MATLAB中的简单前馈(newff)网络 [英] simple Feed forward (newff) network in MATLAB

问题描述

我多次使用ffnew函数，但是当我尝试创建一个简单的前馈网络时，输入向量为P=[1;2;3;4]，所需的输出为T=[1 ;0;0;1].所以我只有一个样本输入向量

I used ffnew functions many times but when I am trying to create a simple feed forward network such that the input vector is P=[1;2;3;4] and the desired output is T=[1 ;0;0;1]. So i only have one sample input vector

代码是

net = newff(P,T,[4 1],{'tansig','tansig'});
net=train (net,P,T);

当我写最后一行时，我得到了:

When I write the last line I got:

??? Error using ==> plus
Matrix dimensions must agree.

Error in ==> calcperf2 at 163
        N{i,ts} = N{i,ts} + Z{k};

Error in ==> trainlm at 253
[perf,El,trainV.Y,Ac,N,Zb,Zi,Zl] = calcperf2(net,X,trainV.Pd,trainV.Tl,trainV.Ai,Q,TS);

Error in ==> network.train at 216
  [net,tr] = feval(net.trainFcn,net,tr,trainV,valV,testV);

推荐答案

如果使用MLP或RNN创建NN，则可以更改功能

If you create your NN using MLP or RNN, you can change the function

a2 = round(f2(LW2 * a1 + b2))或a2 = round(purelin(LW2 * a1 + b2))

然后输出NN(a2)将是二进制的

then the output NN (a2) will be binary
