From grandparent: > What's with the "AI" positioning? It's an implementation detail that’s abstracted away from end users, but also one of the enablers/answers to the "why now" question on a business le

Yes. Two of the more straightforward ones involve market impact and spreads. Short term market impact results from supply and demand imbalance. As such, multi unit blocks are either an asset or a liability, depending on how you're posi

Hi, Kelly and Steve here, founders of OneChronos. Happy to answer any questions. In short, we're applying combinatorial auctions to financial markets. Combinatorial auctions are generally speaking computationally intractable. Our art

Etherscan has an option for linking the source [1], in which case they compile it and verify the result against the bytecode that's publicly available. Edit: the source itself is based off of [2]. The custom part is ```contract PonziCo

Nope, just an evening hack :) As for what's next, I'm adding time as a dimension for analysis, entity recognition, and an .mbox source for e-mail. That aside, feature requests and PRs welcome!

I'm not sure about that error specifically, but I just simplified the environment.yml file s.t. only direct project dependencies are included. Hope that helps!

Hi, author here. Happy to answer any questions. Check out the notebook itself for a sample analysis. If you're on mobile, make sure to request it as a desktop site or GitHub will render it raw.

Sorry about that - I'm relying on the notebook itself as the example. If you open it up, you'll see a full analysis.

I switched from MathJax to a middleman + execjs + KaTeX pipeline for my static sites earlier this year, and I'm very happy with it overall. KaTeX isn't 1-1 with MathJax when it comes to syntax support; I was surprised to see that

It's a community that knows low level CS/AI well. The chess programming wiki [1] is quite the knowledge hole for everything from bit twiddling hacks to obscure search algorithms. [1] https://chessprogramming.wikispaces.

There are very interesting and fairly recent results on causal discovery under additive noise models [1]. Although such models aren't universally applicable the underlying concept is intuitive and a good fit for many problem domains. O

Right, my comment retarding truth tables was only in reference to combinatorial logic. That said, pure circuit models of computations exist, and are interesting from a theoretical standpoint at least. They don't translate to hardware,

Thankfully "messing" isn't the word I would choose for most market participants but you're describing the algorithmic game theory that goes into designing a good execution algorithm.

For that matter, cuckoo hashing [1] in general is an interesting topic. Take a look at its application to cache oblivious dictionaries [2]. They work quite well in practice, especially for space constrained hash tables (e.g. caches). [1] h
