Now i feel confident about pursuing machine learning courses in the future as I have learned most of the mathematics which will be helpful in building the base for machine learning, data science.
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 is way more brutal than the two previous courses in the specializationIt is also very mathematically oriented, it lacks the graphics / animation / intuition that was given in the first two courses.However, if you make it, you indeed have a good understanding of PCA.

A lot of input in relatively short time, main points could be pointed out better in the videos. Assignments were tough but manageable, the instructions could be clearer and more detailed. However, being pushed to figure out things by yourself is also a learning opportunity.

To me, the first 3 weeks in this course is good. But the 4th week is quite confusing. And I don't understand the applicable meaning for the materials in the 4th week. I may need to review what I learned in the 4th week and then decide whether I understand it completely.

Instructor has good knowledge of the subject. The course content structure is designed well.
Concepts could have been presented with more clarity. Programming assignments need more instructions and less assumption on what the students already know.

Quality of the course is great, but I would question whether it belongs in this specialization given the huge jump in expected knowledge from the first two courses to this one. Relied alot on the forums and YouTube to gain sufficient knowledge to complete this course.

Instructor has done lot of hard work. However, the course is little rigorous. If it is possible, I request the team to upload few more videos for this module. Nevertheless, thank you so much. I have still learned a lot from this course.

The content is decent but there are some bugs in the programming assignments. Particularly the last two programming assignments. The auto-grader for the second to the last assignment passes in some input that is not of the correct form.

The course content was very good,but the assignments were harder as knowledge of python libraries was required. It would be very helpful if you change the assignments as I feel the course should rather be about math than python
Positive points: At the end of the module, you get a good understanding on how PCA works. It fulfill its objective.
Negative points: The assignements are poorly directed, the material is not always clearly explained.

Good Course, but
Too less examples to do the quizes on the first run.
Programming assignments are not clearly stated, so you need unnecessary much time to succeed.
I liked the Linear Algebra & Multivariate Modul more!

The course is Satisfactory.The content is Good,no doubt about it,but many topics(both mathematical and computational) were unknown and coding assignments of Jupyter notebooks of this course(PCA) are very Buggy
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.

I was expecting this course to connect with the previous two but it turned out to be self contained. Jupyter notebooks contain inconsistent comments and assignment steps. Certain tasks were not clear.

The jump in difficulty for the final two modules was too hard going from the previous two courses in my opinion. also I would have liked more practical examples rather than being directed to reading.

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!!!
автор: 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.
Instructor made a good attempt to cover these complex topic. However, these topics should be supported with more examples and also provide more intuitive examples as in previous 2 courses.

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.

Difficult course even having completed the two courses that precede it. Some concepts introduced here as assumed knowledge that were not covered in the prior courses.

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
Thank for the excellent course content but i think it would be nice if teacher could do more example or apply than just math formula introduction
