在共梯度法中 只有当初值的选取靠近最优解时 迭代才会收敛 当远离时发散 且 当精度控制为0.1时可以实现 但设为0.01时就实现不了(numeberica method)

运用MATLAB制作高通、低通等各种滤波器，实现变声系统。(Making use of MATLAB to create high pass, low pass and other filters,to achieve the goal of changing the sound . )

这是基于CSR算法在非局部环境的扩充表示，并应用在去噪上(This algorithm is based on CSR in the expansion of non-representation of the local environment, and apply the de-noising)

说明：  蚁群算法功能介绍及软件算法实现，例题数据及代码运行。(ant colony algorithm)

有向无环图支持向量(DAG-SVMS)多类分类方法,是一种新的多类分类方法。该方法采用了最小超球体类包含作为层次分类依据。试验结果表明,采用该方法进行多类分类,跟已有的分类方法相比有更高的分类精度。 (Directed acyclic graph support vector (DAG-SVMS) multi-category classification methods, is a new multi-category classification methods. The method uses the smallest category of super-sphere that contains the level of classification as a basis. The experimental results show that using the method of multiclass classification with the classification method has been compared to a higher classification accuracy.)
