MATLAB: Does the time series output of the NARXNET have less elements than the input

Question

Hi all,

I trained a neural network using narxnet and generated the Simulink block of it using gensim. When I delivered a time series into the input port of the neural network block (and fed back the output to the feedback signal port), I obtained a time series as the output with a length that was less than my input size. My original input time series size is 60001×1, but my output is only 61×1. Why does this happen?

Thank you,

Answer 1

Because the first few data points are used as delays.

Hope this helps
