By Amazon Customer This books looks awesome but in the Kindle version all the equations have missing elements. For example there is a white square box instead of chracters/numbers. This totally makes the online version of the book unreadable. Please help to fix this in the online version,

1 of 1 people found the following review helpful. A nice collection of short and brief topics ready to study By Christian S. A nice collection of short and brief topics ready to study. It has code examples, they are not very detailed, but they give you enough as a refresher.

0 of 0 people found the following review helpful. Great little book By Client d'Amazon 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. It's short and to the point.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.
