Hi,
The “inputDelays”, “feedbackDelays” defines the data that is used to predict output of current time series. If input delay is “i” it implies that the input value at “i” time steps ago(past) is used to predict current output and the same applies for feedback delay.
The condition to define “inputDelays”, “feedbackDelays” are that both must be row vectors with non-negative values in an increasing order. These values need not be consecutive, need not start from a specific number. Also, both these vectors are independent in terms of length and values.
Hope this helps!
