DataForGood-2022

Summary

DataForGood is an association that mobilize 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 use 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 it's confidence to ask for user when needed

Impact: augment massively the number of Eco-Score and Nutri-Score we are able to provide on the platform.

Categorization is also important in many way, for example to compare nutrition data with other products of same category (rank among category).

Timeline:

• 2022-03-12 launch at Data for good launch event
• 2022-03-16 project kickoff (first working session)
• 2022-06-12 theoretical end of the project
