MATLAB: How can i improve the performance of a closed loop NARX neural network

close loopDeep Learning ToolboxMATLABmsenarxneural networkstutorial

I've created an open loop NARX network for system identification with (ntstool) toolbox. My open loop network's performance is 1e-07 but when I close the network the error(mse) highly increases (around 1.15). Is there any way that I can do for improving the close loop performance

Try narxnet. Use the autocorrelation of the target and the crosscorrelation of input and target to find the lags that are statistically significant for input and feedback delays.
Hope this helps.
