Hello? Is it me you're looking for? Improving Spotify Search with Jonny Brooks-Bartlett

When a Spotify user types a query into the search bar it sets off a cascade of algorithms which ultimately ends in the user being shown a set of music and/or podcast results.

This cascade of processes can be very complex as we must try to understand exactly what the user is looking for and choose a handful of results from a set of 10s of millions of potential options. As more and more items are added to the Spotify catalogue, from music to podcasts and soon audiobooks too, the Search team has increased in size and scope to try to tackle the growing challenges. In this talk Jonny gives an overview of the components of a typical search system and explains some of the challenges that arise in search systems.

Then, he talks about some of the new algorithms that Spotify has developed over the last year that have led to huge improvements in Search quality. Finally, he outlines some of the general lessons that he's personally learned (but in super speed) with building machine learning models.

ℹ️Jonny currently works as a Senior Machine Learning Engineer at Spotify working on improving the search functionality on the app.

Prior to this he was a data scientist at Deliveroo working in several different areas including personalised restaurant recommendations on the consumer app, menu classification and fraud detection. Before that, Jonny also worked as a data scientist at News UK where he was responsible for building machine learning models to aid editors with the creation and promotion of news articles.

Outside of his work as an engineer Jonny has recently become a father to a beautiful little girl and spends most of his free time trying to figure out how to be a good daddy. He also tries to juggle this with a love of high intensity fitness challenges.

Jonny previously played American football for 9 years, and now is a keen functional fitness competitor. Jonny has a Master’s of Mathematics degree from the University of Southampton and a DPhil from the University of Oxford in mathematical x-ray crystallography.
