Google CEO Sundar Pichai says problems with its AI can't be solved because hallucinations are an inherent problem in these AI tools.

You know how Google’s new feature called AI Overviews is prone to spitting out wildly incorrect answers to search queries? In one instance, AI Overviews told a user to use glue on pizza to make sure the cheese won’t slide off (pssst…please don’t do this.)

Well, according to an interview at The Vergewith Google CEO Sundar Pichai published earlier this week, just before criticism of the outputs really took off, these “hallucinations” are an “inherent feature” of  AI large language models (LLM), which is what drives AI Overviews, and this feature “is still an unsolved problem.”

    no, the truth is it’s impossible even then. If the result involves randomness at its most fundamental level, then it’s not reliable whatever you do.

      Sure, the AI is never going to understand what it’s doing or why, but training it on better datasets certain WILL improve the results.

      Garbage in, garbage out.

        You can train an LLM on the best possible set of data without a single false statement and it will still hallucinate. And there’s nothing to be done against that.

        Without understanding of the context everything can be true or false.

        “The acceleration due to gravity is equal to 9.81m/s2” True or False?

        LLM basically works like this: given the previous words written and their order, the most probable next word of the sentence is this one.

          Well yes, I’ve seen those examples of ChatGPT citing scientific research papers that turned out to be completely made up, but at least it seems to be a step up from straight up shitposting, which is what you get when you train it on a dataset full of shitposts.

            Well it’s definitely true that you will have hard times getting true things from garbage. But funny enough, the model might hallucinate true things:)

        The problem is that given the way they combine things is determine by probability, even training it with the greatest bestest of data, the LLM is still going to halucinate because it’s combining multiple sources word by word (roughly) guided only by probabilities derived from language, not logic.

          Yes, I understand that. But I’m fairly certain the quality of the data will still have a massive influence over how much and how egregiously that happens.

          Basically, what I’m saying is, training your AI on a corpus on shitposts instead of factual information seems like a good way to increase the frequency and magnitude of such hallucinations.

            Yeah, true.

            If you train you LLM on exclusivelly Nazi literature (to pick a wild example) don’t expect it to by chance end up making points similar to Marx’s Das Kapital.

            (Personally I think what might be really funny - in the sense of laughter inducing - would be to purposefull train an LLM exclusivelly on a specific kind of weird material).

              Yeah, I mean that’s basically what GPT4Chan did, which someone else already mentioned ITT.

              Basically, this guy took a dataset of several gigabytes worth of archived posts from /pol/ and trained a model on that, then hooked it up to a chatbot and let it loose on the board. You can see the results in this video.
