This AI Can Spot Art Forgeries by Looking at One Brushstroke - MIT Technology Review - Pocket

The most promising part of the research might be the way the researchers used the second method to make clear what the RNN is doing, says Eric Postma at Tilburg University in the Netherlands, who has done work in detecting art forgeries with AI for more than a decade. There could be more applications for artificial intelligence in art, he says, but art historians and researchers, steeped in centuries of tradition, have been slow to embrace such techniques. That's in part because it can be difficult to understand how a machine arrived at its results--a problem this latest research could help solve.
