I've currently listened to up to lecture 9, and I'm very satisfied. At first, typing the code 10 times each... takes quite a long time, but I think it's a necessary process. Since I'm not used to pressing English letters or shift keys while typing operators, it takes time, but I think getting familiar with these things will help me code faster later on. And you provide excellent motivation as well. Rather than just following along with Python typing, you teach using practical formulas that will actually be used in deep learning later, such as variance, mean, standard deviation, and other things like L2 norm. Although I don't understand them well yet, I think they'll be a great help later. There are many other course reviews I'd like to leave, but I need to hurry to the next lecture, so I'll end here. I'll come back to leave another review when I get the chance after finishing all the lectures! Thank you for providing such a good course at an affordable price!
