Can someone please help me with backpropagation?

Question

I try to create such an algorithm myself and get a bit confused.
 I would be happy to any help :)

Answer 1

I sadly can’t really help you over this app because it doesn’t support latex but I think this is a really good explanation of what’s going on http://neuralnetworksanddeeplearning.com/chap2.html if you still have problems after reading it I recommend you ask on stackexchange. Look at this thread there https://meta.stackexchange.com/questions/130524/which-stack-exchange-website-for-machine-learning-and-computational-algorithms to find out where to ask your question

Answer 2

Thank you very much!

Answer 3

How much math do you know and where did you get stuck?

Answer 4

I understand most of the mathematics. Even though I don't know how to deal with partial derivatives. I got stuck as I began to work on changing the weights in the hidden layers. I didn't understand how to calculate the error of each weight and how to change it.
Thank you!
