matlab rbf

RBF (Radial Basis Function) 是指径向基函数，在机器学习算法中被广泛应用。以下是一个简单的Matlab代码实现RBF算法的例子:

1. 读入数据集

x=[0 0;0 1;1 0;1 1];
y=[0 1 1 0];

2. 选择高斯函数作为基函数

phi=@(x,c,s) exp(-1/2*(x-c)*(x-c)'/(s^2));

3. 初始化权重值和偏置值

w=zeros(4,1);
b=0;

4. 计算隐层输出

for i=1:4
    h(i,:)=phi(x(i,:),<span class="em">1</span><span class="em">2</span><span class="em">3</span>
