Use a trained NARX network on new input data.

Hi, I trained a NARX network and now I am trying to use the trained network on new input data to predict the result, but I can't make it work using the "net" command. Anyone has an ideia about what I have to do?

Hi @Gustavo Santi,

In order to make predictions using a NARX network, you need to prepare delayed inputs.

Please refer to the following official documentation link for more information:

https://www.mathworks.com/help/deeplearning/ug/design-time-series-narx-feedback-neural-networks.html

You can use "preparets" function for preparing data with appropriate delays. Here is the documentation link for the same:

https://www.mathworks.com/help/deeplearning/ref/preparets.html

Here is a sample code snippet for your reference:

newInputData = ...;
newTargetData = []; % Use empty if you don't have target data

[Xs, Xi, Ai, Ts] = preparets(net, newInputData, {}, newTargetData);

predictedOutput = net(Xs, Xi, Ai);

% Display the predicted output
disp('Predicted Output:');
disp(predictedOutput);

Hope this helps!
