Want an A? Better aim for 94+, because apparently 93 isn't enough. Even Elon Musk might have trouble getting an A here. Expect quizzes almost every week, heavy homework, and exams that are much harder than expected. Lectures and slides are extremely dry, with little guidance about what actually matters. It is hard to stay engaged.Rate My Professors ↗
There is a quiz almost every week, the homework load is heavy, and the exams are very difficult. A 94 is only an A, so even Elon Musk might struggle to get one. The lectures are boring, the slides are dry, and there is little guidance on what to focus on. Most people seem to stop paying attention during class.Rate My Professors ↗
Pick a religion and start prayingRate My Professors ↗
Probably one of the worst instructors on campus. Instead of teaching us the content, he assigns YouTube videos for us to watch which are insanely complicated and difficult to understand. He assigns a ton of homework every week, doesn't release adequate practice material, doesn't tell you the grade boundaries, and administers four total exams.Rate My Professors ↗
Please avoid for your sanity. I enrolled into the class with curiosity about the subject, and I am now finishing up realizing he managed to make me hate it. LOTS of homework (due before exams) where python is used (python knowledge is not a requirement), exams are impossible to finish and there are hard proofs.Rate My Professors ↗

Past student reviews · Grigoris Chrysos
Grigoris Chrysos taught a proof-based course on ML foundations covering tensor decompositions and statistical learning theory. Students reported conflicting experiences: one described clear lectures and challenging assessments, while another criticized illegible notes, unrelated homework, and the professor's absence for a month.
