Questions & Answers

Q: How did the team verify the quality of the data during the design phase?

The team closely examined the data and identified areas that needed cleaning or preparation. They also determined the minimum number of labels/categories required for training data.

Q: What challenges did the team face in categorizing text messages related to maternal health?

Categorizing the content of messages, such as identifying if they were related to maternal health or another problem, posed difficulties. Classification accuracy varied across languages based on the available data.

Q: How did the team address performance trade-offs between complex and simpler models?

After investigating various models, they found that a simpler and more reliable model was the right choice for this use case. The simpler model allowed for faster retraining, ensuring near real-time feedback for clinic staff.

Q: How did the team assess the impact of AI on the existing manual solution?

The team compared the volume of response and response time of the AI solution with the purely manual solution. They aimed to improve response time and increase message processing while maintaining a similar overall quality of response.

Summary & Key Takeaways

  • During the design phase, the team focused on verifying data quality and preparing it for the AI solution.

  • They determined the minimum number of labels/categories needed in the training data and evaluated the difficulty of automatically processing certain categories.

  • The team designed an annotation strategy for additional training data and explored performance trade-offs between complex and simpler models.
