    That’s surprisingly accurate, as people here are highlighting (it makes geometrical sense when dealing with complex numbers).

    My nephew once asked me this question. The way that I explained it was like this:

    • the friend of my friend is my friend; (+1)*(+1) = (+1)
    • the enemy of my friend is my enemy; (+1)*(-1) = (-1)
    • the friend of my enemy is my enemy; (-1)*(+1) = (-1)
    • the enemy of my enemy is my friend; (-1)*(-1) = (+1)

    It’s a different analogy but it makes intuitive sense, even for kids. And it works nice as mnemonic too.




  • Persuasion itself goes from neutral to negative, depending on your moral standards. (They’re partially individual, partially cultural.) Because at the end of the day it boils down to “I want you to believe in this, because I benefit from your belief.”

    And you definitively see some backslash against this aspect of advertisement; same deal with personal communication, a person being excessively rhetoric for their own benefit is immediately labelled distrustful.

    Then over that propaganda adds further layers of nastiness, like:

    • Often, the one doing propaganda is supposed to defend your interests. Not their/its own.
    • You’ll usually need to omit and lie far more for propaganda than for other things. Because it’s usually a complex matter that involves society as a whole, not just your personal decision.
    • Since the political landscape changes, the discourse being propagated may flip 180°.

  • Let’s go simpler: what if your instance was allowed to copy the fed/defed lists from other instances, and use them (alongside simple Boolean logic plus if/then statements) to automatically decide who you’re going to federate/defederate with? That would enable caracoles and fedifams for admins who so desire, but also enable other organically grown relations.

    For example. Let’s say that you just joined the federation. And there are three instances that you somewhat trust:

    • Alice - it defederates only really problematic instances.
    • Bob and Charlie - both are a bit prone to defederate other instances on a whim, but when both defed the same instance it’s usually problematic.

    Then you could set up your defederation rules like this:

    • if Alice defed it, then defed it too.
    • else, if (Bob defed it) and (Charlie defed it), then defed it too.
    • else, federate with it.

    Of course, that would require distinguishing between manual and automatic fed/defed. You’d be able to use the manual fed/defed from other instances to create your automatic rules, to avoid deadlocks like “Alice is blocking it because Bob is blocking it, and Bob is blocking it because Alice is doing it”.


  • The source that I’ve linked mentions semantic embedding; so does further literature on the internet. However, the operations are still being performed with the vectors resulting from the tokens themselves, with said embedding playing a secondary role.

    This is evident for example through excerpts like

    The token embeddings map a token ID to a fixed-size vector with some semantic meaning of the tokens. These brings some interesting properties: similar tokens will have a similar embedding (in other words, calculating the cosine similarity between two embeddings will give us a good idea of how similar the tokens are).

    Emphasis mine. A similar conclusion (that the LLM is still handling the tokens, not their meaning) can be reached by analysing the hallucinations that your typical LLM bot outputs, and asking why that hallu is there.

    What I’m proposing is deeper than that. It’s to use the input tokens (i.e. morphemes) only to retrieve the sememes (units of meaning; further info here) that they’re conveying, then discard the tokens themselves, and perform the operations solely on the sememes. Then for the output you translate the sememes obtained by the transformer into morphemes=tokens again.

    I believe that this would have two big benefits:

    1. The amount of data necessary to “train” the LLM will decrease. Perhaps by orders of magnitude.
    2. A major type of hallucination will go away: self-contradiction (for example: states that A exists, then that A doesn’t exist).

    And it might be an additional layer, but the whole approach is considerably simpler than what’s being done currently - pretending that the tokens themselves have some intrinsic value, then playing whack-a-mole with situations where the token and the contextually assigned value (by the human using the LLM) differ.

    [This could even go deeper, handling a pragmatic layer beyond the tokens/morphemes and the units of meaning/sememes. It would be closer to what @njordomir@lemmy.world understood from my other comment, as it would then deal with the intent of the utterance.]



  • Not quite. I’m focusing on chatbots like Bard, ChatGPT and the likes, and their technology (LLM, or large language model).

    At the core those LLMs work like this: they pick words, split them into “tokens”, and then perform a few operations on those tokens, across multiple layers. But at the end of the day they still work with the words themselves, not with the meaning being encoded by those words.

