Translate Pictures of Food into Recipes with Deep Learning

For ML practitioners, how much more/less difficult is this than predicting calorie content/macros from pictures/video of food? Because that seems like the holy grail of “calorie counting” apps, to seamlessly track (within a small margin of error) what your macros for the day are so far, thus helping you make intelligent choices about what to eat & portion size. Especially since those apps are great for sticking to diets, if it weren’t for all the mind-numbing data entry.

Hotdog or not hotdog

This seems to use only one image of each recipe (unless I'm misreading the code).

That seems to be a pretty big flaw.

It's sad to see people waste time on such pursuits. Getting a recipe is very easy. Just google it. Or even reverse image search it.

I do get that these exercises add a lot of know how to the deep learning process, but I really wish these smarts are applied to more practical and immediate problems.
