I wish to learn more about how to actually use and apply ML, but basically all the lecture is about theory and math. The homework is heavy, especially the coding part is barely taught in class. Her voice is so small and with a heavy accent. Instead of wasting two hours, you could just learn the lecture yourself online.DS4400 2026-02-26 05:40:02 +0000 UTC
Thick accent and can not understand the first thing she taught. The type of professor to push the midterm 4 days ahead with less than a 24 hour notice. Lots of homework and not understanding at all. Do not take her and I doubt northeastern is going to keep her much longerDS4400 2026-02-24 04:32:33 +0000 UTC
I was hoping I would love this class and learn a lot about implementing cool machine learning algorithms on cool datasets. The course material is bad(only have done GD after a month) and she is so boring that its impossible to pay attention. I genuinely hope she reads this and tries to do better.DS4400 2026-02-12 17:22:25 +0000 UTC
Lectures are unreasonably complex, spends the whole class proving formulas rather than showing us how to use them which is what is actually on the homework assignments/quizzes. I learn more about the material from a google search. Gives random pop quizzes at the beginning of class and calls out students who are even two minutes late.DS4400 2026-02-10 20:00:13 +0000 UTC
Prof. Oprea is incredibly knowledgeable in her field. The material can be dry at times, but is in depth and thorough. The homework can be very long, but she and the TA's are easily accessible. She listens to students requests and wants us to succeed. Most of the grade is a Final and Final Project.DS4400 2020-11-20 15:35:47 +0000 UTC
