Fascinating course! The lecturer gives very detailed illustrations to many complicate concepts. It will be much better if the submitting systems work fine for the last assignment.

Course content is interesting and well planned, Can be improved by making it Simpler for Students as it was more technical than the other 2 courses of the Specialization.

it's very fantastic course.i enjoyed a lot.i feel reading material should be increases in those courses,others things are perfectly ok.thanks for offering this courses.

Course content tackles a difficult topic well. Only flaw is that programming assignments are poorly designed in some places and are quite difficult to pick up at times.

The course is generally good but the assignment setting definitely needs to be rectified. Thanks anyway for this course. An important element of machine learning.

Teaching pacing is good, and clear in explanation. It will be good if there are some examples about how we should apply all these theories to some real problems.

Overall the course was great. The only thing was that there was a lot I didn't understand from the videos. The recommended textbook resource was a great help.

The other two courses were much more didactic. And there were some bugs in these courses assignments... But, overall, it was a great course on the subject

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.

The explanation of the model is very precise but there are unnecesary comments for PCA omit the comments related with std in the final assignment

A different course than the previous 2.

Much harder - as you have to actually know some Python tricks.

But I guess it's the same in a real world.

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.

The final Notebook contains some errors (Xbar instead of X, passed as an argument). Otherwise a very well organized course. Thanks a lot!

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

Jupyter notebook assignments are in desperate need of attention! Very buggy or non-intuitive for the scope of material in span of time.

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

The lecture & instructor are great. But the grader in the assignments really needs revisions. It caused lots of unnecessary stress

Please change courese material for PCA. It is very un-understandable and assignments are also very tugh as per what is taught.

Focus a bit more on PCA in week 4, week 1 was not very informative and should be assumed as required knowledge for the course

Careful, step-by-step construction of the PCA algorithm with practical exercises and coding assignments.. Very well done...

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.

The first two courses, are really good but the third one is slightly off the track, with many glichtes and more.
