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.
Kinda complicated but doable. The stuff do not monitor the discussion forums unfortunately. Without Susan's detailed & well informative replies I won't be able to complete the course. Big THANK YOU to Susan.

The course is interesting, but some of the quizzes were not done very well. After the first 2 parts of this course, which were just amazing, this one seems kind of worse, although by itself its not that bad.

Difficult course. They need more formal tutorials to help with the gap between the videos and the tests and projects. I found it very helpful to buy the instructor's textbook and read along in it.

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!!!
By Nicholas K•
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.
By Dominique D•
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.
By Wang Z•
The knowledge introduced in this course is really helpful. However, the programming assignments are very time consuming and not necessarily relevent
By Iurii S•
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.
this is a great course except the assignment has quite a few bugs and the videos are too short and lack many topics, and the quiz are too short

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).
By D. H•
The system is problematic, just take a look those complains in the forum. I also got very frustrated from the last assignment.
By NEHAL J•
The course was highly challenging. I wish some of the explanations were detailed and the assignments had better instructions.
By Ana P A•
The professor of other two a way better. This one skips some steps in some explanation that makes the tasks hard to do
By Chuwei L•
worse than previous courses of machine learning specialization. Really confused me when introduced the inner products.
By SYED H•
The course needs to introduce more advanced technique and practical examples or create a new Advanced course on this
Honestly this course is the one worthing attempting. However, last week's content is really messy and challenging.
By Hsueh-han W•
many steps are not clear enough that I have to spend a lot of additional time to figure out the details.
By Saurabh M•
This course is pretty hard. The most important pre-requisite for this course is persistence.
By Gurudu S R•
Tutor is not clear and concise on the concepts. Need more examples for Week 2 and Week 3.
By Vishesh K•
Good Content but isnt't explained well. if you are motivated by yourself then go for it.
By Sagun P S•
Tough one if you are new to programming or doesn't have excellent understanding of Maths
By Keng C C•
explanations are not clear, need to refer to lots of youtube to catch up with course.
