Back when I was getting my econ degree, we were taught about the Ultimatum game, which goes like this: You get two participants who don't know each other and will (ostensibly) never see each other again. You give one of them $100, and they make an offer of some portion of it to the other. If the other accepts, both parties keep their portion - so, if A offers B $20, and B accepts, A keeps $80 and B keeps $20, if B re…

I'm long on synthetic data. If you think about evolution and hill climbing, of course it works. You have a pool of information and you accumulate new rearrangements of that information. Fitness selects for the best features within the new pool of data (For primates, opposable thumbs. For AI art, hands that aren't deformed.) It will naturally drift to better optima. RLHF, synthetic data, and enrichment are all we need…

It's important to climb the right hill.

> If you think about evolution and hill climbing, of course it works. You don't even need to go that far. How do most children learn? By reading textbooks and listening to lesson plans assembled by their teachers from all the relevant content the teachers have experienced. Our education systems are built on synthetic data that is created for optimized learning, so that every child doesn't have to prove the universe f…

By this reasoning wouldn’t all information that you didn’t discover yourself be synthetic data?

I find nothing wrong with your statement. I am curious about the paper's use of "indiscriminate." I read this as "just feed the AI more AI output without care" which one can indeed do deliberately.

Seems to me that deliberate discriminate use should yield better against expectations.

Came here to say the same. "indiscriminate" doesn't really make sense. It's very deliberate.

However, there is one scenario: Scraping of web data. In that case, AI labs might know what is model generated.

The Ultimatum game is a useful insight into human psychology: for one thing, it tells us who thinks that the defector in this equilibrium is better off than a counterfactual cooperator. Ah, but they have their pride! Ok. My pride is not affected by someone else having 99 bucks they didn't ear…

Indeed. You’re very wise!

Cheese and Chalk. It is very different to generate synthetic datasets to assist in targeted training , vs ingesting LLM output from web scraping.

Yes -- said another way, if you're an ML researcher and you have human-provided (scraped) data, and an ability to generate synthetic data, then until recently, you had a controllable parameter: how much of your training data for your new model should be synthetic? You can vary this, run multiple experiments, and choose how much synthetic data to use -- and you can vary the specific configs about how that synthetic da…

You still have some that control, but in a much more indirect way.

There are three kinds of data now, synthetic, pre-2022 and current. Everything pre-2022 is definitely written by humans, synthetic data is still synthetic, and post-2022 is a mix of both.

I wouldn't be surprised if "AI detectors" work somewhat for this use case. They're biased, far from accurate and a terrible idea if you need to make important decisions (like whether to expel a student for cheating), but there's quite a large room for errors here.

This misunderstands fitness. Its not a sure bet what is most optimal is what you see. “Good enough” given environmental context is what you see. Just like with certain crystal structures in chemistry, you may only be in a localized threshold of fitness stability that is not necessarily optimal, but separated from another optimal configuration by having suboptimal intermediary steps that need more activation energy to overcome before falling into a state with lower entropy (or more optimal fitness).

In other words you can never be sure if synthetic data is any good or if what things gravitate toward are really most optimal.

That isn't synthetic data in any reasonable or meaningful sense of the term. You could describe a textbook as a synthesis, sure, in a sense which absolutely does not track with the 'synthetic' in 'synthetic data'. Unless the textbook is AI-generated, and I expect that in 2024, the number of AI-generated textbooks is not zero.

It’s an analogy. The learning materials teachers create for students is very much like synthetic data, it’s just not assembled from algorithmic output.

kids learn, walking talking reading arithmetic and physics, by doing things in the physical world. Adults may speak differently to kids than adults, but it's a stretch to say it's synthetic. Equivalent to synthetic would be a group of kids that just grew up together and made up a novel language.
