Hello,

I am quite new to Matlab and have a question.

I am trying to predict a timeseries using a NARX net.

What does it mean if my MSE validation error is zero?

Both test and training have dessent values.

Kind regards Natascha

Hi,

MSE = 0 on validation data set means your model was able to predict all the validation data correctly. This might indicate over fitting. If you would like to plot and visual, then I would suggest trying out the plot functions in the link given below:
