A judge in Washington state has blocked video evidence that’s been “AI-enhanced” from being submitted in a triple murder trial. And that’s a good thing, given the fact that too many people seem to think applying an AI filter can give them access to secret visual data.

How is guided pattern recognition is different from imagination (and therefore intelligence) though?

There's a lot of other layers in brains that's missing in machine learning. These models don't form world models and ~~some~~don't have an understanding of facts and have no means of ensuring consistency, to start with.

They absolutely do contain a model of the universe which their answers must conform to. When an LLM hallucinates, it is creating a new answer which fits its internal model.

Statistical associations is not equivalent to a world model, especially because they're neither deterministic nor even tries to prevent giving up conflicting answers. It models only use of language

[–] lightstream@lemmy.ml 1 points 7 months ago (1 children)

It models only use of language

This phrase, so casually deployed, is doing some seriously heavy lifting. Lanuage is by no means a trivial thing for a computer to meaningfully interpret, and the fact that LLMs do it so well is way more impressive than a casual observer might think.

If you look at earlier procedural attempts to interpret language programmatically, you will see that time and again, the developers get stopped in their tracks because in order to understand a sentence, you need to understand the universe - or at the least a particular corner of it. For example, given the sentence "The stolen painting was found by a tree", you need to know what a tree is in order to interpret this correctly.

You can't really use language *unless* you have a model of the universe.

But it doesn't model the actual universe, it models rumor mills

Today's LLM is the versificator machine of 1984. It cares not for truth, it cares for distracting you

They are remarkably useful. Of course there are dangers relating to how they are used, but sticking your head in the sand and pretending they are useless accomplishes nothing.

[–] Natanael@slrpnk.net 1 points 7 months ago

They are more useful for quick templates than problem solving

I mean if we consider just the reconstruction process used in digital photos it feels like current ai models are already very accurate and won't be improved by much even if we made them closer to real "intelligence".

The point is that reconstruction itself can't reliably produce missing details, not that a "properly intelligent" mind will be any better at it than current ai.

Your comment is a good reason why these tools have no place in the courtroom: The things you describe as imagination.

They're image generation tools that will generate a new, unrelated image that happens to look similar to the source image. They don't reconstruct anything and they have no understanding of what the image contains. All they know is which color the pixels in the output might probably have given the pixels in the input.

It's no different from giving a description of a scene to an author, asking them to come up with any event that might have happened in such a location and then trying to use the resulting short story to convict someone.

They don't reconstruct anything and they have no understanding of what the image contains.

With enough training they, in fact, will have some understanding. But that still leaves us with that "enhance meme" problem aka the limited resolution of the original data. There are no means to discover what exactly was hidden between visible pixels, only approximate. So yes you are correct, just described it a bit differently.

[–] lightstream@lemmy.ml 1 points 7 months ago (1 children)

they, in fact, will have some understanding

These models have spontaneously acquired a concept of things like perspective, scale and lighting, which you can argue is already an understanding of 3D space.

What they do not have (and IMO won't ever have) is consciousness. The fact we have created machines that have understanding of the universe without consciousness is very interesting to me. It's very illuminating on the subject of what consciousness is, by providing a new example of what it is not.

[–] rdri@lemmy.world 0 points 7 months ago

I think AI doesn't need consciousness to be able to say what is on the picture, or to guess what else could specific details contain.
