It's not just you! Here's a lovely quote from an influential paper, "We offer no explanation as to why these architectures seem to work; we attribute their success, as all else, to divine benevolence." I think people wen

Cool. It looks like you're packaging the data as json files in the repo. Would be neat to see the pipeline that collects it.

This is very cool! I was wondering why there's factor of ~50 in the ICE index formula. It turns out that factor was selected when the changeover from local currencies to euro happened. The multiplier makes the old formulation agree wit

Still happens all the time in certain finance tasks (eg trying to predict stock prices), but I'm not sure how long that will hold. As for why that might be, I don't think I can do any better than linking to this comment about a co

Sorry, what I was clumsily trying to say is something like: "As an outsider to the startup world, your project has made me curious about the shape of the startup ecosystem as a whole. I bet you have the data to generate that picture! I

Very cool! It looks like you've purchased the data from a vendor, is that right? I love graphs of all kinds, so I was hoping to fetch the raw data and have a look at it with pyvis/networkx.

For some reason the article made me think about this quote from one of the 2025 MacArthur Fellowship videos, "I think there are some mathematicians who are kind of like the hiker who choose this massive peak they want to scale and they

Very cool appendix describing how they collected the data. I was kind of surprised to learn that they collected arXiv abstracts + metadata from Kaggle, but it definitely makes sense. I was also surprised that 6 years of SSRN papers was only

I've been in a similar slump for a while now (lectures + paper skims >> books + coding), so this is advice I'm telling myself right now. Put a stack of good books in a place where you see them several times a day. There&#x27

I've seen a very broad spectrum of research code. In general research code translates O(1e1-1e2) lines of mathematics into O(1e3-1e4) lines of code. I find mathematics easier to understand than code, so that's going to color my op

Project is super cool. If you're adding more LLM integration, a cool feature might be sending the results of allow_many="left" off to an LLM completions API that supports structured outputs. Eg imagine N_left=1e5 and N_rig

> would be a rounding error above absolute zero anyway Kind of joking: unless there are nonlinear effects near 300K? Fig 4 [1] seems to suggest that the thermal diffusivity of the mantle grows very fast as temperature declines past 300K.

I wonder how much ΔT you need at the crust to meaningfully change Earth's magnetic field by altering convection patterns in the outer core. I don't know enough physics to attempt an answer.

Talk to people in your department about where students who enter industry end up working after graduation. Your university may have a kind of "jobs fair" in Autumn where companies come to recruit. Look into those companies and fin

Cool, EDGAR is an amazing public service. I think they use Akamai as their CDN so the downloads are remarkably fast. A few years ago I wrote an SGML parser for the full SEC PDS specification (super tedious). But I have trouble leveraging m

Don't know about Jane Street, but that sounds like a general problem. If options & futures are more liquid than the underlying, someone will be tempted to nudge the underlying. Bond ETFs and their options chains seem like another l

Papers with code for quantitative finance. Still just thinking about it. Replicating research is a great way to learn a field. >90% of the work to replicate academic research in quant finance is data collection and cleaning. Academics ha