    What I want is an LLM that assigns multiple meanings for those words, and performs the operations above on the meaning itself. In other words the LLM would actually understand you, not just chain words.



  • At the very least, I’d recommend you:

    • gloves - because you’ll get really close to that gross shit. You don’t want to touch it.
    • a sponge - it doesn’t need to be new; your old kitchen sponge is enough, just don’t use it again in the kitchen. Use the yellow side to spread the cleaning agent, and the green side to remove obnoxious grime stuck to something. (Do it gently, and only with a really old sponge, to avoid scratching the surface.)
    • a bucket - mostly to mix some soap and water.
    • a dry rag - mostly for finishing/drying. A cringey old shirt that you won’t be using again is usually enough.
    • toilet brush - don’t use the sponge to clean inside the toilet bowl; you’ll be spreading the bacteria from your shit and piss to the rest of the restroom.

    Everyone has the cleaning agents that they swear upon, so look for something that works for you. For me it’s

    • alcohol vinegar - to get rid of that brown crust in the sink (water in my city is hard as a brick) and around the shower drain. I usually apply it, wait a few minutes, then use the sponge to scrub it a bit. Then I remove the vinegar with the rag.
    • bleach - exclusively used inside the toilet bowl. I squish some bleach there, then scrub it with the toilet brush, then flush it off, making sure that there’s no bleach behind.
    • disinfecting agent - I squish a bit of that inside the toilet bowl and just leave it there. It smells good, and it gets rid of the bacteria.
    • an ammonium-based cleaning agent - I squish it on obvious grime on the walls (except the above), then scrub it with the sponge.
    • soap and water - to “wash” the walls with the sponge.
    • plain water with some disinfecting agent - to rinse it. Then I just remove the excess water with the rag and let the restroom to dry naturally (with closed doors otherwise my cats will step on the bathroom, step outside, and now I got to clean the bathroom again plus the corridor and furniture).

    Important detail: do not mix any two of the cleaning agents that I’ve mentioned. Specially not ammonium and bleach.

    For reference, the disinfecting agent that I use is called “pinho sol”, but I have no idea if it’s sold outside Brazil. You probably have some similar product wherever you live.


  • Complexity does not mean sophistication when it comes to AI and never has and to treat it as such is just a forceful way to make your ideas come true without putting in the real effort.

    It’s a bit off-topic, but what I really want is a language model that assigns semantic values to the tokens, and handles those values instead of directly working with the tokens themselves. That would be probably far less complex than current state-of-art LLMs, but way more sophisticated, and require far less data for “training”.





  • Chomsky’s concept of UG (universal grammar) is able to handle this. Since there would be a chunk of language that is innate (universal), that feral child would share it. So, as a conclusion from that, even if the feral child isn’t expressing it through vocalisation, since they lack an “application” of the UG (like Nahuatl, Mandarin, Quechua, English, Kikongo etc.), they’d still have some rather simple internal monologue.

    …that said I think that Chomsky’s UG is full of shit. I do agree with him that the faculty of language might have developed first to structure thought; but my reasoning resembles a bit more yours, the role of language would be to formalise thought. Thinking without language is possible in the same way as moving across a village without roads - it’s doable but clunky, and you’ll likely take far more effort than with proper roads/ a language.

    Not to challenge Chomsky on his own turf

    Don’t worry. Everyone and their dog challenges him. Including himself, he’s often contradicting his own earlier statements.


  • It depends a lot on what you consider “toxic”.

    If it’s just about intrusive off-topic political discussion, then I fully agree with you: it’s far more common in Lemmy than in Reddit, and sometimes it reaches a point that even people who’d otherwise enjoy discussing politics roll their eyes and say “not this shit again”.

    However, if “toxic” includes other forms of undesirable behaviour, then Lemmy is probably less toxic than Reddit. For example: while sometimes you do see here disingenuous and deliberate stupidity, “waah TL;DR!!”, the “I don’t understand” conveying disagreement, or passive aggressiveness, in Reddit they pop up all the time.

    So, what do you consider toxic? Depending on that, the other users’ experiences might be really similar or really different from yours.
