Frequently Asked Questions
What is rare event and edge-case annotation?
It involves labeling low-frequency, high-impact behaviors and anomalies, such as emergency responses, equipment interference, unusual movements, extreme lighting, and unpredictable interactions, so AI models can perform reliably in real-world, high-risk situations.
What types of rare events can DDD annotate?
We capture emergencies, panic reactions, medical distress, falls, sudden posture changes, PPE-related occlusions, rapid movements, object interference, seatbelt misuse, environmental disruptions, and surprising multi-occupant interactions.
Why are edge cases important for in-cabin AI models?
Most AI failures occur during rare events, not during normal behavior. Training models on these long-tail scenarios dramatically improves safety, reduces false positives and false negatives, and ensures readiness for real-world deployment.
Can DDD build custom taxonomies for anomalies and safety-critical scenarios?
Yes. We co-design detailed classification frameworks for emergency behaviors, environmental extremes, unexpected human actions, and anomaly severity levels tailored to your model architecture.
