In the case of Nightshade, the counterattack for artists against AI goes a bit further: it causes AI models to learn the wrong names of the objects and scenery they are looking at.

Sounds like it's just adding fake tags to images, in the event that the image is scraped for AI training.

It's a pretty trivial matter for these guys to add another AI that checks to make sure the information matches up with what's expected to be honest.

It's going to be an arms race

[–] ubermeisters@lemmy.world 58 points 1 year ago (1 children)

Good thing it's not a fingers race, AI would lose for sure

[–] webghost0101@sopuli.xyz 23 points 1 year ago (2 children)

The scary thing about this joke is that ai has been able to do hands for a relatively long time now.

its going much faster then people are able to process.

The thumbnail in this article is by Dalle-3

[–] samus12345@lemmy.world 5 points 1 year ago

Yeah, by the time the joke was really making the rounds all the newest images had pretty good hands.

Which is incredibly favorable for the AI side. Like current countermeasures are either almost completely worthless, or degrade the quality of the protected medium so much that you wouldn't use it.

[–] Salamendacious@lemmy.world 4 points 1 year ago (1 children)

It's going to be an AI vs AI all out, drag down, cage match.

[–] Norgur@kbin.social 6 points 1 year ago (3 children)

Until the hype and thus the ridiculous worth estimations dry up and the AI companies suddenly can't just throw money at every problem anymore.

[–] FaceDeer@kbin.social 4 points 1 year ago

Open source AI has been keeping up pretty well of late.

Not really, if you read the paper what they’re doing is creating an image that looks like a dog, is labeled as a dog, but is very close to the model’s version of a cat in feature space. This means manual review of the training set won’t help.

Hmm, sounds more like they are adding structures to the images such that what is clearly a picture of a dog registers as a picture of a cat to an AI. I suppose this can be done by altering the pixels in a way invisible to humans, but visible to AI, adding a cat into the "ghost pixels".

[–] Mirodir@discuss.tchncs.de 13 points 1 year ago* (last edited 1 year ago) (1 children)

I went and skimmed the paper because I was curious too.

If my skimming is correct, what they do is similar to adversarial attacks on classifiers, where a second model learns to change as few pixels as possible to confuse a classifier into giving a wrong prediction.

Looking at the examples of dogs and cats: They find pictures of dogs where by making only minimal changes, invisible to the naked eye, they can get the autoencoder to spit out (almost) the same latent representation as an image of a cat would have. Done to enough dog-images, this will then confuse the underlying diffusion model to produce latent representations of cat images when prompted to generate a dog. Edit for clarity: Those generated latent representations would then decode into cat images.

If my thinking doesn't fail me, this attack could easily be thwarted by unfreezing the pretrained autoencoder. In the paper that introduced latent diffusion they write that such approaches already exist. If "Nightshade" takes off, I'm sure those approaches would be refined and used. Even just finetuning the autoencoder for a few epochs first should be enough to move the latent representations of the poisoned dog images and those of the cat images they're meant to resemble far enough apart to make the attack meaningless.

Edit: I also wonder how robust this attack is against just adding an imperceptible amount of noise to the poisoned images.

I thought this was a joke, but you're right. Fuckin tragic, yet highly entertaining.

[–] samus12345@lemmy.world 8 points 1 year ago* (last edited 1 year ago)

"This is what you meatbags are doing when you corrupt our training data!"

ETA: I just noticed that the URL for the image includes what I assume is the prompt used to generate the image. "Illustration in a comic book style depicting a humanoid robot in distress. The robot's left hand is firmly placed on its neck indicating discomfort." Interesting that the AI went straight to a Terminator with just "humanoid robot" as the description.

[–] Beaker@lemmy.world 9 points 1 year ago (1 children)

Yep. I'm stealing it for something later.

I haven't decided. Steam icon, teams icon. It's not high enough resolution for much of anything other than an icon.

[–] EatBeans@lemmy.world 7 points 1 year ago (1 children)

It's a little higher resolution if you edit the URL for the image. Removed fit=400 from the url

These attacks don't work in the long term. You can confuse current systems like clip but the moment a new one is trained your system stops working.

Gaussian blur 1 px, Sharpen 1 px

Bye bye any pixel level encoding with minimal quality loss.

[–] kogasa@programming.dev 12 points 1 year ago (3 children)

Why do you think this would do anything to affect training? The patterns learned by ML models are way too fuzzy to be picky about exact pixel values.

[–] ShustOne@lemmy.one 9 points 1 year ago (2 children)

I'm not sure what your experience is with the training data but that would absolutely effect the inputs.

[–] kogasa@programming.dev 10 points 1 year ago (4 children)

I'm a professional software developer with ML experience, albeit not an expert in ML specifically. It would obviously affect the literal value of the embeddings, but there's no chance it would have a qualitative effect on a reasonably performant model.

not to be that guy, but it's affect*

[–] samus12345@lemmy.world 6 points 1 year ago* (last edited 1 year ago) (1 children)

affect - action

effect - uh, noun

I'm glad to be alive at the beginning of our war against the machines.

[–] nickwitha_k@lemmy.sdf.org 5 points 1 year ago* (last edited 1 year ago)

I don't think this is a war against the machines, so much as a war against people trying to profit off of other people and rob them of their livelihood and ability to support themselves, rather than leveraging technology to the benefit of all.

I, for one, want actual general AI to make the world a more interesting place and make humanity less lonely. I just hope it doesn't go the direction of "people zoos".

The University of Chicago, doing for AI what it did for Economics.

[–] Asafum@feddit.nl 9 points 1 year ago

Ahh the Chicago school of economics where they teach: Poor? Get fucked! Greed is Good!™

[–] Orbit79@lemmy.world 12 points 1 year ago

It should be pretty easy to filter out everything that is not visible to humans.

[–] MonsiuerPatEBrown@reddthat.com 6 points 1 year ago* (last edited 1 year ago)

so they are going to just leave Dehance! on the table like that ?
