I have a Narx network with 6 external inputs. These have a 1:2 delay on them. I also have a feedback loop for multi-step ahead prediction with a 1:24 delay on them. Does this mean I have 12 external inputs (x1(t),x1(t-1)...x6(t-1)) and 24 'feedback' neurons (y(t-1),y(t-2)...y(t-24)) totaling 36 input neurons?
inputDelays = 1:2;
feedbackDelays = 1:delay;
net = narxnet(inputDelays,feedbackDelays,hiddenLayerSize);
