About the Course

Apache Spark is the de-facto standard for large scale data processing. This is the first course of a series of courses towards the IBM Advanced Data Science Specialization. We strongly believe that is is crucial for success to start learning a scalable data science platform since memory and CPU constraints are to most limiting factors when it comes to building advanced machine learning models. In this course we teach you the fundamentals of Apache Spark using python and pyspark. We'll introduce Apache Spark in the first two weeks and learn how to apply it to compute basic exploratory and data pre-processing tasks in the last two weeks. Through this exercise you'll also be introduced to the most fundamental statistical measures and data visualization technologies. This gives you enough knowledge to take over the role of a data engineer in any modern environment. But it gives you also the basis for advancing your career towards data science. Please have a look at the full specialization curriculum: If you choose to take this course and earn the Coursera course certificate, you will also earn an IBM digital badge. To find out more about IBM digital badges follow the link After completing this course, you will be able to: • Describe how basic statistical measures, are used to reveal patterns within the data • Recognize data characteristics, patterns, trends, deviations or inconsistencies, and potential outliers. • Identify useful techniques for working with big data such as dimension reduction and feature selection methods • Use advanced tools and charting libraries to: o improve efficiency of analysis of big-data with partitioning and parallel analysis o Visualize the data in an number of 2D and 3D formats (Box Plot, Run Chart, Scatter Plot, Pareto Chart, and Multidimensional Scaling) For successful completion of the course, the following prerequisites are recommended: • Basic programming skills in python • Basic math • Basic SQL (you can get it easily from if needed) In order to complete this course, the following technologies will be used: (These technologies are introduced in the course as necessary so no previous knowledge is required.) • Jupyter notebooks (brought to you by IBM Watson Studio for free) • ApacheSpark (brought to you by IBM Watson Studio for free) • Python We've been reported that some of the material in this course is too advanced. So in case you feel the same, please have a look at the following materials first before starting this course, we've been reported that this really helps. Of course, you can give this course a try first and then in case you need, take the following courses / materials. It's free... This course takes four weeks, 4-6h per week...

Nice course. Learned the basics of a lot of different topics. Nice to do a large Data Science project in the last part. So you can apply all learned theory

Great Course but this would have been even a better course if more concepts and details were covered in it. Anyways, still a great course for beginners

Gives you a great understanding about the fundamentals and how apache spark works. However, some exercises and files are outdated and it will not take you the amount of time the course info indicate, fow me it was less than half of it

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

The functions we need to complete looks quite messy, it'a little bit overwhelming especially for people who start with spark.

I felt the course is out of date and have worked on these classes to update it so that I can run the video classes again

the assignment is required to be in sparkaql functions however the course is just using spark with built in functions

Too many legacy issues. Would be better to start a new course altogether and maintain same syntax,etc.

By George H

Analytically very simple, and fails to explain much of the syntax needed for the assignments.

The videos have not been updated to fix the errors (there is just a hint for a correct code)

Very basic lessons. Definitely what you would expect from an Advanced course.

More coding please. One doent learn much just by filling out couple words

Too many theory for such little practice. But not bad as an intro.

A little more deep tutorials on spark language would be useful
