I don’t get this: “What that means is not only that they learn what it means to be a dog or a cat, …“ We don’t have any dataset of dog or cat experience right? OP probably means that he models learns wat a dog or cat is, right? I find the whole piece somewhat vague btw. No real insights if you ask me. Sure if all you put in is a dataset, that should be all you get out. What’s surprising (worth HN) here?

> “What that means is not only that they learn what it means to be a dog or a cat, …“

I think he's referring to the famous paper: "What is it like to be a bat"

Of course architecture matters in this regard lol. Comparing a CNN to a transformer is like comparing two children brought up in the same household but one has a severe disability.

What I meant in this blog post was that given two NNs which have the same basic components that are sufficiently large and trained long enough on the same dataset, the "behavior" of the resulting models is often shockingly similar. "Behavior" here means the typical (mean, heh) responses you get from the model. This is a function of your dataset distribution.

:edit: Perhaps it'd be best to give a specific example: Lets say you train two pairs of networks: (1) A Mamba SSM and a Transformer on the Pile. (2) Two transformers, one trained on the Pile, the other trained on Reddit comments. All are trained to the same MMLU performance.

I'd put big money that the average responses you get when sampling from the models in (1) are nearly identical, whereas the two models in (2) will be quite different.

I took the Andrew Ng Coursera machine learning course in 2015 and to this day I still remember him saying this in one of the videos. At the time he was talking about various versions/optimizations of gradient descent but he essentially said that tweaking the algorithm will only make your model ~1% better while doubling the amount of training data will have a substantially larger impact (use any old algorithm but just throw more data at the problem). That's why it was already evident back then that Google, Facebook, etc were sitting on a goldmine because in the long run those with the most data, not the brightest PhDs will win this race.

This insight makes one wonder if the same thing applies to humans as well. Are we just the sum of our experiences? Or the architectures of our brains are much more complex and different so that they have more influence on the outputs for the same inputs?

This makes me sad, not because I disagree with it, but because it's basically common wisdom in the statistical and ML communities (of practitioners). In my experience, the only people who think architecture/model choice makes a huge difference are n00bs and academics. That being said, definitely if you use a linear model (like lasso) vs a tree based model (like XGBoost), you'll see differences, but once you have a fl…

> the only people who think architecture/model choice makes a huge difference are n00bs and academics.

Are you referring to the current state of our best existing models or the potential future of ML? I find it incredibly hard to see how an LLM could implement the best “physically allowable” approximation to Solomonoff induction.

Then again, I thought it was extremely unlikely neural networks would have the abilities they currently exhibit, so who knows.

> It is a giant pain in the ass but you have to spend the time sitting in front of the screen going through the data and removing things and tagging things and making sure that the details are right. This is really what makes the good models good and the rest mediocre. In some other comment I read this. Sounds very much like a curation thing. And now I'm wondering; isn't this part already covered by a lot of human be…

Yeah when you use OpenAI you are giving them free labor for data curation.

This "n00b" seems to disagree with your sentiment on the importance on architecture: https://news.ycombinator.com/item?id=40155667

There’s some enormous caveats to this.

The model architecture is 100% the thing that makes LLMs special. You would not get this doing token prediction with word2vec.

The model sizes are also hugely important. Adding billions of parameters does introduce the capability to fit to new features.

The models eventually reach saturation of how much they can fit to. There’s reason to believe that current LLMs are underfit to what their sizes could theoretically utilize, but it could also be that the optimization algorithms are simply not capable of easily and efficiently utilizing another 2x data to fill out the space. Doubling the model size, on the same training data, and letting it be even more underfit could result in a better model.

There's not many people who will proudly announce their employer, their name, and where someone can stick it over the course of two public comments these days.

You, sir, are my hero.
