CycleGAN and Chef-RNN update

There has been a development in image generation that I find absolutely fascinating. It’s based off Generative Adversarial Networks, which are a very powerful and promising model for image generation. A recent modification to this architecture, the Conditional GAN has been making some waves, as it allows for the translation of one type of image to another, but it has the drawback of requiring databases of before and after images with roughly 1:1 correspondence, which is difficult to find, dramatically limiting the applications. However, very recently, the folks at UC Berkley made a few additional modifications which remove this requirement, creating the CycleGAN architecture. I’ve downloaded the source and been using the Flickr api to do some experiments with it, including trees <=> flowers, summer <=> fall, summer <=> winter, and landscape <=> desert. Legal disclaimer: I don’t own the rights to any of the images here. Unfortunately I neglected to get the photographers’ info when I scraped the images, but if anyone knows the creator of any of the original images please let me know. Here’s a few example images I’ve gotten so far:

Trees<=>flowers doesn’t work very well, which isn’t too surprising, but it is pretty entertaining sometimes what it does. It found pretty early on that it can do decently by just inverting the colors, but eventually the behavior got more complex and started making gross brown flowers:

summer<=>fall works just… absurdly well. It’s a bit scary, and some of the results are really pretty. With some parameter tuning and more (and better sanitized) data, this could be really cool! I’m definitely going to do some more experimentation with this.

summer<=>winter also works, though I couldn’t get it looking as good as the authors of the paper did. These examples are a bit cherry-picked, though– it never really learned how to fully get rid of snow, but it’s really good at color balance adjustments that make it feel way more wintery/summery.

The “desertifier” was largely unsuccessful. It never learned how to make things into sand like I’d hoped, but I didn’t train it for nearly as long as the others, and the success cases give me hope that it could learn:

Essentially what I’ve found is that the network doesn’t like to totally get rid of anything or hallucinate new things, even when it would make sense to do so. For example, if it gets rid of some water to make a desert, it might not be able to put it back- because of how the Cycle-GAN works, it needs to be able to reconstruct the original image. What it is really good at is changing colors and patterns, less good at structural stuff. I’d bet that you might be able to improve this behavior with skip connections between the initial transformation and the reconstruction pass. This would be similar to the “u-net” encoder-decoder architecture described, except the connections between the encoder and the decoder would also connect the first step of the titular cycle to the second. It might defeat the purpose a bit, but as long as there’s still an information bottleneck it might help.

Robo-Chef strikes again (barbecue sauce edition)

Finally, I discovered that I never did any experimentation with the sequence length I used to train my robo-chef, which would put a hard limit on how long it could remember things. Here are some recipies from a network trained with a much longer memory (3.5X longer)

That ain’t a soup! But look, it remembered the buttermilk! If you follow the instructions, you might end up with… some kind of cheesy corn-flake pastry? Weird.

That’s a lot of nuts! Also it forgot the cranberries. Once again, the instructions seem to be totally independent of the ingredients, but would make… some kind of cinnamon crumb pie? That actually sounds kind of delicious. I bet you could probably make something really tasty out of this one.

Wow! Not a bran muffin but this sounds… really coherent. This is one of the few times I think the instructions might result in a somewhat reasonable food.

BUT WAIT, are you ready for BARBECUE SAUCE?

title: crunchy barbecue sauce
categories: bbq sauces
yield: 1 servings

1/2 c brown sugar
1/4 c worcestershire sauce
2 tb brown sugar
1 tb cornstarch
1 tb water

1/2 ts salt
1 tb cornstarch
1 tb water
1 tb soy sauce
1 ts sesame oil
1 tb cornstarch
1 ts sugar
1 ts soy sauce
1 ts sesame oil

combine all ingredients except salt and pepper in a large saucepan.
bring to a boil, reduce heat and simmer for 1 hour. add cornstarch
and cook until thickened. stir in chicken and cook until thickened.
serve over rice.

