This is great. Where are you hosting your caffe model? Just AWS with API Gateway?

#92Someone should combine this AI with something like Google glass (so you don't have to pull out your phone), a basic calorie/nutrition filter, and a shock bracelet[1]. That way when I look at a Krispy Kreme donut I get immediate feedback! [1]: http://pavlok.com/hello.php
google glass is dead though right ?

#93I would pay something like $5 per day for this if it was a real person who looks at my photos, categorizes them accurately, and enters them into MyFitnessPal. I won't trust an AI until it has a massive database and a million users. Until then, it's just not going to work well enough. You also need to convince users why they should use your app, instead of MyFitnessPal (which already has a massive database, including…
I have considered something like this as a business model, although I was thinking of nutrition coaching instead of mere logging itself, but thats actually a really great idea.

#94Pretty nifty, but please consider allowing creation of an account with a simple email address, or even anonymously. I really don't want to have to connect my Facebook or other social-networking information to your app in order to use it. Thanks for allowing one to try it out without logging in via another service; it'd be great to be able to actually have an account.
Email accounts are definitely on the long todo list.

#95Built using those newfangled convolutional neural network things. Trained caffe on a set of about a million food related images. Can't believe how accurate the classifier is... UI needs work. Would love feedback on how to make food logging more intuitive.
How much experience with machine learning did you have before you started this project?
Cut my teeth on the netflix prize several years back. Took ML in my graduate coursework, and have dabbled with it on and off since. I love the whole theory of matrix factorization and its myriad uses.

Its on the instance right now, but I could certainly post it to github at some point. I think I need to retrain it though and swap a few categories out. Theres a few animals in there ;)
Also, been needing to train on non-food items to weed out abuse.

BMI is a terrible metric - it's just a function of weight and height and a terrible indicator for health - most professional atheletes would have high BMIs due to a high muscle to fat ratio (muscle tissue being denser than fat tissue). It's not abnormal to be "overweight" - "obese" at 10% body fat depending on what sport you're doing. (long distance atheletes are normally quite lean, sprinters are bulkier)
It's really not a terrible indicator for health despite this argument getting trotted out every time the subject of BMI comes up on the internet. Obviously, as you pointed out, there's individuals for whom BMI is inaccurate but they represent a very small portion of the whole population. At a population level, it tracks very nicely with health outcomes. If you're a powerlifter or a sprinter, don't change your habits…
The metric is very convenient and a useful rule of thumb which is therefore perhaps useful for some proportion of the general population: especially for those with limited medical knowledge and/or equipment - but it's really not a niche minority who is unaccounted for by the BMI.
Muscle density and bone density, amongst other factors, will vary by ethnicity enough that researchers are discussing the value of one singular set of windows for the BMI[0], and although I don't have evidence I would also say that it really doesn't take much exercise for a person to skew their BMI by a noticeable amount - I would venture the top 30% of all exercisers would see their BMI affected by their habits.
So while there is value in the BMI for being easy to collect its data and make recommendations based on its value, in this day and age you'd really expect a more granular and precise measurement for use in research and disseminating health information.
It shouldn't be such a big leap for smartwatches / fitbits to measure body fat %, for example.

There's nothing stopping you from having a human aspect do the training and verification behind the scenes.
It's how companies such as Expensify were able to handle their receipt OCR gracefully for such a wide variety of invoices and receipts.
I'd err on the side of saying this is a more palpable sales approach to selling it as AI. Letting your customers know that while AI is running the show, things are being monitored closely and fixed by real people when misclassifications arise.

If you're eatting a lot of food with barcodes on it then your doing it wrong.
I don't understand this sentiment. My grocery store allows us to print barcodes that describe the weight and price of any produce or bulk order we purchase. This ranges from quinoa, oats, nuts, seeds, tea, along with the usual fruits and veggies. Also, don't bulk packages of vegetables tend to have barcodes on them inherently?

Ive been running the underlying nonprofit (infino.me) for about 3 years with this ambition to study gene-exercise-nutrition interactions, with very little interest in making any money at it. But this thought of having a paid service for people who don't want to go through the asspain of logging .... this does have me intrigued. Everyone tells me they want an effortless meal logging app ... and photo snaps might be the closest we can get short of having something like google glass persistently monitor intake.
