最小二乘支持向量机(LSSVM)

LSSVM - Regression

(注意：若将LSSVM工具箱纳入toolbox目录，可能导致BPNN网络构建失败)

应对措施：移除LSSVM的路径信息

load regressionData.mat;
output = output';

% 数据集划分
[value,index] = sort(rand(1,2000));
x_train = input(index(1:1800),:);
x_test = input(index(1801:2000),:);
y_train = output(index(1:1800),:);
y_test = output(index(1801:2000),:);

% 参数设定
gamma = 10;
sig2 = 0.2;
type = 'function estimation';

% 模型训练过程
[alpha,b] = trainlssvm({x_train,y_train,type,gamma,sig2,'RBF_kernel'});

**% 模型预测与误差计算
predict_train = simlssvm({x_train,y_train,type,gamma,sig2,'RBF_kernel'},{alph
