If Mamba really was as capable as a Transformer on tasks requiring accurate attending to long context, then there'd be no need for Jamba (Mamba+Transformer hybrid).

Your argument of "if we train a Mamba SSM to be as good as a Transformer, then it'll be as good as a Transformer", seems a tad circular...

Has anyone tried removing an entire concept from a dataset and seeing if the LLM can reason its way into the concept? I think that would be a really cool experiment. There are probably some really good candidate concepts that just take a small leap of reasoning to reach. But off the top of my head maybe multiplication? Or the concept of zero. Maybe the wheel? Edit: if anyone is interesting in doing this kind of stuff…

I want to see an LLM that generates answers without the letter 'e', like the novel Gadsby by Ernest Vincent Wright.

If you had one that was character based (instead of the weird encoding they tend to use), you could directly sample without e.

Though I'm not sure its output would make much sense, and you might have to use beam search (or something like backtracking).

I wonder how you would train a model to directly speak without e. Perhaps you use the general model like above with beamsearch, and then train a new model to directly predict the first models beamsearched-predictions.

> 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…

People typically ask LLMs about things they DON‘T know about or understand. So they are not qualified to assess the validity of their answers. Which is exactly why hallucination is such a big problem.

> People typically ask LLMs about things they DON‘T know about or understand. So they are not qualified to assess the validity of their answers.

Eh, you can still often (!) figure out whether what the LLM says makes sense.

Just like you can often figure out whether a human is bullshitting, by fact checking with other sources, or going over their reasoning.

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…

We manage to train neural nets to approximate complicated data sets via rather simple process: back propagation.

It is indeed a marvel that it works nearly as well as it does.

But then again, evolution is even dumber (in the sense that it only makes random choices that thrive or perish, and can't even take gradients into account), but evolution has still managed to produce intelligent critters.

I guess when you have enough dimensions greedy approaches to optimisation / hill climbing can work well enough, even when you have challenging problems?

Especially if you are allowed to move to some meta levels. Eg evolution doesn't build planes, it built brains that can figure out how to build planes. Similarly with back propagation perhaps.

Please humor me for a moment, because I'm having trouble seeing why this is not just true by definition. Doesn't "training to the same performance" mean that you get the same responses? Or from a different angle: given that the goal of the model is to generate plausible completions based on a training dataset, it seems like plausibility (and therefore performance) is obviously defined by the dataset.

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?

I think it's the latter. We may well have some subsystems that work like LLMs or other current AIs, but the overall system of a human mind seems to work in a fundamentally different way, as it's able to make good creative choices (such as the next word to say) without looking at lots of options.

Consider a chess engine that plays at grandmaster level, i.e. a human grandmaster can sometimes beat it. Even though it's not the best chess engine in the world, it simulates billions of possible scenarios to decide each move. Yet the grandmaster can still beat it sometimes, even though he clearly isn't thinking about billions of possible scenarios. (On the question of whether human brains may in fact unconsciously process billions of possibilities when deciding a chess move, using some neurological process we haven't discovered, I've heard David Deutsch argue this would be thermodynamically impossible as it would require far more energy than the brain consumes.) So the human grandmaster's brain must be doing something else that we don't understand. I think a similar comparison applies with how an LLM and a human choose the next word to say. An LLM has to run a giant statistical search for candidates. Humans seem to be doing something else.

The most notable voice refuting this opinion on Twitter was Yi Tay (founder of Reka.ai), who definitely does not belong to either of those categories!

Tay (ex. Google Brain) founded Reka.ai two years ago, and their latest multimodal language model is close to SOTA in performance.

Yeah, I'm not sure how someone could interpret what you said in the way people are citing here. It's actually obvious that you are right in the context of data in LLMs. Look at LLAMA 3, for example there are minimal architectural changes, and its performance is almost at the level of GPT-4. The biggest change was in the dataset.

>In my experience, the only people who think architecture/model choice makes a huge difference are n00bs and academics. There are countless competitions, etc. on Kaggle, AICrowd, or other platforms with an enforced standardized data set. Every entrant uses the same data set and there's a huge difference between the best and worst submissions.

Agreed but if you look at winning submissions which i did stop doing, a lot of them do very good feature engineering which is not a model related thing.
