can some one tell me why my ytrain and ytest is zero?
my labels are 100, 200 and 300
iam trying to find training error and test error but it gives me zeros
clc
clear all
close all
filename='FIFA2.xlsx';
A =xlsread(filename);
[m,n]=size(A);
T=A(:,1);
data=A(:,(2:end));
rows80=int32(floor(0.8 * m));
trainingset=A(1:rows80,2:n);
testset=A(rows80+1:end,2:n);
t=trainingset(1:rows80,1);
t_test=A(rows80+1:end,1);
net= newff(trainingset',t');
y=sim(net,trainingset');
%net.trainParam.epoch=20;
net= train(net,trainingset',t');
y=sim(net,trainingset')
y_test=sim(net,testset')
p=0;
y1=hardlim(y');
% hardlims(y_test);
for(i=1:size(t,1))
if(t(i,:)==y1(i,:))
p=p+1;
end
end
ytrain =100*p/size(trainingset,1);
q=0;
y2=hardlim(y_test');
for(j=1:size(t_test,1))
if(t_test(j,:)==y2(j,:))
q=q+1;
end
end
ytest=100*q/size(t_test,1);
