I wonder how much safety work they have to do specifically because of this. I’d imagine their model might have a fairly paranoid, slightly racist bias if not. Particularly as younger demographics shifted away from FB in the last decade.

Actually if you want to train a model that can recognize bad things you want to have those bad things in the language model training data, otherwise it won’t see the characteristics of those things and it will later struggle to recognize them in later training stages.

Presence may be necessary, but researcher-driven weighting of different sources of content can still introduce bias. For instance, [0] suggests (sources are unclear) that OpenAI boosted by 5x the weight of their WebText2 dataset, which consists of sites linked to by upvoted Reddit comments. Reddit, in this sense, with all the biases of its various communities, was artificially elevated in importance. (Per [1], there were well-thought-through reasons for this around previous failures due to overreliance on Common Crawl, but it's nonetheless a choice that was made by humans to go in this direction.)

I haven't worked at facebook for a number of years but I'm imagining what they trained on here was public instagram images and not the random text that people write on facebook. The text in facebook posts is likely to be low value but the images are a data gold mine.

That would be supervised learning: they tell the model that these are undesirable::racist values. Or just fed into the RAG::blacklist dataset.

It just makes it less likely that these normal people will be able to see the other normal posts from other normal people. Early Facebook's Wall was like that, mostly just friends chatting with each other about cats and babies, but then the company purposely started to optimize the timeline for controversy instead and it all went downhill.

It's not that there aren't normal people on there, it's that organic feel-good posts have a harder time gaining traction vs the sea of flamebait and sponsored ads and astroturfed spam. The signal to noise ratio was very, very low by the time I left. I don't know how it is these days...

Re:Meta fed its AI on everything adults have publicly posted... by SoftTalker on Friday September 13, 2024 @03:18PM (#41534234)
I mean technically they were optimizing for "engagement" but it turns out that things that get strong reactions from people tend to be controversy and rage-bait.
Re:Meta fed its AI on everything adults have publicly posted... by squigz on Friday September 13, 2024 @01:53PM (#41533488)

Does it? I deleted my Facebook back in 2016 or so when it got so bad. Before that, I used extensions to make it show posts from friends in chronological order instead of whatever it was optimizing for by default (engagement/controversy, I think?)

It's just such a toxic, manipulated environment... I don't use social media anymore, just text some friends, and am much happier.

I guess it's a gray area? It's more like a forum to me, of the pre-Facebook sort, more like Slashdot than reddit.

And there's extremely strong moderation here that does the opposite of Facebook: It optimizes against controversy and vitriol rather than encouraging it.

We end up with a bunch of nerds mostly talking shop and sometimes complaining about the job market, but that's still far less ragebaitey than most social media.

Re:Meta fed its AI on everything adults have publicly posted... by SoftTalker on Friday September 13, 2024 @03:24PM (#41534298)
And it's not just human moderation (which would be biased based on the moderator) but things like the flamewar detector which actively demotes content that is getting a lot of quick responses. This is precisely what Facebook would promote, and HN might also if they were dependent on ad revenue to fund the service.

Much of what's bad about Facebook and other social media pretty much boils down to their need to show as many ads to as many eyeballs as possible.

Something doesn't add up here. Nerds talking shop and controversy and vitriol about the their technical preferences is the same thing.

Perhaps what you're saying is that controversy and vitriol is only apparent when you're an "innocent bystander" who doesn't have a passion for the subject? Which HN avoids by usually remaining focused on a fairly narrow set of subjects, to a user base generally passionate towards those subjects, so you don't notice?

That is an astute observation, if that is what you're trying to say. Indeed, if you showed your non-technical grandmother HN, she would no doubt see it the way Facebook was talked about earlier.

Re:Meta fed its AI on everything adults have publicly posted... by solardev on Friday September 13, 2024 @02:32PM (#41533818)
OK, but I think there's a pretty big difference between "Next.js is too bloated, you should use HTMX" and "so and so group of people are all _____ and they should all be ________, and oh, your mom sucks".

I don't think – I hope, at least – no one is going to start a shooting war over their framework of choice. You can't say the same about much of the content circulating around social media.

(Edit: You added more to your post after I replied. To your point of "Which HN avoids by usually remaining focused on a fairly narrow set of subjects", that's not just my observation, that's the actual guidelines: https://news.ycombinator.com/newsguidelines.html. We self-select into a narrow slice of nerdtalk or we end up getting downvoted or banned from the site. To me that is the big difference between an interest-based forum that generally stays a functional monoculture vs a general social media site that brings diverse strangers together into shouting wars about whatever the controversy du jour is.)

Is there? Perhaps the trouble here is that your examples are too far apart to recognize how they compare?

What if Facebook, instead, said "Fat workers are too bloated, you should hire skinny workers"? Or if HN said "so and so projects are all ____ and they should all be ____, and oh, your vacuum doesn't suck".

