I bought the book "The Complete Guide to Python Machine Learning" and followed it from beginning to end, and I felt like I understood something, so I decided to try Kaggle as a hobby, so I listened to it. After listening to it, I learned how to approach the actual competition, which was good. And I also realized that I wouldn't be able to see the rankings if I just slogged along by myself...ㅠㅠ I think I'll just have to form a team, divide up the work among several people, work on each data, and put my head together to figure out which features are important and do feature engineering to barely keep up. Thank you for the great lecture!
