In the matlab NARX model, when we chose train/validation/test data randomly, does this random division happen in every epoch or just once in the beggining? I am talking about the command : net.divideFcn = 'dividerand' Thank you in advance.

I guess just once in the beginning.

The good thing about these differences in opinion is that they can be tested and compared.
If you do so, remember
1. The results of regression/classification examples are
not necessarily valid for timeseries
2. The results for the three types of time-series may
not necessarily be the same.
Hope this helps.
Greg
