Hello I have a data set as input for ANN, some of the value is equal to zero, lets say column number 3. Some of rows has zero value on the that column and other with nonzero value. Now, how I set up condition that will not read row that has zero value on column 3 on my prediction function.
prediction = zeros(1000, 1);
j = 1;
while (j<=4)
prediction(j,1) = cuRnet(input_data(j,:)');
j=j+1;
end

E.g., if you want to test for that condition within the loop itself:
if( input_data(j,3) ~= 0 )
prediction(j,1) = cuRnet(input_data(j,:)');
end
Or you could create a test result for that column prior to the loop:
col3 = inputdata(:,3) ~= 0;
and then use that result within the loop:
if( col3(j) )
prediction(j,1) = cuRnet(input_data(j,:)');
end
