Why do we Softmax at all?

$begingroup$


why take softmax at all at the final layer for multi classification problems? For example softmax of the vector [1, .5]



Is [.621, .379]



I mean if we just took the straight ratio, it'd give me
[.667, .333] instead



Does that really make a difference?



Is it cause the vector can have negative numbers that we softmax things? What benefit do we get from making an odder way to give a ratio/probability to certain numbers as opposed to just taking a ratio of the numbers?
