matlab做的，关于滚动轴承振动信号故障诊断很重要的数据库，做机器学习的朋友可以看看啊！(Matlab do, on the rolling bearing vibration signal fault diagnosis is very important , machine learning friends can see ah!)

说明：  测试nsga2的优化性能,包含zdt系列、sch系列，支持三个目标下的约束求解(NSGA-II TEST,including zdt series,sch series and is okay for a 3-dimensional minimization problem.)

用MATLAB画一个弯曲的圆柱 思想：把圆柱按轴线分若干段，在每个断面画圆，圆的法线就轴线的切向方向。柱面画若干平行于轴线的线条，其中用到平行单位矢量点积等于1，不平行的结果是[-1，1）。 (MATLAB painting with a cylindrical curved thinking: the cylinder axis by a number of sub-paragraph in each section drawcircle, round on the normal axis of the tangential direction. Painted a number of cylindrical axis parallel to the lines, which use a parallel unit vector point plot equal to 1, the result is not parallel to [-1,1).)

随机信号分析理论如何在实践中应用；随机信号的检测及分析方法；强噪声背景下微弱信号的提取又是信号检测的难点，其目的就是消除噪声，将有用的信号从强噪声背景中提取出来(How random signal analysis theory applied in practice random signal detection and analysis methods strong noise background of weak signal extraction and signal detection is difficult, its purpose is to eliminate the noise, the useful signal from strong background noise extracted)

Finally, probability analysis, based on the chosen database, is performed and judgment whether the person is recognized is pronounced. Two different modeling techniques can be suggested for purposes of person identification or verification. The approach based on Hidden Markov Speaker Models (HMMs) with the mixtures of Gaussian distribution is text-dependent one. For this technology a speaker is described by a set of HMMs, constructing the set of speech groups spoken by that person. The speech groups may be phonemes or words [7]. The text-independent technology is rested upon Gaussian Mixture Speaker Models. For this technology each speaker is defined by only one model describing all utterances of that person. Identification in the range of both approaches is executed by evaluation of maximum a posteriori probability [7].