I see no practical difference. It seems the only difference is that Facebook tends to talk about people, HN about tech. But that's not a significant distinction – aside from where your interests lie. Certainly tech-minded folks often find people to be uninteresting.

Re:Meta fed its AI on everything adults have publicly posted... by solardev on Friday September 13, 2024 @02:54PM (#41534013)
I think it's just the different degree of emotional attachment people to have to these topics. Yeah, people can get a bit worked up about how annoying JS development has become, but not quite to the same level as the major headlines of the day about the latest Middle East controversy/Soviet threat/identity politics thing.

Oh, and my vacuum does suck just fine, thank you very much.

Why do you say that? I share in the tech-minded proclivity towards not having much interest in people, so I admit to being largely out of the loop, but what is there to be worked up about where you wouldn't equally get worked up around some tech-based topic?

It just sounds boring an uninteresting to me. When I have encountered discussions about those topics, all I have is some laughter at how silly the people sound. Just like I'm sure how the "Next.js is awful" conversations sound to the metaphorical grandma.

Re:Meta fed its AI on everything adults have publicly posted... by solardev on Friday September 13, 2024 @03:05PM (#41534122)
You, yourself, might just be different/lucky then :) Or you could just be typical here. The average HN user is probably not representative of the average person in the overall population. It's a self-selecting crowd of nerds, many of whom aren't all that interested in more worldly topics. (Nothing wrong with that, mind you. It's part of the reason I'm here and not on mainstream social media.)

But out in the greater society, people get all worked up about those other topics, and will go protest in the streets, blockade representatives' houses, send death threats, rage endlessly online, attempt assassinations, go on shooting sprees, etc. Those things are usually triggered by some emotional attachment to some tribal identity and anger towards some out-group.

In a monoculture like this, we're mostly peers. Yeah, we might disagree about some particular things, but there's less of an "us vs them" mindset as you see politics, geopolitics, values-based communities, etc.

Discussions of technical merit, even when heated, thankfully don't reach those emotional heights quite as often. In my experience, at least...

Re:Meta fed its AI on everything adults have publicly posted... by randomdata on Friday September 13, 2024 @03:13PM (#41534192)
> But out in the greater society, people get all worked up about those other topics

I understand that. Believe me, I can definitely get worked up about Next.js, if you really want to go there...! It is in no way surprising that people interested in people can end up in the same place around topics related to people.

> In my experience, at least...

But the underscore here is that your experience is based on where your interests (perhaps not the perfect word to describe this, but it's what I got) lie. If you have a greater interest in people, you're going to feel more strongly about it. I'm not bothered by it at all.

But, by the same token, what is to say that I don't feel more strongly towards technical controversy than you do?

Re:Meta fed its AI on everything adults have publicly posted... by solardev on Friday September 13, 2024 @03:16PM (#41534216)
You very well might! No algorithm is perfect, and no moderation system will get it right every time. But I hope your experience on HN is still a net positive.

> no moderation system will get it right every time.

It doesn't need to, of course. Moderation, outside of blatant spam perhaps, is rather pointless. If someone wants to exclaim "Next.js is the second coming of Jesus", I want to hear it. There is a reason they are saying it.

To not get stuck in my bias: For those interested in people, why wouldn't you want to hear "so and so group of people are all _____ and they should all be ________, and oh, your mom sucks"? It is a ridiculous statement at face value, admittedly, but it is someone's attempt at communicating. What they are actually trying to say might teach you something important. Wouldn't you want to surface what they are truly trying to get at?

I certainly would for its tech-based counterpart. Especially if it seems to contradict what I hold dear.

> But I hope your experience on HN is still a net positive.

Naturally! I'm out of here the second it is in any way not positive. No sense wasting your free time on something you don't enjoy.

Re:Meta fed its AI on everything adults have publicly posted... by squigz on Friday September 13, 2024 @05:33PM (#41535381)
> Is there?

The difference is that talking about a framework with passion doesn't generally end up with severe real world consequences for other people.

The difference between tech and people is that people are... people. They have lives, feelings, all those fun human things. Passionately talking about how X group of people should die (or <insert rhetoric of your choice>) is quite different than passionately talking about how Y framework is the worst thing programmers have ever concocted. Generally the latter won't end up with someone getting stabbed. (Generally...)

> What if Facebook, instead, said "Fat workers are too bloated, you should hire skinny workers"? Or if HN said "so and so projects are all ____ and they should all be ____, and oh, your vacuum doesn't suck".

I think this is a terribly unfair switcharoo to make. Let's fill in the blanks for that second quote.

A technology may not be literally stabbed, but I think it is fair to say that it very well may get stabbed metaphorically. It may even lead to the complete demise of the technology.

Passionately calling for the death of Next.js isn't really any different than calling for the death of a person, other than you may perceive it as being different if you hold people more dear than technology. But, in that case, that's just your arbitrary opinion that means nothing to anything other than you. There are no doubt some who would be more concerned about the loss of Next.js (bad example; nobody would miss Next.js, but you get the idea) than the loss of a person, which is equally valid. The true arbiter of truth, the universe, certainly doesn't have greater feelings towards one than the other.

