Question

MATlLAB 实现BP神经网络 下面的语句都是什么含义
net=newff(minmax(minp),[8 1],{'tansig','purelin'},'trainlm');
net.trainparam.show=25;
net.trainparam.goal=0.0001;
net.trainparam.epochs=1000;

Answer 1

net=newff(minmax(minp),[8 1],{'tansig','purelin'},'trainlm');
newff初始化神经网络,minmax输入矩阵的最大和最小值,8隐层数,1输出层数,{'tansig','purelin'},'trainlm'这三个是训练函数.
net.trainparam.show=25;
神经网络每迭代25次在图像中显示一次.
net.trainparam.goal=0.0001;
训练的误差精度
net.trainparam.epochs=1000;
最大迭代次数.
