我目前有一个错误,我无法通过这是短代码和所需的一切,以便对我的问题有一个大概的了解

end

在算法的火车部分,它给了我一个输入错误,这对我来说很奇怪。
错误消息:
使用trainlm时出错(第109行)输入数量不匹配 net.numInputs。
网络/火车出错(第106行)[net,tr] = feval(net.trainFcn,网,X,T,僖,艾,EW,net.trainParam);
我设法解决了所有工作后,这里的代码适用于任何在未来gl中有相同问题的人:D:)。

这个帖子可以关闭thx:)
答案 0 :(得分:0)
我认为你在混合单元格和数组格式方面遇到了一些问题......
尝试替换:
net = train(net,CeDam{j},CeVrem{j});
由:
net = train(net,cell2mat(CeDam{j}),cell2mat(CeVrem{j}')');
AND:请删除i
中的无限循环,添加i=i+1;
或将while
循环替换为更自然的for
循环,例如
for i = 1:10
for j = 1:10
if i~=j
net = train(net,cell2mat(CeDam{j}),cell2mat(CeVrem{j}')');
end
end
end
AND:你在循环中使用i
在哪里?我想那里缺少一些东西......
