Neural Network Softmax (cross-entropy) Backpropagation Derivation Calculus
1
$begingroup$
I am trying to derive the backpropagation gradients when using softmax in the output layer with Cross-entropy Loss function. Can someone please explain why we did a Summation in the partial Derivative of Softmax below ( why not a chain rule product ) ?
Thanks
