语音增强中的小波去噪，主要是抑制细节信号中，进行清音浊音判别，进行阈值选取(wavlet)

模糊C均值聚类（FCM），即众所周知的模糊ISODATA，是用隶属度确定每个数据点属于某个聚类的程度的一种聚类算法。(Fuzzy C means clustering (FCM), known as fuzzy ISODATA, is used to determine membership of each data point belongs to a cluster of a clustering algorithm level.)

R/S分析法中如何求解重标极差，得到后使用最小二乘估计就可以得到，Hurst指数(R/S analysis method on how to solve the rescaled range, obtained after the least-squares estimation can be used, Hurst index)

高阶谱双谱程序，非常实用的双谱例程供你参考(Order spectrum bispectral procedures, very practical double spectral routines for your reference)

网上能下载的本书的中文版均缺少89和97两页，又此书已绝版，本人只好从英文完整版中摘录缺少的内容，分别补全了这两页的内容。注：英文完整版也已经作为PDF的附件加了进去。 我也上传到了IASK，不能下载的朋友可以去搜索“(中文版)支持向量机导论.rar”(Internet can download the Chinese version of the book were missing two 89 and 97, and the book is out of print, I had to excerpts missing content from the English full version, respectively, to complement the content of the two pages. Note: The full version of English has also been added as an attachment inside a PDF. I also uploaded to the IASK, can not download friends can go search for "(Chinese version) Introduction to Support Vector Machines. Rar")

说明：  （拟合） 用给定的多项式，y=x3-6x2+5x-3，产生一组数据(xi,yi，i=1,2,…,n),再在yi上添加随机干扰(可用rand产生(0,1)均匀分布随机数,或用rands产生N(0,1)分布随机数)，然后用xi和添加了随机干扰的yi作的3次多项式拟合，与原系数比较。 如果作2或4次多项式拟合，结果如何？ ((Fitting) with a given polynomial, y = x3-6x2+5 x-3, generated a set of data (xi, yi, i = 1,2, ..., n), then add a random disturbance yi ( can be generated rand (0,1) uniformly distributed random number, or rands generated N (0,1) distribution of random numbers), and then added with xi and yi for random interference of the 3 times polynomial fitting, and the original coefficient. If 2 or 4 times for polynomial fitting, the result?)

说明：  无约束优化问题一维搜索的常用方法：黄金分割法（golden_section.m）、加步搜索法（plus_step_search.m）、牛顿法（newton.m）、抛物线法（parabola.m）(Unconstrained optimization problem of one-dimensional search of the commonly used methods: Golden Section (golden_section.m), plus step-by-step search method (plus_step_search.m), Newton (newton.m), parabola method (parabola.m))

传统的pid控制算法,系统函数是无时滞的,采用增量式的pid控制算法.(traditional pid control algorithm, the system function is without delay, using the incremental pid control algorithm.)
