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.

Amazing topic, great teachers and nice videos, but assignments can be slightly frustrating and some aspects (matrix calculus, derivatives, etc.) are really expedited... Still worth your time!!!

It's a shame. There's lots of good material and I learned a lot. But a staggering amount of time was wasted figuring out gaps in the instructions - portions felt more like hazing than teaching.

The derivatiion of the PCA in the last week can be broken into 2 weeks with different programming assignments to get a closer and more confident understanding of the PCA method.

I would ask the lecturer to go on more detail on the explanations and do (more) examples.
The lecturer tends to skip a few steps during calculations and demonstrations.

The week 2 code was more difficult than the other weeks. The forums are no longer attended by the professors. The access to materials from IC is great.

The knowledge introduced in this course is really helpful. However, the programming assignments are very time consuming and not necessarily relevent

Decent explanations of PCA idea, but assignments do not provide a clear feedback of what is wrong with the implementation util you get it right.

The First 2 courses of this specialization were very good. I really wish the instructor for this course went into a little more depth.

Average quality with low regard for intuition. Content is often Wikipedia pages or references to own content (chapters of own book).

The course was highly challenging. I wish some of the explanations were detailed and the assignments had better instructions.

The professor of other two a way better. This one skips some steps in some explanation that makes the tasks hard to do

worse than previous courses of machine learning specialization. Really confused me when introduced the inner products.

Honestly this course is the one worthing attempting. However, last week's content is really messy and challenging.

many steps are not clear enough that I have to spend a lot of additional time to figure out the details.

Tutor is not clear and concise on the concepts. Need more examples for Week 2 and Week 3.

Good Content but isnt't explained well. if you are motivated by yourself then go for it.

The is a lot of gap from what the lecturer learn and what the assignments requires.

Always spending much more time on coding than needed. Same result but no credit :(

The course content was good; however, it was not well explained at times.

I think content of first 2 weeks are disconnect with 3rd and 4th weeks

Math for the sake of math. Too big jumps in calculations, too complex.

its a good course to learn mathematics essential for machine learning
