Summary
DataForGood is a French "association" that mobilizes tech to help citizen projects. We are part of season #10, this is our 4th season.
Main focus this year is on using machine learning to automatically categorize products so as to enable computing Nutri-Score and Éco-Score.
Description
Status: started
Expected outcomes: Have a new machine learning model, ready to deploy in production:
- That uses more features to predict category: OCR data, nutritional information, eventually images or any feature.
- Precision should be very high to be able to apply category automatically but the model should use its confidence to ask the user whenever needed.
Impact: massively increase the number of Eco-Scores and Nutri-Scores we are able to provide on the Open Food Facts platform.
Categorization is also important in many ways, for example to compare nutrition data with other products of same category (rank within a category).
Timeline:
- 2022-03-12: Data 4 Good kickoff event
- 2022-03-16: Actual project kickoff (first working session)
- 2022-06-12: Planned end of the project (Data 4 Good Demo Day)
