Stay on target MIT’s AI Knitting System Designs, Creates Woven GarmentsResearchers Train AI To Feel Emotion, Too In humans, short-term memory allows unrehearsed recall for a period of several seconds to a minute. In neural networks, it introduces hilarious effects.In her latest AI experiment, research scientist Janelle Shane adjusted the length of her computer’s memory, making it “really, really short.”Therefore, when the network looks back over generated content, it sees only a couple of words at a time, instead of full phrases.“Here’s how this plays out when I train a neural network to write lyrics to Disney songs,” Shane teased in a blog post.Starting with a list of 224 tunes (about 8,200 lines), the system displayed a “modest” memory length of 50 letters, which looks a little something like this:“ow you the worldShining, shimmering, splendidTel”Children of the ’90s will instantly recognize those choppy sentences as the opening lyrics of “A Whole New World,” the beautiful ballad sung on high (from a magic carpet) in Aladdin.And just like you’re now singing along with Jasmine and her prince, the neural network can memorize whole lines of songs. Though, with a degree of randomness built into the system, it doesn’t always land on the right chord.“A whole new world (A whole new world)A new fantastic point of viewNo one to tell us noOr where we will live”I personally like the rebellious twist on Tim Rice’s lyrics.The song continues, launching into a repetitive chorus of “let it snow” (the original tune written in 1945, and recorded for Disney’s Phineas and Ferb Holiday Favorites album), before eventually settling into a Pocahontas theme:“With the colors of the windCan you paint with all the colors of the windCan you paint with all the colors of the windCan you paint with all the colors of the windCan you paint with all the colors of the windCan you paint with all the colors of the wi”Repeating lines in the original dataset (as Pocahontas does as she and John Smith frolic through the forest) creates a broken-record effect: the neural network simply learns that one line is followed by the same line.“What it doesn’t know, however, is how many ‘colors of the wind’ lines it’s already seen at a given point,” Shane explained.With limited hindsight, the network doesn’t know whether to move on to the next line, or keep singing the same one.“Usually, like Dory, it just keeps singing,” she said.With each trim of characters—from 50 to 20 to 10 to five—the network’s functionality begins to dwindle.Sign up online to relive your childhood and get more bastardized versions of Disney songs from Shane’s neural network.
