- Exploring the obesogenity of community food environment: This project will develop a deep learning model to identify the nutritional information of local restaurants through food images shared on social media. The derived information (e.g., food calories, cost) will be employed for making dietary recommendations on multiple platforms, eventually helping to increase the nutritional awareness of those vulnerable to obesogenic foods in urban areas.
