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.

This course was definitely a bit more complex, not so much in assignments but in the core concepts handled, than the others in the specialisation. Overall, it was fun to do this course!

I learned a lot in this course, though the last week was somehow hurried and the lecturer didn't spend enough time to piece the whole stuff together.

Course addresses important subject, but I worth like to have more in-depth explanation of the mathematics by the instructors and more examples.

Felt like explanations in this course were a bit confusing, but otherwise, it was a very interesting course. Thank you so much for doing this.

This was a very hard course for me. But I think the instructor has done the best possible he can with presenting and explaining the course

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

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

-Some of the contents are not clear.
+It gets great intuition for new learners in machine learning.

Lot of Math. Couldn't get proper intuition regarding PCA, was lost in understanding math equations

I agree with the others. Course didn't merge well with the 1st two which were perfect!

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

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