Mine Association Rules for a Grocery Retailer's Promo Strategy
Overview
What this challenge is about.
You'll mine 22M grocery baskets, filter rules by lift, and cluster promo bundles for a buying team. Earn a verifiable certificate.
The scenario
The grocery chain (around 8,000 staff, around EUR 2.1 billion annual revenue) refreshes its flyer weekly; a 2% average-basket-size lift is worth around EUR 40 million per year.
The Brief
What you'll do, and what you'll demonstrate.
Mine 6 months of basket data to surface 10 promo bundles with quantified expected basket-size lift.
Earning criteria — what you'll demonstrate
- Apply Apriori or FP-Growth at retail scale
- Set support/confidence/lift thresholds defensibly
- Cluster many small rules into a small set of buying-team-actionable bundles
- Project expected lift with explicit assumptions
