Do you get down to Jackson Five, or is Stravinsky more your style? Artificial intelligence (AI) that predicts taste in music might seem stranger than fiction, but researchers at Jönköping University in Sweden and Maastricht University in the Netherlands believe they've cracked the code. In a paper published on the preprint server Arxiv.org, the team described a system that considers a person's listening behaviors and, using machine learning algorithms and psychological models, infers their "musical sophistication." "Psychological models are increasingly being used to explain … behavioral traces," the team wrote. "The use of domain dependent psychological models allows for more fine-grained identification of behaviors [like music listening] and provide a deeper understanding behind the occurrence of those behaviors."
