Concept-Activation Vectors for an Autonomous-Vehicle Perception Audit
Overview
What this challenge is about.
You receive a trained semantic-segmentation model (8 classes including pedestrian, vehicle, road, sky), an internal validation set of 2,500 driving frames, and a small concept-image library (around 150 examples each across 6 concepts: 'wet road', 'bright sky', 'sticker on vehicle', 'snow on road', 'shadow', 'glare'). Implement TCAV to compute concept sensitivity scores per class and per image-batch. Identify the top-3 concept-class pairs of concern, characterize them on the validation set, and write a 3-page red-team memo with recommended dataset/training mitigations.
The Brief
What you'll do, and what you'll demonstrate.
Audit a production perception model for spurious-concept reliance via TCAV and recommend dataset/training mitigations.
Earning criteria — what you'll demonstrate
- Implement TCAV for a real segmentation model
