myshift

本压缩包中包括了几个常用的经典的数据挖掘算法，有k_means，CART，fuzzy_k_means，id3，SVM，很有实用性(The compressed package includes several commonly used classical data mining algorithms, there are k_means, CART, fuzzy_k_means, id3, SVM, is very practical)

1.duishuzhengtai：产生对数正态分布 2.gaussian：产生数据量为n的两个相互独立高斯分布y1、y2 3.junyun：自定义 0-1的均匀分布，n代表数据量，一般要大于1024（蒙特卡罗） 4.ruili：瑞利分布,m是瑞利分布的参数,n代表数据量,n一般要大于1024 5.kaifeng：产生开丰分布，其中m代表开丰分布的自由度，n表示产生的点数量 6.tfenbu：本函数产生自由度为m，数据量为n的t分布。 7.weibuer：a=1时,是指数分布；a=2时,是瑞利分布(1.duishuzhengtai: generating lognormal 2.gaussian: generating a data quantity n of two mutually independent Gaussian distribution Y1, Y2 3.junyun: custom uniform distribution of 0-1, n represents a data amount, generally large in 1024 (Monte Carlo) 4.ruili: Rayleigh distribution, m is a parameter of the Rayleigh distribution, n representative of the amount of data, n is generally greater than 1024 5.kaifeng: generating open abundance distribution, wherein m represents an open-abundance distribution freedom of degrees of freedom, n is the number of points generated 6.tfenbu: This function generates m, the amount of data for n t distribution. 7.weibuer: a = 1, the exponential distribution a = 2, is a Rayleigh distribution)

QPSK是通信信道中一种很好的调制方式，对于其性能参数进行了仿真，信道以及噪声选择可以根据代码自由改动。对学习无线编码很有用处。(QPSK is a good communication channel modulation, the performance parameters for the simulation, channel and noise free choice can be altered according to the code. Learning wireless encoding useful.)

本DTW的语音识别算法是日本学者sakoe提出的，这种方法比itkura的要好，但本算法没使用到加权，方法简单了，以后再图改进(The DTW recognition algorithm is proposed by Japanese scholars sakoe, this method is better than itkura, but did not use this method to the weighted method is simple, and later plans to improve)
