This is relatively subtle stuff, but here's an attempt at describing the general problem. I'm going to describe the deterministic case, but the probabilistic case is effectively the same. Let's say you have a bug you suspect

All-pairs is for _pairs of features_. For subsets you're in much deeper trouble because of the exponential dependence on N. For a fixed polynomial dependence, you can get clever and let tail bounds eventually work for you, but for expo

omg, I would pay $100 for something like this on the Chapman Stick fretboard. ("which Stick fretboard and which tuning" of course are the hard questions on said weird instrument... but 10-string Baritone Melody please? :) )

The language semantics matter greatly. GHC with `-fllvm` is not going make Haskell any easier to compile just because it's targeting LLVM. Fortran is (relatively!) easy to make fast because the language semantics allow it to. Lack of p

Yes, exactly. There's a real-life example of an author group who got sufficiently annoyed at a reviewer requesting an inappropriate subgroup analysis: https://www.thelancet.com/journals/lancet/article/PII

Sorry. You do mention a linear systems response, and that's what I meant. In that setting, the eigenvectors work as a generalized forward and inverse fourier transform, and the eigenvalues form the transfer function you allude to in th

Interesting paper. I have a question about the claim in 6.2 that attention matrices are SPD, if you don't mind my asking. It seems to me that accepting the empirical result that the eigenvalues are positive isn't enough to get a F

I don't know why you're getting downvoted. I read the methods section and the stats model doesn't seem to adjust for "calories consumed after dieting stopped". Those calories, as you point out, can be correlated wit

Ask it the other way around, "Why is the 8K context only twice as cheap as the 32K context?" and your original answer is clearer: because they think the demand curve supports it. Price is not determined by cost, but by how much pe

by cscheid 4y ago
Not _any_ problem, but the _specific_ problem of determining how many arbitrarily placed points (cherries) can be split by a given shape of hypothesis classes/classifiers (knives) is literally the definition of VC-dimension, yes :)

by cscheid 4y ago
And if you think sufficiently hard about curved knifes and cherries on high-dimensional pies, you end up studying machine learning theory ( https://en.wikipedia.org/wiki/Vapnik%E2%80%93Chervonenkis_di... )

Read the whole paper! Seriously, do it. The author is being cheeky with showing how an academic urban legend gets made and it takes the whole paper to get the punchline.

You can't do graphs without numbers, so the history makes sense. Finite graphs are relations over finite sets. You can't do much with finite sets before inventing numbers.

That would make it not really what distill was about. Concretely, the article my students wrote wouldn’t have been possible - it was literally proposing a new visualization method and showing a real implementation on the web.

Distill was one of the best experiments in publishing of the last decade, no irony. Unfortunately, it’s worth reflecting on why they are on a hiatus that I fear will be (understandably) permanent. When I was an academic, I had the privilege

This makes me so happy to read. I had the privilege of working on the same lab as Neil (and Dave Applegate, another notable person in OEIS). No exaggeration at all to call them geniuses, you hang out with them for 5 minutes and know they&#x

Just another upvote for these. They're great if you don't have room for a dumbbell rack, and (of course) they're lighter than the standard dumbbell set.

Yeah, I mostly agree. I would put it slightly differently, and I honestly don't know if I'm being kinder or not. I'd say that in this book, Feyerabend is being a troll. He's out to get a reaction out of you more than to

That's not true. The page rank is read from the eigenvector, and is the value associated with the given vertex (ie web page). There are as many page rank values as there are web pages, but only one eigenvector from which to read: the d
