SVM方法的基本思想是：定义最优线性超平面，并把寻找最优线性超平面的算法归结为求解一个凸规划问题。进而基于Mercer核展开定理，通过非线性映射φ，把样本空间映射到一个高维乃至于无穷维的特征空间（Hilbert空间），使在特征空间中可以应用线性学习机的方法解决样本空间中的高度非线性分类和回归等问题。svm 程序，即支持向量机的代码。(The basic idea of SVM method are: the definition of the optimal linear hyperplane, and the search algorithm for optimal linear hyperplane by solving a convex programming problem. Then based on Mercer nuclear expansion theorem, through a nonlinear mapping φ, the sample space is mapped to a high-dimensional and even infinite dimensional feature space (Hilbert space), so that in the feature space can be applied to solve the linear learning machine method, the sample space The highly nonlinear classification and regression problems. svm procedures that support vector machine code.)

说明：  这是二战时期著名的，独领一时风骚的密码机Enigma的源代码，它真实的再现了Enigma的工作原理和真实原貌，希望有兴趣的朋友共同参详(This is the famous World War II, was the sole lead of 1:00 coquettish Enigma cipher machine source code, it is a true reproduction of the working principle of the Enigma and true original, want to have a friend interested in the common parameters are set)

说明：  这是一个matlab程序用于构建人工神经网络模型，可以随意设置层数和单元个数！(This is a matlab program for building artificial neural network model can arbitrarily set the number of layers and units!)

Particle Sworm Optimization algorithms

The SMOTE function takes the feature vectors with dimension(r,n) and the target class with dimension(r,1) as the input. And returns final_features vectors with dimension(r ,n) and the target class with dimension(r ,1) as the output.