And  here we go. Crunchy Barbecue Sauce. That full 1/4 cup of worcestershire sauce. The tons and tons of cornstarch. Oh. Man. What is going on? Weirdly enough, the instructions seem spot-on (except the last two sentences get a bit weird). Here’s a condensed list of the ingredients just to see if it makes sense:

2/3 c brown sugar
1/4 c worcestershire sauce
4 tb cornstarch
2 tb water
1/2 ts salt
2 tb soy sauce
2 ts sesame oil
1 ts sugar

The amounts might need adjusting, but at least it has the right flavors going on. I guess the amount of sugar is why it’s crunchy. But wait! There’s more! Barbecue sauces #1, #2, and #1 [sic]:

the chicken broth and cook for another 2 minutes. stir in the cornstarch
mixture and cook for 1 minute. stir in the chicken broth and cook,
stirring, until the sauce thickens. serve immediately.

Oh god this one made me laugh so hard. It’s so beautifully simple! I hope you like spices, because that’s what’s for dinner. Anyone know if this would make any sense at all as a spice mix?

So wait, what am I supposed to do with the chicken again?

Ok, now let’s really get cookin’!

It’s a what? I guess if you go to a Junk-Joint and order a Salet Burger this is what you get. Also those ingredients… substitute ground hamburger for spam and you might be able to make a decent, but weird, burger. What’s really neat is that the instructions remember that this is supposed to be pasta (which the ingredients conveniently forgot).

title: chicken & milk grits
categories: poultry
yield: 2 servings

1 whole chicken

1 tb olive oil
2 tb sour cream
salt and pepper
4 flour tortillas
cooked spaghetti
mushrooms
parsley
sauted mushrooms

combine flour, salt & pepper in a medium bowl. cut in margarine
until particles and can leave from tip. pat the mixture into a baking dish
and sprinkle with the cheese. bake, basting every 15 minutes, until
crust is golden brown, turning the cheese over after 35 minutes.
meanwhile, mix the egg and water in a small bowl. stir in the remaining
ingredients. pour grated cheese into the pie shell and bake for
20 minutes. remove from oven. sprinkle with roquefort on top.

What… what is this? The name is weird, the ingredients are… confusing (tortillas and spagetti?) and the instructions are for… some weird cheese pie. I don’t really know what to make of this. I think I may need to call a chef to reconcile some of these recipes for me. That said, if you did manage to actually make this it might not be half bad if you made some pretty liberal substitutions and improvisations.

But wait, are you ready to

with the salt, pepper and thyme. mix everything together gently and
add to the chicken mixture. cover and refrigerate for at least 4 hours

…and then what? Wait, do you serve this raw? It put SO MUCH WORK into those ingredients (look at all that vinegar) and then forgot to actually cook the meat (arguably the most important step).

Oh jeez too weird too weird. There’s so much going on in here. What is a dinworm? For that matter, What’s a lasagle? The first paragraph is 100% gold. Also, this recipe takes a long time. First, you have to stir some beans until pureed. You have to puree beans with a spoon. Then you cook the… dinnworm… for 15 minutes, then simmer the soup for 4-6 hours, then watch the “chiles” until they are “soupy, thoughly barbecued,” which takes 37 hours or up to 2 days.

3 md fresh mushrooms, thinly
sliced
1/4 c toasted sliced green onions
– (finely)
2 lg black pepper, the
1 tb grated parmesan or sandwich
1/4 c lowfat yogurt
1/3 c sour cream
lime wedges
parsley sprigs

1. place remaining ingredients in each of a bl. plate, cover and microwave
on 300of until cheese melts (about 15 seconds). serve at once, with
salsa.

Somehow the network made an OK sounding chip dip. I love that the instructions are basically “throw everything in a bowl and microwave.”

In summary, holy cow! This is so much more coherent than my previous experiments, and with only one night of training! I definitely need to dig into this a bit more. If you’ve somehow made it to the end of this post and want MORE, I’ve found another blog that does similar things. Check it out!

    Oh, gods above and below. “Soupy, thoroughly barbecued” may well describe my mental state after finishing this. I’m probably dehydrated from the tears I shed reading through this. I’m so glad I found this, I haven’t had a laugh like this in years. Perhaps I should drop everything and start a cooking show with this premise, can you imagine?
