对具有随机噪声的二阶系统的模型辨识及其被辨识系统的辨识结果(Second order with random noise on the system model and its identification system identification results are)

采用模糊C均值对数据集data聚为cluster_n类(Fuzzy C mean data on the data sets together to cluster_n class)

function g=distance_classify(A,b) 距离判别法程序。 输入已分类样本A（元胞数组），输入待分类样本b 输出待分类样本b的类别g 注：一般还应计算回代误差yita 输入已知分类样本的总类别数n 每类作为元胞数组的一列(function g = distance_classify (A, b) from the Criterion procedures. Input samples have been classified A (cell array), the importation of samples for classification b output samples for classification g categories b Note: the calculation should also be back on behalf of the general error input yita of the total known types of classification of the number of samples n each Cellular-type array as a)

在MATLAB环境下产生白噪声程序，三个性质可以设定，能够正常使用(In the MATLAB environment to produce white noise process, the three properties can be set to normal use)

基于EKF的参数估计算法理论，这是个英文文献，主要介绍了用EKF方法去识别结构的参数。(The parameter estimation algorithm based on EKF theory, this is English literature, introduces the parameters EKF method to identify structures.)

Matlab工具包补充算发，包括各种噪声代码及滤波倒向Smoother代码等(Matlab toolkit added fat count, including all kinds of noise code and filter code, such as backward Smoother)

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].
