I personally loved Lorenzelli. He is a very nice person and he really loves what he does. It is refreshing to have a professor that isn't a pompous ass.

I learned a lot from the class and found it all very interesting. I couldn't ask for more.

TAKE THIS PROFESSOR

definitely by FARRR my favorite professor I've had so far here at UCLA. Unlike many of the other EE professors who tend to be geniuses and therefore extremely conceited and unwilling to help, professor Lorenzelli himself admits that 'many of you are probably smarter than I am' and is truly concerned and passionate about teaching. Although he speaks in a soft-ish voice, which I do admit, has had me falling asleep some of the days, he is extremely approachable and a warm caring person in general. Furthermore, he is very flexible and will delay coursework to make sure that we have fully learned the material! If you ask him a question on a homework problem he will literally tell you how to solve and check your answers for you if you are having serious trouble in the class. He even gave us his # to have us text him LOL

Professor Lorenzelli is definitely one of the nicest professors I've had. If you pull up to office hours, he's more than willing to help you out. He's very down to earth and is very aware that this class is extremely hard, and tries to be understanding as possible. I would say the content itself was honestly very, very hard for me to understand. I'm also not an electrical engineering major, so that could be a part of the reason. I did go to all the lectures, but it's very conceptual and integral heavy (big emphasis on integrals). The youtube channel Neso Academy helped me out a lot with understanding the concepts. The homework isn't too bad I would say, but it does take a while to complete. The midterm wasn't too bad and it was doable; the average was 75%. The final was honestly pretty hard, as it was very calculation heavy and there was more emphasis on Fourier Series content (which I didn't really understand that well). Average for final was a bit lower than midterm (high 60s I think). The class ended up being curved, but I'm not sure by how much. The grading distribution is 15% HW, 35% Midterm and 50% Final. There was some extra credit for being active on Piazza, but they didn't say the exact amount. In summary, professor Lorenzelli is a very nice man, but the class itself is extremely difficult so I would not take it if not needed.

Lorenzelli is one of the nicest professors I've had in the EE department. He's super sweet and really cares about student learning, and his office hours are really helpful. The course material was pretty difficult for me and a lot of times I didn't understand what was going on, though.

I got a B- in the course and I worked my butt off, but my exam scores were absolute garbage and imo not deserving of the B- in comparison to the rest of the class. The professor himself is very caring and if you are willing to put in time with him during office hours he will do his absolute best to help you. During lecture, his voice can be soft and you might need to tell him to speak up, but he very humble about any mistakes he does and I highly suggest to take him. Exams are very difficult, or at least for me, they were.

Very chill and nice professor. He teaches from slides that contain a summary of the topics and the skeleton of some worked examples, and elaborates on these during lecture, working out the examples on the whiteboard/chalkboard. His explanation of topics isn't bad, but the topics covered in this class tend to be abit more abstract and take some thought to grasp anyways. He tries to make the material as interesting as he can, but there's really no getting around the fact that this class is boring. Only major issue is that he talks quite softly and does not write very large, so getting a spot in the front was a must for me personally. As for grading, its based off one midterm, homework, and the final only. His homeworks are pretty difficult and graded somewhat harshly, so you'll definitely want to check your answers with others on it. I would say the tests are challenging, but fair. The averages for both the midterm and final I believe was in the high 60s. Overall, I have nothing bad to say about the way he ran this class. Definitely recommend.

Lorenzelli is clearly passionate about teaching and making sure students are learning. Lots of example problems in class. Discussed several applications to industry as well. Midterm was easy, final was very challenging. Review all homework problems, problems from lecture, etc. to do well on exams. Matlab on the homeworks were tricky but weren't graded for accuracy (TA personally told me he would give full credit if you made a decent attempt). What makes the class hard is needing to understand the concepts deeply while still being able to doing computations with complex numbers quickly and accurately.

As a disclaimer, I took the class in spring 2017 and dropped it after a week (after going to the first 2 lectures), so my opinions may not accurately represent this professor. The 1st lecture was fine. However, the 2nd one was terrible. He talked about linear, casual, and invariant signals and did provide some example questions, but the annoying thing was that he went through each one without really showing you how to do it; he just talked through them, and I cannot understand what he was talking about, in spite that I am English proficient and had taken all the pre-requisites with an A in each one. But what made me even more frustrated was his attitude, not his lecture. When I mentioned politely to him during the break that the he was going too fast, he not only did not care at all, but also responded by saying that the material would only get worse. Needless to say, the latter half of the lecture was the same as the previous half. It seemed to me that he had lectured horribly yet thought that he did not do anything wrong. I think he should really work on understanding the students' complaints from the students' perspective, not his own.

Very lovely man. Go to the office hours, and drink plenty of coffee before and during the 2-hour lectures - you'll probably fall asleep otherwise (he's quite dry in class and the content isn't exactly riveting)

I took EE205A. The reason I write the review here because I can not found professor Lorenzelli in course EE205A. However, my point is that the professor Lorenzelli is really good professor. He want explain much more detail you want to know. When you talk to he, he always explain very well. In the end, the lecture he give us are very useful. I use those math knowledge to solve the machine learning project. Highly recommend the professor Lorenzelli !
