Twilight star among three authors of paper explaining how ‘neural style transfer’ method was put to use in her directorial debut, the 17-minute short Come Swim 
 
 Twilight and Personal Shopper Kristen Stewart has co-authored a research paper on “neural style transfer”, an arcane technique that uses artificial intelligence to reconfigure an image in the style of another. To do this, you basically show your algorithm an image (say a painting by van Gogh) and then teach it to apply the same painting technique to any regular photo. Called Bringing Impressionism to Life with Neural Style Transfer in Come Swim, the paper was submitted on Wednesday on Cornell University library’s open-access arXiv.org website, an online repository for scientific research papers. Written with Bhautik J Joshi, a research engineer at Adobe, and producer David Shapiro, Stewart’s paper is related to work done on her short film directing debut Come Swim, which received its world premiere at the Sundance film festival on Thursday.
– If she ever abandons acting, Kristen Stewart might have a gig in artificial intelligence. The Twilight actress has just published a research paper on a machine learning technique called "neural style transfer" and its use in film, reports Quartz. Style transfer is a "fun technique," according to Tech Crunch, though it's a bit complicated to explain. Essentially, an algorithm is used to apply the style of one thing to something else. In this case, Stewart—with help from Starlight Studios producer David Shapiro and Adobe research engineer Bhautik J Joshi—sought to transfer the look of one of her own paintings to scenes from her short film Come Swim. Using computer programs known as neural networks, the group was able to add "blocks of color and texture" to a test frame until it matched the look of the painting, which depicts "a man rousing from sleep," reports the Verge. Once they had achieved the look they wanted on the test frame, they applied the same technique to the opening and closing scenes of Come Swim, described as "a poetic, impressionistic portrait of a heartbroken man underwater," which premiered at the Sundance Film Festival on Thursday, per the Guardian. The Verge notes you might have used this same technique yourself: Facebook introduced a style transfer filter last year.
