Learning Data Science and Machine Learning: First Steps - KDnuggets

At the start of this year, I published a mind map on the Data Science learning roadmap (shown below). The roadmap was widely accepted, that article got translated into different languages, and a large number of folks thanked me for publishing it. Everything was good until a few aspirants pointed out that there are too many resources and many of them are expensive. Python programming was the only branch that had a number of really good courses, but it ends right there for beginners. Answers to a lot of these questions can be found in the book Deep Learning by Ian Goodfellow and Yoshua Bengio.But that book is a bit too technical and math-heavy for many.
