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!

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 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 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.

Tough one if you are new to programming or doesn't have excellent understanding of Maths

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.

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

If you like traditional lectures, which you go into a math class then feel puzzled, then go for it. Otherwise, the contents of this course are simply going through the mathematics equations and definitions, which can easily be found in textbooks. Ironically, the previous two courses in this specialization used lots of graphics and animations to help you understand the maths (either in terms of equation-wise or intuitively), this course completely lacks this element.
