Opiniones y comentarios de aprendices correspondientes a Big Data Analysis with Scala and Spark por parte de École Polytechnique Fédérale de Lausanne

If you know the subject, may be easy. If you don't know the subject, too dense and abstract with not enough practical examples/exercises before the assignments (specially for week4). Would have been better to break the videos into smaller ones, include more practical concrete examples/exercises during the videos (as very well done by Pr. Obersky during the 1st Course of the Specialization). There could have been room to break week4 into material for 2 weeks. Still, inresting.

Course is good to have some practice in spark and scala. However it seems to be long forsaken by staff and some issues with assignments require doing archaeology in the forums. Also it is quite unpleasant to see that while specialization emphasizes functional programming, some auxiliary code in assignments is written in the worst manner of imperative programming... Why use scala then?

Great Course content with amazing and challenging assignments!

Very nice, but a little bit outdated course

FANTASTIC!!! I don't even know which was better: the course material quality, the instructor's approach or the assignments. FANTASTIC!!!

A lot things to learn and experiment.

Challenging assignments.

Great course ! Thanks for the effort

Course is very useful to understand Spark and Scala things.

Great course over Spark. It shows the syntax, but more than this, it shows the problems, the caveats, the optimization and the architecture from a wide point of view.

The assignment were designed to focus right to the point: they managed all the configuration and initialization code of the project, leaving the student to fill only the most important part, with the resulto of having, at the end of the course, working projects that could be used as "cheat sheet" to remember all the material of the course.

Massimiliano.

Very good course for a great start in Spark. Require some initial knowledge and coding experience in Scala.

It was very challenging, but also informative. Thanks a lot.

Very useful course and great materials and assignments.

Thank you for the great introduction in to the Spark, What it is and What are the most commonly used APIs.

Excellent videos, explanation, and resources!

Favorite so far out of the Scala Specialization Course. It was executed really well, and taught really well, too. Kinda wish they would add more exercises to help us get more experience with some of the concepts, but that's something you can always just do by yourself either way.

It was amazing!!! Very useful course!

Perfectly. Very competent teacher and good tasks. Requires knowledge of scala.

Very good introduction which gets you to be productive on your own

Very informative. Well-organized presentation.

Amazing course!

Brilliant lecturer and slides! The only problem is assignments not being clear on the expected outputs. Sometimes it takes more time to figure out what exactly is asked than to find the solution. A few more test cases or detailed examples would help.

Nice session

good implementation of programming knowledge recieved

Muy bueno, Excelente. Todos los conocimientos obtenidos me serán de mucha ayuda en mi camino hacia el mundo de Big Data

Gives a good grounding in the fundamentals of Spark
