新手求助RBF神经网络数据预测问题-历史开奖数据.xlsx 本程序用前六个数据预测下一数据，前200组数据用于训练，用后80组数据进行预测，可预测结果为一个值，请大家指教： 源程序为： clc clear close all %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %每五个数据整合, x=xlsread; n=length m=5; sum=0; j=1; x1=zeros); for k=1:m:n for i=k: sum=sum x; end x1=sum; j=j 1; sum=0; end j t=1:; figure plot;%,'d-m' hold on; grid on title; %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %归一化处理 [x2,mint,maxt] = premnmx figure plot;%,'d-m' hold on; grid on title; %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %输入数据 for k=1:1:200 p_train=[x2 x2 x2 x2 x2 x2]; 5*6 t_train=x2; 5*1 end p_train=p_train'; %6*195 t_train=t_train'; %1*195 for z=1:1:81 p_test=[x2 x2 x2 x2 x2 x2]; t_test=x2; end p_test=p_test'; t_test=t_test'; %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %建立 RBF 网络 goal = 0.0001; % 训练误差的平方和 spread = 0.01; % 此值越大,需要的神经元就越少 MN = size; % 最大神经元数 DF = 1; % 显示间隔 net = newrb; data_out=sim p_mse=mse figure plot hold on plot title; %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %预测并作图 y=sim y_mse=mse figure plot; hold on; plot title; legend;
