A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.
Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

I guess the important thing to understand about spurious output (what gets called "hallucinations") is that it's neither a bug nor a feature, it's just the nature of the program. Deep learning language models are just probabilities of co-occurrence of words; there's no meaning in that. Deep learning can't be said to generate "true" or "false" information, or rather, it can't be meaningfully said to generate information at all.
So then people say that deep learning is helping out in this or that industry. I can tell you that it's pretty useless in my industry, though people are trying. Knowing a lot about the algorithms behind deep learning, and also knowing how fucking gullible people are, I assume that—if someone tells me deep learning has ended up being useful in some field, they're either buying the hype or witnessing an odd series of coincidences.
The thing is, this is not "intelligence" and so "AI" and "hallucinations" are just humanizing something that is not. These are really just huge table lookups with some sort of fancy interpolation/extrapolation logic. So lot of the copyright people are correct. You should not be able to take their works and then just regurgitate them out. I have problem with copyright and patents myself too because frankly lot of it is not very creative either. So one can look at it from both ends. If "AI" can get close to what we do and not really be intelligent at all, what does that say about us. So we may learn a lot about us in the process.
I guess there's a sense in which all computer science is table lookups, but if you want a nauseatingly technical summary of deep learning—it's high-dimensional nonlinear regression with all the methodological seatbelts left unfastened.
The only thing this says about us is that philosophical illiteracy is a big problem in the sciences, and that computer science is the most embarrassing field in all STEM. Otherwise, you know, people find beauty in randomness (or in stochasticity, if you prefer) all the time. This is no different.
