Web12 Jun 2016 · $\begingroup$ I think it's incorrect to say that softmax works "better" than a sigmoid, but you can use softmax in cases in which you cannot use a sigmoid. For binary classification, the logistic function (a sigmoid) and softmax will perform equally well, but the logistic function is mathematically simpler and hence the natural choice.
