I have taken the lectures up to Chapter 7 Clustering. It took about 3 weeks to study after work. I purchased both the lectures and the textbook. First of all, it was great to be able to systematically review machine learning. The explanations are also clear. When I read the book, I could really feel how much effort was put into writing it. Above all, I liked that the author answered questions in a very detailed and friendly manner. However, it is not suitable for those who do not know anything about machine learning. Those who know basic machine learning should take the course. I look forward to other advanced lectures by the author, such as the Kaggle Advanced course! Thank you.
