Can you please elaborate a bit more on the model architecture and what you tried with respect to transfer learning?
Did you use an imagenet architecture e.g. VGG and retrain from scratch or a custom architecture? Did you try chop off the last 1/2/3 layers of a prerrained mode and fine-tune?
Bonus points: 1. How much better were your results trained from scratch vs fine-tuned? 2. How long did it take to train your model and on what hardware?
:)
We ended up with a custom architecture trained from scratch due to runtime constraints more so than accuracy reasons (the inference runs on phones, so we have to be efficient with CPU + memory), but that model also ended up being the most accurate model we could build in the time we had. (With more time/resources I have no doubt I could have achieved better accuracy with a heavier model!)
Training the final model took about 80 hours on a single Nvidia GTX 980 Ti (the best thing I could hook to my MacBook Pro at the time). That's for 240 epochs (150k images in an epoch) ran in 3 rate annealing phases, each phase being a handful of CLR (cyclical learning rate) phases.
I'll answer in more detail in the full blogpost, it's a bit complicated to explain in a comment. I'll have charts & figures for y'all :)
Thanks for sharing all the tech details too, it's been great to read. I'm even more amazed to see it as a real app, that I didn't expect!
Edit: Just read your bio. Now it makes sense!
Edit: I guess it's official: The time of XKCD 1425 has passed. https://xkcd.com/1425/ September 2014; Randall undershot that by a bit :)
EDIT: ah, it's in your profile ;)
Would you write a blog post about that journey?
search for "hot dog" or click on the hot dog icon:
In the early 90's, I had the honor of corresponding with "Uncle Frank" Webster [1], the curator of the Hot Dog Hall of Fame [2]! It boasts of more than 2,500 frankfurter items, including the Lamborweenie, a dog on wheels that "Uncle Frank" hopes some day to race against the Oscar Meyer Weinermobile [3]. Unfortunately the hot dog museum is currently closed and in (hopefully refrigerated) storage [4], otherwise the museum, gallery and gift shop would be a great place to train your app.
He asked for permission to publish in his newsletter a gif [5] of a photo I'd taken and put on my web site of the Doggie Diner head [6] on Sloat Boulevard in San Francisco [7]. (This was years before John Law acquired all the Doggie Diner heads he could find for his restoration project [8], so there weren't so many photos on them on the internet at the time.)
Of course I gave him permission because he asked so politely, and although at first he seemed a little creepy, I could tell he was authentic and sincere since he signed his correspondence: "With Relish, Uncle Frank." [9] And he even delivered on his promise to send me copies of his newsletter!
He enthusiastically informed me that the highest quality hot dogs he's ever found are from Top Dog in Berkeley [10]. He admitted that he went through their dumpster to find out where they sourced them from because they wouldn't tell him, and he vouches that they are made from the finest possible ingredients. I agree with Uncle Frank that Top Dog has really excellent hot dogs (ask for them cooked butterfly style), and I take him at his word that they come from a reputable source. You can now actually order them online [11] if you would prefer not to go through their dumpster.

The effort you put into the show is much appreciated.
I was REALLY depressed after watching these last two episodes. HungryBot was easily the coolest thing I've done in my unfunded nonprofit. But it was too buggy to fly. Kicked it out of the nest too early, but to the best of my knowledge it was the first deep learning food recognition app.
Looking for philanthropists if anyone wants to help me study diabetes with apps like this.
It's sad that this isn't more common outside of hot dog detectors.
It would be really interesting to read more about your thoughts on working with RN and C++ and perhaps how you did some of it. I'm currently doing the same (but with a C++ audio engine rather than image processing stuff) and I think it's an incredibly powerful combination - but I do feel like I'm making up some interop patterns as I go and there might be better ways, so would love to hear how other people use it!
Broadly, I've created a "repository" singleton that stores a reference to both the React Native module instance (which gets set when I call its setup method from JS) and the C++ main class instance (which gets set when it starts up), so they can get a handle on each other (I bet there are better ways to do this, but I'm new to C++/ObjC and couldn't work out a better way to get a reference to the RN module).
I'm then using RCT_EXPORT_METHOD to provide hooks for JS to call into C++ via an ObjC bridge (in an RCT_EXPORT_MODULE class), and using the event emitter to communicate back to JS (so the C++ can get the RN module instance from the singleton and call methods which emit events).
I've not done anything that really pushes the bridge performance to a point where I've seen any noticeable latency/slow down caused by the interop - have you had any issues here?
Like I say, I'm finding a really cool way to build apps that need the power of native code but still with the ease of RN as the GUI and some logic, and I actually quite like the separation it enforces with the communication boundary.

If the newspaper apps get to load fresh front page images, why should a poor neural net be discriminated in its quest for fresh coefficients?
(Raw oppression and injustice there, get yer indignation reservoir topped up.)
Video, I understand. From a consumer perspective it's crappy, but I do understand that licensing agreements for video are generally geographically restricted. But an app that goes along with a TV show? I can't see Sky (the UK network broadcasting Silicon Valley and most other HBO shows right now) distributing Not Hotdog.
It would be fun to play with it while the novelty is still fresh.
If not, I'm curious what the legal ramifications are of doing business as a corporation that does not exist.
Generally, the legal ramifications are a requirement to register the name and pay a small fee. In Santa Clara it costs $40 to register a fictitious business name with the county and the registration is good for five years: https://www.sccgov.org/sites/rec/Fictitious%20Business%20Nam...
It's really not a big deal.
Do I think SeeFood Technologies, Inc. is factually incorporated in a US state? No, I do not. I checked the four states it is most likely to be registered in (Delaware, California, Wyoming, and Nevada) and it isn't registered in any of them. Corporate registrations are a public record and trivially searchable; if I had access to Lexis-Nexis or similar I could probably run the search nationwide roughly as easily.
A sibling reply suggests that getting a Fictitious Name / DBA issued might be sufficient, but this would depend on the state/county/etc; some of them prevent folks from registering fictitious names with things which suggest actual corporations (like Inc.) or various things which the state wants to protect ("Bank", "Trust", "University", etc are common).
(DBAs are available like candy and might make a lot of sense if you've got e.g. an LLC which operates a product whose name is not the LLC's name, if for no other reason than "You'll possibly need this to convince your bank to let you deposit checks made out to $PRODUCT_NAME into $COMPANY, LLC's bank account.")

Congrats for getting the app out!
But seriously, the iTunes connect question specifically excludes stuff like HTTPS using the regular libraries, which is just as well as otherwise pretty much every app would be affected. Legal issue is probably boring IP rights stuff.
For an app like this I could easily see a serious company deciding to skip the hassle and CYA, instead of potentially taking on a huge legal risk. Would you, as a regular worker-bee developer, be OK with personally signing off and accepting a legal risk on behalf of a large company without involving expensive lawyers to evaluate the validity of your opinion on this legalese? Would that be a responsible action to take?
Is there any specific reason why this happens, just seems to me like you get worse reach and no benefits? Especially for a marketing stunt like this.
Maybe this comment thread could use a link to a video clip of the show.
Maybe this comment thread could use a link to a video clip of the app in use, since it doesn't work on most devices.
