erratum ?

Should not be "input" connection?

Hi @MehdiMaboudi ,

Thanks for your feedback. 👍 I agree that this formulation was really unclear. In the upcoming 3rd edition, I changed this sentence to this:

Then it computes how much each output bias and each connection to the output layer contributed to the error. This is done analytically by applying the chain rule (perhaps the most fundamental rule in calculus), which makes this step fast and precise.
