Great course that covers some of the fundamentals of advanced data analytics. I use some of these techniques (like PCA) in my career for discovering defects in devices. This is a great starting course.

Concise course. Has its challenging aspects, but overall was clear. The best part is the programming assignment and tutorials: great hands-on introduction to IBM Watson Studio with manageable examples.

Nicely arranged course. However, both assignment on week 4 should be rechecked to make sure that it could run as exercise to student. Also, please make sure that the video is up to date and less error.

Very useful courses to take if you are beginner of data science. The course was not detailed enough sometime. But you will surely get a global view of IOT data analysis after this courses.

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!

Its a great experience especially with this course. I appreciate Romeo the way he designed the assignments. It brings out the clear understanding.

It feels really good when you get to learn something new and Coursera helped me to achieve something and learn something new and good.

I really like this learning method from IBM especially the instant quiz just to make sure I understand the important points.

This is one of the best course I came across so far, please keep on updating and adding such courses, Thank You
