There seems to be an editing error in the explanation for answer 1 to Question 11 in the Chapter 1 quiz. The explanation says (emphasis added):
Correct! When applying Transfer Learning, the bias in the pretrained model used perspires in the fine-tuned model.
I think “perspires” should be something like “persists.” I’m pretty sure bias cannot sweat. Unless “perspire” is being used in some metaphorical way I am not familiar with (which would surprise me, as a pretty educated native English speaker), this looks like a mistake.
