Feldman was incredibly helpful and knowledgeable. Lectures are clear and recorded making it easy to review. She responds to emails and has plenty of office hours. There is a weekly quiz which can be retaken after she reviews the answers in OH. Final proj is 50% of the grade but guidelines are clear & she has a lecture where she does it step by step

Raya is a very knowledgeable and firm instructor, with her support proving useful most of the time. Said support is practically necessary to pass the course, due to extremely dense lectures and assignments, difficult online quizzes (which she allows retakes on), and a project worth half of the grade. But she provides these tools useful to succeed.

Tough but very kind and patient professor

Raya is amazing, but you have to work/ study hard.

Prof. Feldman is very helpful in and outside of classroom. She provides all lecture notes, slides and example questions. The lectures are a bit math-heavy but the formulas and concepts needed for homework/quizzes are given explicitly in the course materials. Also she gives a complete guide of final project and you can meet with her in OH for help.

Truly excellent instructor.
