Grocery Recommendation with Collaborative Filtering

Basket-aware product suggestions trained on Instacart order history

3-4 weeks build

Overview

Built on the public Instacart Market Basket Analysis dataset, this kit recommends groceries two ways: association rules mined with FP-Growth for items bought together, and implicit-feedback matrix factorisation for items a shopper is likely to reorder. A FastAPI service backs a React basket page that updates suggestions as items are added.

What makes it stand up

  • 01FP-Growth association rules with support, confidence and lift
  • 02Implicit-feedback ALS for personalised reorder suggestions
  • 03Recall@k and MAP@k measured on held-out orders
  • 04Popularity baseline included for honest comparison
  • 05Live basket page that re-ranks suggestions as you shop
