Implementacao da rede MLP canonica (backpropagation com gradiente descendente)

进行C均值聚类，样本是男女身高体重数据，在程序中增加了很多注释说明部分，适合广大初学者。(Perform C-means clustering, the sample was male and female height and weight data, adds a lot of explanatory notes section in the program, for the majority of beginners.)

本程序可以产生LFM信号，经过实验验证，程序正确，可以执行，改变参数即可得到你想要的图形(produce a LFM signal)

GMDH_main为GMDH主函数； variable_Combin为输入层初始变量选为x1,x1^2,x1*x2,x2^2,x2时的输入变量矩阵值 variable_select计算X_train训练输入数据,Y_train训练输出数据,X_test测试输入数据,Y_test测试输出数据 Combin为求变量的两两组合 Sym_Combin为求符号变量的两两组合 PE_AIC求每层各神经元的参数估计W，及训练数据在参数估计后估计的输出out_train，测试数据在参数估计后的估计输出out_test，还有与实际比较的误差平方和PESS， 以及准则值AIC sym_representation求最终的输入输出符号表达式 Criterion_value求准则值 (GMDH_main main function for the GMDH variable_Combin initial variables chosen for the input layer, x1, x1 ^ 2, x1* x2, x2 ^ 2, x2 the value of the input variable matrix calculation X_train variable_select training input data, Y_train training output data, X_test test input data, Y_test for the sake of the test output data Combin pairwise combination of variables for the sake of symbolic variables Sym_Combin pairwise combinations PE_AIC neurons find each parameter estimation of the W, and after the training data is estimated in the estimation of output out_train, test data After the parameter estimates of the output estimated out_test, also compared with the actual sum of squared errors PESS, as well as the final criterion value AIC sym_representation seek the input and output values ​ ​ of symbolic expressions Criterion_value find criteria)

程序主要是求一段音频数据的基音频率 jiyinzhouqi.m --------求基音周期 find_maxn.m --------求自相关函数的最大值 test2.wav --------程序中用到的示例wav数据文件(The program is mainly the fundamental frequency for an audio data Jiyinzhouqi.m- for pitch period Find_maxn.m- the maximum value of autocorrelation function Test2.wav: the procedures used in the example of wav data file)

Delta机器人工作空间，用MATLAB做的，3D模型，可以参考了看看，国外专家做的(Delta robot workspace, MATLAB do, 3D models, you can refer to the look, foreign experts do)
