编程练习的质量不够高，不管是编程练习本身的代码逻辑、注释、练习的质量还是在答疑区课程组的答疑都不能尽如人意，对于编程练习并不很满意

Great course! It could have elaborated more in the week 4 PCA

feels like it progresses too fast. otherwise great content

Course was challenging , but learned the maths behind PCA,

Good content, just need to fix the assignments' platform.

It was a good experience learning this course. Thank you

Not 5 stars because are errors in the automatic grading.

Excellent course, but the last assignment wasn't obvious

This course was a fair overview of a very complex topic.

It is very informative and hands-on based Course for PCA

Not as good as the other two courses..but interesting!

Mathematically challenging, but satisfying in the end.

great material but explanation are a little bit messy

Thank you for this course , hope to learn more !

Good course, but requires mathematical background

Good but slightly less deeper than the other two

The instructor is great. HW setup sucks though.

its was soo hard your background not from math

Best course for machine learning enthusiast

The last assignment could use improvement.

a really good course but also really hard

Good for intermediates in linear algebra.

Too much non-video lectures (lot to read)

Overall very fun and make a little dizzy

The last course could have been better.
