By contrast, let's pretend instead that the example in Fig. 5 .2 was actually negative, i.e., y = 0 (perhaps the reviewer went on to say "But bottom line, the movie is terrible! I beg you not to see it!"). In this case our model is confused and we'd want the loss to be higher. Now if we plug y = 0 and 1 − σ (w • x + b) = .31 from Eq. 5.7 into Eq. 5.12, the left side of the equation drops out:
