I think your per-axis std normalization is likely doing a big pile of the work —- it’s fairly well-known that “wrong” PCA, setting sigma=Id or just taking a square root, gives better embeddings than the un-normalized version. It would be wo

I did a goodly chunk of vibe coding over the summer and I found that the best language for me was Rust implementations with Python bindings for interface. A few reasons: - Everything about rust enforcing correctness catches lots of bugs - U

Another completely viable solution (other than adding extra starch) I’ve found is to sprinkle a bit of sodium citrate (the sodium salt of citric acid, a common food additive and cheap on Amazon) over the cheese before adding to the pan. Thi

A good way to understand why cosine similarity is so common in NLP is to think in terms of a keyword search. A bag-of-words vector represents a document as a sparse vector of its word counts; counting the number of occurrences of some set o

Convergent sequences are always Cauchy; for metric spaces, compactness and sequential compactness are the same.

The key question here isn’t so much whether GPT-4 beats the actual human decks as much as what it had to fabricate to do so. The humans are probably constrained by things like “reality” and “what their business has done in it” while GPT-4 c

Very let down by the title -- why no ancient Roman abstract algebra?

Sure. Moonshine I know a lot about, relative to physics at least. Given that I now work somewhere that specializes in term embeddings, it kind of feels like I've spent half my life injecting stuff into vector spaces...

Hey, I'm a mathematician, not a physicist. We tend only to get as far as "oh yeah, here's all this pretty math we care about. I hear it has some applications to physics..."

Presumably the extra credit is that the binary Golay code is closely related to the Leech Lattice, and thus to the entire moonshine situation, which gets you to string theory. See: https://en.wikipedia.org/wiki/Leech_la

Very company dependent. At Luminoso ( http://luminoso.com ), we live in Python, with varying doses of Javascript for frontend, very little R (but some of us know it), Java and C++ are pluses (for working with other people's s

Indeed -- it's struck me recently how Wes was probably among the first (if not necessarily number one, if only because of ill-definedness) people to make computers smaller. Looking back at the sixty years since he began, it's been

Quite. Minsky was actually advisor to my company, which is based in part on his notion of common sense computing. There is much to mourn recently.

He'd talk about computers for fun, at least. But try to convince him that the internet actually worked and you'd have a whole evening's conversation on your hands...

It's a reference to a story about Ramanujan, who once (remarkably) told G. H. Hardy that 1729 wasn't a boring number because it was the smallest number that could be expressed as the sum of two cubes in more than one way. Sometime

Everyone has stories, most better than me. I find my most vivid memory of experiencing him as an adult was that every time you spoke with him he'd have had some completely flabbergasting new life experience you'd never imagined. H

I'm his grandson, not his colleague, so far be it from me to say he was a great man, but he was a great grandfather and an inspiration. He taught me an enormous amount, from logic to just how hard it can be to get people to adopt new t

I couldn't possibly agree more in general, though of course I'd quibble with many of the specifics... As to stodginess, I'd say there's a big difference between personal/small commercial lines and the big ticket ent

This is an impact of the default Unicode normalization, which is set to NFKC. This normalization is lossy for things like the ordinal indicator and trademark symbol; if you'd like to keep the ordinal indicator unchanged, use NFC normal

One meaningful point: we're early-stage and we bought a booth and we seem to be getting great value out of it, but we have a very specific target audience not mentioned by the original poster: digital marketers. At least the interactive p
