Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might have been a recent change in the annotation process. Has there been any update to the annotation guidelines or tools in the past month?

Why it matters: Changes in processes can directly impact accuracy rates. Expected answer: Yes, there was a minor update to the annotation tool UI. Impact on approach: If confirmed, we'd focus on the tool update as a primary factor.

• Considering the scale of the drop, I'm wondering about the dataset composition. Has there been any significant change in the types of images being annotated recently?

Why it matters: Different image types may require different annotation approaches. Expected answer: There's been an increase in complex, multi-object images. Impact on approach: We'd need to assess if the current annotation process is suitable for these new image types.

• Given the specificity of the 15% drop, I'm curious about our measurement methodology. Has there been any change in how we measure or calculate accuracy rates?

Why it matters: Ensures we're comparing apples to apples in our metrics. Expected answer: No changes in measurement methodology. Impact on approach: If confirmed, we can rule out measurement issues and focus on actual performance factors.

• Thinking about external factors, I'm wondering if there have been any changes in our annotation team composition or training programs?

Why it matters: Team changes or training gaps could lead to inconsistent annotation quality. Expected answer: There's been a 20% increase in new annotators over the past two months. Impact on approach: We'd need to investigate the onboarding and training processes for new annotators.
