IBM via Coursera

Overview

Do you want to know why Data Science has been labelled as the sexiest profession of the 21st century? After taking this course you will be able to answer this question, and get a thorough understanding of what is Data Science, what data scientists do, and learn about career paths in the field.

The art of uncovering the insights and trends in data has been around since ancient times. The ancient Egyptians used census data to increase efficiency in tax collection and they accurately predicted the flooding of the Nile river every year. Since then, people using data to derive insights and predict outcomes have carved out a unique and distinct field for the work they do. This field is data science.

In today's world, we use Data Science to find patterns in data, and make meaningful, data driven conclusions and predictions.

This course is for everyone, and teaches concepts like Machine Learning, Deep Learning, and Neural Networks and how companies apply data science in business.

You will meet several data scientists, who will share their insights and experiences in Data Science. By taking this introductory course, you will begin your journey into the thriving field that is Data Science!

    Started this through Coursera and then realized I could take it for free (exact same class) through CognitiveClass.ai.

    Basic information which required no studying, just watching videos and remembering what was presented.

    I preferred the CognitiveClass.ai version as it came with an IBM badge and certification, plus I could read the transcripts quickly and move to the next section without having to watch the entire video.

    Either way it was a simple course that I completed in maybe 90 minutes with a score of 100%.
  • Berbelek completed this course, spending 5 hours a week on it and found the course difficulty to be easy.

    Very short introduction to data science. No tools and techniques so far, no statistical or programming background. Just the idea and roots of data science explained. The videos and some point of views are quite interesting, but I'd not call it precisely a course, because there are no knowledge or skills to be learned here.

    This course gives a decent overview about data science.

    I personally liked the personal stories of the professor at University of Toronto.
