Design a Visual Search Backend for a Boutique Luxury Marketplace

FreeVerified credential3 weeksAdvanced

Overview

What this challenge is about.

You receive a catalog of 80,000 luxury items (image + sparse metadata) and a labeled query set of 300 user photos with hand-picked target items. Choose an embedding strategy (CLIP, DINOv2, or a fine-tuned vision backbone) and build a vector index. Evaluate recall@12 and qualitative match quality. The backend must return results within 200 ms p95. Deliverable is the trained or selected embedding pipeline, the retrieval API, and a merchandising-team brief on quality limits.

The Brief

What you'll do, and what you'll demonstrate.

Ship a visual-search backend with recall@12 above 0.7 on the labeled query set and p95 latency under 200 ms.

Earning criteria — what you'll demonstrate

  • Select and evaluate vision embedding models for retrieval
  • Operate a vector index at catalog scale
  • Measure retrieval quality with recall@k and qualitative review
  • Communicate retrieval-quality limits to a non-technical merchandising audience
