A very nice introduction to Apache Spark and it's environment. As a bonus, it's also a very nice refresher to your basic statistics!!! Great course!

A perfect course to pace off with exploration towards sensor-data analytics using Apache Spark and python libraries.\n\nKudos man.

I find it unacceptable that the grader still had the same old problems from months ago. Adding notes directly to the python notebooks is not that difficult. #Return 4 significant digits, etc.
Plus, the grader output is not always useful. I execute the function in the python notebook, for whatever reason it does not fail, it works. The grader is more sensitive as it should be but it would be more meaningful at least it mentioned which line it has failed or which cell or which function.
The quizes during the videos seems a bit too random. I expect, if you are interrupting a video, you would be asking a question whose answer would be relevant for the later part of the video. Those pop-ups feels like unannounced midterm exams. There is already a full quiz section for this.
Perhaps my expectations were too high for this course.

Course content contains too much screen capture of clicking rapidly through IBM could menus. In most cases, the version of IBM Cloud now being deployed varies from the course, so students have to figure it out themselves.
Also, explanation of the tools and resources is very short - line one sentence. We are left to figure out what the tools are - cloudant and node-RED especially.
This course and certificate look like they should come after the first Data Science Certificate (9 courses). But there is a definite gap between the two. It is not clear what course is supposed to bridge that gap.

This course needs work. There needs to be more of a challenge, being an advanced course I expect a certain level of difficulty. I think the knowledge is too high level. There also needs to be more of a hands on approach. Let me connect to the Cloudent service, and more practice using spark and map functions.

Simply not on the same level as other ML Courses on Coursera. Programming assignments don't require you to do much by yourself. The bits you have to write, you have to guess from function names (no task description or anything is given).

Very good course but codes and instructions are outdated. It needs serious improvement on that part. It is costing a lot more time to finish this simple course.

The instruction is not so clear. Many mistake launch and grader does not run to score your submission.

While the course info describes this course as a beginner level, I would not describe it so. A lot of technical terms are thrown around without even saying a word about them let alone explain them.
The course is very disorganized, and the instructions for the assignments are not correct (and outdated). You have to basically figure out on your own how to set up the system before you even start doing the actual assignments. What you actually experience is completely different from what you see in the screenshots of the instructions.
This has been my experience just after being 2 weeks into the course. Hopefully things get better in the last two weeks. Honestly, so far I have only learnt a bunch of names.
I will update my review at the end of the course, if needed.
UPDATE: I eventually decided to unenroll from this course. This course is not worth it, in my opinion.

Corrupted assignment, you will never pass assignment 2 as the assignment checker was corrupted. so disappointed. in fact nice lecture and tutor and videos.

This course takes you on a very structured path. It starts with the core concepts of spark and how is it important in the industry. The material along with the IBM cloud platform is a total bonus.
The assignments are challenging for a reason. They test your entire knowledge and makes sure that you pay careful attention to the material being delivered. In fact, while completing the assignments, you will find yourself looking through official library documentation for support; this is a good thing. Moreover, you also find yourself writing good quality code.
Romeo teaches the content in the simplest way possible. He explains the concepts with utmost care with adequate examples. The content on statistics is also very well laid out which helps you become a better decision maker.
Overall, the course was excellent and should suffice for anyone willing to learn spark and get familiarity with cloud technologies and Apache Spark.

Strong introduction into parallel computing and big data processing. Romeo's expertise on the subject matter, combined with his love for teaching was on show during this course. He did a great job explaining the theoretical aspects, and slowly but surely introducing us into the practical aspects as well, through the programming exercises. All in all, this has proved to be a high quality introduction into this space and I'm excited to take the next step, learn more and apply the fundamentals I have picked up here.

A really good introduction to Apache Spark. The course has been changed around a lot to conform with the latest syntax and to make it easier to get to work with data. Many of the videos still refer to the old syntax but the examples have all been brought up to date. Students no longer need to generate their own data (with node-Red) but can immediately get to work on pre-generated data. All this change has made some parts of the course a little confusing, but a little perseverance will overcome these problems.

Nice introduction, not too difficult without being so easy that you learn nothing.
Sometimes outdated contents, but I always find solutions quickly to make everything work. In fact it is better to have realistic examples and to use up-to-date technologies, even it is of course harder to maintain. Therefore my remark is not a complaint. Actually Mr Kienzler does a good job to keep things working and the learners informed.

Be careful when signing up for your IBM Cloud Instance and remember to shut it down when you're not using it. I ran out of free hours and unfortunately they're no longer free after the first 30 days which either makes it impossible or expensive to finish this course. Also, 30 days might mean an arbitrary 30 day billing cycle, perhaps starting on the 1st of the month.
