I would like to thank all of the great people that made this book possible. Without any of you, this book would only exist in my mind. I would like to especially thank all of my editors at Packt Publishing: Vibhuti, Athikho, Martin, and so many more, as well as my reviewer, Vadim, a renowned machine learning researcher from MIT. I would also like to thank all of the reviewers of the code of this book. Without them, this book would be harder to read and apply to real-world problems. Last but not least, I'd like to thank all the readers for the support they provided, which encourages me to continue with the second edition of this book.
