Errata on Training neura networks via backpropagation?

[fabianofa]

Hi there, I believe there is a mistake on the equation for

The left side of the equation should be:

$ \frac{\partial L}{\partial w_{1,1}^{(h)}} $

instead of:

$ \frac{\partial L}{\partial w_{1,1}^{(out)}} $

Otherwise it wouldnt make sense to include the hidden layers partial in the equation, since the $ \frac{\partial L}{\partial w_{1,1}^{(out)}} $ was already defined a couple of paragraphs before.

Thanks for the feedback. And you are right, this is incorrect:

I am seeing it's already in the errata here at https://github.com/rasbt/machine-learning-book/blob/main/ERRATA/README.md so I am closing this issue. Thanks for reporting!

My apologies for the duplicated entry. I might have an older version of the repo, as I looked to that readme first and couldn't find anything, but it completely slipped my mind to pull. Thank you for confirming.
