用于数据处理时的孤立点分析，剔除孤立点，从而使历史数据更加准确(Outlier analysis for data processing, excluding the outlier, so that more accurate historical data)

说明：  噪声调频信号的产生：1、产生高斯噪声电压 2。用6极点椭圆滤波器形成噪声带宽 3。将滤波器输出送到一压控震荡器，输出即为调频噪声干扰信号(Noise FM signal generation: 1, resulting in Gaussian noise voltages 2. 6-pole elliptic filter noise bandwidth of the formation of 3. The filter output to a voltage controlled oscillator output signal noise shall be FM)

聚类算法，不是分类算法。分类算法是给一个数据，然后判断这个数据属于已分好的类中的具体哪一类。聚类算法是给一大堆原始数据，然后通过算法将其中具有相似特征的数据聚为一类。这里的k-means聚类，是事先给出原始数据所含的类数，然后将含有相似特征的数据聚为一个类中。所有资料中还是Andrew Ng介绍的明白。首先给出原始数据{x1,x2,...,xn}，这些数据没有被标记的。初始化k个随机数据u1,u2,...,uk。这些xn和uk都是向量。根据下面两个公式迭代就能求出最终所有的u,这些u就是最终所有类的中心位置。(Clustering algorithm, not a classification algorithm. Classification algorithm is to give a figure, and then determine the data belonging to a specific class of good which category. Clustering algorithm is to give a lot of raw data, and then through the algorithm which has similar characteristics data together as a class. Here k-means clustering, is given in advance the number of classes contained in the raw data, then the data contain similar characteristics together as a class. All information presented in or Andrew Ng understand. Firstly, raw data {x1, x2, ..., xn}, the data is not labeled. K random initialization data u1, u2, ..., uk. These are the vectors xn and uk. According to the following two formulas can be obtained final iteration all u, u is the ultimate all these classes the center position.)

AOK自适应时频分布算法， 是基于自适应最优核的时频分析软件，该软件包括自适应时频分析的计算内核及Matlab 交互脚本。计算内核是基于C 编译的，并针对Intel P4、AMD 作了不同优化；(based on Adaptive optimal kernel time-frequency analysis software based on Adaptive optimal kernel time-frequency analysis software)
