Pandora Radio ● Internet radio service ● Personalized stations ● Considers user feedback

Pandora Radio

Pandora Radio ● Owns Music Genome Project ○ Used for song recommendations

Music Genome Project ● Songs are described by ~400 "genes" ○ ex: West coast rap roots, Cool jazz qualities ○ Each gene assigned value (1-5)

Music Genome Project ● Each song is represented as a vector ● Song similarity is calculated using distance functions

Music Genome Project ● The "nearest" song vectors to the source song are recommended

Music Genome Project ● Weights are applied to important genes to improve results

Music Genome Project ● Matching multiple source songs ○ Center vector is calculated and used as the source ○ Inverse standard deviations are used as weights
