    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.

          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.

        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.

          Do you think an authentic AGI would have ethical\moral boundaries completely divorced from what the original software programmed? In other words would it be able to make it's own decisions without interference?

              I hope they will because I feel like if AGIs have ethical decision-making skills that Terminator-esque dystopian future becomes remote. If they never have that then we very well might be at the mercy of the world's largest conglomerations.

      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.

        What are the implications for the non-ai viewer? I have tonassume that these changes aren't perceptible to humans but I find that to be a stretch also. I don't see artists willing to have an AI manipulate thier art, so that AI can't recreate it.

          I don’t think the idea is to protect specific images, it’s to create enough of these poisoned images that training your model on random free images you pull off the internet becomes risky.

      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".

        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.
