(Don't) Play It Again: Recommendation Engines from Data to Prediction

One evening, one dataset, one idea: if the algorithm knows what you've listened to, can it guess what you want to hear next?

Play It Again is a hands-on workshop where we build a music recommendation engine from scratch. We'll start with raw Spotify track data, clean and shape it together, then wire up a model that actually makes predictions. You follow along, you build, you leave with something that runs.

You'll be in the code the whole time, working with real data on a problem worth solving. Expect to build.

What we'll build

♫ Data prep: Pulling apart the Spotify dataset, understanding what's in it and getting it into a shape a model can use.

🤖 Recommendation engine: Training a model on listening patterns and turning it into something that suggests what to play next.

📊 Results you can see: Exploring the dataset visually with charts so you understand what you're working with. Then seeing the model's actual output as a ranked list of track recommendations you can read and reason about.

How the night runs

Doors open at 6PM.

Kickoff at 6:30 PM with a short intro, then we get into it.

Two parts, one flow. Data first, predictions second.

Food and drinks included.

Bring a laptop. We'll work in Google Colab, so no setup needed ahead of time.

Come to learn, come to build, come to see your playlist in a completely different light.
