Apple has a new feature in iTunes which is an instant playlist. Elliot Feldman of the Associate Press explains, "Genius is a feature of iTunes 8 that creates instant playlists from the music that's in your iTunes Library. Just select a song to play from your iTunes Library, click on the Genius button (an atomic symbol) on the bottom row of the iTunes 8 browser interface, and an instant playlist of songs is generated from your iTunes Library. Along with the instant playlist generated from your iTunes Library, Genius also generates a sidebar list of compatible songs that you can purchase from the online iTunes Store."
Now how does this work? I was told that they cross-reference data from everyone's playlists so if a lot of people like Madona and they also like Britney Spears then iTune's uses this data to make the Genius playlist. A verision of Bayesian statistics at work here? Now this might be the cheaper and only way data about restaurants can be gathered because unlike songs, restaurants constantly change. So is a "restaurant genome project" not possible? Just something to think about here.
