Professor Lorenzelli is nice and professional. He provides well written (as in organization but maybe not in handwriting) notes. He would try his best to clarify things in class, and he can be easily accessed outside of class. Perhaps more importantly, he is a very kind human being, that he would try to accommodate everybody's needs and you could always talk to him if you need anything special (ddl extensions and etc).

Professor Lorenzelli is a sweet guy and he's really understanding of student struggles. I had him for 102 and 113, and will be taking him again for 114 because I like him so much :) He was very accommodating during COVID online learning. The online class was very well-structured, (20% homework, 40% best 4 of 5 quizzes, 40% final project). Shoutout to Alex Johnson the GOAT TA.

Professor Lorenzelli is pretty funny but sometimes he gets really annoying. His lectures was complete but he also gave us professor's Fragouli notes which I think it was way more useful . Weekly homeworks were straight forward and good practice of course material, however the biweekly quizzes were really hard, time consuming, and weighted 40% of our grade. First week of class he said we either have a take-home final or group project which we ended up with 4 question project that took lots of time and somewhat was confusing and the grading on project was horrible. Overall I wouldn't recumbent him for this class or any other classes, but take professor Fragouli at any cost.

The professor was very approachable for help. He would always stay after class and answer anybody's questions with his best effort. His notes are a bit messy but if you examine closely enough, you can understand wat's going on. I mostly used it for review when doing hw and quizzes. I would say I learned more from the TA's discussions and slides tho since I feel like that was more organized and easy to follow. The homework was pretty hard and would take a long time to finish but definitely doable especially for many times you can find very helpful hints or occasionally even pretty much answers on piazza or in discussion slides. The quizzes were also pretty hard but definitely doable if you spend enough time thinking or reviewing materials while doing it. The only thing I didn't like about the class was the final group project. We had to do on Google collab that was laggy so it was hard to work together with other people, and also hard for people with not much python background. It took so much time for us to finish, but at least they gave us extension. I would have 100% loved the class if we had a final exam instead of the project, but overall the class was great.

This was the quarantine quarter - so take everything I say with a grain of salt.
I absolutely loved 102 (taken with Kao), and was looking forward to this class. However, I stopped attending lecture (only for this class) around halfway through the quarter.
Lorenzelli is very sweet, and cares about his students, however his lectures are disorganized and hard to follow. This is compounded by messy handwriting and his soft spoken manner. I find it very helpful when teachers give you headings, or explain why they are about to do something, but with Lorenzelli I often found myself backtracking in lecture, trying to figure out why we just did all that algebra while simultaneously trying to figure out what we just concluded as I try to decipher his handwriting.
However, he did post Christina Fragouli's old lecture notes, and these are very clear and helpful.
The homework's for this class were fun, manageable (especially when zooming with friends), and helped me understand the material. They also involved a coding component :)
Grading scheme was odd - 40% multiple choice quizzes, and 40% a project that was basically choosing the parameters of functions.

Professor Lorenzelli is a really nice lecturer and very understanding. Because of COVID, your experience with 113 might be very different. So instead of a midterm and a final, we had quizzes every other week, weekly homework, and a final project. Lorenzelli is a softspoken person, so at times, the lectures can be a little difficult to understand what prof is trying to prove, but the professor provided Prof Sayed and Prof Fragoulli's notes which are a good resource to review material covered in lecture. The project was 3 question (1 optional) about signal identification, reconstructing a signal's phase, and redoing it with neural networks. The prof and the TAs were overall very accommodating considering this quarter was cursed af.
