recommended for all the 21st centuary students who might be intrested to play with data in future or some kind of work related to make predictions systemically must have good knowledge of this course
Issues of every stage of the construction of learning machine model, as well as issues with several different machine learning methods are well and in fine yet very understandable detail explained.

Instructor rushes the course and does not explain much in the same level of details as respective quiz requires

All the formulas and code in slides are too abstract. If can be more charts to interpret that will be better.
创建者 Henrique C A•
Exercises could be more complete, and some are outdated for latest R, giving slightly different results.

A fine introduction, but there are much more engaging and better quality courses out there...

If you have taken Andrew Ng's machine learning class, it's not necessary to take this one.

I think it was a very fast course and I feel more real examples would have been useful,

Poor supporting material in a course that tries to cover a lot in a very limited time.
创建者 Rafael S•
this course seemed too rushed for me, too little content for such a extense subject
创建者 Raj V J•
more needs to be taught in class. what is taught is not sufficient for quizzes.
创建者 Surjya P•
Overally course is good. But weekly programming assignments will be great.
Too different for beginners but not deep enough for ones already know R.
创建者 James F•
Quizzes are useful exercises but need to do a lot of self studying.
创建者 Philip A•
mentorship was great, but the video lectures were almost useless.
创建者 Christoph G•
The topic is too big, for one course from my point of view.
创建者 Foo C B•
Much of the material and instructions need to be updated.
创建者 Ariel S G•
In my opinion, this course needs a few extra exercises.
创建者 Jorge L•
Fair but assignments are not very well explained
创建者 Bahaa A•
Good enough to open up mind of researcher

I need study more this course

I really enjoyed the content of the course. I already knew a fair amount about machine learning but I learned a lot more than I thought I would. Most contents of weeks 3 and 4 - decision trees and random forests, bagging and boosting, linear discriminant analysis and naive Bayes, forecasting and unsupervised predictions - were my favourite topics in this course.
The biggest disappointment in this course for me were the outdated quizzes. I worked really hard through this course and most of the Data Science specialisation. But the quizzes are set up for older versions of R and some of its packages, so the results are completely different from what I got most of the time. I found this extremely frustrating and disheartening and had to repeat the quizzes several times. I do realise that most quizzes enumerate at the beginning the versions they are using, but there is no mention of how one goes about to set that up in R. On top of that, given that I rarely passed the quiz on the first try my Skill Tracking score dropped considerably, undermining weeks and weeks of hard work.
Unfortunately, this tainted my view of this course and I would advise the course organisers to update it as soon as possible.

Had big expectations for this one... really one of the ones to look forward to after working through the beginning of the specialization, but for some reason, it seemed any prof or even TA interaction was absent this time around like in none of the other specialization coursed to date. Bugs in the new interface and quizzes weren't really addressed. Couldn't even get an official response about the apparent removal of Distinction-level now (which I'd been working to get in all specialization courses and now seems no longer an option). Still interesting content. As a "free" course, it's still really valuable. As one of the people that paid for this and all others in this specialization, this is the one I felt didn't return as much value to justify the payment with no "official" course staff seeming to be involved this round.

I was disappointed with this course. For better or worse ML is a part of data science and, in this course, the instructional depth was lacking. The lectures provided examples of how to implement a few ML algorithms in R, with very little actual instruction on the intricacies of these algorithms, theoretical foundations etc. Taking the course I felt somewhat cheated (a google search would have done the job of the class), and frustrated with various little bugs in Quiz/Assignment content.
