The softmax function
WebAs an aside, another name for Softmax Regression is Maximum Entropy (MaxEnt) Classifier. The function is usually used to compute losses that can be expected when training a data … Web3. I always thought it was called softmax because it is differentiable ("soft") at all points for all elements of the input vector. This explanation would be analogous to what makes the softplus function, f ( x) = ln ( 1 + e x), the "soft" version of f ( x) = max ( 0, x) Share. Cite.
