1. Which explanation matches write an annotation guide?A. An annotation guide defines categories, boundaries, edge cases, and examples before labeling starts.B. Splitting by camera, time, and scene prevents near-duplicate context from making the test too easy.C. Evaluate errors by relevant conditions and groups, along with counts and uncertainty.D. Domain shift changes geometry, colors, resolution, or background from the training data.

3. Which explanation matches evaluate by conditions and subgroups?A. An annotation guide defines categories, boundaries, edge cases, and examples before labeling starts.B. Splitting by camera, time, and scene prevents near-duplicate context from making the test too easy.C. Evaluate errors by relevant conditions and groups, along with counts and uncertainty.D. Domain shift changes geometry, colors, resolution, or background from the training data.

4. For split by camera, time, and scene, which result or action fits this practical case: Frames from the same camera appear in both training and test sets.A. Document how to mark partially visible cars and vehicles in the driving lane.B. Hold out a later week or a new camera when that is the deployment question.C. Report occupancy accuracy separately for daylight, rain, and low light.D. Test held-out images from the new camera before reusing old regions and thresholds.

5. For test a new camera domain, which result or action fits this practical case: A new camera has a different angle and sensor.A. Test held-out images from the new camera before reusing old regions and thresholds.B. Document how to mark partially visible cars and vehicles in the driving lane.C. Hold out a later week or a new camera when that is the deployment question.D. Report occupancy accuracy separately for daylight, rain, and low light.
