Typo on page 28

[achang2]

In the last paragraph before section 2.8 on page 28, the sentence starting with "A large part of 'debugging' is missing a parenthesis. The full sentence is as follows: A large part of “debugging” machine learning (covered more extensively in Chapter 5 involves trying to figure out where in this sequence the biggest losses are and fixing that step.

but I believe it should be:

A large part of “debugging” machine learning (covered more extensively in Chapter 5) involves trying to figure out where in this sequence the biggest losses are and fixing that step.
