Model Diffusion of a Hashtag Across a Music-Discovery Platform
Overview
What this challenge is about.
Model hashtag diffusion on a music platform, identify top seed accounts, and quantify organic adoption with a bootstrap. Earn your verifiable certificate.
The scenario
The platform (Series C, around 250 staff, freemium + label-licensing revenue) currently spends about USD 1.2M per quarter on influencer marketing with weak attribution; the growth team needs a defensible model before reallocating.
The Brief
What you'll do, and what you'll demonstrate.
Attribute a hashtag-adoption spike between organic diffusion and seeded influencer activity, with quantified uncertainty.
Earning criteria — what you'll demonstrate
- Fit an information-diffusion model on a real social graph
- Distinguish seeded from organic adoption with quantified uncertainty
- Run a bootstrap to surface attribution stability
- Communicate causal-attribution caveats honestly to a budget owner
