Programming Machine Learning: missing index in formula (p. 71)

Hello, I think there is a typo in the formula for the gradient of the mean squared error.
Shouldn’t it be x with index i like it is in the formula above?

This sure looks like an oversight on my part. Thank you, @HofmT! There are no new printings of the book scheduled for now, but I took a note to fix that missing index in the next update.
