Opiniones y comentarios de aprendices correspondientes a Fundamentals of Scalable Data Science por parte de IBM

Great

This was not especially well made. A number of the examples shown on videos don't necessarily work or are outdated with respect to the platform or the datasets you're working with. Perhaps, greater attention should be given towards guiding the student to the github repo were the notebooks are up to date and working properly. Otherwise a good course, definitely not introductory to cloud, if that's what you're looking for. There is some high level programming that I'm defnitely not prepared for but the notebooks are so complete that I did not have to apply myself so much. So on the one side I appreciate the ease of the notebooks but, on the other side, have some doubt as to the practical knowledge acquired. Hoping later courses in the specialization clear this out for me.

It was difficult to follow the IBM cloud setup since it was constantly changing, I couldn't understand the reason for using python2.7 since its only 10 months before it wont be supported by the community. Sometime instructors' pronunciations were not clear and and thus added extra confusion. However, instructor do actively participate in helping with discussions. Audio and video quality were also not very good. This course is a very basic introduction to IBM cloud and general stats. Prior knowledge of spark is useful. Overall the course is nice introduction to IBM cloud if one is interested.

This is a good introduction and overview to working with Spark. The assignments are very straightforward and I think that the biggest benefit is learning how to set up a work-station in IBM and working with your notebooks there. One thing that I think should be improved is the version of Python and Spark that is being demonstrated: the lectures should update to Python 3 and we also have Spark 3 by now; focus should be on data frames instead of RDD. Also, lots of links need to be updated because their references are deprecated and so no longer exist.

This is a very basic course even if it's my first interaction with Apache Spark. For sure, it gives some information. But I found the timeframes stated too long. You feel like you'll get a lot of information. But a week of videos and readings and assignments can be done in 1.5-4 hours depending on your experience how much time you spend on assignments.

Also, there are many materials that are outdated. That should be fixed if this course carries the name of IBM.

The coding part is easy to comprehend but the course does not offer much opportunity to practice and learn the coding. The assignments are straight forward and doable. Sometimes it is hard to read the code in the videos even at 720p as it appears blurred. The subtitles cover some of the formulae shown at the bottom of the video and there are many mistakes in subtitles.

Overall, it is a good introductory course that gives you an idea of about Apache Spark.

Good

The Course touches the important topics related to scalable data. The quizzes & assignments were challenging and the fun to solve.

Bad

Though the course touches the important topics, it does not go deep into it. Some of the codes provided in the video didn't work with the current version of python and spark. For example the code for finding the median. The Cognitive IOT app development method provided was broken and it wasn't the right way to do it.

I was really looking forward to this specialization but from the very first course I am really disappointed. The videos refer to various not updated information and then suddenly we are expected to do an assignment that was not at all explained in the course. I am not saying it is difficult, or not achievable but to be honest until now (week 2) it feels mostly like a waste of time.. Really sorry for this review.

The course should be updated. It's hard work, but it's worthy. I'm sure students get confused a lot with the inconsistencies generated by the update of IBM Watson. So, there is some minus difference nowadays with what's being taught. Anyways, I think the content of the course is perfect to start. I learned satisfactory tools and ideas about how to handle big data.

The idea and material behind the course is really interesting, albeit very basic. Some of the exercises and quizes, like the ones of interpreting plots are not very clear, since the plot quality is low. However, this is a very nice introduction to ML and IoT using Watson. Looking Forward for the next courses of the IBM Degree for advance data science

I​n my opinion, the slides for this course should include more graphics. Especially showing the relations between different tools and objects. As an example, the Video "Introduction to Cloudant" would profit a lot if some graphics showing the relations between it and Apache Spark would have been used instead of simply going over bullet points.

The course is called 'Fundamentals' and is indeed pretty basic. A good quick overview of the most basic concepts. Sometimes too basic to qualify for an Advanced course on Coursera. So, not really clear for which audience the course is.

Another fundamental course that does a better job is Spark Fundamentals from cognitiveclass.ai.

Very very basic. Far away from advance. I did more than the whole course in just one lecture at my university (LSE). And that lecture at the university did not assume that we already got experience with Spark or python. I still give three stars because it is still quite ok, just far away from advanced.

Good material. Hard to understand the instructor's English. No professionally presented. Assignments are too easy, and we didn't get good, meaningful practice. Quizzes often address information that either the instructor failed to present well, if at all, or made mistakes on.

I felt that, for a course labelled as 'Advanced', there were too many trivial questions in the quizzes and too much hand-holding in the programming assignments. That being said I did enjoy the course and learned quite a lot and look forward to the next one in the specialisation.

The course was great, the material and the assignments.

IBM Watson platform was easy to use.

But I can't see how this course is included in the "advanced" data science specialization.

Honestly I was expecting a more advanced course. But we'll see with the next ones.

The content was OK, but I have expected more. Probably it was too basic for me. I would have been happy to see some more real life examples, like when to use the different statistics to solve real problems, not only the theoretical ones.

A detailed explanation on the trade off of different approaches that can be used in Big Data but there is not enough examples of manipulating big datasets

I believe that the assignments of this course should have been a bit more rigorous. Also, there should have a been a bit more focus on Apache Spark.

The course content is amazing but the instructor's accent is very difficult to understand and in some videos subtitles in English weren't available.

give lot of details about pyspark like basics.

its getting hectic with just the small details given in videos.

videos needs to be changed and updated

Good introductory course, however it would be better if the assignments were more involved rather than having the code typed out already for us.

Some of the content in the video should have been updated due to the change of interface. Had some difficulty setting up the environment.

Topics can be taught a bit more slowly, it was a bit difficult for me to understand. Otherwise, the content covered was very helpful!

The content was okay, but it is pretty basic. There is legacy from previous versions of the course that needs better transitions
