From whence are you quoting the phrase "dumb search?"

"AlphaProof is a system that trains itself to prove mathematical statements in the formal language Lean. It couples a pre-trained language model with the AlphaZero reinforcement learning algorithm, which previously taught itself how to master the games of chess, shogi and Go."
Yeah I am not clear the degree to which this system and LLMs are related. Are they related? Or is AlphaProof a complete tangent to CHatGPT and its ilk?
It's a math Language Model. Not even sure it's a Large Language Model. (Maybe shares a foundational model with an English LLM; I don't know)
It learns mathematical statements, and generates new mathematical statements, then uses search techniques to continue. Similar to Alpha Go's neural network, what makes it new and interesting is how the NN/LLM part makes smart guesses that drastically prune the search tree, before the brute-force search part.
(This is also what humans do to solve math probrems. But humans are really, really slow at brute-force search, so we really almost entirely on the NN pattern-matching analogy-making part.)

The success in Go was very much not dumb search. Where dumb search had failed to achieve the level of even a very weak player, the neural net's "intuition" about good moves without any search was already very strong. Only the combination was superhuman, and that was anything but the dumb search that had been tried before. Today's announcement is also not about proving Lean theorems by "dumb search". The success is ab…
Clever forms of "dumb search" that leverage compute, DNNs, RL, self-play, and/or formal languages are not dumb at all.
I put the words "dumb search" in quotes precisely because I think critics who dismiss AI progress as such are missing the point.
We're not in disagreement :-)

And why aren't you complaining that human participants could train and study for thousands of hours before attempting the problems? And that the training materials they used was itself created and perfected by hundreds of other people, after having themselves spend countless hours studying?
Because so did the AI?

Don't confuse interpolation with extrapolation. Curing cancer will require new ideas. IMO requires skill proficiency in tasks where the methods of solving are known.
The methods are know, but the solutions to the IMO problems weren't. So the AI did extrapolate a solution. Also, there's no reason to affirm that an eventual cure for cancer requires fundamentally new methods. Maybe the current methods are sufficient, it's just that nobody has been "smart" enough to put the pieces together. (disclaimer: not an expert at all)

That's in fact precisely my point: Clever forms of "dumb search" that leverage compute, DNNs, RL, self-play, and/or formal languages are not dumb at all.

Right. My point is that you're attacking a position that no real critic holds. Of course we're in agreement then!
"Clever forms of dumb search are not dumb" feels a little like kicking down open doors. We were always going to agree.
Re: AI solves International Math Olympiad problems at silver medal level
#218(It's not my main point, but it's always worth remembering - even aside from any AI context - that many top mathematicians can't do IMO-type problems, and many top IMO medalists turn out to be unable to solve actual problems in research mathematics. IMO problems are generally regarded as somewhat niche.)
Re: AI solves International Math Olympiad problems at silver medal level
#219This is a fun result for AI, but a very disingenuous way to market it. IMO contestants aren't allowed to bring in paper tables, much less a whole theorem prover. They're given two 4.5 hour sessions (9 hours total) to solve all the problems with nothing but pencils, rulers, and compasses [0]. This model, meanwhile, was wired up to a theorem proover and took three solid days to solve the problems. The article is extrem…
Re: AI solves International Math Olympiad problems at silver medal level
#220So I am extremely hyped about this, but it's not clear to me how much heavy lifting this sentence is doing: > First, the problems were manually translated into formal mathematical language for our systems to understand. The non-geometry problems which were solved were all of the form "Determine all X such that…", and the resulting theorem statements are all of the form "We show that the set of all X is {foo}". The do…
