Collaborative Filtering

Collaborative Filtering, short CF, is the most commonly used recommendation system for streaming services. In the case of Spotify, users cannot “like” or give a rating to songs, therefore, the algorithm uses other information to search for similar tastes between users, which is the ***stream count of songs*** and additional information, e.g. how songs are placed in users’ playlists and how often artist pages get visited. Furthermore, Spotify creates a unique vec- tor for every single user and song and recommends based on the similarity of these vectors.
