This is one hell of an inspiring course that demystified the difficult concepts and math behind PCA. Excellent instructors in imparting the these knowledge with easy-to-understand illustrations.
Relatively tougher than previous two courses in the specialization. I'd suggest giving more time and being patient in pursuit of completing this course and understanding the concepts involved.

Coding assignment is hard for people who are not familiar with numpy. Would appreciate some material at least going over the basis.

Please change courese material for PCA. It is very un-understandable and assignments are also very tugh as per what is taught.

Focus a bit more on PCA in week 4, week 1 was not very informative and should be assumed as required knowledge for the course

Careful, step-by-step construction of the PCA algorithm with practical exercises and coding assignments.. Very well done...

The course level is very difficult and I think having four week course is not enough to understand the math behind PCA

That's a great online courses can help people have enough background to break into Machine Learning or Data science

The PCA derivation part requires more elaborate explanation so that we can understand the concept more intuitively.

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.

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
автор: Abhishek T•
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
автор: Felipe T B•
Computational exercises could have more support from the professors.

Overall a good course. Very limited introduction to Python though.
автор: Chow K M•
Quite challenging. Need to keep notes for programming assignment.

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