Heh, a few years ago I thought of this same thing. I didn't know anything about ML so I thought it'd be possible by doing the following (for food served in a restaurant/fast-food) 1. Tag the location (if you go to McDonalds and take a picture of a Big Mac you'll see that you're at McDonalds and you have a picture). 2. Then, to get your "nutrition" info you have to manually specify what you're eating. 3. What you're eating would then be matched to a database that would provide the nutrition information. The picture basically would be there just to show you what you ate. --- This looks WAY better than that.
