AI

I am interested in how AI systems can reason more reliably (one of the main issues with LLMs).

I have some notes on the more classical side of AI/automated reasoning.

Some of my biases

  1. Compared to most AI researchers, I'm not very bullish on LLMs, even with enhancements like CoT. I think (as of mid 2024) we have already seen most of the use cases we are going to get out of them—generally (1) things like search and summarization where a high error rate is tolerable, (2) domains that are highly rote (e.g. standardized tests, boilerplate code, front line customer support), or (3) things that were already doable with ML but are now easier because they can be achieved just by prompting. But I'm only ~80% confident of the above, and even if I'm right, there could still be other architectures inspired by or built on LLMs that might fare better.
  2. I think GOFAI—things like logic and heuristic search—is underestimated. That body of scholarship always had its problems, especially around knowledge acquisition and representation of uncertainty, but there was also something right about it: it is interpretable and it directly captures desirable invariants (e.g. in formal logic you always have modus ponens available, as you should; by contrast an LLM might neglect to apply, or misapply, modus ponens based on any number of inscrutable contextual factors).
  3. I think psychology and linguistics are also underestimated sources of inspiration for AI.
  4. I think often in AI we try to run before we can walk—that is, to attack complex problems when we can't even solve simple ones. It's no mystery why: a 50% solution to a real business problem can be a lot more economically valuable than a 100% solution to a toy problem. But the latter may be what is needed to advance scientifically. For this reason I think projects like the ARC Prize are valuable.

Random info

From Boston, now in SoCal. In my free time I dabble in various things such as ultimate, pickleball, piano, and Japanese. I've written some notes on math contests (from long ago when I taught that material), accounting, and motivation/procrastination.
