I’ve started to learn about neural networks recently and I can’t find the answer to this question.
Let’s assume there’s a neural network (fig. 1)
So if the loss function is:
and the derivative is:
if I want to use this to find what k and l (well there’s only one neuron with index l here, but what if there would be more?) should i use in and ?
Sorry if I failed to explain my problem. If something isn’t clear please ask in comments.
