul.m)，对模糊神经网络的参数进行调整学习将其存入culdata.mat 5.用runfnn.m对rstest进行测试得到其识别率 savem.m和cm.m是用最小距离分类器对训练集和测试集进行分类.(pca+ lda+ Rough Set+ fuzzy neural network saveORLimage.m will ORL face database is divided into test set and training set ptest for pstudy keep imagedata.mat Treasury will face 1.savelda.m first dimensionality reduction pca, lda used feature extraction, a new test set and training set ldatest for ldastudy keep imageldadata.mat 2.

说明：  差分编码子程序,在调治之前对信号进行差分编码(differential coding subroutine, prior to the modulating signal differential coding)

数据拟合程序，可实现数据的三阶自定义函数的最小二乘拟合(Data fitting procedure, enabling third-order data, least squares fitting custom functions)

这是图像去噪的matlab程序源代码,可以对图像噪声有效地去除.(This is the image denoising matlab program source code, you can effectively remove the image noise.)

matlab交叉验证cross Validation，把样本集分为训练集和测试集，防止网络出现过拟合，提高网络的泛化能力和预测精度(cross Validation for matlab，to estimate the test accuracy,training accuray and validation accuracy of a neural network)

Matlab codes for Face and Eye detection.

基于matlab GUI的pid整定分析，可以根据输入的函数实时输出波形，还可以对pid系数进行设定(Setting the pid matlab GUI-based analysis, real-time output function according to the input waveform can also be set to pid coefficient)
