π How Does Spotify Know You So Well?
To create Discover Weekly, there are three main types of recommendation models that Spotify employs:
- Collaborative Filtering models (i.e. the ones that Last.fm originally used), which analyze both your behavior and othersβ behaviors.
- Natural Language Processing (NLP) models, which analyze text.
- Audio models, which analyze the raw audio tracks themselves.
