She changed to recorded (visual also) for the lectures this quarter which was great. A lot of repetition in the slides; good for review but also felt like this course was stretched out in some areas.
Projects were all right, TAs could be fairly critical in some areas but if you completed it, usually it would be fine. Homeworks were also relatively okay, with some derivation work being the hardest stuff in my opinion, so not bad.
Final was pretty fair all things considered. Kind of long but not too bad either. Discussions were usually more on content review, so skippable unless you also had something to ask about projects.

Lecture audio is recorded. It's a relatively chill and slow-paced, so it's a good intro class. HWs can be a bit tedious, projects were fun, and the final exam is very easy. It's a fun class to take.

This is my second class taken with Dolecek, and it was pretty easy in my opinion, but I still enjoyed the topics a lot. It certainly helped that the TA's left solutions from the previous quarter up for the first two weeks LOL. There is only one exam (final) and its only worth 20% of the grade, but the median was still very high at 97%.

My only complaints about the class were that the recorded lectures were audio only (I never attended class), and that the TA's this quarter were extremely slow at doing ANYTHING, but overall I enjoy Dolecek's classes a lot!

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)

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

a very straightforward class -- watch the lectures and follow instructions and you will get an A
