Minimum-Risk-Bayes-classifier
这是模式识别中最小风险Bayes分类器的设计方案。在参考例程的情况下，自行完善了在一定先验概率的条件下，男、女错误率和总错误率的统计，放入各个数组当中。
全部程序由主函数、最大似然估计求取概率密度子函数、最小错误率贝叶斯分类器决策子函数三块组成。
调用最大似然估计求取概率密度子函数时，第一步获取样本数据，存储为矩阵；第二步对矩阵的每一行求和，并除以样本总数N，得到平均值向量；第三步是应用公式（3-43）采用矩阵运算和循环控制语句，求得协方差矩阵；第四步通过协方差矩阵求得方差和相关系数，从而得到概率密度函数。
调用最小风险贝叶斯分类器决策子函数时，根据先验概率，再根据自行给出的5*5的决策表，通过比较概率大小判断一个体重身高二维向量代表的人是男是女，放入决策数组中。
主函数第一步打开“MAIL.TXT”和“FEMALE.TXT”文件，并调用最大似然估计求取概率密度子函数，对分类器进行训练。第二步打开“test2.txt”，调用最小风险贝叶斯分类器决策子函数，然后再将数组中逐一与已知性别的数据比较，就可以得到在一定先验概率条件下，决策表中不同决策的错误率的统计。
(This is a pattern recognition classifier minimum risk Bayes design .In reference to the case of routine , self- improvement in a certain a priori probability conditions, male , female and total error rate error rate statistics , into which each array .
All programs from the main function , maximum likelihood estimation subroutine strike probability density , the minimum error rate Bayesian classifier composed of decision-making three subfunctions .
Strike called maximum likelihood estimate probability density subroutine , the first step to obtain the sample data , stored as a matrix the second step of the matrix, each row sum , and divided by the total number of samples N, be the average vector The third step is the application of the formula ( 3-43 ) using matrix and loop control statements , obtain the covariance matrix fourth step through the variance-covariance matrix and correlation coefficient obtained , resulting in the probability density function .

可以大批量地处理数据的导入，并将无关行列删除，再对数据中的字符串、数字格式统一，与拼接，并与另一个xls文档中的数据进行比较，是一个不错的代码。(Can import large quantities of process data, and independent of the ranks to delete the data string, the unity of the digital format, with the stitching, and compare the data with another xls document, which is a good code.)

本程序采用遗传算法接力进化,子函数和主函数不要放在一起，子函数另外作为一个M文件，运行主函数。多次运行主函数，直到达到误差满意的效果。(This procedure using genetic algorithm (ga) relay evolution, function and main function don t together, and function of the file as a M, run the main function. Run several times the main function, the error until you reach satisfactory results.

对数据进行EMD分析时，如果数据不是纯的白噪声,则分析过程中一些尺度将会丢失,出现模态混叠现象。EEMD通过附加均匀分布
在整个时频空间的白噪声，可有效抑制这种现象的发生。(EEMD is insufficient for the EMD method, we propose a noise-assisted data analysis methods. EEMD decomposition principle is: when the additional white noise uniformly distributed throughout the time-frequency space, the time-frequency space is carved up by the filter component of the composition at different scales.-)
