Programming assignments are a little difficult. Background knowledge of Python is recommended for this course.

Very difficult course, make sure to do the prereq courses first and understand everything from those courses.

The programming assignments were quite challenging. Some part of the course can discuss this aspect as well.

It is a good course with hard programming, but the assignments could be improved. The forum helps a lot.

The derivations of some concepts have been more vague compared to other courses in this specialization.

Very challenging, could have used a few more videos to really explain or give a few more examples

The structure could have been better. Some of the weeks were too crowded as compared to others

very difficult course. But I hope that it will be useful fore my machine learning studying

still have room for improvement since lots of stuffs can be discussed more in detail.

Harder than expected, the content is good and is well worth the struggle!

This course is full of mathematical derivation, so it is kind of boring.

We need more basic example and exercise before taking graded assignment

Computational exercises could have more support from the professors.

Overall a good course. Very limited introduction to Python though.

Quite challenging. Need to keep notes for programming assignment.

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.

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.
