Overall the hardest of the specialization, a though one but great to make sense of all the maths learned so far.

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.

some topic details were just put into readings instead of videos which made it harder than the previous 2

In the PCA module we were asked to code algorithms that were not at all discussed (like KNN). Not cool!

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

There are issues with the submission of the LAB assignment. Otherwise, the course was great

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.

It was a good experience learning this course. Thank you
