Professor Dolecek has very engaging lectures and she challenges you just enough to make the class interesting and challenging but not overly challenging. Her tests were very fair and her homework were interesting. Although her rubric was a little harsh if you were trying to go for partial credit. Overall she was a very good professor in my opinion and this was my favourite class during the quarter

class is very approachable and projects are pretty handhold-y, so I had a good time. though if you plan on taking m146 and don't need the intro I'd say just take m146 and don't take this class (m146 encompasses all of m148)

In my opinion, Professor Dolecek is severely underrated on bruinwalk, and I definitely enjoyed her class the most this quarter.
Dolecek's lectures reminded me of those MIT open-class videos that I have seen on Youtube. She was very organized and explained the concepts pretty well. She always answered questions that people had and encouraged class participation. This is why even though her lectures were recorded, most people still preferred to show up in person. I think the biggest downside about her lectures was that she handwrote all her notes on the whiteboard and it could be hard to read sometimes. Regardless, you could always ask her to clarity what each symbol meant.
The exams were okay. I went over her past exams in the test bank, and I realized that her exams used to be a lot harder. Maybe that is why she has such bad reviews on bruinwalk. Anyway, our midterm and final were pretty well designed and similar to the HW, with maybe one or two questions that were kind of challenging/tricky. If you understand the HW, you should get at least a 90 on the exams. Be sure to check your answers though, we did not get to use a calculator during the exams and they did not grade our exams very nicely (you would lose a lot of points for making an algebraic error).
Some of the HW questions involved coding in matlab and there was a matlab project. I did not find coding in matlab particularly difficult with the help of the internet.

Prof Dolecek is one of the best lecturers in the ECE department. This is one of the few upper div classes where I feel that I can fully absorb the content taught in the 2-hour lecture, and be immediately able to do most homework problems (without having to do too much of my own mental gymnastics). Her approach of writing on the whiteboard, having us take our own notes, and asking us lots of questions really helped me stay engaged, but this might not work as well for those who learn better with slides or by watching recordings. She does, however, upload PDF notes from a previous quarter.

Very chill class. Only one exam and it was not math heavy. Good introduction to data science and machine learning.
