The input values can be positive, negative, zero, or greater than one, but the softmax transforms them into values between 0 and 1, so that they can be interpreted as probabilities.
Webbprobability vector. A probability vector with rcomponents is a row vector whose entries are non-negative and sum to 1. If u is a probability vector which represents the initial state of a Markov chain, then we think of the ith component of u as representing the probability that the chain starts in state s i.
