David, I followed every instruction in the README, i recorded my first Training Set, which according to Driver was in /tmp/nnrccar...features, i copied that file to my mlclass/ex4 folder and i executed parse.py, then the nnrccar.m file, after 14 secs while fmingc was running, i got an error:
Training Neural Network...
error: subscript indices must be either positive integers or logicals.
error: /home/andfoy/mlclass/ex4/nnCostFunction.m at line 78, column 13
error: at line -1, column -1
error: /home/andfoy/mlclass/ex4/fmincg.m at line 77, column 12
error: /home/andfoy/mlclass/ex4/nnrccar.m at line 56, column 20
Exactly in this line:
% y(k) - the great trick - we need to recode the labels as vectors %containing only values 0 or 1 (page 5 of ex4.pdf)
yk = zeros(num_labels, m);
I executed the ex4 exercise nornally, and it worked, so i don't know why my training set is throwing that error
Thanks in advance
