I have just completed a Wolfram-U-Course in Multiparadigm Data Science. Very useful for people that want to gain more insights in Data Science with Mathematica.
Is such a course also interesting to you? Here is the link https://www.wolfram.com/wolfram-u/multiparadigm-data-science/
Multiparadigm Data Science is a rapidly advancing new approach of using modern analytical techniques, automated machine learning and human-data interfaces to arrive at better answers.
