Multinomial logistic regression have assume the IIA (independence of irrelevant alternatives (IIA), IIA assumption: difference logit and probit); but I'm wondering if using Neural network in which the last layer has Softmax activation with negative-log-likelihood as loss function and perform gradient descent also assumes IIA?

If so; is there anyway of make neural net violates IIA ?
