梯度RBF的基本MATLAB实现

%记录每次权值调整后的训练误差 ErrHistory=[ErrHistory SSE]; if SSE<E0,break,end for i=1:UnitNum CentGrad=(SamIn-repmat(Center(:,i),1,SamNum))*(Error.*UnitOut(i,:)*W(i)/SP(i)^2)'; SPGrad=AllDist(i,:).^2*(Error.*UnitOut(i,:)*W(i)/(SP(i)^3))'; WGrad=Error*UnitOut(i,:)'; Center(:,i)=Center(:,i)+IrCent*CentGrad; SP(i)=SP(i)+IrSP*SPGrad; W(i)=W(i)+IrW*WGrad;
