Great course!\n\nEmily and Carlos teach this class in a very interest way. They try to let student understand machine learning by some case study. That worked well on me. I like this course very much.
Very good overview of ML. The GraphLab api wasn't that bad, and also it was very wise of the instructors to allow the use of other ML packages. Overall i enjoyed it very much and also leaned very much

I did not have a lot of experience in machine learning, so this course was very good in the aspect of introducing people to machine learning concepts. Most of the times the material was very well explained, and I like the concept of the tutor writing on the screen at the same time they are presenting, personally it helps me more. Some of the quizzes were easy so you did not need a lot of preparation, some of them were more difficult or troublesome, like the quiz for Deep Learning. I also liked the graphlab module, I think that learning how to use it will help me with my own work.
However, as this course does not really go in depth in the algorithms themselves, I feel that after one month and a half I have a basic idea, but I haven't learned much about how to implement machine learning on my own even in basic things, while other courses have more or less the same time frame and are more dense in their material. In my opinion, this whole introductory course would just be just splitted and each of these intrductory weeks would be appended as the first week of the subsequent modules to come. Because anyways, after 4 months in the specialization, if somebody continues to the recommender systems module for example, he/she would have forgotten the basics of this so they would need to cover again the recommender systems week in this course. And from the other hand, if some introduction is again repeated in the subsequent modules, then why have this introductory course anyways?

The biggest downside of the course is that instead of learning on open source machine learning modules (sklearn) the course offers Dato's GraphLab, a proprietary piece of software that requires paid licenses to operate.
To be clear, during the duration of the course students can use a student license that provides graphlab for free but this expires after a year. It seems like fine software but if you arent going to purchase a license after the class expires whats the point? Also, Graphlab is built on top of python2.7. If you are running python 3.0+ on your machine youll have to install a python 2.7 instance.
Otherwise the quality is solid. The philosophical approach the professors take is to give you a taste of a variety of machine learning models. The upside is that if you want to get a taste you can. The downside the course feels pretty shallow and then the next course in the specialization -- regression -- feels like a pretty stark contrast. In general it could be argued that this is a problem with all coursera courses. How do you modulate course difficulty when you could be targeting students who are somewhere between high school kids to computer scientists? So the course and the specialization tilts between very easy and very hard.

The course is effectively a tutorial on how to use proprietary software to solve a range of machine learning problems.
I liked the fact that the course covered a wide range of problems quickly. There were however two issues that I did not like.
1) It is not well supported and given that the technology is proprietary, there are few other places that offer support (i.e. you can’t just look at problems and solutions on stackoverflow to get insight into the tech)
2) For a course labelled as “intermediate”, it presented very little detail. Most of the course was dedicated to explaining particular problems, the solution to which was inevitably “then you train this really clever, one-line algorithm we have written for you and you query it for insights”. I felt a little cheated by this approach to a subject which should be really fascinating.
While some of my concerns may be addressed in follow on courses, I am left with little insight into what really lies ahead. For example, is this really an “intermediate” course? What background do I really need? Will we ever get to the detail or will I always just be expected to call someone else’s brilliant algorithm and accept the result.
