It's not clear to me who the target audience is for this book. As someone with a graduate degree but not a mathematical background, I'm comfortable reading academic papers, but a lot of this feels over my head. So it reads to me like it's a quick refresher or reference for people who already learned this stuff at some point, rather than an introduction. But the preface says this is to be "a book on Mathematics for Machine Learning that motivates people to learn mathematical concepts."
As a sidebar, it has always seemed to me that there is a giant gulf between truly beginner-friendly math books, which are aimed at children, and introductory math books aimed at adults. The latter almost always read like foreign language textbooks where you must first know the language before you can start, while the former are too elementary. I'd love to find "College level Math for English Majors" or something of the like, if anyone knows of such a book :)
