The full title of the book is "Algebra, Topology, Differential Calculus, and Optimization Theory For Computer Science and Machine Learning" by Jean Gallier and Jocelyn Quaintance
Can you finish 2000 pages of math textbooks in a four year math degree???
Also you seem to arrive at your first ML application after 1500 pages or so.
I’m reminded of a class at my university on “early Christian literature” where the professor announced on the first day that despite the title they would actually start in 3,000 BC.
Sigh.... I'm not sure what the audience for this book is. Anyone looking to learn the math behind Machine Learning would be much better served learning just what they need and expand their horizon as the need arises. I'm not sure anyone really learns this stuff by just reading a 1000 page book, learning happens nonlinearly, you learn a bit of A, then a bit of C, then a bit of B, and try and connect them together. It always reminds me about the story how Heisenberg didn't know what matrix multiplication once when he came up with his version of quantum mechanics. You don't need to know everything to make an impact.
For a book for adult learners I recommend (and am working my way through) Ivan Savov's No Bullshit Guide to Math & Physics. Here's a link to a sample from the author's site. I find it a great resource for brushing up on my math(s) to explore audio DSP.
