AI Can Create a Music Playlist That Changes with Your Mood

The project started as the brainchild of Elad Liebman, a Ph.D. student in computer science who also has a degree in music composition. The program that he, Saar-Tsechansky, and Peter Stone, a professor of computer science, designed runs a series of feedback loops. It tries out a song, the listener rates it, and the program heeds that rating in choosing the next song. "Then you alter the model accordingly," says Liebman. The program adapts to the listener's mood, considering not only which songs he or she will enjoy, but also in what order.
