the thing about increasing risk concentration (ie concentrating the probability mass that a bad thing happens) is that until the bad thing happens people can smugly say "this is making us so much safer, the data says the number of occurrences of the bad thing has gone down. I am very smart"

say you want to be able to tell whether a thing is in the top X percentile in terms of frequency of occurrences. the standard way to do that is to use a count min sketch and a heap, where the size of the heap is the expected number of items in that percentile and on adding an item if per the […]

are there any unit test frameworks that have utilities for doing statistical tests? there are a lot of situations where I want to say "changes in this function's input should be correlated to changes in this function's output" and have the unit test be a monte carlo sampler

tokenization is currently the bottleneck for the search indexer, but the tokenization algorithm is already O(ℓn) where ℓ is the number of lengths of tokens in the dictionary, and almost all operations are cache local bloom filter lookups, so I don't think it's possible to do any better. I could […]

modern language models go back to Collobert and Weston (2011) but for some reason that paper hasn't entered the general discourse the way transformers have

a problem that is understood is already solved. you don't solve problems by understanding them, you solve problems by taking stabs at them and adjusting direction every time they punch you in the face https://mastodon.social/@mhoye/110714642403510178

You can't solve problems you don't understand with software you don't understand. It feels weird needing to repeat that.

It isn't smart to try to hire above average skilled people and then encourage them to communicate through any medium that munges what they wrote into what software guesses an average person would have been likely to write.

what's the name for the sample cluster thing a lot of IDM does, where you have a dozen or two instances of the same sample with random pitch and maybe delay offsets?

appollo has athene (the insurance company) to pass off their bad loans to retirees by wrapping them up in annuities. does blue owl (who is even more exposed to AI datacenters) have a similar setup?

There has been outrage as the @ACM rolls out AI generated summaries of papers. This is doing AI exactly wrong by replacing valuable, peer-reviewed content with a possibly inaccurate summary.

It's still not too late to correct it though, and I've penned down my recommendation for what the ACM […]
