The enigmatic, painted smile of the “Mona Lisa” is known around the world, but that famous face recently displayed a startling new range of expressions, courtesy of artificial intelligence.

Researchers trained the algorithm to understand facial features’ general shapes and how they behave relative to each other, and applied that information to still images.

It was created by Egor Zakharov, an engineer with the Skolkovo Institute of Science and Technology, and the Samsung AI Center (both located in Moscow).
