MATLAB: Feedback Delay of a Layer Recurrent Neural Network with multiple Outputs

layer recurrentlayrecnetmachine learningneural networks

My Neural Network has multiple outputs and I'm trying to find the right Feedback delay so I'm computing the correlation of my output vector, but I don't know if I have to calculate the autocorrelation : nncorr(Output1,Output1) or do I have to calculate the crosscorrelation: nncorr(Output1,Output2) etc … because it's a neuralnet with multiple outputs?

The only feedback to the input is from the hidden layer.
However, given the input, there is no way to estimate that signal. Ttherefore, there is no apriori way to esrimate the significant crosscorrelation delays.
