softmax

object softmax extends UFunc

Computes the softmax (a.k.a. logSum) of an object. Softmax is defined as \log \sum_i \exp(x(i)), but implemented in a more numerically stable way. Softmax is so-called because it is a differentiable function that tends to look quite a lot like max. Consider log(exp(30) + exp(10)). That's basically 30. We use softmax a lot in machine learning.
