关于统计学习正则化的阈值算法，对现有的最小二乘问题进行扩展。(On statistical learning is the threshold algorithm is based on the expansion of the existing least squares problems.)

利用夹角余弦距离进行样本数据分类。实现步骤主要分为以下两部分：a、待测样品X与训练集里每个样品Xi的距离采用夹角余弦距离公式计算。b、循环计算待测样品和训练集中各已知样品之间的距离，找出距离待测样品最近的已知样品，该已知样品的类别就是待测样品的类别。(Using the sample data classification Angle cosine distance.Implementation steps are divided into the following two parts: a, sample under test with each of the samples in the training set X Xi distance using the included Angle cosine distance formula.B, loop calculation under test samples and the distance between the known samples training focus, find out the known closest to the sample under test samples, the samples of known category is the category of the sample under test.)

说明：  采用卡尔曼滤波器的PID控制。控制干扰信号与测量噪声信号幅值均为0.002的白噪声信号。采用滤波器是控制效果明显改善。 (Discrete Kalman filter for PID control)

说明：  基于Pca的人脸自动识别源码 采用orl人脸库 最后出现识别数目(Automatically identify the source of Pca-based face orl face database last identification number)

具有微分先行的PID控制方法，可以设置M参数查看控制效果（M=1为微分先行的控制效果）。(PID control with derivative first method, you can see the control effect parameters set M (M = 1 for the first derivative of the control effect).)
