Pandora Radio

  • Owns Music Genome Project

○ Used for song recommendations

slide-5
SLIDE 5

Music Genome Project

  • Songs are described by ~400 "genes"

○ ex: West coast rap roots, Cool jazz qualities ○ Each gene assigned value (1-5)

slide-6
SLIDE 6

Music Genome Project

  • Each song is represented as a vector
  • Song similarity is calculated using distance

functions

slide-7
SLIDE 7

Music Genome Project

  • The "nearest" song vectors to the source

song are recommended

slide-8
SLIDE 8

Music Genome Project

  • Weights are applied to important genes to

improve results

slide-9
SLIDE 9

Music Genome Project

  • Matching multiple source songs

○ Center vector is calculated and used as the source ○ Inverse standard deviations are used as weights
