A portrait "painted" by an AI was sold for $432,500 at Christie's Auction House. The algorithm behind that art was developed and trained by a Paris based art collective, who listed an estimated selling price of "7000 - 10000 Euros" at the time of this writing. The artists tried feeding the AI a number of different genres, including nudes and landscapes, but they found that "portraits provided the best way to illustrate our point, which is that algorithms are able to emulate creativity." 'The algorithm is composed of two parts,' says Caselles-Dupre. 'On one side is the Generator, on the other the Discriminator. We fed the system with a data set of 15,000 portraits painted between the 14th century to the 20th. The Generator makes a new image based on the set, then the Discriminator tries to spot the difference between a human-made image and one created by the Generator. The aim is to fool the Discriminator into thinking that the new images are real-life portraits. Then we have a result."
