说明：  bp神经网络的源程序，很实用，很不错的！(bp neural network source code, very practical, very good!)

这是用matlab写的dct代码用于图像的信息的隐藏和提取。。部分老师写的哦。(This is used to write the DCT matlab code for the image and extract the hidden information. . Oh part of the Writing Teacher.)

对呼吸信号进行检测的MATLAB程序，输入采集到的呼吸电信号，输出呼吸信号的峰值。(The respiratory signal detection MATLAB program, enter the collection to the respiratory signal, the output signal peak breath.)

Koch曲线是通过图形迭代的方式产生的，其迭代规则是：对一条线段，首先将它分成三等份，然后将中间的一份替换成以此为底边的等边三角形的另外两条边。无限次迭代下去，最终形成的曲线就是Koch曲线。(Koch curve is generated by way of graphical iteration, and its iteration rule is: for a segment, it is divided into three equal parts first, and then replace the middle of a bottom side of this equilateral triangle to the other two edges. Infinite iterations continue, the final form of the curve is the Koch curve.)

高斯过程是一种非参数化的学习方法，它可以很自然的用于regression，也可以用于classification。本程序用高斯过程实现分类！(Gaussian process is a non- parametric method of learning, it is very natural for regression. can also be used for classification. The procedures used to achieve classification Gaussian process!)

卡尔曼滤波器预测，以及一周卡尔曼滤波器预测(Kalman filter forecast, and a week Kalman filter forecast)

matlab粗糙集算法，主要使用于神经网络和支持向量机等算法的预处理，可以有效地筛选数据(matlab rough set algorithm, mainly used in the pre-processing of the neural network and support vector machine algorithm can effectively filter the data)

随机网络的仿真计算，用Matlab来实现的源代码。(Stochastic network simulation, using Matlab to implement the source code.)

Bubble Point Calculation

说明：  人脸检测，能用于单人和多人脸图的检测识别，效果不错。(Face detection,It can be used in the detection and recognition of single face and multi face images with good effect.)
