Hello,
I am just wondering why, for the function "softmax" in the practice exam of 2020, we don't use the sigmoid function ?
Thanks in advance.
Hi Charles,
Good catch! There is a typo in the lecture notes, the correct version is without the sigmoid. I refer you to Christopher Bishop's book for this:

So the softmax function in the practice exam is correct.

Hello,
Are we supposed to know the softmax function. If I am not mistaken we haven't seen this function during the lectures.

Hello,
You saw it as part of multi-class logistic regression in the Linear Classification lecture.
