Visual introduction to bias in machine learning

A few years ago, Stephanie Yee and Tony Chu explained the introductory facets of machine learning. The piece stood out because it was such a good use of the scrollytelling format. Yee and Chu just published a follow-up that goes into more detail about bias, intentional or not. It’s equally worth your time. (Seems to work best in Chrome.) Tags: machine learning, scrollytelling

Digital revolution in China: two visual takes

Ancient Earth globe shows where you were located 750 million years ago

In a spin on the view of ancient Earth and the shift of the continents, Ian Webster made a globe where you can enter a location and see what was in that spot millions of years ago.