What you get from the self-supervised training of a base model is more like "language fluency plus a web of crystallized-knowledge relationships."

But also, ML model training is a bit like the stock market: the noise/stupidity in individual examples points in a bunch of random directions, and so ends up cancelling out; while the signal all points in the same direction, and so ends up captured in the distilled model. (You might call this the "Anna Karenina principle of Information Distillation": all right answers are the same, while each wrong answer is wrong in a different way.)

A great point, and a real problem, but I think in the grand scheme of things, the models inherit those problems while also simultaneously inheriting all kinds of useful knowledge about information and how to communicate effectively and dynamically with that information. It coexists with the benefit rather than serving as a defeater of the idea that there's any benefit.

It's still wrong if the majority is wrong, isn't it? Like propaganda on major channels which praise the same thing, is consumed by a major part of the population which then assume that it's the right thing and continue the misinformation, which then propagates to the AI model.
Re:Meta fed its AI on everything adults have publicly posted... by derefr on Friday September 13, 2024 @02:35PM (#41533845)
Yes; but in the case of a "common misconception" like this, there's always also a nontrivial minority who do know the "right answer"[1] — and so enough examples of that occur in the training data to enable the model to embed the knowledge-web of "right ideas" (as a niche activation), alongside the "wrong idea" (in its default-mode network).

The "initial fine-tuning of a 'raw' base model to produce a 'generalized pre-trained' base model" process, is commonly talked about in terms of "alignment" — making the model ethical, making it not swear at you, making it refuse to engage with certain content, etc. And really, that part is all optional, with there existing "non-aligned" or "orthogonalized" models that don't have these steps performed on them or have had them reversed, but which are still useful.

But a large part of this initial fine-tuning process, consists of debiasing the model's default activation, moving it away from making associations with "common misconceptions" and toward making associations with "right answers." And this process is crucial to a model being able to reason intelligently — as these common misconceptions aren't coherent in a chain of reasoning they appear in, and so lead to the chain of reasoning falling apart / being non-productive. This is, in large part, the "secret sauce" that makes a model of a given size "more intelligent" than another model of the same size.

Every base model that anyone actually cares about or uses — "aligned" or not — has had some process of de-biasing like this applied to it; or, at least, has short-cutted this process by training on a training dataset generated by or filtered by a model that has already had this de-biasing applied to it, such that the derived training dataset doesn't contain the "common misconceptions" in the first place.

And when OpenAI and Meta brag about using RLHF, a large part of what they mean, is crowdsourcing recognition of long-tail "common misconceptions" at scale, to allow a much more thorough version of this de-biasing process[2].

---

[1] Of course, if nobody in the training data ever demonstrates the "right answer" knowledge/associations, then the model will never learn that knowledge/associations. But then, given that these training datasets usually represent decent samples of the population, a "right answer" being missing entirely would likely mean that nobody on Earth knows the "right answer" — so we humans wouldn't be able to recognize the model was wrong. The stock market can be wrong too, for the same reason.

[2] Which, perhaps surprisingly, can add up to more than the sum of its parts. The more of this human-labelled "common misconception"-response RLHF data you have, the more you can derive patterns from this bias data. You can distil out negative examples that you can use to prompt a model to filter the training dataset; but more interestingly, you can distil positive examples of the sort of structured chains of reasoning that work best to inherently avoid triggering the bias. Where, if you can overlap the activation-space hyperspheres of many such inversion-of-bias examples, then you get, essentially, the hypersphere within the model's activation space that contains its instrumental rationality. You can then just bias the model toward living in that part of activation space as much as possible — and this shoots its apparent reasoning capacity way up.

There's a fun retrospective PoV which is that Silicon Valley has been through a sequence of consecutive hype waves, each of which has been viewed with derision as mega-scale fraud or brainrot:

- Video games (epic waste of time and moral debasement) gave us GPUs and NVIDIA

- Social media (rage bait-fueled argument machine and cat pic repository) gave us a huge corpus of text on which to train language models. Yes scientific papers and Wikipedia are necessary but probably not sufficient?

- Crypto (fraud, giant waste of resources) gave us a generation of young people who were comfortable building ludicrously oversized GPU clusters, and to some extent funded NVIDIA and TSMC R&D

all of which led to where we are with AI, which is that it is making (in my humble opinion) impressive dents in the problem of solving intelligence -- cue HN commenters telling me that AI is a giant fraud and waste of resources also :)

I don't know why that's funny, since that is the very essence of the ideal of democracy: the distillation or averaging of the sentiment of the masses yields truth. Some contributions are outliers in one way or another, and it's these outliers that live in many people's heads, but these extremes are ironed out by averaging against the masses.
