Too much confusion, I face too much problem with this course. much confusion if you use different packages like sklearn.

The course content seemed to be rushed out, as a result, the quality is not as good as the first two.

Why don't you guys talk about ID3 or CART algorithm at all? This one is too basic.

Exercises for Scikit-learn users were not organised.

Course took too long to start

Nice course but I would have expected more techniques (SVM for instance)

Theory Quizes are good, but programming assignment not so good for me.

more topics like deep learning, neural networks need to be introduced

Good, but overemphasizes niche software product (graphlab).

The exercises/assignments are far too simple

too simple

good

.

I leave 2 stars as I learned a lot of new information and methods, and the theory and math behind them.

You will learn about Data Science and Machine Learning, but not much about Python.

The course is pretty much abandoned and outdated. Sframes and Turicreate packages (instructor's creations) are used instead of more universal packages. Installation in the beginning took some time and research. Many of the assignments have errors and bugs in the code that have not been updated. Forum assistance is abysmal for clarification or deeper questions. Many links are dead.

There are many times in the lectures where the instructors are writing several sentences in their handwriting on their notes instead of having the text ready to appear.

I would suggest using this course and series as a supplement to other information one as learned, not as an introduction for initial understanding. I found myself frustrated too many times.

The video content is awesome. Important concepts are being clarified in a very simple manner. However the evaluation method really sucks. First, there is too much spoon feeding in the programming assignments, which was not the case in earlier courses in the same specialisation. Secondly, in a few assignments, the answer to the quiz questions are sensitive to the platform we are using (like PC vs AWS instance). This was really frustrating given that the issue is known for a long time and has not been fixed yet. At the very least, there should be a warning on the quiz page itself.

The assignments are well thought out and explain the algorithms step-by-step. The subtitles/transcripts are a disappointment :( . Full of mistakes. Sometimes to the point of being useless or even worse - saying the exact of opposite of what the lecturer says. Since the lecturer sometimes is unclear - this is problematic. As usual - Graphlab Create sometimes crashes, however there are explanations how to run the assignments using Scikit-Learn.

The content seems rather thinner than that of earlier courses in the specialization, and seems to get more so as the course progresses. (Week 6 is entirely spent on Precision and Recall, with only about 30 min of lecture.) It feels like there was a rush to get the course out and that corners may have been cut at the end.

And as others have mentioned, several very important classification topics are conspicuously missing.

Overall good explanations in the videos; however, too much reliance on GraphLab, so that it seems more like promotional course for the instructor's own software and company. Also, the course is generally a bit light on content - the only algorithms discussed are Logistic Regression, Decision Trees and AdaBoost. Spending a full week on precision & recall is way too much time.

This course needs to be re-created using new professors.

Way too lazy IMO.

Too many "trick questions", total confusion between Python 2.x and 3.x

Too theoretical, almost no practical examples

Quizes are very poor and give no "hints" or true workhtrough examples pror to test.

This is a problem with all Coursera, though.

I am afraid that this course is, to a large extend, a marketing tool for promoting the instructors' proprietary product. Its use is therefore limited for the practitioners that want a foundation on the free Python data/ML capabilities.

I would not recommend this course to my colleagues.

Not as polished/comprehensive as the previous courses (especially week1, week5 and week6). But useful techniques nevertheless.

The speaker is very difficult to understand, and the environment for writing code is awful (web browser).

Extremely highlevel, quality of the material is significantly lower than in the previous courses.

Course is too slow to keep focus, it's repetitive but not clear when it's really needed.

The classes are not practical, and the voice of the teacher is very monotone, boring.
