"Powering Spotify's Audio Personalization Platform" by Josh Baer (Strange Loop 2022)
Over 400 million people in 183 markets open their Spotify app at least once a month to see a brand new set of recommendations from a pool of 85+ million songs and podcasts. Those recommendations on the home page, in your playlist creation screen, from your search bar, and in your Discover Weekly are driven from Machine Learning models powered by a complex set of tools working in unison with the sole purpose of building a more intelligent Spotify product.
In this talk, Josh Baer – product lead for Spotify's Machine Learning Platform – will walk you through the lifecycle of a song recommendation and the complex software that orchestrates the various backend, data and ML specialized libraries built to make the lives of Spotify engineers easier. He'll describe the challenges of creating a Platform that trains hundreds of models daily and serves millions of predictions per second for 50+ teams building ML for Spotify, and discuss why there are so many companies building similar tooling.
