Hi

While caculating a values in softmax we took exponential of z values. Why we just not sum all possible z values and divide zj to this sum ?

Is there a reason to make using exponential values instead of actual values.

Thanks in advance / Cemal

The equation using exponentials creates a gaussian probability distribution.
