Can softmax be used for binary classification

Web1 If you mean at the very end (it seems like you do), it is determined by your data. Since you want to do a binary classification of real vs spoof, you pick sigmoid. Softmax is a generalization of sigmoid when there are more than two categories (such as in MNIST or dog vs cat vs horse). WebSoftmax Function. The softmax, or “soft max,” mathematical function can be thought to be a probabilistic or “softer” version of the argmax function. The term softmax is used because this activation function represents a smooth version of the winner-takes-all activation model in which the unit with the largest input has output +1 while all other units have output 0.

Can we use Binary Cross Entropy for Multiclass Classification?

WebNov 26, 2024 · I know I can just use a softmax. I also know that sigmoid can be used for non-exclusive multi-class classification ( Source multi 1, Source multi 2, Source multi 3) - although even then it's unclear whether such multiple sigmoids output probabilities of various classes or again simply a 'yes or no', but for multiple classes.
