I had to comment to balance out the one single negative comment. It's true that there's some problems with the printing but the comment is irrelevant for the book's content. I think that the first volume is a great summary of subjects that junior data scientists must know. Also, I being a great believer in Occam's razor: if you managed to explain (or at least to remind) how does an SVM works in 2 pages instead of 20 pages - then you did a good job. The internet (and the library?) is full of details for further research.
