Video Action Recognition for a Retail Loss-Prevention Startup

FreeVerified credential3 weeksExpert

Overview

What this challenge is about.

Use a public action-recognition dataset (UCF101 + a small curated retail-action subset; the latter is provided synthetic or you can label 50 short clips). Fine-tune a small backbone (X3D-S or VideoMAE-tiny). Evaluate top-1 accuracy + a strict FP budget (under 1 FP per 1,000 customer-minutes) at recall above 75 percent. Deliver model + evaluation + a 4-page memo addressed jointly to product and legal.

The Brief

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

Train an action-recognition model that achieves at least 75 percent recall on suspicious actions while staying under 1 FP per 1,000 customer-minutes.

Earning criteria — what you'll demonstrate

  • Fine-tune a video action-recognition model on a domain-extended dataset
  • Evaluate under a hard FP budget tied to product cost
  • Diagnose action-confusion failure modes
  • Communicate model boundaries to legal + product stakeholders
