There is a Sanjeev Arora paper "A Theory for Emergence of Complex Skills in Language Models" (https://arxiv.org/pdf/2307.15936) on this subject. The key idea is there is cross entropy (how "surprised" the model is with the "correct" next token, lower is better), some of which is inherent in the language and therefore unavoidable, and the rest is model error, and that this portion of the cross entropy is reduced with scaling.

And as scaling reduces a model's excess entropy, the model can become good at combinations of skills much faster than you would expect if it had to separately see and memorize every combination. They call this "slingshot generalization".

Am I allowed to stay with a relative or a friend when I visit their town? I am totally ignorant of local norms, maybe I should be in the Holiday Inn next door instead?

aside: me after reading the headline: Shouldn't that be Octopii?

But no! "The plural form octopii is doubly incorrect. Firstly, octopus derives from Greek, not Latin; its etymologically-consistent plural form is octopodes. Secondly, even if octopus were a second-declension Latin noun, the plural form would be octopi; in the correct plurals radii and gladii, with which octopii is analogous, the first ‘i’s are part of the words’ stems (radi- and gladi-), and not their case endings — for octopii to be the plural, *octopius would need to be the singular."

Thanks wikipedia.

TIL!

> The nominal mode enables motion through the water at 3.6 km/h, and for speed-seekers, the SEABIKE can reach a maximum of 7.9 km/h – much faster than normal swimming speeds or even flipper-assisted swimming.

Pretty fast, but "superhuman"? For short distances Michael Phelps can swim faster :)

New comment by neerajk in "Why doctors pay millions in fees that could be spent on care"

neerajk — Tue, 15 Aug 2023 17:50:32 +0000

Possibly naive, but hopefully trying to reason from first principles:

The insurance companies are the ones paying for care. The hospital systems are the ones charging for care. The entity that pays for care has every incentive to keep costs _low_. The entity that charges for care has every incentive to charge as much as possible. i.e. The ire of consumers should be directed at hospital systems rather than insurance companies.
