| He says repeatedly "You don't need math", and stuff like that. This is not insulting. That man is my hero, and I deeply respect him. But his 2019/20 course was riddled with such statements. He repeatedly said that one doesn't need math, and showed tools like drawing math symbols on a website to learn their names and ride on that. No further math needed. It's like you can wing it in Deep Learning without learning Math. His behavior throughout the course reinforced this attitude. It is harmful for new learners. But I am fortunate that I didn't learn from that, but learned from some successful alumni example that Howard gave. One woman who was also a musician ('19/'20), she made it big, but Howard mentioned that she did the Ng course, and also read the Goodfellow book. So, I took the cue, and did DL the proper way. Anybody I know in DL made it because they know the Math. There are some influencer types in fastai community who has 10ks of followers and shills stuff and do media stuff. Other than that 1-2 people, everyone who made it in DL, did it because they knew the math. So, I think that people might get the wrong idea hearing from Howard that "you don't need math". This is one fault I find. It's not like I dislike him. I like the rest of him. I love his attitude on almost all other things. I love Jeremy Howard, and he is my hero. |
You don't need the math in the beginning to train a model and get first results. Later, you will need the math and Jeremy clearly knows the math.
He gives a great example: In sports, you don't start with learning about physiology and train individual muscles etc. (I paraphrase), you start playing basketball or baseball or soccer, and understand the overall game. And if you like it, you can then become better and better and get deeper and deeper.
It's not helpful to start with linear algebra if - what motivated you - was the application of ML. We lose people who could have otherwise become experts later.
