How to learn the theoretical underpinnings and gain the practical to powerfully apply these techniques to new problems, is an important question for machine learning course. This paper proposes a case- study teaching method. In the class, students get

hands-on experience with machine learning from a comprehensive practice case, and acquire the complete knowledge system by adjusting the steps and parameters of an integrated case. The practice results show that this method can effectively help students understand theoretical knowledge and improve the practical ability.
