What is generative adversarial network (GAN) — and how it makes computers creative

This article is part of Demystifying AI, a series of posts that (try) to disambiguate the jargon and myths surrounding AI. Moments of epiphany tend to come in the unlikeliest of circumstances. For Ian Goodfellow, PhD in machine learning, it came while discussing artificial intelligence with friends at a Montreal pub one late night in 2014. What came out of that fateful meeting was “generative adversarial network” or (GAN), an innovation that AI experts have described as the “coolest idea in deep learning in the last 20 years.” Goodfellow’s friends were discussing how to use AI to create photos that looked…
